Make Changing the Air Filter a Year-Round StrategyOne of the easiest and least expensive things your can do to keep your heating and cooling systems operating at peak efficiency is to change your air filters on a regular basis. Standard air filters are usually less than $5, so there’s no excuse not to stay on top of this maintenance task.

When to change your filter

HVAC professionals advise inspecting your HVAC filters every month, and then changing them when they look dirty. The frequency of changing the air filter will vary depending on several factors including the type of filter, how much the conditioning system is being used and whether your home has pets, carpeting and a lot of in-and-out traffic (kids!).

Why changing the air filter is important

Keeping your air filters clean is important for a variety of reasons.

  • Extends the life of your heating and cooling systems. Changing the air filter as recommended can help your mechanical systems last longer. A furnace or air conditioner has to work harder to push air through a clogged filter.
  • Saves energy dollars. Using that same logic, a system that’s laboring to push air through a dirty air filter uses more energy, costing you more on your utility bills.
  • Reduces dust and allergens. The primary function of the air filter is to remove pollutants from the air before it gets circulated through your living spaces.
  • Keeps your ducts clean. When the filter catches dust and other particles, they don’t get sent through your ductwork, which helps keep that system cleaner, longer.

How to change your air filter

Changing the air filter in your furnace, heat pump or air conditioner is easy. You simply remove the old filter and insert a clean one. The air filter is usually located at the front of your system near the fan motor. You’ll need to check the size before you go to the hardware store for new filters as each unit is different. You’ll also have to decide how efficient your filter needs to be. Consult with an HVAC expert to find the best air filter for your home situation and HVAC system.
