Commercial HVAC Repair in Everett, WA
Heat pump blowing cool air on a frosty morning, or an outdoor coil caked in ice? Everett’s damp cold is hard on heat pumps, and this page covers the defrost, reversing valve and backup-heat faults we fix on commercial systems.
Buildings without heat or cooling go to the top of the list, and same-day trips happen if the schedule has space; see how scheduling and triage work on the homepage.
When the heat pump can’t keep up
A commercial heat pump has to cool all summer and heat through wet, near-freezing winters. Most winter calls come down to defrost that doesn’t run, a reversing valve that won’t shift, or backup heat covering for a weak refrigerant circuit.
Winter warning signs
- Outdoor coil frozen solid and not clearing
- Cool air from the vents while the unit says it’s heating
- Electric strip heat running nonstop and power bills jumping
- A loud whoosh or no change at all when the unit should switch modes
- Units that heat fine at noon but fall behind before dawn
How the tech narrows it down
We force a defrost cycle and watch the board, sensors and reversing valve respond, then read pressures on digital manifold gauges in heating mode. Compressor and fan amps are compared with the nameplate, and the backup heat stages are checked so they help instead of hiding the real fault.

Heat pump on a packaged rooftop? RTU repair
Service area
Commercial HVAC repair in Everett reaches the Broadway offices, the waterfront, and the industrial parks near Paine Field. Our Marysville shop is just up I-5, though the actual arrival time depends on the day’s schedule.
Heat pump on a roof pad or a mezzanine? When you call about commercial HVAC repair in Everett, mention where it sits and whether it’s heating at all, and dispatch will give you a time.

Systems we see in winter
Typical jobs are packaged heat pumps on rooftops, split heat pumps with pad condensers, and air handlers with electric backup heat. For a rooftop package that needs more than heat pump work, go to rooftop unit repair.
Heat pump parts
- Defrost control boards and coil temperature sensors
- Reversing valves and the solenoid coils that move them
- Outdoor fan motors that stop during defrost and never restart
- Check valves and metering devices that stick in one mode
Backup heat and controls
- Electric heat strips with burned elements or failed sequencers
- Thermostats set to call backup heat far too early
- Outdoor temperature lockouts set wrong for our climate
- Emergency heat left on by mistake after an outage
Standards we keep
Any refrigerant we remove is captured with recovery equipment under EPA Section 608, and techs carry the license described in EPA Universal certification.
Our same-day visits depend on the board: they happen when capacity allows, and if they can’t, dispatch names the next opening up front.
Repairs are confirmed against the HVAC/R sequence of operation for that unit, so heating, defrost and backup stages hand off the way the maker intended.

If cold rooms turn into a tenant health complaint, read the EPA’s indoor air page and OSHA’s indoor environmental quality page as well.
Cold storage goes elsewhere
Coolers, freezers and ice machines are covered on the commercial refrigeration repair hub; this page is for heating and cooling the building.
Heat pump questions
Why is my heat pump blowing cold air in winter?
Often it’s stuck in a defrost cycle or the reversing valve hasn’t shifted. A tech can be there the same day when capacity allows, with heat-loss calls first.
Is ice on the outdoor unit normal?
A light frost that clears every so often is normal. A thick block of ice that stays means defrost isn’t working. Homeowners should call a residential company; we work on business and building systems.
Can you fix older heat pumps?
Usually, yes. Some older defrost boards and valves take time to order, so a nameplate photo and a short description of the fault help us bring the right parts.
How do I schedule service?
Dial (425) 535-8990, or use the contact form and tell us whether the unit is heating, cooling or neither.
Any other FAQs?

Heat pump struggling at your Snohomish County building?
The arrival time depends on the I-5 traffic, how many calls are ahead of yours, and parts, and dispatch will tell you when you call.
