Comfort Score questions

How do I know if my AC or heater is healthy?

A healthy system keeps every room comfortable, runs quietly, doesn’t trip breakers and keeps your energy bills steady from year to year. Warning signs include strange noises or smells, water or ice, short cycling, rising bills and rooms that won’t cool or heat.

How often should my AC be serviced in Arizona?

At least once a year, and many West Valley homeowners do a cooling tune-up in spring and a heating tune-up in fall. Arizona summers are hard on equipment, and a tune-up catches weak parts before they fail.

How often should I change my air filter?

Most standard filters should be changed every 1–3 months in Arizona, more often with pets or dust. A once-a-year filter is another option that takes it off your to-do list.

Is the Comfort Score an inspection?

No. It’s a quick guide based on your answers. A technician can check your system in person and tell you exactly how it’s doing.
