Heat Pump Repair
Diagnostics and repair for central heat pumps and mini-splits.
Heat pumps work hard in Iowa — heating in winter and cooling in summer. When one mode fails (or both), you need a technician who understands reversing valves, defrost cycles, and inverter mini-split controls. GERARDO HVAC LLC repairs central and ductless heat pumps across Fort Dodge, Webster City, Humboldt, and Eagle Grove, Iowa.
Signs You Need Heat Pump Repair
- Heat pump runs in summer but not in winter (or vice versa)
- Outdoor unit iced over and not defrosting
- Constantly stuck in emergency / auxiliary heat
- Indoor mini-split head leaking water
- Loud humming or vibration from the outdoor unit
- Error codes on the mini-split display
How I Approach Heat Pump Repair
Heat pump diagnostics require checking refrigerant in both modes, verifying reversing valve operation, testing defrost board logic, and confirming proper airflow. Mini-splits add inverter board and communication-line testing. I bring the right tools for both.
What's Included
- Reversing valve testing and replacement
- Defrost cycle and outdoor sensor diagnostics
- Refrigerant pressure and leak testing

Heat Pump Repair — FAQs
Why is my heat pump iced over in winter?
Heat pumps frost up normally and run a defrost cycle every 30-90 minutes. If it stays iced over, the defrost board, sensor, or reversing valve is the usual cause — all repairable.
Do you repair mini-split systems?
Yes — single-zone and multi-zone ductless mini-splits from Mitsubishi, Daikin, LG, Fujitsu, Gree, MRCool, and similar brands.
My heat pump runs constantly on emergency heat — what's wrong?
Usually a refrigerant, defrost-board, or thermostat-wiring issue. The system is heating with expensive electric strips because the heat pump can't keep up. Worth diagnosing right away — it's costing you money every hour.
Can you handle warranty parts?
Yes. Bring your model and serial numbers and I'll help confirm warranty coverage on the failed part before ordering.
