HVAC Troubleshooting: What is Causing My AC’s Loud Buzzing Noise?

Why Is My AC Buzzing? Loud AC buzzing noise from an AC unit indicates stress on a HVAC system, specifically an electric issue.  It is important that you do not become familiar with the noise, and instead turn off your AC unit and call a licensed HVAC contractor. It is also important to distinguish the noise from rattling or grinding, as those sounds are a typically signs of malfunctioning parts, debris or misalignment.


AC Buzzing noises are usually from electrical arcing – a discharge when electricity is jumping between circuitry. Loud buzzing noises indicate the electrical voltage flowing through your air conditioner is not at its correct amperage. Failing electrical components increases the risk of fire and should be diagnosed by a licensed HVAC expert to keep you and your home safe.


The motor needs to be lubricated with oil, especially in older AC units, to keep bearings from getting worn and eventually malfunctioning. A bent blade on the fan could also cause a buzzing noise. Lubricating the motor or replacing fan blades should be done before extensive use of AC (at the beginning of summer for example) to prevent a malfunctioning system later on.


If a buzzing or hissing noise is coming from the AC unit itself, it could be a sign of a refrigerant leak. Refrigerant leaks cause AC units often freeze up, even during the hottest time of year when the AC is consistently on. Water dripping onto the motor will cause also an abnormal noise; the repair would involve locating the obstruction/leak and properly isolating the unit.


AC Buzzing Noises This is associated more with a rattling noise, but misalignment or loose screws/panels could also create a ‘buzzing’ noise. Poor installation or aged AC parts cause screws to become loose, also causing the panels on the cabinet to unfasten.

Are Solar Panels Durable?

How Durable Are Modern Solar Panels? One of the most common questions we receive from our San Diego solar energy customers is “are solar panels durable?”

To the naked eye, solar panels appear susceptible to damage from low-impact collisions, but looks can be deceiving.

The solar cells themselves are very fragile. In fact, they are only a few millimeters thick.  However, the glass and frame that surrounds them is very sturdy and durable.

Solar panels are designed to endure even the most severe weather conditions. From 90+ mile per hour wind to medium sized tree limbs to golf ball sized (or larger) hail, solar panels have been specifically tested and designed to withstand any impacts.

Guidelines and More

A good general guideline for determining how durable a solar panel is against impact is if it will break your roof, it will break your solar panels.  If something large enough to break your roof has impacted your home, there is a good chance you have bigger things to be concerned about!

The most vulnerable part of your solar panel is actually the underbelly of the panel. This area is not designed to withstand impact, so most often when a solar panel breaks, it is due to negligence during installation. This makes it very important to ensure you choose a solar installer that treats your panels with care during installation. This becomes important if they ever need to be removed temporarily for other home improvement projects.

Solar panels are very durable. We still recommend that you contact your insurance adjuster to ensure that your solar panels are covered by your home insurance policy. Many problems—in the unlikely event they arise—will be covered by the manufacturer’s warranty. Solar panels represent a major investment in your home and it is a good idea to make sure that investment is protected as much as possible. Different manufacturers offer different levels of quality in a solar panel. Learn more here.

Can Solar Be Installed on a Tile Roof?

Efficient Solar Panels on Tile Roofs Have a tile roof and want to install solar panels, but not sure if you can? Solar panels on tile roofs are one of our specialties.

The good news is you can! Installing solar on a tile roof requires a different approach, but it is possible. On a traditional asphalt roof, solar installation would simply require drilling into the roof and attaching your mounting brackets to the roof studs. The area around the mounting brackets is then sealed and a flashing is installed to prevent water infiltration from the roof penetrations.

When installing solar panels on a tiled roof, the tiles must be removed. Attempting to drill through the tiles may result in the tile cracking and needing to be replaced—increasing your installation costs. If you have specialty or antique tile, it is a good idea to have a roofing specialist remove the tiles to prevent damage during removal.

Once the tiles are removed, the mounting brackets are put into place and flashing are installed just as they would be on a normal solar installation.

If you would prefer to leave the tiles in place, you can attempt to drill through them. If you prefer this method, remove the tile and put in a mounting bracket. Drill a hole in the tile you have removed and put a threaded rod through the hole and into the mounting device.

No matter how you install it, you will need to seal the roof penetrations and put a flashing in place to prevent leakage. Our company is highly skilled in installs on many different roof types, including tile. Looking for financing for your new solar power system? We have you covered.

