Blown Furnace Fuse: What You Can Do

Why would a furnace fuse blow Has your home furnace blown a fuse or two? While you may think that a tripped breaker or a blown fuse may not be a big deal, there are several situations where you may risk complex failures unless you address the reason why your furnace keeps blowing fuses.

Since some of these reasons can be quite serious, it is advisable to reach out to furnace repair professionals if your heating system in San Diego keeps tripping breakers. In the meantime, keep reading to learn about the common culprits of blown furnace fuses.

Why would a furnace fuse blow?

Here are some of the most common reasons why your furnace may be blowing fuses:

Damaged wiring

Poorly connected and/or damaged wires can cause your furnace to short circuit and blow a fuse. If this is the case, it is generally best to let professionals inspect the wiring and resolve the issue.

Dirty air filters

A lack of maintenance can lead to dust and debris accumulating on the air filters. Unless the air filters are regularly cleaned or replaced, the grime may migrate to the blower motor, causing it to overheat and lead to a high limit failure. The best way to prevent this issue is to have your furnace maintained on a regular basis.

Thermostat metal frame

Thermostats surrounded by metal frames have been known to cause furnaces to blow fuses. This happens when the wiring inside the thermostat touches the metal frame, creating voltage issues and potentially blowing the control board. If this happens, you’ll have to reach out to professionals to fix the problem before being able to use the furnace again.

Worn or faulty components

When failing or faulty, the following furnace parts may cause the unit to short circuit:

If you suspect any of these furnace issues, don’t hesitate to contact your HVAC professionals of choice if you wish to prevent unnecessary damage to your unit and expensive repairs.

How do I know if my furnace fuse is blown?

Before you go looking for a new fuse, you should make sure that you’re actually dealing with a blown fuse and not some other issue. Checking your furnace fuse is a relatively simple procedure that won’t take much of your time. Still, reaching out to professionals to inspect your furnace may be the better cause of action if this isn’t the first time you’ve had this problem with your furnace.

Start by making sure that the furnace thermostat is set to “heat” and a suitable temperature. If so, check the power switch and see if it’s in the “on” position. If both of these are in order, it is time to check the breaker or fuse box.

Where is the fuse on a furnace?

In order to check and replace the fuse, you’ll first need to locate it. Hopefully, you already have an idea where the electrical panel is located and whether you have a circuit breaker or a fuse box. If you don’t, check your garage, basement or closet and try to find a grey metal box.

Circuit breakers

If your home has a circuit breaker box instead of fuses, each circuit breaker should be connected to rooms in your home or individual appliances. Your furnace most likely has a dedicated circuit of its own. The breakers are usually labeled, but if not, it will be quite easy to tell which breaker has tripped, as it will probably be in the opposite direction of the others.

Before you attempt to restore power, dry off your hands completely and flip the tripped circuit breaker with one hand. This should restore the power unless you’re facing a more serious issue with your furnace.


If your furnace has a fuse, it will probably be located in the control box with the blower. BIf you can’t locate it, the transformer may have burned up and will need to be replaced.

Once you’ve located the fuse, check its wires to see if they’re broken or look for signs of discoloration or cloudiness. If so, you have a blown fuse that will have to be replaced. You can also use a multimeter to check if the fuse is blown. A good fuse normally has nearly zero resistance (in ohms), whereas a blown fuse will show no reading.

How do I change a fuse in my furnace?

If you’ve determined that your furnace fuse is indeed blown, you’ll most likely be able to replace it quite easily. However, you’ll have to make sure to purchase a fuse that has the same wattage rating as the previous one. Check the manufacturer’s instructions manual to find information on how to properly replace the furnace fuse.

While most homeowners will be able to successfully replace a blown fuse, it is crucial that you contact experienced HVAC technicians to inspect your furnace system if it keeps tripping breakers or blowing fuses. This is because there may be a more complex issue causing the fuses to blow that might result in serious damage to your unit if not addressed properly.

Delayed Furnace Ignition: Should You Be Worried?

What does delayed ignition sound like? Is there a reason to worry about the noises your furnace is making?

If your heating system is producing loud and explosive sounds, it’s a natural cause for concern.

Here is some important information about furnace delayed ignition and whether you should reach out to a heating contractor in Riverside to take a look at your heating system.

What does delayed ignition sound like?

