How Often Should I Change My Air Filter?

It's the cheapest thing you can do for your heating and cooling system, and the easiest to forget. Here's a simple guide for Plano homes.

1. Basic 1-inch filters

Change these every 1 to 2 months. In the middle of a Texas summer or a cold snap, when the system runs all day, check monthly.

2. Thicker 4- to 5-inch filters

These usually last 6 to 12 months. Check the label and write the date on the frame.

3. Pets, allergies, or construction

Dogs, cats, dust from a remodel, or spring pollen in Collin County fill a filter faster. Go with the shorter schedule.

4. Signs it's overdue

The filter looks gray, airflow feels weak, rooms heat or cool unevenly, or your energy bill creeps up.

5. Why it matters

A clogged filter makes your system work harder, wears out parts sooner, and can even cause a furnace to overheat and shut off.
