Heat Pump Repair

Heat pump repair in Soddy Daisy — measured, not guessed.

A heat pump heats and cools, which means it runs nearly every day of the year — and it's far less forgiving of a sloppy charge or a restricted duct than a furnace. We diagnose it the way it needs to be diagnosed: with instruments.

Signs your heat pump needs repair

Lukewarm air in heating mode, ice that won't clear from the outdoor unit, a system stuck in defrost, auxiliary or emergency heat running when it shouldn't, rising bills, or a unit that runs constantly without holding the setpoint.

Because a heat pump moves heat instead of burning fuel, small problems with charge or airflow show up fast as comfort complaints. The good news is they're measurable.

Why heat pumps demand measurement

Heat pump performance is unusually sensitive to refrigerant charge — a system that's even modestly over or undercharged loses capacity and efficiency, and the symptoms mimic a dozen other faults. The only way to know is to measure superheat and subcooling against the conditions, not to trust the gauge needle and move on.

Airflow matters just as much. We read static pressure with a manometer and confirm delivered airflow with the ALNOR balometer, because a heat pump starved by an undersized or leaky duct system will never perform the way the equipment is rated to.

Repairs we handle

Reversing valves, defrost boards and sensors, contactors and capacitors, fan and blower motors, refrigerant leaks repaired and recharged by weight, and the airflow and duct-leakage problems that masquerade as equipment failures. We use an IR camera to confirm electrical and temperature issues before we condemn a part.

Repair or replace?

Compressors and reversing valves are the expensive failures, and on an older heat pump the math sometimes favors replacement. When it does, we run a Manual J load calculation so the new system is sized to your home — not to the unit that's failing. You'll have the data and a written estimate before you decide anything.

Common questions

Heat Pump Repair questions, answered straight.

Why is my heat pump blowing cool air in heating mode?
Lukewarm air can mean low charge, a stuck reversing valve, a defrost fault, or backup heat that isn't engaging. Each one reads differently on the gauges, so we measure superheat, subcooling, and airflow before we name the fix.
My outdoor unit is covered in ice — is that normal?
A little frost that clears on a defrost cycle is normal. Ice that won't clear is not, and it usually points to charge, a defrost control, or airflow. We measure rather than guess at which one.
Why does heat pump refrigerant charge have to be so exact?
Heat pump capacity is unusually sensitive to charge — even a modest over- or undercharge loses efficiency and mimics other faults. We check it against measured superheat and subcooling, not the needle on a gauge.
