Protecting Your AC From the Weather: What You Need to Know

blank Although ACs are hardly used in the winter, it doesn’t imply homeowners can afford to delay a routine AC service until Spring. Winter brings increased precipitation as the temperature plummets, making your AC unit prone to various forms of damage. This means that homeowners should keep a watchful eye on their units even more so than in the summer heat.

To learn more about the harmful impact of the elements on your unit and find out how to prevent expensive AC repairs further down the line, read on. With a few simple expert tips, you will be able to extend the life of your device. If you’re a resident of Murrieta, near Wildomar or Lake Elsinore, you have access to the services of dependable HVAC contractors like Action Air.

Can Rain Damage my AC unit?

Typically, rain is unlikely to significantly harm your AC unit. An air conditioner’s key components are housed in a well-sealed metal casing, which is difficult for rain to penetrate. However, water could promote the growth of mold or the spread of rust if you leave your AC uncovered.

While light rain isn’t usually a reason to worry, if there’s very heavy rainfall, producing more than 15 inches of water, you’ll most probably have cause for concern. If an AC sits in deep stagnant water, the chances are the moisture will cause havoc.

In case your AC has had prolonged exposure to deep standing water, wait for it to dry before doing anything else. Do not turn it on. Your first move should be to contact qualified HVAC professionals for a comprehensive AC service. Certified technicians will assess the extent of the damage and suggest and implement the best solution in the situation.

What is more, if there was a rainstorm, you should also keep an eye out for potential wind damage. For example, twigs and other debris carried by the wind may get jammed in the fan blower, creating issues.

Should you cover the air conditioner in winter?

Your outdoor air conditioning unit is at the mercy of the cold, the rain, and other weather conditions. Strong winds can lead to the accumulation of debris that could impair the functioning of your air con. Also, in certain cases water could seep into the unit and freeze inside, and cause a fault with your condenser fins. Icicles could also fall and hit your unit from above, giving you yet another reason to worry.

Thankfully, you can reduce your exterior unit’s exposure to the elements in a very simple way,   by providing a cover for it during the winter. Here are some ideas for you to try out:

  • Use covers made from breathable materials only. Although effective at protecting your unit from dirt and debris, plastic covers won’t allow the moisture to evaporate. This may lead to the development of corrosion or mold. This type of cover can also become a safe haven for bugs, causing them to inhabit your AC. Your cover shouldn’t be placed around the unit tightly. Instead, leave it some breathing room.
  • You could put a piece of plywood on top of the AC. Put rocks or bricks over it or tie it with a rope to hold it in place. The plywood surface will prevent leaves and ice from getting in touch with the device by providing a barrier.
  • Try building a protective awning for the unit. It can be easier than you might expect, so the chances are you could carry it out even if you aren’t an experienced DIY enthusiast. This way, you will shield the unit quite effectively.
  • Planting shrubbery around the AC can make for an added layer of protection. Neither wind nor rain will reach the unit so easily if there’s a physical barrier that is keeping it sheltered.

If you have any questions about the maintenance and protection of your air conditioner, feel free to contact a reputable team of HVAC experts. When it comes to such an essential part of your home, it’s better to be safe than sorry. HVAC technicians will inspect your unit to check for any signs of trouble and suggest a suitable repair or maintenance option. Professionals can also clean your furnace before winter, tell you what the typical lifespan of a furnace is, and solve other dilemmas.

When is the best time to test an air conditioner?

Note that you shouldn’t wait for the weather to get too hot before turning on your air conditioner. But, refrain from testing your AC while it’s freezing outside as well. Experts recommend testing your air conditioner when the outside temperature has been above 60 degrees for two days.

Essentially, you should test your AC while it’s still not too cold or too warm outside to enable it to get back into gear more gradually. What’s more, you will be able to catch any issues with your unit before the heating season starts and it gets more difficult to schedule an AC service repair.

How do an AC service after winter?

In order to fully prepare your air conditioner for the Spring and Summer, both the indoor and the outdoor units of your system will require attention.

