Service your HVAC at least once a year — a thorough professional tune-up, ideally in spring before cooling season. A heat pump, which heats and cools year-round, benefits from that same annual tune-up so both modes stay in tune. Between visits, check or change filters every 1–3 months. Regular service keeps efficiency up, prevents most emergencies, and is usually required to keep your manufacturer's warranty valid.
What does "servicing" your HVAC actually mean?
A professional tune-up is more than a filter swap. A technician checks refrigerant charge, cleans the coils, inspects electrical connections and the blower, tests safety controls, clears the condensate drain, and verifies airflow and temperature split. On a heat pump they also confirm the reversing valve and defrost cycle work correctly. The goal is to catch small problems while they're cheap and keep the system running at its rated SEER2 efficiency.
What's the right schedule?
- Once a year (ideally spring, before cooling season): a full professional tune-up of your heating and cooling system — the single visit that does the most for efficiency and reliability.
- Every 1–3 months: check the air filter; replace when dirty. Homes with pets, allergies, or recent wildfire smoke need it more often.
- Annually: have your water heater checked too — sediment flush for tanks, descaling for tankless units.
Why does the Bay Area climate change the math?
Our coastal air is mild but carries salt and moisture that can corrode outdoor coils over time, and many homes run their systems lightly — which sounds gentle but lets dust and algae build up in ducts and condensate lines between heavy-use spells. Wildfire smoke season also loads filters fast. Light, steady use is exactly the pattern that makes a missed tune-up sneak up on you, so a consistent annual tune-up matters more here than the raw runtime hours suggest.

What happens if you skip it?
Skipped maintenance is the most common cause of avoidable breakdowns. A clogged condensate line trips the safety shutoff on the first hot day; a dirty coil makes the compressor work harder and shortens its life; low refrigerant quietly raises your bill for months. Most "my AC died in a heat wave" calls trace back to something a tune-up would have caught. If your system is already aging, our repair-or-replace guide helps you decide whether to keep investing in it.
Warranty protection. Most manufacturers require documented annual maintenance to honor parts coverage. Keeping your tune-ups on schedule protects the investment you already made in the equipment.

Common questions
How often should I service my HVAC system?
At least once a year — a thorough professional tune-up, ideally in spring before cooling season. A heat pump heats and cools year-round, so that same annual tune-up keeps both modes in tune. Change or check filters every 1–3 months in between.
Do heat pumps need more maintenance than a furnace and AC?
Not more — but it should be consistent. Because a heat pump works in both seasons, a thorough annual tune-up keeps the refrigerant charge, coils, and reversing valve in good shape and protects the manufacturer's warranty.
Is a maintenance plan worth it?
For most homeowners, yes: it bundles your annual tune-up, keeps you on schedule, and usually includes priority service and small discounts. The bigger value is catching a failing part before it becomes a no-heat or no-cool emergency.