Can Solar Be Installed on a Slate Roof?

Best Solar Panels on a Slate Roof Want solar panels on a slate roof, but not sure if that is possible?

Although this comes up less in the Southern California area than installing solar on a tile roof, we are still often asked whether solar panels can be installed on a slate roof.

Slate roofs can present a little more difficulty than a standard asphalt roof, but with the help of an experienced solar installer, you’ll have your home creating clean and reliable electricity quicker than you think! Our company is highly skilled in installations on any kind of roof.

How Is Solar Installed on a Slate Roof?

The installation process on a slate roof is roughly the same as it is on an asphalt roof. The major difference, however, is that instead of drilling your mounting brackets into the slate roofing, the roofing tiles must be removed. A standoff is then attached through the sheathing to the rafter below and a mounting bracket is attached to the standoff.

Once the standoff is in place, then you simply flash around the standoff in the same way you would around a roof vent or a solar array installed on an asphalt roof. The overall process is very similar to any other solar installation. It is important to keep in mind that you are dealing with roofing components that are much more fragile and expensive than a traditional asphalt roof. We recommend using a solar installation company with slate roofing experience or even having a professional slate roofer present during the installation process to ensure your slate roof is properly removed and replaced around your new solar array.

Do Nots for Solar on a Slate Roof

The only major do not for slate roofing is do not drill through the slate roofing. This can have several negative consequences. Drilling through your slate roofing tiles can make them crack—causing them to leak or void your warranty.

Air Conditioner Repair in Temecula, CA: What’s Wrong With My AC?

why did my ac stop working?

With the sizzling Califonia summer upon us, it’s paramount that you keep your AC unit in peak condition. But what if you notice your AC isn’t cooling your home as well as it used to, just before the summer months? What could be causing your AC unit to break down?   

Unfortunately, the number of people experiencing air conditioning problems often skyrockets just as the hottest months of the year are upon us. If you happen to be one of them, you’re in luck! Rely on the finest air conditioner repair in Temecula, CA to take care of any AC issues you might have and inform you about the most common causes of AC failure. Read on.  

What could be wrong with my AC?

Luckily, the majority of common AC issues can be fixed if you have your unit serviced as soon as possible. Ideally, you shouldn’t wait to have your unit checked only when you notice something’s wrong, but if you are already in this unfortunate situation, you probably want to know why your AC is not up to the task.

Dirty Filters

One of the most common reasons for reduced air conditioner efficiency are clogged filters. If you have a central AC unit, make sure to clean or replace your filters at least once a month to keep the system running smoothly. If your filters are dirty, your AC won’t be able to cool your home effectively and might cause your evaporator coil to freeze up.   

Refrigerant problems

The performance of your AC is optimal when your refrigerant charge is neither undercharged nor overcharged but is in line with the manufacturer’s specifications. If you notice your unit isn’t cooling properly, you might be low on refrigerant or you are dealing with a leak. In this case, hire a qualified technician to check your AC system’s refrigerant level and fix possible leaks.  

Clogged outside unit

If your condenser is dirty or blocked by debris or plants, your unit will have difficulty absorbing heat from the air in your home and transfering it to the outside unit. This forces your AC unit to work much harder to cool your home which puts additional strain on the system and may result in higher energy bills.    

What can cause your AC to stop working?

None of the already mentioned issues seem to be the reason your unit is malfunctioning? What else could be causing your unit to fail? Here are some additional causes of AC failure you might not have thought to check:

  • Ventilation issues: if one of your unit’s fans isn’t working properly, a likely result is poor airflow and reduced efficiency. Make sure to check your fans to avoid this relatively small issue leading to compressor failure.
  • Frozen evaporator coils: the evaporator coil is designed to absorb heat from the air. If it freezes, usually because of low refrigerant charge or dirty coils, your unit is likely to break down.  
  • Thermostat problems: if your thermostat is old, your unit might not be getting the right commands from the control system. In case of a modern programmable thermostat, your settings might be incorrect. Check the settings or replace your old thermostat to fix the issue.
  • Ductwork leaks: central AC systems have ductwork installed in the walls to transfer the cooled air throughout your home. In case these ducts are damaged, your cooled air might leak inside your walls, causing your unit to work less efficiently.

How do you fix common AC problems?