INDOOR UNIT

Before you turn on your AC, you should take some time to address any indoor unit concerns. Prepare the your unit with these at-home AC service procedures:

  • Clean the vents: if your AC has been inactive for months, there is a great chance that dust and dirt have accumulated inside the vents. This can decrease your indoor air quality, as it can circulate airborne contaminants throughout your home. Make sure to check and clean the vents to remove any dirt and dust that may have settled there.
  • Inspect the ductworkductwork inefficiencies can cause homes throughout the U.S. to lose up to 30 percent of energy. This is why it’s important to inspect and seal your ductwork before the cooling season begins. Look for signs of damage in your ductwork, especially in crawl spaces, attic, and basement, and hire HVAC technicians to handle any issues.
  • Change the filter: before you turn your unit on, make sure to check and replace your filter. AC filters can quickly get clogged with dust and dirt, especially after months of inactivity, which can contribute to lower efficiency, malfunctions, or breakdowns.
  • Inspect your thermostat: is your thermostat old or inefficient? If so, consider purchasing a new programmable thermostat before the spring season to maximize efficiency and ensure even cooling throughout your home.

OUTDOOR UNIT

The outdoor components of your air conditioning system also need to be inspected or given an AC service before use during the spring. This can optimize airflow and make sure that the condenser unit is in tip-top shape after months of inactivity. Take the following steps:

  • Remove AC covers: many homeowners choose to cover their outdoor condenser units during the winter months. While this is not recommended for a number of reasons, it is important to remove any covers before using the system for the first time. Running your AC with a cover on may cause a variety of problems fairly quickly.
  • Inspect for damage: before turning on the system, check the unit’s outdoor panels and electrical connections for damage. If you notice that any panels are missing or misaligned, make sure to contact HVAC experts to prevent safety risks. Also, make sure to check out the AC line set running from the outdoor unit to your home, as the insulated sleeve wrapping them can sustain cracks, fraying, and other forms of damage.
  • Remove debris: it is important to clear away any twigs, leaves, and dirt that may have accumulated along the outdoor unit, as debris can restrict airflow and lower your system’s efficiency.

How preventive AC service & maintenance helps

The best way to ensure optimal performance of your unit and prevent expensive breakdowns in the summer is to schedule an AC service tune-up. Here’s how it can help:

  • Regular maintenance boosts the efficiency of your unit which can bring you great energy savings.
  • Preventive maintenance can also minimize the risk of unexpected breakdowns and expensive repairs.
  • Routine maintenance can extend your AC’s lifespan, maximizing its value.
  • Not sticking to a routine maintenance schedule can void your warranty and cause you to pay out of pocket for any repairs.

How to Reduce Your Heating & Cooling Costs With summer now in full swing, your HVAC system will be doing a lot of work to keep your home cool. Our team at Action Air has put together this simple guide to make sure you are saving on utility costs, without compromising your home’s comfort.
Energy Star found that nearly half of your home’s energy is used for heating ad cooling. Here are 10 tips to keep your home cool this summer without over-running your HVAC system:

Paint Your Roof

According to a study conducted by Heating Island Group at Berkley Lab, homes with black roofs require up to 40% more energy to cool a home. Although it may seem like a heavy-duty task, painting your roof can be simple, cheap, and has the additional benefits of increasing your roof’s life span and water resistance. You can purchase an inexpensive white elastomeric coating and heavy duty paint rollers at most hardware stores. Apply 2-3 coats on your roof for best results.

Upgrade Your AC System

Installing an energy efficient AC system in your home is the best long-term solution to keep energy costs low while adding value and efficiency to your home. The investment of a new AC system can save you big in the long run; an outdated HVAC system will lead to costly repairs, expensive utility bills, decreased home comfort, and poor indoor air quality. Request that your new AC system is installed in the shade – an AC unit in direct sunlight will use more energy. Action Air Buyer’s Guide for New AC System. will give you all the tools to make sure you are getting the best product for the best price.

Change Your Air Filter Regularly

Changing your HVAC’s air filter is the most important self-maintenance you can do to save on utility bills, keep your HVAC system running smoothly, extend the lifespan of your cooling/heating system, and keep your home’s air quality healthy.

