A heat pump is a common choice in Waxhaw because it carries both heating and cooling efficiently through our mild Piedmont winters, pulling warmth from the outside air instead of burning fuel. When one acts up, though, it doesn’t fail like a straight AC or a furnace, and on the variable-speed and multi-zone systems you find in the bigger homes here, the diagnosis is where the job is won or lost.
Here’s the promise up front: we don’t make money by scaring you. A company that shows up at a large home and sees an aging system has every reason to find a reason you need a whole new one before they’ve even diagnosed it. We’d rather fix the reversing valve — our $89 diagnostic tells us what’s actually wrong first — and have you call us again in five years.
The heat-pump calls we see most:
- Heats but won’t cool, or the reverse — a stuck or failed reversing valve, the component that reverses refrigerant flow between modes.
- Outdoor unit frozen solid — a defrost-cycle fault: a bad defrost board, a failed sensor, or a reversing valve leaving the coil iced.
- Runs nonstop, never satisfies — low refrigerant from a leak, which drops capacity in both modes, or auxiliary heat that isn’t engaging on schedule.
- Strip heat running constantly — usually a charge or control fault forcing the expensive backup heat to carry the whole load, and you feel it on the power bill.
Repair It, or Plan a Replacement?
Heat pumps generally give you 12 to 15 years. If yours is in that range and the compressor or the reversing valve has failed — the two priciest parts — we’ll set the repair cost beside a replacement cost so you can see the math, not just hear an opinion. A newer unit on its first fault almost always gets repaired.
We keep capacitors, contactors, defrost boards, and refrigerant on the truck, so most repairs wrap the same day. We service and install heat pumps of every make and model for homeowners across Waxhaw and Union County — roughly a 20-minute run from our shop, out toward the Cuthbertson Road side of town. Every job carries up to a 10-year labor and parts warranty, and veterans save 10%.
