Mode matters
Note whether the problem happens in heating, cooling, or both, and whether backup heat appears to run.
HEAT PUMP REPAIR / GREATER BOSTON
Heat pump trouble needs context in both modes.
Low heat, no cooling, unusual defrost behavior, auxiliary heat, noise, or a system that will not start can involve the outdoor unit, indoor equipment, controls, or electrical supply. Build a concise system brief first.
NO SIGN-INRESULTS BEFORE CONTACT DETAILS“NOT SURE” IS OKAY
01 / THE USEFUL PART
What matters before anyone quotes the work.
Outdoor conditions matter
Weather, visible ice, defrost behavior, and outdoor-unit operation add useful context without guessing a failed part.
Matched equipment
The outdoor unit, air handler or furnace, thermostat, and controls work as one system and should be identified together.
02 / SYSTEM BRIEF
Prepare the heat pump story
A short timeline and both equipment labels are more useful than a guessed diagnosis.

- 04Outdoor-unit sound, fan operation, or visible ice

03 / COST & SCOPE
Why diagnosis comes before a repair price.
Controls or equipment
Thermostat, sensor, board, airflow, defrost, electrical, and refrigerant-side issues can overlap.
Access and parts
Equipment location, component availability, and warranty approval affect the final repair scope.
Backup heat
Air-handler electric heat or a dual-fuel furnace changes the system sequence and the checks required.
The first-hour diagnostic price covers the service call and troubleshooting—not an unknown repair. HVAC PM reviews the finding, warranty status, available options, and repair price before additional work proceeds.
04 / STRAIGHT ANSWERS
Before you decide.
No contact form is required to read these answers or use the System Check.
01Is frost on the outdoor coil always a failure?+
Not by itself. Operating conditions and the defrost sequence have to be considered; heavy or persistent icing should be described for diagnosis.
02Do you repair Bosch heat pumps?+
Bosch is a core HVAC PM heat-pump focus. Model, serial, matched indoor equipment, and warranty status still need verification.
03Can I skip the System Check?+
Yes. Use Request Service at any time; the System Check simply gives HVAC PM a better handoff. The request does not reserve an instant appointment.
USE THE SITE AS A TOOL
Get the plan first. Decide what to send second.
The System Check can return a broad result early, then narrow it with equipment, installation, venting, condensate, access, and optional photos.
