How a Heat Pump Works
- Outdoor unit — fan and compressor extract heat from outside air
- Reversing valve — switches the system between heating and cooling
- Line set — carries hot, high-pressure refrigerant indoors
- Indoor coil — releases heat into the airstream
- Warm air — the blower delivers it to the room
Heat Pump Maintenance for Portland Homes
We recommend annual maintenance for most heat pump systems. A well-maintained heat pump uses less energy, heats and cools more evenly, and lasts years longer than a neglected one. Schedule your tune-up before the season changes.
What Does a Heat Pump Tune-Up Include?
A full visit, not a filter rinse. We deep-clean the indoor head’s filters, blower wheel, and coil (where the mold and dust that cause the classic "dirty sock" smell actually live), wash the outdoor coil, verify refrigerant charge and temperature split with instruments, test the defrost cycle, clear the condensate drain, check mounting hardware and line-set insulation, and confirm the base pan drains so winter defrost water is not refreezing into an ice block under the unit. You get a straight report at the end: what we measured, what we cleaned, and whether anything is trending toward a future repair. If nothing is wrong, the report says nothing is wrong — we have no upsell quotas, so a healthy system gets a clean bill, not a sales pitch.

- Refrigerant work is done under EPA Section 608 certification, and the new circuit for the outdoor unit is permitted before it is wired.

Heat Pump Maintenance in Portland, ME FAQs
Do you offer heat pump maintenance in Portland, ME?
Yes. Portland is part of our Cumberland County service area, and J&R Mechanical Services handles heat pump maintenance for homes throughout the area. Call (207) 902-8899 or book online to schedule.
Why does my heat pump smell musty?
Moisture on a dirty indoor coil and blower wheel grows mildew, producing the well-known "dirty sock" odor. A professional deep clean of the head removes it. Regular filter cleaning and an annual service keep it from coming back.
Does maintenance really lower my energy bill?
Yes. Dirty filters and coils force the compressor to run longer to move the same heat. Restoring clean airflow and verified refrigerant charge returns the system to its rated efficiency — a difference you can see across a heating season.
