What Happens to a Heating and Cooling System When the Air Filter Isn’t Changed in Charleston?

One of the most routine issues that we hear about at Pardee Service Experts Heating & Air Conditioning in Charleston is dirty air filters. They might seem like a very tiny piece of the whole home comfort puzzle, but the role they play in helping us control comfort is a lot larger than most homeowners notice. Regardless if it is cooling season or heating season, having a dirty air filter can cause a variety of issues for your heating and AC system.

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

• Diminished airflow. This is easily the largest issue you’ll recognize 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 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 working harder due to a clogged air filter, you also run the chance 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 excessively. When your system short cycles, it can 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
• Diminished air quality
• Greater dust and debris
• Lack of comfort
