The Importance of Changing Your Air Filter

October 27, 2013 | Blog

It’s no secret that buying a new air conditioning and heating system is a big investment. So, naturally, you should do everything possible to protect that investment.

One of the simplest ways to do that falls on the homeowner’s shoulders. It’s a task that, unfortunately, often goes ignored: changing out your air filter.

Why is the air filter so important?

Do you know what it feels like to drink a thick milkshake through a flimsy straw? That’s what your HVAC system feels like trying to cycle air through your home with a clogged filter.

Some of the effects that dirty air filters can have on your HVAC system include:

  • Reduced energy efficiency (which will show in your electricity bill)
  • Unpleasant odors and allergens in your air
  • Dirty evaporator coils

While the list above names a few of the direct problems neglecting your air filter can cause, these problems can cause even more severe issues with your HVAC system, such as clogging the system and frozen coils. Don’t let a small task ruin your HVAC system — change your air filter regularly.

How often should you switch your air filter?

It’s a good habit to check your air filter once a month – especially during the hottest and coldest times of the year. If you check the filter and it’s dirty, switch it out. If you suffer from allergies or have a pet, especially a dog or a cat that sheds a lot, you should check your air filter once a month all year.

If you don’t have allergies or pets, months in which you aren’t using your HVAC system as much will be different. During these non-peak months, you can switch your filter every two to three months. That said, every home is different, so you should still check your air filter monthly to determine the best habits for your HVAC system.

What type of air filter should you use? 

Pleated air filters produce the best results in terms of efficiency and air quality. These filters cost a bit more, but it’s a smart investment in your home’s electric bill and family’s health.
