Do I Really Need To Change The Air Filter?

If you’ve done any reading online about home maintenance, chances are you’ve seen the advice for keeping your air filter clean. After all, your home’s heating and cooling system is one of the most important systems in your house. And if a clean air filter can help it run better, it’s only natural that you should change it out once in a while to keep everything in good working condition. 

Do I Really Need To Change The Air Filter?But did you know your air filter does more than keep dirty air particles out of the air you breathe?

To start, a good air filter helps clean the air. It takes out many of the air particles that come into your home and circulates from room to room. Things like mildew, biological growth, pollen, pet dander, and more are consistently moving throughout your home every time your heating or cooling system fire up and push air through the ventilation system. 

What circulates throughout your home also ends up back in the system itself. While conditioned air flows into your rooms to keep you comfortable, it also flows back into the air handler for the air conditioner to cool or the furnace to heat it. If a good air filter isn’t in place, that debris goes back into the system and has a chance to do irreparable damage. 

When an air filter gets too dirty, it harms your hvac system. If the dirt builds up for weeks – months – it can be almost as bad as having no air filter at all. A clean air filter traps the dust and debris before it enters. Without an air filter, dirt and debris would have free reign to move into the system. With a dirty air filter, even more dust and biological growth can enter your system every time it runs. 

The system is designed to take in a certain amount of air every time it operates. If it doesn’t get the proper levels, the system compensates for the loss. And over time, that can mean malfunction, even bringing the system to a halt. That means unnecessary repairs before their time. And possibly replacing the system long before it’s due. 

What should you do instead? It’s really as easy as replacing your air filters on a regular basis. This one simple act is the best way to ensure a return on investment with one of the most expensive systems in your home.
