Heat Pump Repair in Buford & North Georgia

Heat pump repair gets your system heating or cooling again after a breakdown. Southeast Heating & Cooling repairs all major heat pump brands across Buford and the surrounding communities, starting with a diagnostic that pinpoints what failed.

What does heat pump repair cover?

A heat pump is one system that does two jobs. In summer it moves heat out of your home like an air conditioner. In winter it runs in reverse and pulls heat from the outdoor air into your home. That means a heat pump works nearly year-round, and it has a few parts a standard AC doesn't have: a reversing valve (the part that switches between heating and cooling), a defrost control that melts frost off the outdoor coil, and electric heat strips (backup heaters in the air handler that kick in on the coldest nights).

Heat pump repair covers all of it. We diagnose and fix problems in either mode, on the outdoor unit, the indoor air handler, the thermostat and the wiring between them. We service all major brands. We don't work on window units, geothermal systems, boilers, oil furnaces, mobile-home equipment or commercial units, and we'll tell you that up front rather than waste your time.

How do I know my heat pump needs repair?

Some heat pump behavior looks like a problem but isn't. A short defrost cycle in winter can send cool air through the vents for a few minutes, and steam rising off the outdoor unit during defrost is normal. The signs below are the ones worth a call.

Heating-mode warning signs

• Air from the vents stays cool or lukewarm long after the system starts.
• The outdoor unit is coated in ice or frost that never clears.
• Your thermostat shows "aux" or "emergency heat" all the time and your power bill jumps.
• The system runs constantly but the house never reaches the set temperature.

Cooling-mode warning signs

• Warm air in cooling mode, or weak airflow at the vents.
• Ice on the refrigerant lines or the indoor coil.
• Water around the indoor air handler.
• The outdoor fan doesn't spin, or the unit hums but won't start.

Signs in either mode

• Grinding, buzzing, rattling or a loud hiss.
• Short cycling: the system starts and stops every few minutes.
• A tripped breaker that trips again after you reset it.
• Rooms that used to be comfortable and now aren't.

If you smell burning or the breaker keeps tripping, turn the system off at the thermostat and call us at (770) 265-8308. We try to answer calls 24/7 and aim to respond within 24 hours, though arrival time depends on demand, weather, location and the type of problem.

What usually breaks on a heat pump?

Most of the heat pump repairs our technicians see across Buford, Sugar Hill, Suwanee, Flowery Branch and Dacula come down to a handful of parts.

• Capacitors and contactors. The capacitor gives the compressor and fan motors their starting push; the contactor is the switch that sends them power. Both wear out with heat and age. A humming outdoor unit that won't start is often one of these.
• Defrost control problems. If the defrost board or its sensor fails, the outdoor coil ices over and the system can't pull heat from the air. This is one of the most common winter heat pump calls.
• Reversing valve faults. When the valve sticks or its solenoid fails, the heat pump gets stuck in one mode or won't switch at all.
• Refrigerant leaks. Low refrigerant hurts both heating and cooling. We find and repair the leak rather than just topping off the system.
• Fan and blower motors. Worn bearings, failed motors or a loose blower wheel cause noise, weak airflow and overheating.
• Electric heat strips. A failed strip, sequencer or limit switch means the backup heat isn't there on the coldest nights.
• Thermostat and wiring issues. A miswired or failing thermostat can make a healthy heat pump act broken.

Age and neglect make all of these more likely. Dirty outdoor coils, clogged filters and a blocked condensate drain put extra strain on every part upstream. That's why we point customers toward heat pump maintenance after a repair.

How does Southeast handle a heat pump repair call?

We're a family-owned, locally owned company based at 4582 Atwater Ct STE 8 in Buford, and we've run heat pump calls across our service area since 2022. Here's how a repair visit works.

1. Book by phone, text or online. Our office calls or texts to confirm the appointment. A request isn't final until we confirm it.
2. Diagnostic. The technician tests the system in the mode that's failing, then checks electrical components, refrigerant pressures and temperatures, the defrost cycle, the reversing valve, heat strips, airflow and the drain. Our heat pump diagnostics page explains the visit in detail.
3. Straight options. You get a plain explanation of what failed, why, and a written repair price before any work starts. Nothing gets replaced without your OK.
4. Repair and test. We make the repair, then run the system through a full cycle to confirm it's working in both modes.
5. Follow-through. If a problem is caused by our workmanship, Southeast will return and correct it at no charge.

We don't recommend replacement based on age alone. If the repair cost, installation quality, overall condition and likely upcoming failures point toward a new system, we'll say so and offer a free replacement estimate. If a repair will get you reliable heating and cooling again, that's what we'll recommend. Our 5.0 Google rating across 979 reviews as of September 2026 comes from customers who got the honest answer either way.

What does heat pump repair cost?

Our diagnostic visit is $79. It's typically charged, and it covers the visit and the testing needed to find the cause. Repair prices depend on the part, the brand and the labor involved, so we quote them in writing after diagnosis, never over the phone.

A few things that keep the cost predictable:

• Southeast Family Plan members get 15% off qualifying repairs, priority service and no after-hours charge. The plan is $149 a year for the first system and $109 for each additional system.
• For nonmembers, after-hours pricing varies. We confirm it before dispatch so there are no surprises.
• If the honest answer is replacement, Service Finance options include payment examples from $59 a month for heating and $99 a month for a complete system, with credit approval; see financing terms.
