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

One of the most basic problems that we encounter at Service Experts Heating, Air Conditioning & Plumbing in the U.S. is dusty air filters. They can seem like a very small piece of the overall home comfort puzzle, but the role they play in helping us create comfort is a lot bigger than most homeowners notice. Regardless if it is cooling season or heating season, having a dirty air filter can cause a host of issues 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:  

  • Reduced airflow. This is easily the largest issue 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 prevents air from passing through the filter as it should, meaning your system is working quite a bit harder to give you the same amount of air.  
  • Frozen coil. If your system is operating harder due to a dirty air filter, you also run the danger of having the cooling coil freeze inside of the system, because it’s operating 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 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 could overheat or break down from the added work, possibly causing damage to your system.  

In addition to these, you can also expect:  

  • A shortened equipment lifecycle  
  • Decreased energy efficiency  
  • Decreased air quality  
  • Increase in 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 avoid any possible damage that might come with a dirty air filter.
