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 Ravenna is dusty air filters. They might seem like a very tiny piece of the whole home comfort puzzle, but the role they play in helping us maintain comfort is a lot greater than most homeowners realize. Regardless if it is cooling season or heating season, having a clogged air filter can cause a host of problems for your heating and AC system.

So what exactly happens when you neglect to change your air filter? Here are a just a couple of the side effects you could encounter:

  • Diminished airflow. This is easily the largest headache you’ll notice 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 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 operating harder due to a clogged air filter, you also run the danger 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 probability if your air filter goes unchanged 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 all the time. When your system short cycles, it could overheat or break down from the added work, potentially causing damage to your system.

In addition to these, you can also expect:

  • A shorter equipment lifecycle
  • Reduced energy efficiency
  • Decreased air quality
  • Greater 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 dirty air filter.
