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

October 07, 2015

One of the most routine issues that we encounter at Service Experts Heating & Air Conditioning in West Palm Beach is filthy air filters. They may seem like a very small piece of the whole home comfort puzzle, but the role they play in helping us create comfort is a lot larger than most homeowners notice. 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 couple of the side effects you may encounter:

  • Decreased airflow. This is easily the largest problem you’ll notice when your home’s air filter is badly clogged. The longer the air filter goes without being swapped out, the more dirt, dust and other particles build up. Of course, this hinders 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 as a result of a filthy air filter, you also run the risk of having the cooling coil freeze inside of the system, because it’s working overtime to give you cool air.
  • Total loss of cooling or heating. This is also a probability if your air filter goes unattended 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 may 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 diminished equipment lifecycle
  • Lower energy efficiency
  • Lower air quality
  • Increase in 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 could come with a clogged air filter. If you don’t know where your home’s air filter is located or you simply have a question about the variety of air filters available, give Service Experts Heating & Air Conditioning a call at 561-629-1826 or schedule an appointment online.
