A heat pump tripping the breaker once might be a power-quality blip. Tripping twice in a week is a signal something is wrong inside the unit. Here are the six most common causes and which ones require licensed gas or electrical repair.

Failing start or run capacitor draws excessive current at startup → breaker trips. $250-$400 to diagnose and replace. Most common cause we see.
Internal short in the compressor windings or a seized rotor draws maximum amperage instantly. $2,500-$5,500 to replace compressor — at 12+ years often better to replace unit.
Bearings fail, fan stalls, current spikes. $300-$600 to replace fan motor.

📞 (604) 359-1081 Request a quoteOriginal installer used a 30A breaker on a 40A unit, or a 15-year-old breaker has weakened. Licensed electrician replaces breaker, $200-$350. CANRO partners with licensed electricians for these jobs.
Rodent damage, water intrusion, or vibration wear shorts 24V wiring. $180-$320 to trace and repair.
Some units trip the breaker on extreme high-pressure fault rather than internal control. Indicates a coil airflow or refrigerant issue.
Do not reset the breaker more than twice. Persistent trips indicate a hazardous fault — call CANRO same day. Leaving a tripping unit can damage windings, melt insulation, or start a fire.
CANRO arrives with multimeter and clamp-on amp probe. We measure inrush current, capacitance, winding resistance, and refrigerant pressure. Diagnostic + minor repair typically same visit.

Below is a CANRO technician's perspective on heat pumps as they apply in Metro Vancouver: what to look for, what to avoid, and what to expect. A cold-climate heat pump in Metro Vancouver delivers 2-4 units of heat per unit of electricity — meaning 200-400% effective efficiency vs 95-98% for the best gas furnace. Vancouver's mild winters (rare lows below -5°C) are ideal heat-pump territory.
Vancouver's mild winters (average lows above -5°C and rare deep cold snaps) shape equipment selection differently than colder Canadian cities. CANRO has worked with heat pump systems across Metro Vancouver since 1999, including installations and service calls in Maple Ridge, Ranch Park, Edmonds and Yaletown.
Sizing. Heat-pump sizing balances heating capacity at design temperature (often -10°C in Metro Van) against cooling load. Variable-capacity units handle both ends well — over-sizing for heating causes summer humidity problems.
Lifespan. A modern heat pump installed by a qualified contractor typically lasts 15-20 years. Annual maintenance, regular filter changes, and keeping the outdoor coil clear of leaves and debris all extend service life.
Warning signs. Heat-pump issues include short-cycling, refrigerant-charge problems (low cooling capacity), defrost-cycle faults, communicating-system errors, and ECM motor failures at 12+ years.
Yes — every heat pump is also a fully functioning air conditioner. One unit replaces both a furnace and an A/C, saves floor space, and qualifies for rebates that a separate A/C alone would not.
SEER measures cooling efficiency (higher is better, 16-22 typical); HSPF and the newer HSPF2 measure heating efficiency. For Vancouver, look for HSPF2 above 9.0 — that's the threshold for premium cold-climate performance and most rebate programs.
Current heat-pump rebates can total $11,000+ for eligible Vancouver homeowners: up to $6,000 from CleanBC, up to $5,000 from federal Greener Homes, plus income-qualified top-ups. CANRO is a registered contractor and handles the paperwork end-to-end.
Yes. Modern cold-climate heat pumps from Mitsubishi (H2i), Daikin (Aurora), Carrier (Greenspeed) and Lennox (XP25) maintain rated heating capacity down to -15°C and continue producing heat (at reduced capacity) down to -25°C — far colder than Metro Vancouver ever gets.
If you already have ductwork from a furnace, a ducted central heat pump is usually the better choice for whole-home comfort. Ductless mini-splits are ideal for additions, basement suites, garage conversions, and homes without ducts (radiant-heated houses).
A whole-home ducted heat pump installation in Metro Vancouver typically costs $13,000-$22,000 before rebates. After stacking BC Hydro + FortisBC + federal rebates, eligible homeowners can see net costs of $5,000-$11,000.
