How Does Failure to Change the Air Filter Affect the AC?

If you have been using a central air conditioning system for any amount of time, then you are hopefully well aware of just how vital it is that you change the air filter therein regularly. Typically, an air filter is going to have to be changed every 2-3 months, though certain systems in certain homes, using certain filters, may require monthly changes. As you can see, there is no set rule as to just how frequently any given filter will have to be replaced. What is true across the board, though, is the fact that a dirty, clogged air filter is going to seriously impede the performance of your air conditioning system in Tucson, AZ.

It restricts airflow…

When your air filter is clogged up with dust and dirt, it is going to make it harder for the air conditioner to force air through that filter. This can lead to issues with indoor air quality, as conditioned air can actually be forced to bypass the filter, and the pollutants therein will wind up in your living space. Of course, it is also going to directly affect your comfort, as well.

…which impedes the cooling process…

Your air conditioner does not generate cooled air. Instead, it draws heat out of the air already in your home. Warm air passes over the evaporator coil, where refrigerant evaporates and absorbs heat. If there is not enough airflow over the evaporator coil, the component can actually ice over. This further inhibits the system’s ability to cool your home successfully.

…and drives up cooling costs.

Not only will your home likely be less comfortable, but you may also wind up paying more for a weaker performance from your home cooling system. Your AC is going to work overtime as it attempts to make up for lost ground, and it will burn through energy in doing so. You’ll see that reflected in your utility bills.

Remember to change your filter, and to work with the AC pros here at Goettl Air Conditioning.
