Heat pump iced over, humming without starting or leaning on backup heat all week? We do heat pump repair in Lynnwood on ducted and central systems of any brand, and on central AC too. We tell you the price before the work begins.



Lynnwood sits where Puget Sound air masses collide, so a damp, near-freezing morning can follow a mild afternoon. That swing keeps outdoor units working hard and exposes weak parts quickly.
Frost is normal, and defrost melts it within minutes. A unit wearing a shell of ice points to a sensor, board or fan problem.
A stuck reversing valve, low refrigerant or a thermostat set up wrong can send lukewarm air through the vents when you want warmth.
Electric strips cost far more to run than the heat pump. If they never shut off, the outdoor unit is not doing its job.
A weak capacitor or burned contactor is the usual culprit, and a quick swap on our truck often restores it.
Cycling on and off every few minutes strains the compressor. Dirty coils, low charge or an oversized unit are the likely reasons.
Clogged filters, a tired blower motor or crushed ducts leave rooms starved. Low airflow can also freeze the indoor coil.
Prying at frost bends fins and nicks refrigerant tubing. Switch the thermostat to fan only so the ice can thaw, keep hands out of the cabinet, and call us if it returns within the day.
Same approach whether you live near Alderwood Mall or up on the Meadowdale side. No guessing, no surprise at the end of the visit.
Our tech tests pressures, electrical parts and controls. When we complete the repair the same day, that $159 comes off the bill.
We explain the failed part and quote the job. Work waits for your approval, and the price you OK is the price you pay.
Bigger jobs like a compressor or coil can be spread across 12 months with Wisetack, for buyers who qualify.
If a part must come from the manufacturer, we say so up front. The diagnostic fee is not waived when a second trip is needed.
Carrier, Trane, Lennox, Goodman, Mitsubishi and the rest. Heat pumps share the same weak points, and we carry common parts.
As a Mitsubishi Electric Diamond Contractor, we work on cold-climate heat pumps constantly, so thermostat and defrost settings are familiar.
A failed capacitor is not a reason for a new system. We bring up replacement only when repairs stop making sense.
Most heat pump faults are a part, not the whole machine. Capacitors, contactors, sensors and fan motors cost far less than a new system.
Replacement deserves a hard look when the compressor fails on a unit past its mid-teens, when a leak sits in the indoor coil, or when repair bills keep repeating. Lynnwood has plenty of 1960s and 1970s houses running aging equipment. If yours is there, we lay the repair cost beside a modern system so you decide with clear numbers.
A yearly check before the cold months catches weak capacitors, dirty coils and bad thermostat settings before they strand you.

“Had Sound Comfort out for a furnace tune-up. … They found a leaking condensate-trap joint and a weak capacitor, explained both clearly, and the tech even told me how to save money sourcing the parts myself instead of going through them. No pressure, no upsell, just straight answers. Exactly what you want from an HVAC company.”


“Service was awesome. Fast and efficient and Mauro was a delight to work with. I would recommend them to everyone!”
“Mauro was incredible. Super personable, explained things in a clear way, and did great work on our old furnace. Would highly recommend!”

We stand behind every repair we make in Lynnwood with our 100% Satisfaction Guarantee. If it does not hold up the way we promised, we return and correct it without charging you again.


Yes, in heating season. Most units check for frost every half hour to an hour and melt it in 5 to 15 minutes, with steam and a whoosh. Thick ice that lingers needs a technician.
Backup heat is often to blame. Strips run during defrost or when the system cannot keep up, and a wrong thermostat setting can keep them on. We check setup, charge and the outdoor unit.
Largely, yes. Central AC shares capacitors, contactors, fan motors and refrigerant circuits with a heat pump. During the 2021 heat dome Lynnwood hit 109 degrees, so a dead AC can’t wait.
Surges and restarts can trip safeties or damage a board. Check the breakers once, then call. Storms like the November 2022 blast left thousands of Lynnwood-area homes without power.
Only briefly if the heat pump has failed and your home has backup heat. It keeps you warm but costs much more to run. Call us promptly rather than leaving it on all week.
Mechanically, yes, but ductless repairs have their own page and parts. For wall heads or ceiling cassettes, see our mini-split service page for what we handle.
