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

One of the most common issues that we encounter at Parker Pearce Service Experts in Gaithersburg is dirty air filters. They can seem like a very small piece of the overall home comfort puzzle, but the role they play in helping us control comfort is a lot larger than most homeowners realize. 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 change your air filter? Here are a just a few of the side effects you could encounter:  

• Diminished 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 inhibits 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 working 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 give you cool air.  
• Total loss of cooling or heating. This is also a possibility if your air filter goes unattended for months and months on end. In essence, you will have worked your system so hard that something quits working 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 may 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  
• 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 avert any potential damage that could come with a dirty air filter.