When excessive gas builds up in the combustion chamber of your furnace, the delayed ignition will cause a small explosion. This results in a loud bang or boom that can be startling for homeowners. A similar sound can also be caused by expanding and contracting ducts.

What causes delayed ignition on a gas furnace?

You are most likely to notice a delayed ignition when you turn on your furnace, especially if you haven’t used it for a while. This is why delayed ignition usually happens in the fall or late spring when you don’t use it every day.

But why does it happen? In general, furnaces experience delayed ignition because a build-up of corrosion, dust, or sulfur blocks gas-feeding ports and prevents the burners from lighting properly. Here’s how it happens:

Moisture buildup

Over a period of furnace inactivity, moisture tends to build up inside your system, corroding its firebox over time. If the moisture-caused corrosion builds up enough, it can block the ports feeding gas into the furnace burners. If this happens, the burners won’t be able to ignite immediately after you turn the furnace on.

Dust and lint

While moisture and rust are one of the most common causes of delayed ignition in furnaces, dust and lint can also accumulate and cause problems. This can be easily remedied by having your furnace inspected and cleaned by professionals before each heating season.

Sulfur buildup

Your furnace can also experience delayed ignition due to a sulfur build up caused by burning natural gas. If your burners or pilot light are covered in a white layer, you may be dealing with built up sulfur.

Electronic ignition problems

If your furnace has an electronic ignition system, the delayed ignition may be caused by built up combustion gas in the chamber. While your furnace is most likely equipped with a safety mechanism to prevent this, the igniter may not come on promptly and shut off the flow of the gas, causing build-up. If this is the case, you’ll probably have to have the igniter replaced in order to ensure the proper functioning of your furnace.

Is delayed ignition dangerous?

A delayed ignition does not just sound like an explosion, it is one. If you choose to ignore these small gas combustions, it may become quite dangerous.

It may cause damage to your furnace

Unless properly addressed, the delayed ignition explosions are likely to get larger over time. The greater the vibrations are, the higher the chance of the stack pipe getting loose and soot ending up all over your home.

The excess flames caused by delayed ignition can also crack the heat exchanger, one of the most expensive components of your furnace. When this happens, most homeowners choose to replace the furnace instead of replacing the heat exchanger as the latter option is cost-prohibitive and the installation process may result in carbon monoxide leaks.

It may become a safety hazard

Constant gas build-ups in your furnace’s combustion chambers can not only damage your furnace, but may also let the flames out of the chamber and cause a fire. However, modern furnaces are built with mechanisms that uphold high safety standards. Essentially, the risk of explosions and fires will be slim if you properly and regularly maintain your furnace.

How can I prevent delayed ignition on a gas furnace?

Luckily, preventing delayed ignition is not difficult. All it takes is to have experienced HVAC technicians inspect and clean your gas furnace before each heating season, typically in the fall. This will prevent corrosion and dirt from accumulating inside of your furnace and minimize the risks of gas build-up. Here’s how professionals will clean your gas furnace:

  • Cleaning the surfaces: After wiping the exterior surfaces of your furnace with a damp cloth, they will vacuum the furnace base and the burners, as well as clean the dirt and grime from other components.
  • Cleaning the blower: Your technician will carefully clean your furnace’s boiler with a small brush and a vacuum, making sure not to disturb the fan blade counterweights and the wiring.
  • Cleaning the pilot or igniter: Since a dirty pilot light or surface igniter can cause problems with your furnace, your technician will make sure to carefully blow off any dust from these components without damaging them.
  • Cleaning the flame sensors: They will also lightly clean the flame sensor using an appropriate cloth to ensure optimal performance.
  • Lubricating components: When cleaning your furnace, your HVAC technicians will apply a tiny bit of lubricating oil on your furnace’s blower motor and shaft bearings.
  • Replacing the filter: You should have your furnace air filters replaced every 3 months. If you don’t want to bother with this yourself, your HVAC technician will do it for you.

Furnace Thermostats: Problems & Solutions

What's wrong with my furnace thermostat? Thermostat issues are one of the most common culprits of furnace malfunctions. If your furnace isn’t working as well as it should, and you’ve determined that other issues such as a faulty furnace heat exchanger or dirty air filters aren’t to blame, you should inspect and troubleshoot your thermostat.

We understand the importance of indoor comfort. Ensure your heating system stays in good condition, including on nights Riverside and other inland cities are colder during winter months.

