Maintaining Your Air Conditioner

Regular maintenance on your air conditioner is important to extend its life and to get optimal and efficient performance, especially if you want to stay cool during the warm Arizona summers.

The more efficient your system is, the more you save on electric bills. These are a few tips to help you maintain your AC unit.

Clean and/or Replace Air Filters

One of the most common and most important tips for maintaining your AC unit is cleaning and replacing the air filters. You will replace the air filter, unless you have a reusable filter then you will clean it. During the summer here in Arizona, you should be changing your air filter every month or every two months. During the spring and fall, when the weather is nice outside, you will only need to replace once or every 3 months.

It’s important to remember that not only will replacing your filter maintain your AC unit, but it will keep the air cleaner. The air filters become full of dust, dirt and allergen particles, causing your system to work harder and less efficient.

Keep Coils Clean

Condenser and evaporator coils can become dirty in the process of cooling the refrigerant as dirt is absorbed and begins to build up. The buildup of dirt reduces the airflow and insulates the coil, reducing its ability to absorb heat. If your AC system begins to no longer produce cool air, your condenser coils may be your problem. It is important to keep your coil clean because they can lead to much larger issues such as an overheated compressor and causing the entire unit to shut down.

Condensate Drains

Taking the time to clean your air conditioner’s condensate drains can yield great results in the life of your AC unit. When clogged drains happen, algae and mold can grow inside which cause problems with the unit being able to reduce humidity. This can result in excess moisture in your home and could cause discoloration on your walls or carpet.

Check Wiring and Components

By checking the wiring and components on the condenser unit, you may be able to identify the cause to your air conditioning issue. Always remember to turn off the power before you start working on your unit.

Examine the Thermostat

One step that may be overlooked is checking your thermostat to make sure it’s working properly. The newer, programmable thermostats are easier to manage the cool/heat settings as well as save you money by not having your AC running all day.

Check Surrounding Area of AC Unit

Cleaning up the leaves, branches, and debris outside around your unit will ensure proper airflow to your air conditioning unit. Debris may even fall into your unit, especially during the winter months when it may not be used as often. Make sure you call a professional before you take apart your unit!
