Cold air during heating mode
Reversing valve stuck, defrost stuck, or low refrigerant. Heat pumps also blow cooler air than gas heat by design, so we verify actual delivered capacity.

Commercial Heat Pump Repair, Maintenance & Installation
Heat pumps are becoming the default for commercial heating and cooling in California as buildings move away from gas. The East Bay's mild climate is well suited to them, and we service the full range: packaged rooftop heat pumps, split heat pumps, VRF heat pump and heat recovery systems, and water-source heat pumps in multi-tenant buildings.

Diagnostics
Common failures and what they mean
Inverter faults and high-pressure trips
Inverter compressors need clean coils and correct charge. We diagnose from the manufacturer's fault code and confirm with measurements.
One VRF zone too hot, another too cold
Branch selector, EEV or indoor unit sensor issues. We isolate the zone before touching the outdoor unit.