What’s wrong with my furnace thermostat?

Thermostats are complex devices designed to control the operation of your furnace.  Learn about thermostat operation and what you can do to effectively resolve issues.

Unfortunately, there are a number of frustrating issues that may make your furnace malfunction or even fail. Here are five common causes of thermostat failure:

1. Dead batteries

Like any other electrical device, your thermostat needs batteries to work. If the batteries are dead, the thermostat won’t monitor the temperature and won’t instruct your furnace to turn on. If you notice a low power warning on your thermostat, try opening up the cover and replacing the batteries. Note that you should try using AA batteries instead of alkaline if you notice inconsistent performance. This is because alkaline batteries tend to drain quickly and cause failures in your heating system.

2. Grime buildup

Your thermostat may struggle to reach the set temperatures because dirt and grime have accumulated inside of it. If this is the case, your thermostat will be unable to accurately gauge the temperatures in your home.

If your thermostat is old, you should try dusting inside its cover and use a bit of paper to remove the grime from the contacts. However, the easiest and safest way to make sure your thermostat is clean and works well is to rely on professional HVAC technicians to inspect and maintain it.

3. Aged thermostat

You are likely to experience more issues with an old thermostat than you would with a modern device. Naturally, thermostats are prone to wear and tear, and there is a greater chance of breakdowns if your thermostat is reaching the end of its lifespan. If that’s the case, consider purchasing a programmable thermostat that will ensure the optimal performance of your heating system.

4. Loose wiring

Improper installation can often result in loose wiring inside of your thermostat, and in turn, weak performance and even severe electrical issues. It is essential that you don’t try to fix wiring problems in your thermostat yourself as this may cause even more damage to your heating system. Instead, contact your go-to technicians to fix or replace your thermostat.

5. Incorrect placement

Proper positioning is crucial for ensuring good thermostat performance. In order to work properly, your thermostat shouldn’t be placed in direct sunlight or next to a heat source and should be within 5 feet of any doors. This is important because it can cause your thermostat to read incorrect temperatures inside of your home.

How do I know if my furnace thermostat is broken?

Not sure if your thermostat is causing issues with your furnace? Here are some telltale signs of thermostat problems:

  • Your furnace won’t turn on. When a thermostat works properly, it allows you to turn on your HVAC system and change its settings. If you get no response from your heating system, it may mean that your thermostat is faulty.
  • The thermostat doesn’t acknowledge setting changes. If you attempt to change the temperature settings on your thermostat, it should respond to the changes almost immediately. If it doesn’t respond after you make the changes, you may need to have the thermostat fixed or replaced.
  • Your furnace short cycles. If your furnace turns off before finishing a full heating cycle, this means that it’s short cycling and might result in inconsistent or ineffective heating. If this happens, make sure to have your furnace inspected by professionals.
  • Your thermostat “forgets” programmed settings. If you have a programmable thermostat, it should be able to remember any programmed settings for long periods of time. If your thermostat forgets these settings, you may have to replace it.

While some thermostat issues can be replaced simply by replacing the batteries, it is always a good idea to contact HVAC professionals if you notice unusual behavior with your thermostat or heating system. This way, you’ll minimize the chances of severe breakdowns and keep your unit in good condition throughout the year.

How do you reset a furnace thermostat?

The procedure for resetting a thermostat may vary by model. While you can (and should) refer to your thermostat manufacturer’s resetting instructions, most thermostats can be reset in one of the following ways:

  • Flip the batteries: Installing the batteries backwards for five seconds and reinstalling them can be an effective way to reset your thermostat.
  • Flip the circuit breakers: Turn off the thermostat on the device itself and go to your circuit breaker box and flip the HVAC system breaker. Wait 30 seconds before you flip it back on and check if your thermostat is working properly.
  • Paperclip method: Use a paperclip to press the recessed reset button on your thermostat, if it has one. Hold the clip in for 5 seconds before releasing it.

Furnace Ignition Lockout: Causes & Solutions

What does ignition lockout fault mean? Is your furnace continually shutting down? Has it stopped responding entirely after several attempts to turn it on? If so, your furnace may be in an ignition lockout and must be reset.

