Heat pump maintenance covers inspecting refrigerant levels, cleaning the outdoor coil and indoor filter, checking electrical connections, testing thermostat calibration, and clearing condensate drains. Most homeowners in Western Washington schedule this once a year, ideally before fall heating season or before summer cooling demand picks up. Homes near Puget Sound deal with moisture, moss, pollen, and coastal air that clog coils faster than in drier climates, so regular service helps protect efficiency and system lifespan.
Symptoms we see daily
Signs you need heat pump maintenance
Ice buildup on the outdoor unit that doesn't clear during normal defrost cycles

Weak airflow from vents or a musty smell when the system starts up
Short cycling, where the unit turns on and off more often than it used to
No surprises
How a heat pump maintenance visit works
1
Schedule and System Review
We ask about your system's age, any recent issues, and when it was last serviced so the technician arrives prepared for your specific setup.
2
Outdoor Unit Inspection
The technician checks the outdoor coil, fan motor, and refrigerant lines, clearing away leaves, moss, or debris that build up around units in Western Washington yards.
3
Indoor Coil and Filter Service
Indoor coil and filter get cleaned or replaced, and the condensate drain is checked and cleared to prevent water backup or leaks.
4
Refrigerant and Electrical Check
Refrigerant charge, electrical connections, and thermostat calibration are tested to confirm the system is cycling correctly and holding temperature as designed.
5
Test Run and Report
The system runs through a full heating and cooling cycle while the technician confirms performance, then walks you through findings and any recommendations before leaving.

Straight answers
Heat Pump Maintenance questions we hear most
How often should I get my heat pump serviced in the Seattle area?
Once a year is standard for most homes in King and Snohomish counties. Scheduling in spring or early fall works well, since it puts the system in good shape before the heaviest heating or cooling demand of the year.
Does maintenance actually lower my PSE or Snohomish PUD electric bill?
A clean, properly charged heat pump doesn't have to work as hard to hit the same temperature, which typically shows up as steadier electric usage over time. Neglected coils and clogged filters force the system to run longer to do the same job.
Can I handle any of this myself?
Replacing or rinsing an accessible filter is fine for most homeowners. Refrigerant checks, electrical testing, and coil cleaning on the outdoor unit involve tools and safety steps that are best left to a licensed technician.
What's the difference between a maintenance visit and a repair call?
Maintenance is a scheduled, preventive visit meant to catch small issues early. If the technician finds a failing part or a bigger problem during the visit, that repair is quoted and billed separately from the maintenance service.
