Why You Should Change Your Air Filters When Dirty

It’s been a long, cold winter here in Louisville and Southern Indiana, and our furnaces have been working overtime heating our homes up. An often neglected yet important part of your heating system is your air filter, especially if it’s dirty. Replacing and keeping your air filter clean is one of the simplest steps in keeping your heating costs down during the cold winter months, for a couple of reasons.

  • Extending Heating System Life. If the hot air intended for your home is clogged or blocked, it can overheat your main heating unit, which leads to cracks, damaged duct work, and leaks, which can also come with a hefty repair bill.
  • Air Flow. A clogged dirty air filter doesn’t allow hot air into your home, instead trapping it in the dirt and dust in your filter. The heat trapped by those particles is wasted and never reaches your home, increasing your heating costs.
  • Air Quality. The more particles that are trapped in your air filter, the fewer particles your air filter is actually preventing from getting out into your home. If you suffer from allergies, it won’t take long for a bad air filter to fill your home with dust, pollen, and other irritants.

March spells the beginning of the end of the cold season here in Louisville and Southern Indiana, but that doesn’t mean your heating system is out of the wood just yet. Check your air filter and make sure your heating unit is putting out the heat it’s supposed to, instead of just heating up dirt!