Modern furnaces are equipped with a number of safety sensors used to keep the proper functioning of the unit in check. If any sensors detect an unsafe condition, the furnace shuts down to prevent safety hazards or damage to the unit. Unfortunately, the furnace will remain in this state until you or your local Murrieta heating repair technician reset it manually.

What does ignition lockout fault mean?

When a sensor detects an unsafe condition, the furnace controller will shut off the power and fuel to prevent hazards. This is known as an ignition lockout, a condition that can be caused by a number of different sensors found in your furnace. If your furnace is locked out, it will most likely remain in that state until it’s reset. Many homeowners send their furnace into a locked out state when they attempt to get it running several times in a row without success, unaware that the sensor has detected an unsafe condition.

What causes furnace ignition lockout?

Most of the time, furnaces go into ignition lockout because of issues with flame sensors, igniters, or limit switches. Here are the most common lockout culprits explained.

Defective flame sensor

Defective flame sensors are one of the most common causes of lockouts. When your furnace begins to start, the sensor checks for the presence of fire. If the sensor is faulty or dirty, it won’t be able to detect the flame and the controller will stop the ignition sequence. Most modern furnaces will let you start the furnace two more times before it goes into a lockout.

Faulty igniter

The igniter is another frequently encountered lockout culprit. If your furnace igniter does not activate within a couple of seconds, the flame sensor won’t detect the flame, and the controller will stop the furnace from starting. After the third attempt, your furnace will most likely go into a locked-out state. If your gas furnace has a pilot light, the lockout may also be caused by its failure to light the main burner.

Limit switch response

Your furnace also has a limit switch that monitors heat exchanger temperatures and fuel pressure. If the temperature is too high or the pressure too low, the limit switch will close, instructing the furnace to shut down and enter lockout mode. A dirty filter may also cause the limit switch to trip by reducing the air flow. If you have a modern furnace, you may be able to tell what caused the lockout via the status code lights.

What is the difference between a hard and soft lockout?

There are two main types of furnace lockouts you should know about – a hard and a soft lockout. As we’ve already explained, your furnace controller will stop the ignition sequence and prevent unsafe operation if the sensor doesn’t detect the flame within a set time period. This semi-shutdown is known as a soft lockout, and you will be able to attempt to start the furnace again, usually two more times.

A hard lockout happens after several repeated soft lockouts. For most furnaces, you will have three attempts to relight the unit before it goes into hard lockout. If this happens, you will have to reset the unit manually. The best way to do this is by calling your go-to HVAC technicians to perform the reset sequence.

How do you fix a furnace ignition lockout?

The exact procedure for getting your furnace out of lockout will depend on the culprit. Here’s what you can do before resetting your furnace:

  • Clean or replace the flame sensor: Inspect the furnace flame sensor to look for cracks and signs of damage. If you notice only soot or slight corrosion, follow our guide on cleaning flame sensors. If that doesn’t fix the problem, replace the sensor and try again after you restore the furnace from lockout.
  • Clean or replace the air filter: A clogged air filter can prevent adequate air supply to the system, tripping the limit switch. Simply replace the filter and see if the issue has been resolved. It is generally advisable to replace or clean furnace air filters regularly to ensure the safety of your family.
  • Inspect and clean the vent pipes: Look for debris and signs of obstruction inside your vent pipes and clear any blockage you find. If you are unable to clear the blockage, the best course of action would be to call HVAC experts to replace the clogged pipe section.

Resetting the furnace

Regardless of the culprit, you will have to perform a reset procedure to get your furnace out of lockout. Most modern gas furnaces can be reset by turning off the power, waiting around 20 seconds, then switching the power back on. Other furnace models may exit lockout after 1-2 hours and attempt to power on again. If your furnace has a pilot light, you may need to relight it following the manufacturer’s instructions.

If none of the above-mentioned works for you, the best course of action is to reach out to knowledgeable HVAC technicians and have them inspect your unit and perform the necessary tests and repairs to get your furnace out of lockout.

Furnace Flame Sensor Faults: All You Need to Know

Do flame sensors wear out? Does your gas furnace shut down shortly after you turn it on? Does this happen several times before the furnace shuts down completely? If that is the case, you may be dealing with a furnace flame sensor problem.

Flame sensors are simple devices designed to confirm the gas valve is only open when there is a fire present, preventing harmful gas buildup. These sensors are typically found in modern furnaces, and other gas-fired heating systems.

