Change air filter to save money and energy

It only takes a couple of minutes to change the air filter in your heating/cooling system. It’s simple and easy and can save you money.

But that’s not all you can save. A dirty air filter makes your system work harder to keep you cool, which wastes energy. Changing your air filter regularly helps to ensure efficient operation and keep your electricity bill in check. What’s more, a dirty air filter allows dust and dirt to build up in your system. Changing your air filter regularly can reduce the need for costly maintenance and prevent damage to your system.

And when winter arrives, it’s just as important to change your air filter regularly. Your heating system needs to work as efficiently as possible to keep you warm, and a clean air filter helps it do that.

Experts recommend turning your system off before changing the air filter. Make sure that the arrow on the filter—which indicates the direction of the airflow—is pointing toward the blower motor. When you’ve made the change, turn your system back on. To save time, it’s a good idea to keep a couple of spare filters on hand.
