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

One of the most routine issues that we encounter at Stevenson Service Experts in Columbus is filthy air filters. They can 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 notice. Regardless if it is cooling season or heating season, having a dirty air filter can cause a host of concerns for your heating and AC system.  

So what exactly happens when you forget to swap out your air filter? Here are a just a few of the side effects you might encounter:  

  • Decreased airflow. This is easily the largest issue you’ll notice when your home’s air filter is severely clogged. The longer the air filter goes without being switched, 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 quite a bit harder to provide you with the same amount of air.  
  • Frozen coil. If your system is operating 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 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 avoid any likely damage that could come with a dirty air filter.