Fortunately, problems with flame sensors are a common occurrence among homeowners, and don’t often require complex heating repair. The following brief guide can help you determine if your furnace flame sensor is dirty or faulty, and whether you need expert HVAC assistance in Murrieta.

Do flame sensors wear out?

Flame sensors wear over time. However, often the problem is a dirty sensor, rather than a broken one. Since these sensors are designed to have a low tolerance for reading variations, they might misread from the slightest carbon coating. As most furnaces are located in dusty areas, such as basements or laundry rooms, the airborne particles can easily stick to the flame sensor, burn and cause carbon buildup.

What happens when a flame sensor goes bad?

If cleaning the sensor doesn’t restore your furnace to working condition, a replacement may be in order. If this happens, it is advisable to contact a professional HVAC service provider to inspect your furnace and resolve the issue.

Without a flame sensor, your furnace will keep emitting gas even when there’s nothing to ignite it, resulting in hazardous gas buildup. If your flame sensor is dirty or faulty, it will automatically shut down the heating unit if it doesn’t detect a flame.

Most furnaces will go into a safety ignition lockout when a shutdown happens three times. In addition to being highly inconvenient, continuous tampering with a bad furnace flame sensor can cause issues with other furnace parts and reduce overall efficiency.

How do I know if my furnace flame sensor is bad?

Not sure how to tell if your flame sensor is faulty or just dirty? Follow these guidelines to determine which is true:

  • Switch off the power to your furnace
  • Close the gas valve
  • Take out the mounting screw
  • Carefully pull out the sensor
  • Inspect the sensor: if the insulation is intact but appears sooty, burnt or slightly corroded, it might only require cleaning
  • If the sensor insulation is missing pieces or cracked, a sensor replacement is needed

Replacing a flame sensor is a simple procedure, but it’s advisable to outsource the job to professionals, lowering risk for preventable issues. HVAC experts can also thoroughly inspect your unit to determine any additional problems and prepare your heating system for the upcoming winter season.

What can I use to clean a furnace flame sensor?

It is likely that your flame sensor problem can be fixed with a simple cleaning. The easiest way to do this is to rely on your preferred HVAC technicians in Murrieta to clean the sensor during your regular furnace tune-ups. If you decide to do it yourself, you’ll need:

  • Wrench or driver to remove the 1/4  hex screw (exact tool needed may depend on the type of screw)
  • Light grain sandpaper, steel wool, or a wire brush
  • Clean and dry cloth or paper towel

First, shut off the power to the furnace and locate the sensor in the burner assembly. It is a thin, typically bent, metal rod placed in front of the furnace flame stream. Once located, use the driver or wrench to remove the screw and access the sensor. Next, use the sandpaper, steel wool, or wire brush to rub the rod gently and remove the carbon buildup, making sure you don’t go overboard. Once you’re done cleaning, use the cloth or paper towel to wipe the rod down.

How do you test a flame sensor?

During routine furnace tune-ups and check-ups, your HVAC technicians will troubleshoot your flame sensors to ensure proper performance and safe functionality, as well as prevent more serious damage to the unit. Here’s how it’s done:

  • Step 1: Unplug the device and locate the sensor. If the unit can’t be unplugged, use the breaker found in the breaker box to switch off the power.
  • Step 2: Use a driver or wrench to unfasten the screw that holds the flame sensor in place and carefully pull it out.
  • Step 3: Use a multimeter to show resistance by touching the probes to the white and blue wire ports found on the sensor. The device should detect low resistance.
  • Step 4: Take the flame sensor and press its open end against a test lamp or a 60 watt bulb. Check the multimeter and see if it shows high resistance.
  • Step 5: If the multimeter doesn’t detect a resistance discrepancy when placing the open end on a light source, the flame sensor will have to be replaced.

What makes a good heating and cooling company?

So, what makes a great heating and air conditioning company? Homeowners tend to look for the following characteristics when searching for HVAC contractors:

Trained & certified technicians

Reliable heating and cooling technicians should have all the necessary training and certification. Although experience is another important factor, seeing that your HVAC technicians are certified and properly trained shows that they have the knowledge and skill needed to repair, replace, or install your heating or cooling system properly.

For instance, NATE-certified technicians possess both theoretical and real-world knowledge of all kinds of HVAC equipment. If you want to make sure that your HVAC contractors are competent, make sure to check if they have any sort of certification that may prove their expertise.

