5 Common Problems With Split Air Conditioners

The purpose of an air conditioner is to keep your indoors cool and comfortable, especially during the scorching summers of Washington. There are four key things you should expect from your AC:

  • It keeps your indoors cool and comfortable.
  • It provides good air quality indoors.
  • It operates quietly.
  • It is energy efficient.

If your AC isn’t giving you all of these, you can be sure there is an issue with it. Let’s look at some common problems that can decrease the efficiency levels of your AC unit and how these can be resolved.

Common Problems With Split Air Conditioners

Clogged Air Filters

The function of the air filters is to keep the airflow free from dust and other pollutants such as pet hair, dander, and fungal spores. If your AC isn’t blowing cool air, it could be because the air filters have become clogged.

Air filters must be cleaned at least once every two months and replaced every year or two to ensure proper airflow. Neglecting to take action may eventually lead to the breakdown of your system. A professional HVAC contractor can do the job for you if you need an AC replacement in Battle Ground, WA.

Frozen Refrigerant Coils

When your air conditioner’s air filters are clogged, ice builds up in the refrigerant coils and obstructs airflow. When dirt accumulates on the coils, warm air does not reach the refrigerant. This makes the refrigerant too cold, and the moisture on the coils freezes. You can either switch off your AC and let the ice thaw completely or run the AC on fan mode, allowing the blower to melt the ice.

Thermostat Glitches

If the batteries in your AC’s thermostat are drained or dirty, or if there is a wiring issue, your air conditioner will not work efficiently. The location of the thermostat can affect your air conditioning. The inner and outer part of the thermostat needs to be cleaned. The thermostat will not function properly if it is placed near open windows or where there is a draft.

Loud Noises

If your AC makes a loud noise that sounds like a hum or click, it signals a problem. It could be an issue with the fan or capacitor, a refrigerant leak, or problems with the motor or compressor. This needs to be checked immediately before the issue becomes worse. Tuning up your AC every year will ensure it runs quietly.

Leaky Ducts

If there are cracks or holes in your AC ducts, the conditioned air will leak through, causing uneven cooling of your home. Your AC will have to work harder to cool your home, requiring more energy to run and higher energy bills. It is best to bring in an HVAC specialist to identify these leaks and seal them for you.
