Twice-yearly heat pump tune-ups across the metro.
Heat pumps work all year, so one visit a year leaves half the system unchecked. We split tune-ups spring + fall to catch both sides.

What's in a tune-up
What's included in our $140 heat pump tune-up — six checks, every visit.
Heat pumps are more complex than furnaces or ACs — variable-speed compressors, reversing valves, defrost boards, inverter fault histories. We check the parts most shops skip.
Refrigerant pressures in both modes
Heat pumps run refrigerant in heat AND cool. We verify pressures in both directions — half the system is hidden if you only check one.
Defrost cycle test
Defrost board, defrost sensor, and reversing valve cycled through. Most "iced over" winter calls trace back to a defrost cycle that was never verified at the last tune-up.
Filter inspection & swap
Standard 1" filters checked or replaced. Restricted airflow kills inverter compressors faster than anything else — caught early.
Coil cleaning, both sides
Outdoor coil cleared of cottonwood and PNW moss. Indoor evaporator coil inspected for dust buildup. Clean coils run quieter and 5–15% more efficiently.
Inverter & electrical check
Capacitors, contactors, inverter board fault history pulled, amp draws verified to spec. Variable-speed compressors need clean power — we confirm it.

Why tune up
Why annual heat pump maintenance pays for itself — three reasons.
Twice-yearly, not once
Heat pumps heat AND cool, so they get used year-round. We schedule spring (cooling-side check) and fall (heating-side check) so neither half ever drifts a full year.
Keep the warranty valid
Trane and Mitsubishi heat pump warranties require annual maintenance. Skip it and the manufacturer can deny a compressor claim — the most expensive part on the system.
Lower bills, longer life
A tuned heat pump runs 10–20% more efficiently and lasts years longer. The cheapest insurance you can buy against a $6,000+ compressor failure.
Want both visits on autopilot?
Comfort Care Plus bundles spring + fall.
Both heat pump tune-ups included, priority service, and member-rate pricing on repairs. Most plans pay for themselves the first season.
On every tune-up
Inverter heat pumps deserve more than a filter swap.
Modern variable-speed heat pumps run quieter and more efficiently than the systems they replaced — but they're unforgiving about deferred maintenance. We test refrigerant in both modes, pull inverter fault history, cycle the defrost board, and verify the reversing valve. The full picture, every visit.
- Refrigerant pressures verified in heat AND cool
- Defrost cycle triggered and confirmed
- Inverter fault codes pulled from the control board
- Reversing valve cycled and confirmed

Heat pump tune-up questions, answered.
- Twice a year is ideal — spring before cooling season, fall before heating season. Heat pumps work year-round, so a once-a-year visit leaves half the system unchecked for 12 months. Our Comfort Care Plus plan bundles both visits.
- A heat pump has more moving parts than an AC: a reversing valve, defrost board, defrost sensor, and (often) an inverter compressor. We test those components in both heat and cool modes — an AC tune-up only checks the cooling side. Skipping the heating-side checks is why most heat pumps fail in January, not July.
- About 75–90 minutes for a standard residential heat pump. Inverter / variable-speed systems and multi-zone setups can run longer because there are more components to verify. We tell you up front if anything is out of spec.
- $140 flat for a one-off spring or fall tune-up. The Comfort Care Plus plan bundles both annual visits plus member-rate pricing on any repair the tech catches — most plans pay for themselves the first season. See Maintenance Plans for the breakdown.
- Yes. Trane, Mitsubishi, Carrier, Lennox, Goodman, Bryant, American Standard, and more. Factory training on the major brands and access to manufacturer fault-code documentation, so we can pull inverter codes and history on systems other shops skip.
- Not as part of the flat-rate tune-up. If we find a low charge, we quote the leak search and recharge separately — heat pumps shouldn't lose refrigerant in normal operation, so a low charge means something is leaking and needs repair, not just topping up.
