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

One of the most basic issues that we hear about at Stallion Heating and Air Conditioning in Philadelphia is dusty air filters. They may seem like a very insignificant piece of the whole home comfort puzzle, but the role they play in helping us control comfort is a lot bigger than most homeowners notice. Regardless if it is cooling season or heating season, having a filthy air filter can cause a number of issues for your heating and AC system.  

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

  • Diminished airflow. This is easily the largest problem you’ll note 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 a lot harder to leave you with the same amount of air.  
  • Frozen coil. If your system is running harder because of a clogged air filter, you also run the risk of having the cooling coil freeze inside of the system, because it’s running overtime to give you cool air.  
  • Total loss of cooling or heating. This is also a threat if your air filter goes unchanged 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 all the time. 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 shortened equipment lifecycle  
  • Decreased energy efficiency  
  • Lower air quality  
  • Greater dust and debris  
  • Lack of comfort  

If you’re not sure when you last changed your air filter, it may be a good time to do so in order to get around any possible damage that could come with a filthy air filter.
