It is springtime, and as the weather gets warmer, we should take some time to inspect our air conditioners. Air conditioners work hard to keep our homes comfortably cool during the summer, so let’s take some steps to ensure they can work correctly when the weather turns hot!
An example of dirty air conditioner coils
As our home inspectors are busy with the spring market, we see more and more air conditioners that need a good cleaning. Over time, debris and dirt accumulate in the air conditioner coils. We see this more in cases where an air conditioner condenser is very close to where a dryer vent exhausts at a home's exterior.
Dirty air conditioner coils make your air conditioner work harder and less efficiently, which wastes electricity and leads to higher utility bills. A little bit of effort on your part will help your AC system work better to keep your home cool in the summer months.
The importance of cleaning the air conditioner coils
The coils on your air conditioner condenser are vital to the proper performance of your air conditioning system. These coils perform heat transfer, which is essential for effectively cooling your home’s interior. When these coils are dirty and obstructed, airflow is restricted, and the heat transfer process is inefficient, resulting in reduced efficiency.
Dirty coils also strain the HVAC system's components, causing them to work harder and wear out sooner. This leads to higher energy usage, more frequent breakdowns, and a shorter overall life for your air conditioning system.
How often should I clean my air conditioner coils?
If you want your air conditioner to run at peak efficiency, you should clean the coils at least once a year. I recommend doing a major cleaning in the fall after the weather cools down. That way, you are ready for the summer cooling season with only minor maintenance in the spring.
You may have to clean your system more frequently if you live in an area where there is a lot of airborne dust, chaff from agriculture, trees that shed fluffy seeds (like cottonwoods), or, possibly, if the dryer vent is close to your air conditioner’s condenser coils.
Steps for cleaning your air conditioner coils
There is no one right way to clean your air conditioner coils. The method below is straightforward, so feel free to give it a try and develop a process that works best for you.
· Turn off the power on your air conditioning system. To avoid accidents and prevent electrocution, it is always best to turn off the power source for your air conditioner. There should be a disconnect tumble switch or a breaker within a few feet of your air conditioner condenser unit. You may also shut off the breaker in the electrical panel.
· Remove the outer covers on your air conditioner. Typically, screws hold the covers in place on most units. Remove the screws and covers to access the coils fully. Carefully place the parts you remove somewhere to the side so you will not lose or damage them.
· Clean the air conditioner coils and fins. Remove any loose debris and particles from the coils and fins using a soft-bristled brush and compressed air. The fins are extremely fragile and can be easily bent, so use a light touch when cleaning.
· Apply a coil cleaner solution. Cleaning solutions are available commercially, or if you want, you can make your own by combining 50% water and 50% vinegar in a spray bottle. Spray the coils and fins, allowing the solution to sit for 5 to 10 minutes. Lightly brush the debris away. Rinse the coils with water. Repeat the process on any stubborn areas, and rinse when clean.
· Allow the coils to dry. After you are satisfied that the coils are clean, let them air dry. Clean and replace the covers before replacing them.
· Turn the power back on. After everything is dry and you have reassembled any parts you removed, turn the power back on to your air conditioning system.
Summary
Cleaning your air conditioner coils is relatively easy for most people. If you are uncomfortable with this project, call an HVAC technician or your favorite handyperson.
Keeping your air conditioning coils clean is crucial for maintaining your system's efficiency and prolonging its life. In addition to cleaning your air conditioning coils, it is recommended that you have your HVAC system serviced annually. Annual service will keep your system running smoothly when needed and save you money on your utility bills.
