Heat Pump Repair for Columbus Homes
Heat pumps are the default system across much of the Columbus area, and they behave differently than straight-cool air conditioners. The same outdoor unit produces both heating and cooling by reversing refrigerant flow, which adds components — and failure modes — that a conventional AC does not have.
Many heat pump complaints are really control or changeover problems rather than mechanical failures, and diagnosing them requires knowing which mode the system thinks it is in.

Common symptoms
- Warm air in cooling mode
- System heats when the thermostat is set to cool
- Auxiliary or emergency heat engaging in mild weather
- Loud whoosh or clunk during changeover
- Outdoor unit iced in winter and not defrosting
- Short cycling in shoulder-season weather
Common causes
- Reversing valve or its solenoid failing to shift
- Thermostat configured for the wrong equipment or changeover polarity
- Defrost board or sensor failure
- Low refrigerant charge affecting both modes
- Failed capacitor or contactor
What a professional may inspect
- Reversing valve operation and solenoid energizing
- Thermostat configuration and changeover setting
- Defrost control board sequence and sensors
- Refrigerant pressures in both heating and cooling modes
- Auxiliary heat staging and lockout settings
Safe homeowner checks
- Confirm the thermostat is on COOL, not AUTO or EMERGENCY HEAT
- Replace thermostat batteries
- Clear leaves and pine straw from the outdoor coil
- Make sure the outdoor unit sits above ground level with drainage below it
Safety note: Do not open electrical compartments, handle refrigerant, bypass safety devices, or attempt electrical repairs unless properly qualified.
When to call right away
- Auxiliary electric heat running during summer, which drives extreme power use
- Ice remaining on the outdoor unit for more than a full cycle in cold weather

Why this matters in Columbus
Columbus winters are mild enough that heat pumps carry nearly the entire heating season without much auxiliary heat, so a system leaning on strip heat is a strong signal something is wrong. Summers put the same equipment under sustained cooling load, which means annual run hours here are among the highest for residential HVAC anywhere in Georgia.
