Is a Dirty Air Filter Really That Serious of a Problem?

Before we go any further here, let us answer the question that we’ve posed in the title of this post: yes, a dirty air filter is a very serious problem. While routine air conditioning maintenance is certainly the best way in which to keep your air conditioner in fine working condition, you cannot settle for having your air filter changed just once or twice a year. Typically, an air filter will have to be changed every 1-3 months. There are too many variables to consider to give you a guarantee as to how frequently your air filter will have to be changed. What we can give you, though, is some information regarding the issues caused by clogged filters.

Increased Cooling Costs

You may think that the increased airflow resistance generated by a clogged air filter is negligible, but you’d be wrong in thinking so. When your air conditioner is constantly struggling to cool your home by forcing air through a clogged filter, you’d better believe that you’ll see that increased effort reflected in your cooling costs. Changing your air filter regularly will help to keep your air filter working as efficiently as possible.

Reduced Indoor Air Quality

Are you worried about declining indoor air quality in your home? If you’ve noticed that your air quality is plummeting, it may be due to a dirty and clogged up air filter. If the air filter is too dirty for air to pass through effectively, your system may actually force air around it. That air will not be filtered, and may distribute pollutants throughout your home.

Low Cooling Output

Your evaporator coil is a component in your HVAC system in which refrigerant is evaporated, absorbing heat in the process. If there is not enough airflow moving over this coil, though, it can ice up. When that happens, your system is not going to remove heat from the air passing through it as effectively as it normally would.