While you should refrain from fixing any AC issues yourself, you should know how to properly maintain your unit and avoid more serious problems. Here’s how you can prevent some of the most common causes of AC failure:

  • Maintain your unit regularly: the majority of less serious air conditioner issues can be prevented with proper maintenance. Have your unit serviced regularly by trained HVAC technicians.
  • Clean the outdoor unit: in order to prevent fan or evaporator coil failures, make sure to clear any leaves, trash or other kinds of debris from your outdoor unit.
  • Get a programmable thermostat: if you want to save energy and avoid older thermostat issues, buy a programmable thermostat and learn how to use it properly.
  • Have the ductwork checked: if you receive a higher than usual energy bill, have an expert check your ductwork for any holes or other signs of damage.

AC Inefficiency: Causes & Solutions

First-Rate Air Conditioning Repair in Riverside The purpose of having an air conditioner in your home is to be able to rely on it to keep you cool during the sweltering summer months. Unfortunately, it’s not a rare occurrence for air conditioners to let us down when we need them the most, taking too long to cool down the space. But why does this happen? Why are air conditioners inefficient from time to time?

There are numerous reasons why your air conditioner may not be functioning properly. While some of the common efficiency problems can be fixed by simply replacing the air filter, other, more serious issues may require expert air conditioning repair in Riverside. Either way, you should reach out to HVAC experts as soon as you suspect problems with your unit.

Read on to learn why your air conditioner is inefficient and learn what you can do about it.

How long does it take for a house to cool down with AC?

Do you feel like your AC takes too long to reach your desired temperature? If that’s the case, it doesn’t necessarily mean that something is wrong with your unit. The exact time that your AC will need to cool down your home will depend on a number of different factors, including:

  • The temperature when you turn on your cooling system
  • The size of your home
  • Whether you have insulation in your attic

For instance, a properly functioning air conditioner should be able to cool an average, four-bedroom house by 10 degrees (°F) in about three hours if the outdoor temperature isn’t extreme and your attic is insulated. If you notice that your AC is running constantly without cooling down your home to the set temperature, there may be something wrong with your unit.

Why does my AC take so long to turn on?

Have you noticed that your air conditioner takes quite a while to start cooling down your home? If that’s the case, the inefficiency may be caused by one of the following factors:

Dirty filters

Clogged or dirty filters are one of the most common causes of AC inefficiency. Luckily, this problem is quite easy to resolve, as all you have to do is clean or replace your air filter every one to three months. If you don’t want to deal with replacing the filters yourself, Action Air Conditioning, Heating and Solar’s HVAC professionals can perform the task within their regular maintenance checks.

Extreme outdoor temperature

If it’s too hot outside, your air conditioning system will likely take a bit longer to cool down your home. This doesn’t necessarily mean that something is wrong, but you should still take steps to make it easier for your AC to function during extreme weather. For instance, getting a programmable thermostat to schedule consistent cooling throughout the day can be of immense help during the hottest months of the year.

Air leaks

There’s a chance that air leaks around your home may be contributing to the inefficiency of your air conditioner. For instance, if you have any cracks around your doors and windows or pipe leaks, your AC unit will have to put in more work in order to maintain a comfortable temperature. Have your home inspected for leaks and have them sealed if you wish to stay cool.

Other underlying issues

Numerous other culprits may be to blame for your unit’s bad performance. Low refrigerant levels, blower motor and fan problems, electrical malfunctions, and dirty coils are only some of the common factors that can decrease the efficiency of your unit. The best way to determine the culprit is to reach out to professionals, so don’t wait if you suspect that something may be wrong with your AC.

What is the fastest way to cool a room with AC?

If your air conditioner is struggling to cool down the air due to extremely high outdoor temperatures despite being properly maintained and serviced, don’t worry! Here are some tips on cooling down your home as quickly as possible during the sizzling summer:

  • Cover your windows: if you want to control the heat inside your home, make sure to drape curtains over your windows during the peak heat hours of the day. This way, you will block direct sunlight and maintain a more comfortable atmosphere in your space.
  • Open the windows during the night: after sunset, outdoor temperature tends to drop lower than the temperature inside, unless the weather is extremely hot. If you wish to let the fresh air in, open your windows to create a cross-breeze.
  • Avoid using hot appliances: appliances such as the oven and clothes dryer generate substantial heat when used. Unless you absolutely have to use them, skip switching them on during hot days.
  • Minimize humidity: in addition to cooling down your home, modern air conditioners also remove humidity from the air. This helps maintain a comfortable atmosphere in your home. You can also use a dehumidifier to keep your home moisture-free.
  • Close unused rooms: if you don’t plan on using all rooms in your home, make sure to curtain them off or close the doors to trap the heat and improve your cooling efforts. Before you close off the room, consider covering the windows.
  • Use a ceiling fan: you can further cool down your home by adjusting your ceiling fan to run counter-clockwise during the summer. The fan will help distribute the chilled air around the house.

