What Happens When Your Air Filter Is Clogged?

Did you know that clogged air filters can be one of the main causes of heating and cooling system problems?

Your home air filter is restricted when dust, dander, hair and debris cover the filter element. Similar to changing your car’s engine oil, a clean A/C filter helps your A/C system from becoming inefficient and possibly breaking.

How an A/C System Works

There are several components to an HVAC system. The largest component is the outdoor unit. There is also an indoor unit, where the cooling cools and blower are located. You will also find the filter located on the indoor unit, as well. Another main component of an HVAC system is the ductwork.

These are the lines that bring the conditioned air to each room of your home. Usually, the ductwork will be either under the home or in the attic, keeping the lines out of sight. There are many parts to your ductwork: the main supply is the main trunk that carries the highest volume of air. Side branches allow each room in your home to be heated or cooled.

What Happens When Your Air Filter is Dirty?

What happens when your filter clogs up with dust and debris? The effects of a clogged HVAC air filter in your air conditioner or heat pump can cause failure of the system operation that will result in a call for an air conditioner repair service.

An air conditioning unit needs the proper amount air flow across the coils or heat exchanger to operate efficiently. When the filter clogs the air flow is reduced, the blower wheel works harder to draw the appropriate amount of air across the coil or heat exchanger.

It may seem counter intuitive, but when the system air flow is reduced from a restricted filter your air conditioner’s evaporator coil will begin freezing up, resulting in less air flow from the supply vents.

The Effects of Inefficient AC Systems

Inefficient central air conditioning systems make it difficult to achieve optimal indoor comfort and cause energy bills to soar. Like most homeowners, you’d probably like to stay cool and comfortable throughout the summer without breaking the bank…so change your filter regularly.

How To Remember To Change Air Filters

Here’s an easy way to stay on top of this; setup a recurring alert on your phone.  Plus, your calendar preferences let’s you set a reminder to change your your  home’s air filter every 30, 60, 90, 120 or 365 days, or the date of your choosing.

Rule of thumb for A/C Filters:

  • Seldom used home or single occupant homes without pets or allergies: Change 6-12 months
  • Typical suburban home without pets: Change every 90 days
  • Add a dog or cat: Change every 60 days
  • Multiple pets or have allergies: Change every 30-45 days

Conclusion

Changing furnace and return air filters is critical to the proper performance of your HVAC system, not to mention your home’s air quality. Studies show that indoor air pollution is one of the top five environmental health risks? We know it’s the last thing on your mind, but this is really important stuff.