Switch to Solar

You can cut your utility bills down as much as 50% by switching to solar PV panels. Not only does solar powered energy save you huge on utility costs, it enables homeowners to become independent from utility companies, adds value to your home, and is a renewable source of energy that helps save the environment. The benefits of switching to solar are endless. Now is the time to make the switch with all the current financing options, state rebates, and federal tax incentives available.

Clean Around Your AC Unit

Make sure your AC unit is not being suffocated by debris or leaves. Blockages to the AC compressor and restrict airflow and make your AC work twice as hard. It will also help keep your increase your indoor air quality and help keep those AC filters clean.

Install Ceiling Fans

Although ceiling fans won’t solely keep your home comfortable in the midst of the summer heat, they help circulate cool air throughout your home and also enables the homeowner to turn off the AC during the cooler parts of the day or at night. Installing a fan in your attic will help prevent the hot, stuffy air from leaking into the rest of your home and reduce cooling costs.

Control Your Thermostat

Being conscience of how often your AC is running is a key component in keeping your cooling costs low. Smart thermostats are the most convenient way to control the temperature in your home that is conducive to your lifestyle. All you need to do is enter settings based on the season, your schedule, and preferred temperature. The Smart Thermostat does the rest. With Smart Thermostats and an Energy Efficient AC unit, you can you keep your home comfortable at the lowest price.

Run Your Appliances While temperatures are Cool

Your dishwasher, clothes dryer and stove add extra heat to the house. If you run these appliances during the day when temperatures are cooler, in the morning or evening, it will prevent your AC from working harder.

Seal Air Duct Leaks

Air duct sealing will eliminate this air loss and the corresponding energy loss – lowering your energy consumption and your power bills. If you are upgrading your HVAC system, having your ducts sealed first may allow you to install a smaller system, increasing your savings.

Schedule a Routine Maintenance Appointment

How to Cut Down on Energy Costs with HVAC Maintenance Regular maintenance on your HVAC system will can significantly reduce your heating and cooling costs. When your AC unit is running at optimal performance, it will not have to work as hard – or long – to cool your home. Regular maintenance will also improve your home’s indoor air quality, and mitigate expensive repairs.

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.

Electrical

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.

Motor

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.

Refrigerant

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.

Parts

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.

HVAC Troubleshooting: Why is My AC Rattling?

When you hear your AC rattling, it is a good indicator that something has gone awry with your HVAC system. Ignoring the issue will create expensive repairs, so make sure you schedule a maintenance, tune up, or repair appointment with a licensed HVAC contractor. There are several situations that could cause a rattling noise – it could be an easy fix such as tightening screws, or it can be an indicator of malfunctioning parts which can become very expensive if gone unrepaired.

Debris

When the filter has not been changed for a while and becomes clogged, dirt, sticks, leaves, gravel and other types of debris can enter the AC cabinet and get knocked around. A dirty AC filter can cause serious damage to the AC’s parts/components along with a variety of other issues, and should be fixed immediately to prevent any more debris from entering.

Panels

Poor installation or aged AC parts can cause screws to become loose, which cause the panels on the cabinet to unfasten. This is common with old HVAC systems, which should be maintained at least twice a year.

Fan

Rattling caused by the fan within the AC unit could be from the blades themselves can becoming loose, especially in older AC models. Luckily, fan blades are easily replaceable. If the fan is misaligned due to debris or age, it will progressively get worse and eventually cause the fan to stop functioning. Dirty blades can also cause noise, so it is important to keep the blades clean and make sure your AC filter is changed regularly.

Motor

The compressor is the ‘heart’ of HVAC system, and when its parts become loose it can cause a total system breakdown. This is more common with older HVAC systems. When the noise increases from the compressor, it is usually a strong sign the compressor’s hardware needs replacing.

Installation

An unstable AC unit is a common source of rattling noise. Improper installation can cause parts to be more susceptible to damage. The noise could be from the damaged parts or by the AC unit or the platform not lining up with a window sill. Re-installation can easily fix the rattling if you notice loose/shifty parts.