Experience with a wide array of HVAC systems

There are a multitude of HVAC systems available on the market today. A good heating and cooling company should be able to adapt their approach depending on the type and model of your system. Whether you have a ductless air conditioning system or an older furnace, a knowledgeable technician should know how to repair or replace it expertly and efficiently.

Additionally, your contractors should offer maintenance and tune-up programs for both your cooling and heating system if you wish to stay comfortable all year round. Of course, not all HVAC companies service all kinds of equipment, so make sure to check this first before you hire.

Honesty and integrity

Contractors who respect their customers and value their trust tend to put more effort into perfecting their services. Your HVAC company should strive to meet your needs and surpass your expectations with each visit, whether you are a first-time customer or a long-standing client. Their dedication to making you happy should never waver.

Personable customer service

An amicable and dependable customer service staff is a must for any serious heating and cooling company. Even if the technicians are highly skilled and experienced, you surely won’t appreciate their expertise if the rest of the team is not willing to listen to your feedback and address your concerns.

In fact, good customer care is one of the most important areas that any HVAC company could work on. You should look for contractors who are dedicated to building loyalty and trust with their customers, listen to what you have to say, as well as keep you in the loop regarding any fixes they perform in your home.

Great prices & financing options

The cheapest heating and cooling company is rarely the best. Reputable HVAC contractors should offer you reasonable prices for their services, as well as give good guarantees on their work. Of course, some HVAC contractors overprice their services, so make sure to ask around if you’re not sure about the quality they bring to the table.

Additionally, your HVAC contractor should offer a number of financing plans that fit your budget and give you the best value for your money. For instance, they might offer no money down financing options for some of their equipment.

Furnace Filters: All You Need to Know

Can you run a furnace without a filter? Your furnace needs a filter in order to purify the air and make sure that the system runs smoothly. Using a furnace with a dirty filter or running it without one can cause a whole range of issues with your heating system, so make sure to learn all about furnace filters if you wish to keep your family safe and prolong the lifespan of your unit.

Unless you wish to deal with furnace issues in the middle of the heating season and rely on heating service in Murrieta far too often, you need to check your furnace regularly. Read on to learn more about why furnace filters are so important!

Can you run a furnace without a filter?

The simple answer to this question is no. While you can technically operate your furnace without a filter, doing so can cause serious harm to both your heating system and your health. Of course, your furnace is unlikely to break down after just one day of use without a filter, but prolonged use would certainly have a detrimental effect.

What will happen if you run your furnace without a filter?

Running your furnace without an air filter can lead to a great number of issues with your furnace. Here are some of the most common issues with using a furnace without a filter present:

  • Poor indoor air quality. Without a filter, all the harmful particles in the air will stay there. Breathing in poor-quality air for longer periods of time can cause allergies, asthma and other respiratory issues.
  • Particle buildup can cause malfunctions. The filter in your furnace is there to trap airborne particles and stop them from accumulating on the furnace components. Without it, all the debris and dirt will quickly build up and result in malfunctions and costly repairs.
  • Safety hazards. Particle buildup on your furnace’s components can create fire hazards, as well as lead to moisture and mold problems if left unchecked for too long.

Will a furnace run with a dirty filter?

Dirty filters are one of the most common culprits of furnace issues. In fact, a clogged filter can cause a wide range of problems with your heating system, both simple and complex. Here’s what a dirty filter can do to your furnace:

Inadequate heating

A filter that is too clogged with debris and dust will make it harder for the blower fans to push the air through. This results in a decreased airflow and uneven heating throughout the house. If you’ve realized that there are spots of hot or cold air in your home, check and clean/replace your furnace filter regularly.

Increased utility bills

The extra effort your furnace has to put in in order to keep your house warm with a dirty filter will naturally result in increased energy consumption. If you’ve noticed that your utility bills are higher than usual, a clogged filter might easily be the culprit.

Heat exchanger issues

Another common problem with dirty furnace filters is that they can lead to your heat exchanger cracking. This is because there won’t be sufficient air blowing over it, meaning that the excess heat might start building up inside the heat exchanger. This puts stress on the exchanger, causing it to crack and possibly allowing carbon monoxide into your home.

