What We Service
A Quantum heat pump draws ambient air via a fan over the evaporator coil. Key service focus: fan & coil, compressor, sensor & controller, valves, anode, relief / safety devices, drainage / condensate.
Common Issues with Quantum Heat Pumps
Some Quantum owners report their units running all night, then cutting out of hot water — possible refrigerant loss or thermostat drift. Here's what we fix.
No hot water / lukewarm
Sensor/thermostat failure, compressor not starting, refrigerant leak, restricted airflow, timer or supply issue. We check panel, wiring, sensor resistances, and airflow around coil.
PTR / Relief valve dripping
High pressure/temperature, worn valve, blocked drainage. We test relief, measure pressure, and replace the valve if required.
Frequent running / never stops
Ambient too cold, coil dirty/iced, control or sensor fault. We clean the coil, confirm defrost mode, and verify controller settings.
Noise / vibration
Fan bearing wear, debris, loose mounting, or compressor strain. We inspect the fan, tighten hardware, and clear debris.
Fault / error codes
Overtemp, overpressure, sensor or communication fault. We read codes, trace sensor wiring, and replace faulty parts.
Reduced efficiency / high power use
Dirty coil, scale, partial failure, booster overuse. We flush the coil, descale, and check heating cycle efficiency.

Why use a dual-trade team?
Heat pumps are 50% plumbing and 50% electrical/refrigeration. Standard plumbers often can't legally test the sensors, PCB, or compressor wiring. Standard electricians can't legally replace the valves or tank.
Todd's Plumbing & Electrical sends technicians qualified in both, meaning we diagnose the whole system and fix it in one visit.
