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

October 07, 2015

One of the most routine problems that we hear about at Service Experts Heating & Air Conditioning in Orlando is dusty air filters. They may seem like a very insignificant piece of the overall home comfort puzzle, but the role they play in helping us control 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 number of concerns for your heating and AC system.

So what exactly happens when you don’t remember to change your air filter? Here are a just a handful of the side effects you might encounter:

  • Diminished airflow. This is easily the greatest issue you’ll notice 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 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 due to a clogged air filter, you also run the chance of having the cooling coil freeze inside of the system, because it’s working overtime to provide you with cool air.
  • Total loss of cooling or heating. This is also a possibility if your air filter goes neglected for months and months on end. In essence, you will have worked your system so hard that something quits working or wears out and needs to be replaced or serviced.
  • Short cycling. Short cycling means the heating and cooling system turns on and off excessively. When your system short cycles, it can 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
  • Lower energy efficiency
  • Lower 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 get around any likely damage that might come with a clogged air filter.
