Changing the air filter is one of the easiest ways to increase the efficiency of your heating and cooling system. A clean air filter also extends the life of your HVAC equipment, preventing the buildup of dust and unnecessary wear and tear on vital components. In most cases, the filters need to be changed at least once per season, or more often if you have pets, but in some areas, you might need to switch them out more often. 

When Should You Change Your Air Filter?

1. Dirty Filter

If the air filter is visibly clogged with dust, dirt, and hair, your heating and cooling system might be working overtime to draw in enough air. Not only does this force your equipment to work harder than necessary, but it also usually means that the air circulating through your house is dirtier.

2. Increased Allergy Symptoms

In addition to keeping contaminants out of your heating and cooling system, the air filter also traps pollen and dust that can trigger allergic reactions and asthma attacks. If anyone in your family is experiencing more severe respiratory symptoms than usual, a dirty air filter may be to blame.

3. A Dusty Home

Without a clean air filter, your HVAC system is essentially blasting dust into your home through every vent. If your shelves, furniture, and floors are constantly dusty, changing out the air filter can cut down on your housekeeping duties.
