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

October 07, 2015

One of the most common issues that we encounter at Calverley Service Experts in Fort Worth is dirty air filters. They might seem like a very tiny piece of the big home comfort puzzle, but the role they play in helping us control comfort is a lot larger than most homeowners recognize. Regardless if it is cooling season or heating season, having a clogged air filter can cause a host 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 few of the side effects you may encounter:

  • Decreased airflow. This is easily the biggest headache you’ll note when your home’s air filter is very clogged. The longer the air filter goes without being swapped out, 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 significantly harder to provide you with the same amount of air.
  • Frozen coil. If your system is working harder because of a dirty air filter, you also run the chance 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 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 gives out 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 may 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
  • Increase in dust and debris
  • Lack of comfort

If you’re not sure when you last switched 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 filthy air filter. If you don’t know where your home’s air filter is located or you simply have a question about the number of air filters we have, give Calverley Service Experts a call at 817-380-5647 or schedule an appointment online.