Is My Old Air Conditioner Dangerous?

Top Tier AC Installation in Riverside An old air conditioning system that hasn’t been serviced in years is bound to be less efficient than a modern state of the art model. But efficiency aside, is using an old AC actually harmful for your health? Should you use an air conditioner that has never been serviced?

In this article, you will learn why investing in a modern AC installation in Riverside to replace your old cooling unit is a much better solution than relying on a possibly hazardous system. Keep reading to learn how you can cool down your home efficiently using your AC without worrying about health risks.

What happens if AC is not used for a long time?

If you haven’t turned on your air conditioner for quite a while, you’re probably wondering if it’s safe to switch it on again. This will depend on the overall condition of your unit before you stopped using it as well as the exact duration of inactivity. For instance, if you haven’t used your AC for three or four months, you’ll probably be completely fine. Still, if you’re worried about dust or debris buildup, take the following precautions:

  • Check the compressor. If there are any weeds, dust buildup, or debris around your compressor unit, clear it before turning the AC on.
  • Have your unit serviced. You should have your AC maintained by professionals at least once or twice a year. If you haven’t had your unit inspected for a while, contact your HVAC professionals of choice before using the unit.
  • Use your AC in fan mode. You can remove dust buildup from the system by using only the fan mode on your AC for around 10 minutes before turning on the cooling mode.

Is it safe to use an old air conditioner?

If you’ve had your air conditioner for quite some time now and it’s starting to show serious signs of wear and tear, using the AC may pose numerous risks both for your health and the unit’s efficiency. Here are some of the hazards associated with using old air conditioners:

  • Bacteria growth: over time, your air conditioner can become a breeding ground for dangerous fungi, bacteria, and other potentially harmful germs. This is especially true for older units that haven’t been serviced and maintained regularly.
  • Respiratory issues: using an old AC will decrease the air quality in your home, which can be a serious threat to anyone suffering from asthma, bronchitis, and other respiratory conditions.
  • Fire hazard: your old air conditioning system probably has worn and outdated components, such as faulty fans, broken pipes, or deteriorated electrical wiring. This can lead to heat accumulation inside the unit which can be a serious fire hazard.
  • Volatile chemicals: many homes still have old air conditioners that rely on harmful chemicals to cool down your home. For instance, they tend to use ozone-depleting refrigerants that are highly damaging to the environment.
  • High energy bills: the older your air conditioner, the lower its overall efficiency. Along with the greater possibility of breakdowns and expensive repairs, using your old AC will likely result in significantly higher bills than using a newly installed unit would.

Can you get sick from an old air conditioner?

As we’ve already mentioned, there are numerous health risks associated with using old air conditioning units. In addition to causing respiratory problems and bacterial infections, an old AC can also cause something known as the “sick building syndrome”. You may have experienced this phenomenon if you’ve ever entered a building and quickly started to feel sick for no apparent reason.

This syndrome is a result of microorganism buildup in old air conditioners. Some individuals are more likely to notice and experience the effects of the sick building syndrome, particularly if they have any pre-existing health conditions. These effects include headaches, respiratory issues, nasal congestion, fatigue, and skin irritation.

What happens if AC is not serviced?

An aged air conditioner that has never been serviced is a recipe for disaster. And even if your air conditioner is not that old, you should still schedule routine servicing and maintenance checks. Here’s why it’s important to have your unit professionally serviced:

Dust accumulation

A dusty and dirty air filter will have a much harder time performing its primary function. Unable to filter and clean the air in your space efficiently, your AC will have to put in extra effort into cooling down your home, resulting in increased energy costs. You should have your filters replaced at least once in three months, or more often than that if your unit is older.

