Heat Pump Repair in Redmond WA

Heat pump diagnostics require a specific skill set that not every HVAC company has in-house — refrigerant handling under EPA Section 608, brand-specific error code reading, reversing valve testing, and inverter compressor troubleshooting. Our Redmond techs carry the certifications and the diagnostic tools that let us find the actual fault rather than swapping parts on guesswork.

We repair heat pumps regardless of who did the original install, which matters in Redmond because so many systems were put in during Energy Smart Eastside rebate rush periods by installers who’ve since moved on. Whether the paperwork is still valid or not, we can service the equipment and honor manufacturer warranty procedures where they apply.

Every heat pump repair in Redmond comes with a 90-day parts and labor warranty, and our vans stock Mitsubishi parts particularly deep since that’s the dominant brand across the city’s ESE conversions. Refrigerant recharge, control board swap, sensor replacement, and defrost cycle tuning are all standard first-visit fixes for us.

For Redmond heat pumps installed under Energy Smart Eastside, the systems are almost always Mitsubishi cold-climate units with inverter compressors. That’s a different diagnostic approach than older on/off compressors — inverter faults show up as specific error codes rather than obvious symptoms. Our techs are trained on this equipment class specifically, which is why our first-visit fix rate on ESE-installed systems runs high.
