How much does an AC tune-up cost in Seattle, WA?
A single AC tune-up in Seattle, WA typically costs $75–$200. Annual maintenance plans covering both the AC and furnace visits run $150–$350 a year. A real tune-up includes coil cleaning, a refrigerant-level check, drain-line clearing, and electrical testing — if the 'tune-up' is a 15-minute filter swap and an upsell pitch, it wasn't one.
What you can check yourself
- Ask what's included before booking: coils, drain line, refrigerant check, and capacitor/contactor testing should all be named.
- Book in spring or fall — tune-ups are cheaper and techs aren't rushed in the shoulder seasons.
- Keep the filter changed monthly during heavy use; no tune-up compensates for a choked filter.
- Be skeptical of parts 'about to fail' without a measurement — ask for the reading (capacitor microfarads, refrigerant pressures) in writing.
Typical cost
Typical in Seattle, WA: single tune-up $75–$200; combined heating + cooling plan $150–$350/year. Legitimate repairs found during a tune-up (capacitor $150–$350) are priced separately.
When to call a pro
A tune-up is maintenance, not repair — if your system already isn't cooling, book a diagnostic instead; tune-up pricing often excludes troubleshooting.
