Heat Pump Repair
Our Heat Pump Repair Starts With What Failed
When a heat pump isn’t keeping up, the fault’s usually in the defrost controls, the reversing valve or the refrigerant charge. Winter or summer, you can call us for heat pump repair in Indian Trail. We find the failed part before anybody brings up a new system. Most calls start with a house that won’t warm up, an outdoor unit caked in ice, or a thermostat stuck on aux heat.
Most North Carolina homes heat with electricity, and most of those use a heat pump. January nights around Indian Trail regularly drop to freezing, and on those nights frost forms on the outdoor coil. A healthy heat pump melts it off with a short defrost cycle. When the defrost board or the outdoor temperature sensor fails, the ice buildup keeps growing until the coil can’t pull heat from the air.
On a call like that, we test the defrost board, the sensor and the reversing valve. Then we get the heat pump carrying the house again, so the heat strips aren’t running all day. We’re a local heating contractor, and we fix furnaces as well as heat pumps. If the vents feel cool, our guide to a heat pump blowing cold air sorts normal defrost air from a real fault.

How Our Heat Pump Service Visit Goes
Call or text (980) 414-5046 any day from 6am to 10pm, and we offer same-day service most days. The visit runs the same way whether the coil’s iced over or the strips won’t shut off.
1. Tell Us What It’s Doing
Describe what’s going on and when it started. A photo of the outdoor unit’s data plate, the thermostat screen or an iced coil gives the tech a head start before the visit.
2. Start Inside at the Air Handler
A good tech checks the thermostat settings first, since a setup that’s wrong for a heat pump can call for strips it doesn’t need. The filter, the air handler and the heat strips come next.
3. Test the Outdoor Unit
Outside, we test the capacitor and contactor that start the compressor, then check the refrigerant charge. A low charge means there’s a refrigerant leak somewhere, and we find and repair it. We also look over the outdoor coil, since dirt and bent fins cut the airflow it needs.
4. Watch a Full Defrost Cycle
Running the heat pump through a defrost cycle shows whether the defrost board, the outdoor temperature sensor and the reversing valve are working together. If the board never calls for defrost or the valve won’t shift, we know which part failed.
5. Repair and Warranty
Some parts, like a defrost board or a reversing valve, aren’t always on hand and may need to be ordered. The repair carries our 1-year labor warranty. A part we install keeps its manufacturer coverage, and the length depends on the model.
Auxiliary Heat Running on Mild Days?
Auxiliary heat is the set of electric heat strips in your air handler. Every heat pump has a balance point, an outdoor temperature where it can’t keep the house warm by itself. Below that point the strips come on to help, and that’s normal. A big overnight thermostat setback can bring them on too, when it asks for several degrees at once in the morning. When they run on mild days, something is making the heat pump hand off too early.
Duke Energy Carolinas and Union Power Cooperative both serve Indian Trail, and on either bill, strips running all day stand out. When the heat pump keeps handing off, we trace the cause. It’s usually thermostat settings meant for a furnace, a low refrigerant charge, a weak compressor or a defrost board stuck mid-cycle.
Heat in July? It May Be the Reversing Valve
A reversing valve lets one outdoor unit heat in winter and cool in summer, and it shifts again for every defrost cycle. When it sticks, you get heat in July or cool air in January. Sometimes the valve itself has failed, and sometimes it’s the solenoid coil that moves it, a smaller repair.
A compressor that won’t start gets blamed first, but a failed capacitor or burned contactor can stop it cold, and both are smaller jobs. “We’re always trying to repair rather than replace when possible,” says our owner, Randall Linker. When the compressor itself has failed on an older heat pump, replacement can be the better call.

Did you know?
The U.S. Department of Energy says a heat pump rated 10.3 HSPF for heating gets about three times as much heat per kWh as heat strips. When the strips run all day, you’re paying for that gap.
FAQs About Heat Pump Repair in Indian Trail
Heat Pump Questions, Answered
A heat pump acting strange on a freezing morning isn’t always broken. Plenty of what looks wrong is just defrost, and any good HVAC contractor can tell that apart from a failed part.
The part that failed sets most of the price, so we find it before we talk about cost. A capacitor or contactor is a small repair. A defrost board or reversing valve takes more parts and labor, so it’s a bigger job. A refrigerant leak depends on where it is and how much refrigerant has to go back in. The heat pump’s age and how easy it is to reach play a part too.
It’s worth repairing when the fix is reasonable and the rest of the system is sound. Replacement usually makes more sense when the compressor has failed on an older heat pump or the same leak keeps coming back.
Only when the outdoor unit has stopped working and you need heat until we get there. Emergency heat shuts the heat pump off and runs the electric heat strips by themselves. That keeps the house warm, but the strips use far more power, so it isn’t a setting to leave on for days. If you’ve had to switch to it, tell us when you call.
It freezes solid when frost builds faster than the defrost cycle can clear it. The usual causes are a failed defrost board, a bad outdoor temperature sensor, low refrigerant or a reversing valve that won’t shift. Water dripping off a gutter onto the unit can do it too. Prying at the ice or pouring hot water on it can damage the coil. Leave it, and switch to emergency heat until we’ve looked at it.
That whoosh is usually the reversing valve shifting as a defrost cycle starts or ends, and it’s normal. You might see steam coming off the outdoor unit at the same time. A bang, grinding or screech means something’s wrong, and so does a whoosh that repeats every few minutes. Those point to a valve, fan motor or compressor problem, and they’re worth a call.
Yes, we repair heat pumps all year, since the same outdoor unit does your cooling. In summer the reversing valve sends refrigerant the other way, and the compressor, capacitor and contactor work just as hard as they do in January. A heat pump that cools fine but won’t heat, or heats in July, usually has a reversing valve or control problem.
Most days we can offer same-day service when you call or text (980) 414-5046. We take calls 7 days a week, 6am to 10pm. A cold snap can fill the schedule, so reach out early in the day. If it’s after 10pm, send a text with what’s going on and it’ll be waiting for us at 6am.
Yes. There’s a 1-year labor warranty on the repair we make. Parts carry the manufacturer’s warranty, and terms vary by model.
