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

One of the most routine concerns that we encounter at Service Experts Heating & Air Conditioning in Fort Lauderdale is dusty air filters. They can seem like a very insignificant piece of the overall home comfort puzzle, but the role they play in helping us maintain comfort is a lot bigger 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 switch out your air filter? Here are a just a handful of the side effects you could encounter:  

  • Decreased airflow. This is easily the biggest headache you’ll recognize when your home’s air filter is severely 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 a lot harder to provide you with the same amount of air.  
  • Frozen coil. If your system is operating harder due to a filthy air filter, you also run the risk of having the cooling coil freeze inside of the system, because it’s working overtime to provide 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 more than it should. When your system short cycles, it can overheat or break down from the added work, possibly causing damage to your system.  

In addition to these, you can also expect:  

  • A diminished equipment lifecycle  
  • Reduced energy efficiency  
  • Lower 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 get around any possible damage that might come with a clogged air filter. If you don’t know where your home’s air filter is located or you simply have a question about the various air filters we have, give Service Experts Heating & Air Conditioning a call at 954-736-4314 or schedule an appointment online.
