What is an HVAC tune-up for?

Regular maintenance gives a professional a chance to check your heating and cooling equipment and explain its condition. Ask what the visit includes for your particular system, what was found and what needs further attention.

A maintenance visit is different from a repair guarantee. Agree on the scope before work begins, and ask your technician about manufacturer guidance for your equipment. Keep a record of the visit so you can compare findings over time.