Unhealthy air

Your furnace filter is supposed to help control the dust and debris present in your home. If it’s clogged, it won’t be able to perform its primary function, allowing the germs and dirt to circulate throughout the air. This might be particularly dangerous for any family members who have respiratory issues such as asthma or allergies.

Furnace breakdowns

Since a clogged furnace filter will inevitably cause your furnace to overwork itself, it is very likely that some of its components will overheat and eventually break down. Unless you want to have to deal with furnace failures when you need it the most, make sure to check and replace/clean your filters each month.

Can you put a furnace filter in the wrong way?

Unfortunately, it’s not uncommon for furnace owners to put in the filter backwards and create a series of issues with their furnace as a result. Putting in a filter in the wrong way will decrease the efficiency of your heating system and result in higher energy bills. Basically, an improperly placed furnace filter cannot perform its primary function, meaning that it will cause all the same issues that occur when you run your furnace without a filter.

Which way does the air filter go in a furnace?

If you want to prevent filter-related problems with your furnace, you should know how to properly insert your furnace filter. Follow these steps:

  • Remove the existing filter from the furnace.
  • Insert the new filter in the direction indicated by an arrow on the filter label. The arrow shows the proper airflow direction and should always be inserted facing the furnace and facing away from the return duct.
  • You can also draw the arrow on the furnace with a marker and indicate the filter size and the proper airflow direction for easier replacement.

Replacing the air filter regularly is essential for ensuring the optimal performance of your furnace. While the procedure is not exactly complex, it can be confusing if you’ve never done it before. If you have any doubts about using your furnace properly, you can always reach out to professional furnace technicians who can replace your filter for you and ensure that everything is in order.

Heating System Efficiency: Why It’s Important

Maintaining a comfortable temperature in your home during the winter without an efficient heating system can easily result in considerable energy expenses. In fact, many homeowners across the U.S. struggle to heat their homes efficiently and save on their energy bills.

When choosing the right furnace or heat pump for your home, efficiency should be at the top of your priority list. Experts for heating services in Temecula recommend purchasing a heating system with a high efficiency rating in order to lower energy bills during the winter and help save the environment in the process. Read on to find out what the most efficient heating systems are!

Why is heating system efficiency important? What is the most efficient heating system

Picking an efficient heating system is essential if you wish to cut down on your energy expenses. In fact, the most efficient heating systems on the market can cut your energy expenses by a staggering 70%. This means that investing in a more expensive but efficient heating system may be a smarter financial decision in the long run than going with a cheaper option.

High-efficiency systems are also a great option if you care about protecting the environment as they use less fuel and waste less heat. Just keep in mind that your new furnace or heat pump should be properly sized for your home in order to bring you significant savings.

What is the most efficient heating system?

Different types of heating systems all have their pros and cons in terms of efficiency. Here’s how heat pumps, furnaces, and boilers differ in this respect.

Heat pumps

For homeowners who live in moderate climates, heat pumps are by far the most efficient option available on the market. Here’s why:

  • They heat your home in the winter and cool it down in the summer.
  • They use less electricity but produce 4 times as much energy.
  • They don’t generate harmful exhaust gases.
  • They are safe to use.
  • Geothermal heating systems can cut your energy bills by 70%.

Furnaces Why is heating system efficiency important

While older furnaces aren’t the best in terms of efficiency, newer furnace models use modern technologies that can bring great savings if you choose the right model. Here’s what characterizes modern furnaces:

  • Natural gas furnaces are very cheap to run.
  • Electric furnaces are safer to use but less efficient.
  • Furnaces with an AFUE rating higher than 90 percent are extremely efficient.
  • They are the most common option in American households, with a myriad of models available on the market.


Boilers heat your home by circulating hot water via radiators and pipes throughout your home. Although they aren’t as popular as furnaces and heat pumps for residential heating, boilers can be a great option if you go with a model that has an AFUE rating that’s 90 percent or higher. In fact, there are boiler models with efficiency ratings as high as 95 percent available on the market.

What are the different types of furnaces? What are the different types of furnaces

Before you decide on the model of your new furnace, you should first learn about all the different furnace kinds that are available on the market. They come in four main types:

  • Gas furnaces are the most common heating option in American households. They are relatively low-cost, highly efficient, and heat evenly.
  • Oil furnaces are often used by homeowners who don’t have access to natural gas. Typically, they are less efficient than natural gas furnaces but cost significantly less.
  • Electric furnaces tend to be smaller than other types which may be a plus if you don’t have much space. They are much cheaper to purchase upfront but are significantly less efficient than other furnace types.
  • Propane furnaces are a good option for homeowners who don’t have access to oil and gas. They are more efficient than oil and electric furnaces and have a long lifespan.