Less efficient cooling

Numerous components of your air conditioner, such as the electric coils and fans, need to be properly lubricated if they are to move smoothly and cool down the air efficiently. As most homeowners don’t have the knowledge and tools necessary to service and maintain these components, it’s generally advisable to have the unit inspected by professionals.

Higher possibility of breakdowns

Preventive maintenance and service is the best way to ward off AC malfunctions. In fact, most common air conditioning issues can be prevented with regular maintenance performed by knowledgeable HVAC experts. If you wish to avoid expensive repairs, you should also make sure to be on the lookout for any warning signs.

Eliminate risks with reliable AC installation in Riverside

Air Conditioners & Water Leaks: All You Need to Know

The Foremost Air Conditioner Repair in Murrieta, CA It’s a sizzling day outside and you’ve decided to try and cool down by turning your dependable air conditioner on only to encounter an unpleasant surprise: water is leaking from your AC unit inside your home. What should you do?

Luckily, there are professionals for air conditioner repair in Murrieta, CA who can help you with all your cooling struggles all year round. Even something like your AC blowing warm air or a sudden water leak from your unit won’t be as inconvenient and frustrating if you depend on the right experts in your area.

In this article, you will learn why air conditioners sometimes leak water and what you can do if this has happened to you. Read on.

Why is water leaking from AC?

If your air conditioner is leaking, make sure to protect yourself and your family from harm by turning off the thermostat and clean up the leaked water to prevent any further damage. Once that’s out of the way, you should try to determine the reason why your AC is leaking. Here are the most common culprits:

Your condensate drain line is clogged

Possibly the most frequently encountered cause of water leaks, a drain line that is dirty or clogged can cause the water to back up into your house. If this is the case, the drain line will have to be unclogged using a wet-dry vac, or better yet, reaching out to professionals who will unblock the line using specialized equipment.

Your drain pan is damaged

If your air conditioner is older (over 12 years), you may be dealing with a rusted or damaged drain pan which enables the water to seep through. If this is true, you’ll have to have the pan replaced.

Your condensate pump is broken

Air conditioners that are installed in basements typically have condensate pumps that serve to get the water outside. These pumps may occasionally break, forcing the water to stay inside and leak out.

Your evaporator coil is frozen

The evaporator coil of your air conditioner can freeze for two main reasons: clogged air filters and refrigerant leaks. The former option is more favorable, as you’ll be able to fix the issue simply by replacing the filter. The latter reason, however, is slightly more challenging as you will have to have professionals look at your unit in order to evaluate and fix any possible refrigerant leaks.

Is AC leaking water dangerous?

Favorite Air Conditioner Repair in Murrieta

A water leak from your air conditioner doesn’t have to be a cause for concern, especially if you act promptly as soon as you notice the issue. If there is a lot of water leaking, be sure to turn off the unit immediately and call your HVAC professionals of choice. This way, you will keep both yourself and your family safe, as well as prevent water damage to your property.

However, it is important to note here that water leaks and refrigerant leaks aren’t always easily differentiated. Since refrigerant leaks can be very dangerous, it is essential that you reach out to reliable technicians as soon as you suspect that something might be up with your AC.

What to do if your AC is leaking?

In most cases, seeking professional help is the best course of action to take if you notice that your air conditioner is leaking. While there are some instances where leaks happen due to high humidity levels or an extreme temperature difference indoors and outdoors, most causes of water leaks would be fixed best by qualified and knowledgeable experts.

How do you fix a leaking air conditioner?

The right approach to fixing a leaking air conditioner will depend on the specific culprit. Here is a rundown of the most common water leak causes and their solutions:

  • Frozen coils: if you notice ice on your evaporator coils, check the filter first. If it is dusty, dirty, or clogged, replace it and see if the issue persists. If it does, call a professional as you may be dealing with a refrigerant leak. Even if your AC isn’t leaking, you should replace your air filter at least once every three months.
  • Damaged drain pan: this component is located beneath the evaporator coil and serves to catch condensation and moisture your AC creates. If your unit is old, turn it off and inspect the pan for damage and leaks. If you notice that the drain pan is overflowing, call your HVAC contractors of choice.
  • Clogged drain line: typically, your AC will have a PVC pipe located near the drain pan. If this pipe is clogged, you can try pouring a little bit of vinegar (around 6 ounces) down the line every couple of months to combat potential fungi buildup. While you could try to use a wet-dry vac to unclog the line yourself, it’s safer to rely on experts.