Preventative maintenance can fend off unwanted repair bills and inconvenient HVAC malfunctioning during the months you use it the most. Call us today to learn more about our Precision Tune Up Program or to schedule an appointment for repair with one of our NATE-certified technicians!

Troubleshoot Your HVAC

Troubleshooting your HVAC system can save you on maintenance and repair costs, but it’s important to know the ABC’s of HVAC systems to safely and efficiently evaluate it. Your home HVAC system typically includes both central heating and central cooling which are two separate systems that share ductwork.

Commonly, the central cooling system includes a cabinet outdoors that contains a condenser coil and compressor and an indoor evaporator coil that is usually installed with your furnace or air handler. The compressor is the piece of equipment that moves refrigerant through the system.

The cooling part of the HVAC systems works by moving warm air across the indoor evaporator coil which transfers heat from the air to the refrigerant to cool the air. The refrigerant is cycled back to the compressor to repeat the job and the cool air is blown inside your home. The heat transferred to the refrigerant is removed to outside the home.

The heating system has a primary heating appliance which is usually installed in your garage or basement. A furnace is one type of heating appliance and it can run on either gas or oil, or on a hybrid system, depending on your region and needs. The furnace generates combustion gases that are passed through a heat exchanger. Air from your home is blown across the heat exchanger, which warms the air to be transferred through the ductwork and distributed back into your home. You should be especially careful when troubleshooting old furnaces considering the outdated parts, and hazards of CO2 and fires.

Most often, HVAC issues are related to one specific part of the system, such as the duct system, heat pump, or vents, to name a few – which makes troubleshooting a relatively methodical task. Start by inspecting the visible equipment and work towards the less conspicuous parts.

The first step of your diagnosis should be to confirm that your system has power. The furnace and air-conditioner will have separate fuses or circuit breakers. The thermostat will also have its own power source, either electrical or battery powered.

If cold air is blowing from your heater, there are a couple things you can troubleshoot to identify the issue. First, check the thermostat to see that it is set to “auto” instead of “on.” If it is set to “on,” the fan will blow continuously even if the furnace isn’t heating the air, causing the air coming out of the vents to feel cool. Next, check your air filter and change it if it is dirty. A dirty filter can restrict airflow and cause other equipment to malfunction.

Other causes of HVAC failures can include an outdated HVAC system/parts, poor drainage, frozen coil, a pilot light or ignition problem, inadequate fuel supply, large leaks in your ductwork, or a clog in your condenser. These type of issues are best identified by calling your local certified HVAC professional.

If troubleshooting your HVAC system doesn’t solve the issue, call the fully Nate certified staff at Action Air Conditioning, Heating and Solar today to schedule a maintenance and repair appointment to get your system working at optimal performance!

Avoid a Frozen Air Conditioner This Summer

This may seem like an oxymoron – a frozen air conditioner unit in the midst of summer – but it is actually a very common problem for homeowners. Our team at Action Air Conditioning knows how quickly a frozen AC system can make a nice summer day go awry, so here is all the information you need to prevent, troubleshoot, and repair a frozen air conditioner.

How do I know if my Air Conditioner is frozen?”

The first sign is leaking water around vents or the Air Conditioning unit. Check the registers inside your home while the AC is on. If the vents are blowing out warm air, it could very well be a frozen Air Conditioner. Locate the evaporator coil on your HVAC (typically near the furnace system inside the home) and open the access panel. Small hex-head screws should be holding the panel in place. You will be able to see the ice formed around the coil, or even outside the Air Conditioning unit in severe cases.

What should I do when I notice my Air Conditioner is frozen?”

Turn off your Air Conditioning completely and call a licensed HVAC contractor. This will allow the unit to de-thaw until an HVAC technician comes to the rescue. Don’t try to scrape off the ice by hand as this could cause even more damage to the Air Conditioning unit resulting in an expensive repair. Also check to see if the air filter is dirty as it could be the culprit to your frozen Air Conditioning. Even if the air filter is dirty and replaced, you should still get a licensed HVAC contractor to examine the unit for any other issues that contributed or caused the problem.near the furnace system inside the home) and open the access panel. Small hex-head screws should be holding the panel in place. You will be able to see the ice formed around the coil, or even outside the Air Conditioning unit in severe cases.

