Upfront pricing and a straight answer on repair vs. replace — no scare tactics, no pressure.
We repair every major heat pump brand and Mitsubishi Electric ductless systems with expert care.
Catching these early prevents a small fix from becoming a comfort emergency or a bigger bill.
Weak or no warm air in heat mode often means low refrigerant, a stuck reversing valve, or a compressor issue.
If it won't cool in summer, the cause is usually refrigerant, a dirty coil, or a failing component.
Heavy ice the defrost cycle can't clear points to airflow, refrigerant, or defrost-control problems.
Turning on and off every few minutes strains the compressor and signals a control or sizing fault.
Grinding, screeching, buzzing, or rattling means worn or loose parts — cheaper to fix early.
A spike with no change in usage usually means lost efficiency from a developing problem.
Cold air in heat mode (or warm in cool mode) often points to a failing reversing valve.
A system that's completely dead can be a tripped breaker, failed capacitor, thermostat, or control board.

Weak or no heating/cooling usually points to low refrigerant, a failing compressor or capacitor, a stuck reversing valve, a dirty coil, or a thermostat issue. We diagnose the exact cause and fix it right. Call (859) 242-4663 for fast repair in Cincinnati.
Some frost is normal in winter, but heavy ice the defrost cycle can't clear signals a problem — often low refrigerant, restricted airflow, or a failing defrost control. Turn the system off and call GC right away to prevent compressor damage.
Yes. HVAC problems don't follow business hours. If your heat pump fails during extreme heat or cold, we offer same-day and emergency repair with fully stocked trucks, so most repairs are completed in a single visit. Call (859) 242-4663.
Cost depends on the part and the problem, from a minor capacitor or thermostat fix to a refrigerant leak or compressor repair. We provide upfront pricing before any work begins — no surprises. If a repair isn't the smart long-term choice, we'll tell you honestly.
If your heat pump is under about 10 years old and the repair is reasonable, repair usually makes sense. If it's 12–15+ years old, needs frequent or major repairs, or uses R-22 refrigerant, replacement may save more over time. We give honest advice with no pressure.
