Job constraint we check
We test heating, cooling, defrost, reversing valve behavior, and inverter faults before leaving. No-AC or undersized add-on AC on 1980s gas-furnace homes — the most common service request June through September.
Permit and paperwork
Most repairs in Gresham do not need a permit. If the call turns into replacement, panel work, or a larger code item, we flag that before quoting the next step.
Review/case note
On Gresham heat pump calls, a system can cool normally and still fail in defrost or heat mode. We run both modes before calling it fixed.

Heat pump diagnostics
Heat pump repair in Gresham means testing both modes.
Heat pumps are more complex than furnaces, and most repair shops don't train their techs deeply on the variable-speed inverter side. We do. Common faults: refrigerant leak, frozen outdoor coil from a stuck defrost cycle, failed reversing valve, or inverter board faults that throw manufacturer-specific codes.
We pull fault codes with manufacturer tools, verify refrigerant pressures by mode, test the defrost sequence, and check electrical at the contactor. Real diagnostics — not guess-and-replace.
Heating mode
Supply temperature, refrigerant pressures, and aux heat behavior.
Cooling mode
Reversing valve operation and charge behavior under cooling load.
Defrost cycle
Board, sensor, coil condition, and ice pattern.
Inverter and electrical
Fault codes, board communication, contactor, and line voltage.
Heat Pump Repair questions Gresham homeowners ask
- Yes — we cover every ZIP in Gresham (97030, 97080) and the surrounding Multnomah County area. 100% Satisfaction Guaranteed on every job.
- We're 30 minutes from our Oregon City shop, so trucks are rolling through Gresham most days of the week. Same-day diagnosis on most heat pump repair calls.
- No-AC or undersized add-on AC on 1980s gas-furnace homes — the most common service request June through September.
- Heat pumps build a small ice layer in heating mode. That's normal, and a defrost cycle melts it every 30–90 minutes. If the unit is fully encased in ice, the defrost cycle isn't running.
- Aux heat is normal during very cold weather (below ~30°F). But if it's running on a 45°F day, something is wrong: usually low refrigerant, a stuck reversing valve, or an undersized system.