What causes a frozen Air Conditioner?

There are two main causes of a frozen Air Conditioner: restricted air flow or a lack of refrigerant. Without proper airflow to the evaporator coil, the condensation will freeze before it gets a chance to be drained from the unit. Restricted air flow could be caused by a dirty air filter, faulty fan, closed registers, or drainage issues. Refrigerant is necessary to prevent the evaporator coil from freezing. If the refrigerant is low, it could be the source of the problem and would require a licensed HVAC technician.

What can I do to prevent my Air Conditioner from freezing?

Performing regular maintenance on your HVAC is the best way to prevent AC malfunction and expensive repairs. We recommend an AC Tune Up twice a year for newer models, or 4 times a year for older HVAC systems.

Keep up with your air filter. A dirty air filter can not only cause a frozen AC, but poor indoor air quality, expensive utility bills, and put unnecessary wear and tear on your HVAC system.

How to Prevent HVAC Emergencies

Preventative maintenance is the the best way to protect your home, family, or business from inconvenient HVAC breakdowns. 90% of all HVAC system failures are due to a lack of maintenance. Performing regular maintenance by a certified HVAC contractor will also save you from expensive repairs down the road, keep your home safe and hazard-free, improve your indoor air quality, and save you on energy bills.
Replacing an outdated HVAC system is worth the initial investment. Aging heating and cooling systems have to work harder to keep your home comfortable – resulting in system malfunction and increased energy bills.
Reliable, NATE certified technicians make the difference between quality repairs and improper service. Inexperienced technicians can misdiagnose or perform improper service that will result in more expensive repairs, or even worse, put your HVAC at risk for total system breakdown.

HVAC Troubleshooting: Pooling Water Under Air Conditioning

If you notice a pool of water under your AC, it is a sign that your HVAC needs to be repaired or replaced. There are several things that can cause this common AC issue, so it’s important to call a certified HVAC technician to diagnose and repair the problem. 

Water is naturally created by the AC unit from the process of pulling in the hot/humid air from outside and cooling it through the unit’s cold evaporator coil. Condensation forms and that water is expelled by the drain line into your plumbing, condensation pump, or outside. If there is any issue with the parts that control this process, a pool of water will form under your AC unit. In this case, your AC is not running efficiently and could cause more expensive repairs, premature damage to parts and increased energy bills. Here are a few common causes for pooling water under AC:

  • Condensation pump – When the water is not expelled properly due to a faulty condensation pump, the continual presence of water in an AC unit will create mold and mildew build up and cause the system to clog. This is important to repair in a timely manner to prevent a snowball-effect of other problems because of a clogged unit.
  • Blocked drain hole – If condensation/water is not able to exit the unit due to a clogged drain hole, the water will have nowhere else to go but inside your home or pool around the unit. A clogged drain hole is caused by dirt, insects, debris or mold/mildew build up inside the unit. It could also be from a dirty evaporator coil in which case the dirt will mix with the water and fall down into the drainage pan, clogging the drain hole.
  • Frozen evaporator coil – Low refrigerant causes the coil to become much colder than necessary, in turn freezing it. A dirty air filter will also cause the coil to freeze from the lack of airflow. To defrost the coil, turn your AC off and call a licensed HVAC contractor to correct the problem.
  • Bad sealing – If the seals on your AC unit are not tight, it will cause an excess of air inside. The moisture from that air will build up when the warm air meets the cold air inside the AC unit. A HVAC contractor will need to reseal the outside of the AC to keep it properly isolated.
  • Poor installation – This is common with newly installed AC units. The problem of pooling water happens when condensate trap is not installed correctly, which will prevent the water/condensation from properly draining.

Action Air is dedicated to your home’s comfort and energy savings. If you are experiencing pooling water under your AC, call Action Air to schedule an appointment with one of our Nate-Certified technicians.