What is the best kind of furnace to buy?

Which type of furnace you pick for your home will largely depend on your heating needs, your budget, and your location. Here’s what you should also think about when shopping for furnaces.

Pick the correct size

In order for your furnace to heat your home effectively, you will have to get a furnace that’s just the right size. As the size of the furnace can depend on a great number of factors, it’s best to leave the task to experienced HVAC professionals.

Ask around

Make sure to browse the web and read customer reviews for different furnaces. You can also reach out to HVAC experts and get insight from them too. They will consider your heating needs and tell you which type and model of furnace will be the right choice for you.

Consider your location

Since certain types of furnaces are dependent on different energy sources that may not be readily available everywhere, your location may determine your furnace options. For instance, oil furnaces are found most commonly in the northeastern part of the U.S., while gas furnaces are a better option in other areas.

Which is better, gas furnace or electric furnace?

When choosing between a gas furnace and an electric furnace, there are several factors you should take into account. Each option has its pros and cons that you should consider before making the decision.

Natural gas furnaces:

  • Use cheaper fuel;
  • Have higher efficiency ratings;
  • Last up to 20 years;
  • Are more expensive and challenging to install;
  • Need regular maintenance;
  • Make quite a bit of noise;
  • Aren’t the best in terms of safety.

Electric furnaces: 

  • Are easier and cheaper to install;
  • Don’t need much maintenance;
  • Are safer and less noisy;
  • Last up to 30 years;
  • Use more expensive fuel;

Furnace Won’t Turn on? Here’s What You Should Do


A furnace breaking down in the middle of winter is a considerable inconvenience, no matter how you look at it. If you’ve found yourself in this unlucky scenario, you’re probably unsure how to approach the issue safely and efficiently.

Luckily, your go-to heating repair service in Temecula is here to make sure your furnace stays in great shape during the coldest months of the year. Read on to learn what to do if your furnace won’t turn on!

What do you do when your furnace won’t turn on?

When faced with a furnace that won’t turn on, there are a couple of checks you should make first in order to see if the issue will require professional help. Here’s what you should do:

  • Check the thermostat. Your thermostat may be set on the wrong setting or was reset due to a power outage. Make sure the thermostat is set to heat and set it to a temperature 10 degrees warmer than the room temperature and see if the furnace turns back on.
  • Check the breakers. Your furnace might not be turning on because of a tripped breaker. Find your breaker panel and flip your HVAC breaker off and then back on to see if that fixes the issue.
  • Check the gas supply. Your furnace may not be turning on due to a lack of fuel. Try turning on another gas device, such as the stove. If it doesn’t turn on either, contact your gas provider.

Can a bad thermostat cause furnace not to work?

Troubleshooting your thermostat should be one of the first steps to take if your furnace won’t turn on. Perform the following checks if you suspect the thermostat may be the culprit.

Check the settings

A thermostat that is set to a lower temperature will stop the furnace from working. Try raising the setting and see if the system powers on.

Change the batteries

Sometimes, fixing your furnace issue can be as simple as replacing the batteries of your thermostat. Use batteries suitable for your thermostat model and see if the problem is gone.

Clean the thermostat

A dusty thermostat can cause inaccurate temperature readings and a number of other issues with your furnace. Open the thermostat carefully and use a soft brush to get rid of dust.

Check the level

Your thermostat should be perfectly level in order to work properly. Use a level device to make sure the thermostat is completely straight.

How do you troubleshoot a furnace?

If you’ve determined that the thermostat isn’t the cause of your furnace malfunction, try these troubleshooting tips:

  • Check the furnace switch. Someone may have accidentally turned off the power switch of your furnace. Try flipping it back on to check if that’s the case.
  • Check the air filter. If you haven’t cleaned your filter in a while, it’s possible that dirt and dust build-up has engaged a safety feature that prevents the furnace from turning on. Clean the filter and see if that helps.
  • Check the pilot light. Gas furnaces have a pilot light that goes out if there is a risk of gas leaking into your home. If the light is out, reset your furnace or call HVAC professionals to determine the exact cause.
