Heat Pump Systems We Repair in Woodinville WA

Variable-Speed / Inverter Heat Pumps
The most common configuration in Woodinville’s newer premium builds. Carrier Greenspeed, Lennox XP25, and Trane XV20i variable-capacity systems require communicating diagnostic tools to read compressor speed data, refrigerant circuit operating parameters, and fault history. We carry brand-specific interfaces for all three platforms.

Ducted Air-Source Split-System Heat Pumps
Standard two-stage and single-stage ducted heat pumps with a central air handler. Reversing valve failures, refrigerant leaks, and defrost system faults are the most common calls.

Ductless Heat Pumps (Mini-Splits)
Single and multi-zone ductless heat pumps for Woodinville’s homes and additions without ductwork. We repair all ductless heat pump brands in both heating and cooling modes.

Dual-Fuel Heat Pump Systems
Heat pump paired with a gas furnace backup. We service both systems and their staging integration — a common configuration in Woodinville’s efficiency-conscious high-end builds.

Geothermal / Ground-Source Heat Pumps
Ground-source heat pumps present in some of Woodinville’s estate properties. We service the refrigerant circuit and electrical components of ground-source systems.

Same-day heat pump repair throughout Woodinville — Hollywood District, Woodinville Wine Country, Bear Creek, North Woodinville, Cottage Lake and all surrounding areas. We carry EPA 608 refrigerant recovery equipment, digital manifold gauges, and communicating diagnostic tools for Carrier Infinity, Lennox iComfort, and Trane ComfortLink systems. Most heat pump repairs are completed in a single visit.
In Woodinville's mild winter climate, a properly functioning heat pump should comfortably cover the full heating load without auxiliary heat engaging frequently. If the heat pump is running but not maintaining set temperature, the most common causes are a low refrigerant charge from a slow leak — which reduces heating capacity proportionally — a reversing valve that's not fully shifting to heating position, a dirty or restricted outdoor coil reducing heat absorption from the ambient air, or a compressor that's operating at reduced output due to a failing start capacitor. On variable-speed systems, we access system data to see actual compressor output and refrigerant pressures rather than relying on static measurements alone.
Emergency heat mode bypasses the heat pump refrigerant circuit and relies entirely on the electric resistance auxiliary strips or gas furnace backup — which is much less efficient. Your heating bills will increase significantly if the system stays in emergency mode. Emergency heat mode is typically triggered by the thermostat when the outdoor unit fault is detected, or manually switched on. The underlying cause is almost always a compressor that's failed to start, a refrigerant pressure fault, or a reversing valve problem. We diagnose the root cause and restore the heat pump to normal operation.

Our refrigerator stopped properly cooling. While it wasn't completely out. it just wasn't cool enough to keep things fresh. Called Hotwire on Friday. Technician came out Saturday morning. Vlad is a young fellow but very knowledgeable. He quickly diagnosed the problem which was a frozen stuck fan. After removing the freezer tray, he pulled out his magic steamer gadget and defrosted the coils. He did a thorough job cleaning up and putting everything together. Happy to have things running again ahead of Superbowl Sunday.

The team here was great. I had an issue with a dishwasher, they were quick to diagnose it and informed us of reasonable alternatives. We chose to repair it, they ordered the part and installed it. Throughout, they were communicative, helpful, and nice. The price was reasonable as well. I'd go back to them for any appliance issues in the future!

My LG fridge/freezer stopped cooling. I called Rain City around 8pm, and they were able to get a technician out before Noon the next day. After inspecting the problem the tech informed me that the compressor went out, which is a somewhat common problem on LGs. He'd be able to fix it right away if I wanted. Given the labor needed to replace the compressor, I decided to just replace the refrigerator instead.
I was pleased how he explained the issue and presented me with various options. I'd definitely recommend.
