One of the easiest ways to take care of your air conditioning system is by changing out the air filter on a regular basis. Preventing your air filter from getting clogged up is as easy as checking the quality of the air conditioner at least once a month and changing or cleaning the filter when it is dirty. Failing to clean the air filter and keep things clean can have serious consequences on your HVAC system that will require you to call in a repair person to fix your air conditioner.

Issue #1: Poor Air Quality

The filter on your air conditioner is designed to remove all the dust and particles that flow through the air. The filter helps remove these particles from the air and keeps those particles from being pushed through your air conditioning system.

If you don't change out the air filter on a regular basis, the quality of your air is going to suffer. You are going to experience more dirt and allergens in the air. You may have to bring someone in to test the air quality in your home and figure out how to improve the air quality. In truth, all you need to do is change the filter.

Issue #2: Frozen Air Conditioner

A clogged and dirty air filter can cause your air conditioner to completely freeze up. When the air filter is clogged, the amount of air that flows through the system is reduced. This reduces the air that circulates around the coils in your air conditioning unit. The air that moves around the coils is important, as it helps remove condensation generated by the refrigerant that flows through the coils and keeps them cool.

When not enough air is circulating around the coils, that condensation builds up and can freeze, causing ice to cover your air conditioning unit. If your unit is frozen, call in a repair technician who will make sure the ice didn't damage the unit and who will change out the filter.

Issue #3: Short Cycling

Short cycling is when your air conditioner only runs for a few minutes, shuts off, and then turns back on a few minutes later. When your air conditioner turns off and on constantly, this puts a lot of strain on your air conditioner. This strain can cause multiple different components of your air conditioner to fail and malfunction.

As soon as you notice that your air conditioner is short cycling, you need to call in a repair technician. At this point, simply changing the air filter may not be enough. The clogged air filter may have caused additional damage that a technician will be able to find and fix.

Issue #4: Flipped Limit Switch

Inside of your air conditioning system is a limit switch. The limit switch is basically like an emergency back-up system that stops your air conditioner from operating under dangerous circumstances.

A clogged air filter can cause a host of dangerous issues, such as an overheating system, that will engage the limit switch. If your unit will not turn on, you need to call a technician to find out what engaged the limit switch, fix the issue, and disengage the limit switch.

It is important to change out the air filter on a regular basis. If you don't change out the air filter, a host of more complicated issues can occur.
