What Happens When You Don't Change Your Furnace's Air Filter

October 07, 2015

One of the most basic problems that we come acress at Comfort Masters Service Experts in Wheeling is dusty air filters. They can seem like a very insignificant piece of the overall home comfort puzzle, but the role they play in helping us maintain comfort is a lot bigger than most homeowners realize. Regardless if it is cooling season or heating season, having a dirty air filter can cause a variety of concerns for your heating and AC system.

So what exactly happens when you forget to change your air filter? Here are a just a handful of the side effects you may encounter:

  • Decreased airflow. This is easily the biggest headache you’ll recognize when your home’s air filter is severely clogged. The longer the air filter goes without being changed, the more dirt, dust and other particles build up. Of course, this prevents air from passing through the filter as it should, meaning your system is working a lot harder to provide you with the same amount of air.
  • Frozen coil. If your system is operating harder because of a dirty air filter, you also run the danger of having the cooling coil freeze inside of the system, because it’s running overtime to provide you with cool air.
  • Total loss of cooling or heating. This is also a threat if your air filter goes unattended for months and months on end. In essence, you will have worked your system so hard that something breaks or wears out and needs to be replaced or serviced.
  • Short cycling. Short cycling means the heating and cooling system turns on and off more than it should. When your system short cycles, it could overheat or break down from the added work, which could end up causing damage to your system.

In addition to these, you can also expect:

  • A shorter equipment lifecycle
  • Decreased energy efficiency
  • Diminished air quality
  • More dust and debris
  • Lack of comfort

If you’re not sure when you last swapped out your air filter, it may be a good time to do so in order to avert any likely damage that might come with a filthy air filter.
