Commercial Heat Pump Repair in Orange, CA

Expert diagnostics for complex commercial systems

Your facility relies on precise, predictable heat pump performance. We use advanced instrumentation, data logging, and manufacturer procedures to pinpoint root causes—whether the issue is airflow imbalance, refrigerant charge error, electrical faults, control programming, or building load miscalculations. Our goal is simple: fix it right, verify, and extend equipment life.

• Rooftop packaged heat pumps: economizer integration, coil restoration, compressor and fan motor repair
• VRF or VRV heat pump systems: inverter boards, thermistors, communication errors, oil return issues
• Ductless mini-splits: indoor head failures, condensate drainage, defrost cycle problems
• Split heat pump systems: reversing valves, TXV/EEV performance, heat strip coordination
• Controls and BMS: sensor calibration, staging, scheduling, and fault-code resolution

We combine field data, engineering know-how, and factory training from Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China) to deliver reliable, repeatable outcomes across most commercial applications.

Healthy indoor air is our mission

Comfort is only part of the story. We engineer repairs that support healthier air: restored airflow, clean heat exchange surfaces, correct defrost logic, sealed duct transitions, and safe refrigerant management. The result is steadier temperatures, reduced moisture problems, and better occupant well-being—often with lower energy spend.

What we fix most often

• Short cycling, no heat, or no cooling in heat pump mode
• High head pressure or low suction due to airflow or charge issues
• Icing and defrost failures impacting winter performance
• Electrical faults: contactors, boards, sensors, and communication
• Noisy operation: bearings, belts, fan imbalance, or debris
• Leaking condensate or water intrusion around rooftops
• Poor comfort across zones, staging or control misconfiguration

Every repair includes verification steps to ensure your system meets load, airflow, and control requirements for your occupancy and hours of operation.

Industries and facilities we serve

• Office and co-working spaces
• Retail and restaurants
