Diagnose heating, cooling, cycling, icing and airflow faults in heat pump systems across West Vancouver's hillside and multi-level homes.
West Vancouver
We diagnose and repair heat pump systems throughout West Vancouver — Ambleside, Dundarave, British Properties, Caulfeild and Horseshoe Bay. Hillside properties, multi-level homes with varied mechanical configurations, and constrained outdoor-unit placements are features we account for on every West Vancouver service call. Each repair starts with proper diagnosis — not assumption.
The system runs but room temperature doesn't reach setpoint in either heating or cooling mode. May indicate a refrigerant issue, a failed reversing valve, a coil problem, or an oversized system short-cycling before completing a proper heat transfer cycle.
A heat pump that won't start at all may have a tripped breaker, a failed capacitor or contactor, a control fault, or a locked-out compressor. We test the electrical supply, control signal and compressor circuit before replacing components.
Frequent start-stop cycles that don't complete a full heating or cooling run may indicate a control fault, a refrigerant pressure issue, or — in larger West Vancouver homes — a distribution problem where main-floor sensors reach setpoint while upper levels lag behind.
Light frost on the outdoor coil during heating mode is normal — the system runs periodic defrost cycles to clear it. Heavy ice build-up that persists, encases the unit, or appears during cooling mode is not normal and warrants a service call.
Low or uneven airflow in ducted systems may indicate a dirty filter, failing blower, or duct restriction. In multi-level homes in British Properties or Caulfeild, airflow imbalance across floors is sometimes a distribution issue rather than an equipment fault. Control issues may point to a thermostat, wiring, or communication fault between indoor and outdoor units.
Grinding or rattling from the outdoor unit may indicate a failing fan motor or compressor bearing. Gurgling inside the indoor unit can suggest a refrigerant flow issue. Banging on startup sometimes points to a compressor mounting or liquid slugging problem. Each has a different cause and repair path.
West Vancouver's coastal winters bring damp, mild-to-cool conditions that are within the normal operating range of most heat pumps. Light frost forming on the outdoor coil during heating operation is expected — the system's defrost cycle clears it automatically. If you see heavy ice that the system hasn't cleared after a full defrost cycle, ice forming during mild above-freezing weather, or ice during summer cooling mode, have a technician assess the system. These patterns suggest a defrost fault, refrigerant issue, or airflow restriction rather than normal cold-weather operation.
If you suspect a refrigerant issue — reduced heating or cooling capacity, ice on the coil during normal conditions, or hissing near the outdoor unit — do not attempt to add refrigerant, open refrigerant lines, or bypass safety controls. Refrigerant handling requires certification and specialized equipment. A licensed technician can perform a proper leak check, repair, and refrigerant charge.
Decision Guide
The right path depends on what's failed, the system's age and condition, and how repair cost compares to replacement.
If replacement is the right path, see our heat pump installation West Vancouver page or browse Heat Pump Replacement for an overview of what replacement involves.
Common Questions
Yes. We diagnose and repair heat pump systems across West Vancouver — Ambleside, Dundarave, British Properties, Caulfeild and Horseshoe Bay — including ductless mini-splits and ducted systems. West Vancouver's hillside sites and varied mechanical configurations are accounted for in how we plan each service call.
Common causes include a refrigerant issue reducing heat exchange, a failed reversing valve that prevents the system from switching to heating mode, a defrost system fault leaving the outdoor coil blocked with ice, a failed compressor, or a control fault preventing the system from operating correctly. Diagnosis determines the actual cause — several of these present with similar symptoms.
Light frost on the outdoor coil is normal during heating operation — the unit periodically runs a defrost cycle to clear it. What isn't normal is a thick build-up of ice that encases the unit, persists for extended periods, or appears during cooling mode. Heavy icing that doesn't clear on its own may indicate a defrost system fault, low refrigerant charge, or an airflow restriction, and warrants a service call.
The right call depends on the diagnosis, equipment age and what the repair costs relative to a new system. A newer heat pump with a single failed component — capacitor, reversing valve, control board — usually warrants repair. An older system with a failed compressor or a refrigerant circuit fault may be more economical to replace, particularly if the system is also approaching end-of-life. We give an honest assessment after diagnosis.
The component that needs repair or replacement, system type and age, refrigerant type, and site access all affect cost. On West Vancouver hillside properties, outdoor-unit access can sometimes add complexity to a service call. A diagnostic visit establishes the actual cause and scope before any repair work is quoted.
We diagnose the actual fault before recommending any repair — no guesswork, no pressure toward unnecessary replacement.
