Accolade Heating provides heat pump repair in Surrey, BC — systems not heating in cold weather, reversing valve faults, error codes, refrigerant issues, defrost board failures, and ductless mini-split faults. TECA Quality First and Red Seal certified, same-day service available.
Heat pumps have fault modes that differ from furnaces and air conditioners. These are the most common repair scenarios our Surrey technicians diagnose.
| Component | Common Fault | Our Approach |
|---|---|---|
| Reversing Valve | Stuck in heating or cooling mode — cannot switch between seasons | Test valve with thermostat calls; replace solenoid or full valve if stuck |
| Defrost Control Board | Faulty timing or sensor — coil ices over or system stuck in defrost | Test defrost termination sensor and board logic; replace as needed |
| Refrigerant Charge | Low from slow leak — first symptom is loss of heating in cold weather | Leak search, repair, recover and recharge to factory spec |
| Compressor | Hard-start, seized, or electrical failure — no heating or cooling | Test amp draw, windings, capacitor; repair or quote replacement |
| Ambient Temp Sensor | Incorrect outdoor reading causes improper defrost or lockout | Test resistance vs temperature curve; replace if out of spec |
| Electronic Expansion Valve | Stuck open or closed — erratic refrigerant flow | Test valve operation electrically and mechanically; replace if failed |
| Capacitor | Degraded — compressor or fan motor won't start reliably | Measure capacitance; replace with OEM-spec capacitor |
| Communication Board | E1/E6 error — indoor and outdoor units lose communication | Check wiring, test voltage, replace board or module |
Before calling, note any error codes displayed. For ducted systems, check whether emergency heat is running — this information speeds diagnosis.
Our TECA-certified technician arrives with heat pump diagnostic tools, refrigerant gauges, and common replacement parts for your brand.
We test refrigerant pressures, electrical components, defrost operation, reversing valve function, and sensor calibration to find the root cause.
Clear itemised quote before any work begins. Repair completed and tested in both heating and cooling mode before we leave.
Heat pumps include components unique to dual-mode operation — reversing valves, defrost control boards, and electronic expansion valves are not found in furnaces or air conditioners. Diagnosing them correctly requires specific TECA-certified training and test equipment beyond basic HVAC service.
