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

October 07, 2015

One of the most common concerns that we come acress at Service Experts Heating & Air Conditioning in Medina is dusty air filters. They might seem like a very small piece of the big home comfort puzzle, but the role they play in helping us create 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 don’t remember to swap out your air filter? Here are a just a few of the side effects you could encounter:

  • Decreased airflow. This is easily the largest headache you’ll recognize when your home’s air filter is very clogged. The longer the air filter goes without being changed, the more dirt, dust and other particles build up. Of course, this inhibits air from passing through the filter as it should, meaning your system is working significantly harder to give you the same amount of air.
  • Frozen coil. If your system is working harder because of a dirty air filter, you also run the risk of having the cooling coil freeze inside of the system, because it’s working overtime to leave you with cool air.
  • Total loss of cooling or heating. This is also a threat if your air filter goes neglected 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 can overheat or break down from the added work, potentially causing damage to your system.

In addition to these, you can also expect:

  • A diminished equipment lifecycle
  • Decreased energy efficiency
  • Decreased air quality
  • Greater 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 avoid any possible damage that could come with a dirty air filter.
