How Might a Clogged Air Filter Affect My AC?

Now that we are making our way steadily into the hottest time of the year, routine air conditioning maintenance is at the forefront of many homeowners’ minds. While it’s, of course, important that you schedule professional air conditioning maintenance in Darien, CT, there is one task that falls squarely on your shoulders to complete. That is ensuring that your air filter is changed as recommended and as needed. While your AC technician will replace your filter during a maintenance session, once or twice a year just isn’t going to cut it. Read on to learn more about why this simple procedure is so important.

Protect AC Efficiency and Performance Quality

When your air filter is clogged up with dust, dirt, and other debris, it is going to increase the airflow resistance faced by your home cooling system. This is detrimental for a few different reasons.

  1. First of all, increased airflow resistance is going to result in increased energy costs, as your system will work harder than it should have to in order to force air through that filter and into the air distribution system, or ductwork.
  2. When there is too much resistance in the filter due to clogs, your indoor air quality can suffer as well. Air may find a path of less resistance, being forced through gaps surrounding the air filter, for instance. This can lead to the distribution of pollutants throughout your home that would otherwise have been filtered out by a clean air filter.
  3. Finally, remember that your evaporator coil draws heat out of the air running over it. That is how your AC cools your home. If there is not enough air moving over the coil, icing can occur. This greatly impedes the operation of the air conditioner, and may leave you with a compromised system.
