Heat Pump Repair in Woodstock, GA
Heat pump repair is different from standard AC or furnace repair. Different components fail, different diagnostic procedures apply, and most generalist HVAC techs misdiagnose heat pumps regularly. Evenflow Heating & Air technicians specialize in heat pump systems across Woodstock and Cherokee County, including reversing valves, defrost boards, and dual fuel controls.

Why Heat Pump Repair Needs Specialized Knowledge
A heat pump is essentially an air conditioner that runs in reverse during winter. Sounds simple, but the components that handle the reversal (reversing valves, defrost boards, auxiliary heat strips, dual fuel controls) introduce failure modes no traditional AC or furnace ever experiences. A tech who treats a heat pump like a standard AC will miss the actual problem nine times out of ten.
We invest in heat pump-specific training and brand-specific diagnostic tools because heat pumps are increasingly common in Cherokee County and need technicians who actually understand them. That’s the difference between a real fix and a band-aid that fails again the next time the temperature drops.
Heat Pump Problems We Fix Every Day in Cherokee County
We focus entirely on getting your cooling system right. Pick the service you need below to learn more, or call us if you are not sure where to start.
Heat Pump Not Heating
Could be a stuck reversing valve, failed defrost board, weak refrigerant charge, or seized outdoor fan motor. Each gets a different diagnostic approach.
Heat Pump Blowing Cold Air in Heat Mode
Reversing valve solenoid failure, low refrigerant charge, or auxiliary heat strips that failed to engage when needed. We trace the actual cause through electrical and refrigerant testing.
Outdoor Unit Frozen Solid
Defrost cycle failure, failed sensor, blocked airflow, or low refrigerant. Normal heat pump operation includes brief defrost cycles. Solid ice accumulation signals real problems.
Heat Pump Short Cycling
Refrigerant issues, electrical faults, oversized equipment, or failing contactors causing rapid on-off cycles. Each startup stresses the compressor severely.
Heat Pump Leaking Water Inside
During heating mode, the indoor coil acts like a furnace and shouldn't leak. Water indoors usually means a refrigerant leak that's causing the indoor coil to ice and melt repeatedly.
Auxiliary Heat Running Constantly
Emergency heat strips running nonstop means the heat pump isn't doing its job. Could be refrigerant loss, compressor failure, or reversing valve issues, all of which spike your electric bill fast.

Your technician arrives with reversing valves, defrost boards, contactors, capacitors, sensors, and refrigerant on the truck.
Full Heat Pump-Specific Diagnostic.
We test reversing valve operation in both modes, verify defrost cycle function, measure refrigerant pressures, check auxiliary heat strip operation, and inspect electrical components.
Flat-Rate Written Quote.
Every repair priced in writing before work begins. Reversing valve replacement, defrost board swap, refrigerant work, or component repair, you see the cost upfront.
Efficient Repair with Mode Verification
Many heat pump repairs can be completed in one visit when scheduling and parts availability allow. Before we leave, we test heating, cooling, and defrost operation to confirm the system is working correctly.
Heat Pump Repair Costs in Woodstock
Heat pump repair pricing in Cherokee County depends on the specific fault. Realistic ranges:
Capacitor replacement runs $200 to $400. Contactor replacement $250 to $450. Defrost board replacement $400 to $700. Reversing valve replacement $800 to $1,500 (this is the big one). Outdoor fan motor replacement $400 to $800. Refrigerant leak detection and repair $400 to $1,500. Compressor replacement $1,800 to $3,500, which usually triggers a repair-versus-replace conversation on older systems.
We provide every quote in writing before work begins.
When to Call vs. When to Wait
Some AC problems can wait until Monday. Others should not. Here's the difference.
Call now if:
- Your heat pump won't heat in cold weather
- Your outdoor unit is frozen solid
- Your auxiliary heat strips are running constantly (you'll see "Aux Heat" or "Em Heat" on your thermostat), or the system is making loud noises in heat mode.
Schedule within a week if:
- Heating cycles feel weaker
- Some rooms stay cool
- You notice the system runs longer than usual, or you hear minor sounds during mode changes.
Our technicians diagnose every AC issue using superheat and subcooling measurements, static pressure readings, and electrical performance testing. No guesswork, no parts cannon, no upsell pressure.

Frequently Asked Questions
Most common causes are a stuck reversing valve that didn’t shift from cooling to heating mode, a low refrigerant charge limiting heat output, or auxiliary heat strips that failed to engage during cold weather. Sometimes the thermostat is set incorrectly. We check all of these systematically.
Some frost on the outdoor coil during cold weather is normal. Solid ice accumulation means the defrost cycle isn’t working, which typically points to a failed defrost board, failed defrost sensor, or refrigerant problems. The unit will run inefficiently or stop heating entirely until it’s repaired.
If the system is under 10 years old and the repair is under 30 percent of replacement cost, repair almost always wins. Over 12 years old with a major repair like a reversing valve or compressor, replacement usually pays off within 3 to 5 years from efficiency gains.
Auxiliary heat is supposed to supplement your heat pump during very cold weather, not replace it. Constant aux heat usage means the heat pump isn’t performing, which usually points to refrigerant loss, a failed compressor, or reversing valve problems. Your electric bill will spike fast if this continues.
