Having trouble with your heat pump? Climax Energy provides professional diagnosis and repair service in Burnaby. We identify the cause first, explain the repair options, and help you decide whether repair or replacement makes sense for the actual system.
Burnaby
We diagnose and repair heat pump systems throughout Burnaby — Metrotown, Brentwood, Burnaby Heights, South Burnaby, East Burnaby, Capitol Hill and Deer Lake. Burnaby's housing ranges from older detached homes to renovated properties, townhomes and newer multi-level buildings near SkyTrain corridors. System configurations vary: ductless mini-splits are common in condos and newer builds; ducted systems paired with a furnace or air handler appear frequently in older single-family homes. Air distribution, zoning, controls, outdoor-unit condition and the relationship with existing equipment all affect symptoms — and all factor into the diagnosis.
The system runs but indoor temperature doesn't reach setpoint in heating or cooling mode. In Burnaby's older detached homes with limited insulation, a correctly functioning heat pump may still struggle against high heat loss — diagnosis covers both the system and operating conditions, not just the equipment.
A heat pump that won't start 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 — a tripped breaker that trips again after reset needs a deeper diagnosis, not repeated resets.
Frequent start-stop cycles that don't complete a full heating or cooling run often indicate a control fault, a refrigerant pressure issue, or — in larger Burnaby homes — a distribution problem where certain zones reach setpoint quickly while others lag. In multi-level properties, floor-to-floor comfort imbalances can appear as system behaviour problems.
Low airflow in a ducted system may indicate a dirty filter, a failing blower motor, or a duct restriction. Older Burnaby homes with original ductwork may have undersized return capacity that shows up as warm or cool spots rather than an equipment fault. Ductless systems may show weak airflow from a dirty coil or a failed fan motor in the indoor unit.
Light frost on the outdoor coil during heating mode is normal — the system's defrost cycle clears it. Heavy ice that persists after defrost, encases the unit, or appears during cooling mode is not normal and warrants a service call. This may indicate a defrost fault, a refrigerant issue, or restricted airflow around the outdoor unit.
Thermostat and control faults can mimic equipment failures — the system may appear unresponsive when the issue is in wiring or a communication fault between the indoor and outdoor units. Grinding or rattling from the outdoor unit, gurgling inside, or banging on startup each point to different causes and different repair paths.
The symptom alone is not enough to determine the repair. A proper service visit evaluates the equipment, controls, airflow and distribution, and relevant system components before recommending repair or replacement. We do not replace components by assumption — diagnosis comes first.
Do not attempt to add refrigerant, open refrigerant lines, or bypass safety controls. Do not repeatedly reset a breaker that keeps tripping — this can indicate a serious electrical fault. Refrigerant handling requires certification and specialized equipment. If you see or smell burning near the unit, treat it as an electrical issue and have the circuit shut off before calling for service.
Decision Guide
Repair-versus-replacement depends on diagnosis, repair scope, equipment condition, reliability, compatibility and your future HVAC plans — not on the symptom alone.
If replacement is the right path, see our heat pump installation Burnaby page or browse Heat Pump Replacement for an overview of what replacement involves. For ongoing care, see Heat Pump Maintenance.
Common Questions
Yes. We diagnose and repair heat pump systems throughout Burnaby — Metrotown, Brentwood, Burnaby Heights, South Burnaby, East Burnaby, Capitol Hill and Deer Lake — including ductless mini-splits and ducted systems. Burnaby's range of housing types means system configurations and repair considerations vary. We account for the actual setup on each service call.
A heat pump problem can have several causes, so the symptom alone is not enough to determine the repair. Common issues include refrigerant problems, a failed reversing valve, a compressor fault, a defrost system failure, control or thermostat faults, and airflow restrictions. A proper service visit evaluates the equipment, controls, airflow and distribution, and relevant system components before recommending repair or replacement.
Repair-versus-replacement depends on diagnosis, repair scope, equipment condition, reliability, compatibility and your future HVAC plans. A newer heat pump with a single failed component usually makes sense to repair. An older system with a compressor failure or a refrigerant circuit fault on a phased-out refrigerant may be more economical to replace. We give an honest assessment after diagnosis — not before.
The specific fault and component involved, the system type and age, the refrigerant type, and the access conditions at the site all affect repair cost. Some repairs — a capacitor, a sensor — are straightforward. Others — a failed compressor, a refrigerant circuit fault — are more involved. A diagnostic visit identifies the actual cause and scope before any repair work is quoted.
Helpful information includes the heat pump brand, model and age if known, a description of the symptom (what the system is doing or not doing, when it started, any error codes or flashing lights on the indoor or outdoor unit), and whether the issue is in heating mode, cooling mode, or both. Any recent filter changes or service history is also useful context for the technician.
We diagnose the actual fault before recommending any repair — no guesswork, no pressure toward unnecessary replacement.
