Heat pumps provide both heating and cooling — when they fail, they take both functions offline. We connect homeowners across Gibsonville and Guilford County with local contractors who diagnose and repair heat pump systems year-round.

Gibsonville sits on the Guilford-Alamance county line east of Greensboro, a smaller town whose older core grew up along the historic rail line that also shaped neighboring Burlington and Graham, with more recent residential development filling in between the historic downtown and the busier Burlington and Greensboro corridors. Its housing stock is a mix of early-1900s frame homes near downtown and newer subdivisions built as the town has grown along with the rest of the eastern Triad. Guilford and Alamance counties share the same rolling clay-soil Piedmont terrain, with hot, humid summers and occasional winter ice storms typical of the region. Because Gibsonville sits directly on the county line, homes on opposite sides of town can fall under different jurisdictions while facing identical climate and soil conditions, which is one reason equipment recommendations here are based on the specific home rather than a one-size answer for the town.

Heat Pump Problems We Fix

Common heat pump failures include reversing valve problems that prevent the system from switching between heating and cooling modes, refrigerant leaks, defrost board failures that cause ice buildup on the outdoor unit, compressor issues, and auxiliary heat problems. Heat pump diagnostics require specialized knowledge of the refrigerant cycle in both directions.

System runs constantly but never quite reaches the set temperature

This often points to a refrigerant or airflow issue rather than a thermostat problem — a technician can check charge levels and airflow before assuming the system itself is undersized.

Outdoor unit is covered in ice, even when it's not especially cold out

Some frost during a normal defrost cycle is expected, but heavy ongoing ice buildup usually means the defrost cycle isn't completing correctly or airflow is restricted.

Noticeably higher electric bills with no change in usage habits

A heat pump working harder than it should to hit the same comfort level is a common early sign of a developing mechanical issue, often before anything sounds or feels obviously wrong.

Heat Pump vs. Furnace in Piedmont Triad

In Piedmont Triad's climate, heat pumps are efficient down to certain outdoor temperatures, after which auxiliary or emergency heat takes over. If your heat pump is running but not keeping up in cold weather, the issue may be with the auxiliary heat source rather than the heat pump itself. The full system gets checked to confirm.

Rooms that have always been colder than the rest of the house. That is normally duct sizing, air balance, or insulation, and a repaired heat pump will heat those rooms the same way it did before.
A system that was undersized for the house at installation. A repair restores the capacity the equipment was built for, not more.
Winter electricity costs caused by auxiliary heat operating as intended in cold weather. Lowering that is a thermostat-settings and balance-point discussion, not a repair.
Duct leakage in an unconditioned attic or crawlspace, which loses conditioned air no matter how well the equipment itself performs.
Summer humidity complaints traced to an oversized system that short-cycles. Component repair does not change how the system was sized.

Frequently Asked Questions

My heat pump is running but blowing cool air when it should be heating. What's wrong?

This is a common heat pump complaint, and it has a few possible causes: a stuck reversing valve that won't switch the system into heating mode, low refrigerant, or the system relying on auxiliary heat that isn't kicking in. It doesn't automatically mean the compressor has failed — we test the reversing valve and refrigerant circuit before assuming the worst.

What does heat pump repair usually cost?

It varies by component. A defrost board or capacitor repair is a modest job; a reversing valve or compressor issue is more involved because of the refrigerant work required. We diagnose the actual fault first and give you a written estimate before any repair, so the cost reflects the real problem rather than a guess.

Should I repair my heat pump or replace the whole system?

If the unit is relatively young and the fault is a single part — a capacitor, contactor, or defrost board — repair is almost always the right call. A failed compressor, especially on a system already past 10-12 years old, is where replacement starts making more sense, since compressor work is expensive relative to the value left in an aging unit. We lay out both paths honestly.

How often does a heat pump need maintenance, and why does it matter more than for a furnace?

We recommend twice-a-year service for heat pumps — once before cooling season and once before heating season — since the same unit runs year-round in both modes. In Piedmont Triad, winter freezes put real stress on the outdoor unit's defrost cycle, and neglected units are the ones we most often see with ice buildup or reversing valve failures.

What is the most common problem with heat pumps?

Across service calls the most frequent failures are electrical and control-side rather than catastrophic: capacitors, contactors, defrost boards, and defrost sensors. Reversing valve and compressor failures get the most attention because they are expensive, but they are far less common than the smaller parts that stop a unit from switching modes or completing a defrost cycle. That distinction matters for what you should expect — a heat pump that has stopped heating is more likely to need a modest part than a new system.

At what outdoor temperature does a heat pump switch to auxiliary or emergency heat?

There is no single temperature. It depends on the balance point for your home, which is the outdoor temperature at which the heat pump's output stops matching the building's heat loss. On many systems that falls somewhere in the 30s Fahrenheit, but it is a function of the equipment, the insulation, and how the thermostat is programmed rather than a fixed number. Auxiliary heat engaging during genuinely cold weather is normal. Auxiliary heat running in mild weather is not, and that usually points to a control, sensor, or refrigerant charge problem worth diagnosing.
