Once an HVAC pro comes to your house to do an annual inspection and maintenance, the major work is done for the year unless your system breaks down between visits. But that doesn’t mean you don’t need to deal with your a/c until next year’s inspection.
You’re smart to keep your a/c system tuned up, but maintenance is a monthly chore as long as it’s hot outside. Change your a/c filter every month. If you don’t, it can collect enough dirt and dust to become clogged—and that means your a/c won’t get the air it needs to work properly. The result: You will end up with dirtier air, a higher electric bill and an a/c that will wear out before its time.
A tip: Make it a habit to change your filter whenever you pay your monthly electric bill.