No matter what the exact cause may be, you should never ignore any water leaks from your air conditioner if you wish to stay safe and ensure a long lifespan of your unit. As many of the water leak culprits occur as a result of improper or nonexistent maintenance, you can prevent any similar issues from happening again by scheduling regular maintenance checkups and tune-ups.

Air Conditioner Problems: Blowing Hot Air

Expert Air Conditioning Repair in Murrieta, CA

Once the summer months draw nearer, our air conditioners once again become the devices we rely on to keep us nice and cool during the hot weather. But what happens when your AC keeps blowing warm air instead of cooling down your home? What do you do when your trusted air conditioner no longer fulfills its primary purpose?

The best way to ensure the proper performance of your AC unit is to have reliable experts for air conditioning repair in Murrieta, CA at your beck and call. This way, you won’t have to worry about unexpected breakdowns and faults just before the summer season.

In this article, air conditioning experts tackle one of the most common HVAC issues – blowing hot instead of cool air. There’s no denying that hot air coming from your AC unit is not only inconvenient but it’s also extremely frustrating, especially during the summer months. Read on to find out why that happens and what you can do to fix the problem.

Why air conditioners experience cooling issues

There are numerous reasons why your air conditioner may be experiencing performance problems, from old age and lack of maintenance to refrigerant leaks and compressor problems. In many situations, it’s not entirely clear what the exact culprit is. That’s why it’s always better to rely on professionals to inspect your unit unless you wish to risk more severe issues down the line.

While reaching to professionals is nearly always advisable, it is possible that your air conditioner is not blowing cold air because you haven’t set the thermostat correctly. If that’s the case, you will be able to enjoy your fresh and cool home in no time, as all you’ll have to do is switch the setting from “heat” to “cool”.

What is wrong when an air conditioner blows hot air?

If you’ve determined that the thermostat setting isn’t the culprit, you will have to dig a little bit deeper. While your AC blowing warm air may not necessarily indicate a severe problem, it is definitely better to tackle the issue promptly to avoid any complications. Here’s what typically causes an air conditioner to blow out hot air:

General lack of maintenance

Just like any other device, your air conditioner needs to be regularly serviced and maintained in order to work optimally. Unless you make the effort to have your AC unit inspected, you will be very likely to experience occasional faults and malfunctions.

Many HVAC companies offer annual tune-ups and maintenance checkups that include everything your unit may need to stay in top shape for as long as possible. If you want to make sure your air conditioner is optimally efficient, investing in recurring HVAC maintenance is the only surefire way to achieve that.

Dirty air filters

If you want to ensure the proper performance of your air conditioner, you need to replace your air filters at least once every three months. The filter is designed to protect the interior components of your air conditioner from dirt, dust, and debris and maximize its lifespan. If you live in a warmer climate, you should check and replace your filters even more frequently, preferably once a month.

Clogged or dirty outdoor unit

Similarly, your condenser unit also requires regular cleaning and maintenance. While you can remove any visible debris that may be blocking the outdoor unit or interfering with its moving parts on your own, it is definitely better to have experts inspect and clean it as part of your general maintenance plan.

Refrigerant leaks

Refrigerant may also be the reason why your AC is blowing warm air. If you suspect that this may be the case, reach out to professionals immediately. Refrigerant, or freon, can’t get used up, and the only way for this to happen is if there is a leak. As inhaling refrigerant can be extremely dangerous, make sure to contact HVAC experts as soon as possible.

How do I fix my AC blowing warm air?

Just as there are different culprits for blowing hot air, there are also several different solutions that may help you get your unit back into shape. As we’ve already mentioned, you should always check the thermostat first to make sure that the settings are correct. If not, try:

  • Cleaning dust, dirt, & debris from your unit and replacing the air filter if needed
  • Checking out the air ducts and to look for leaks
  • Checking the circuit breaker box and fixing any blown fuses
  • Removing any branches, leaves, or other debris that may be blocking the condenser

If none of the above-mentioned tips work, your best course of action would be to call the professionals. What’s more, relying on HVAC experts for maintenance and service throughout the year is the best way to prevent such issues from happening in the first place.

Blowing warm air is only one of the numerous warning signs that may indicate that your air conditioner may need repair. Unless you don’t mind risking more severe problems and expensive repairs, make sure to act promptly as soon as you start suspecting that something might be wrong with your unit.
