Don’t Ignore These Warning Signs
Your heat pump works hard year-round — heating your home through BC’s damp winters and cooling it during increasingly hot summers. Like any mechanical system, it gives you warning signs before a small issue becomes an expensive breakdown.
Here are five signs Victoria and Vancouver Island homeowners should watch for — and what to do about each one.
1. Strange Noises During Operation
A healthy heat pump hums quietly. If you’re hearing grinding, squealing, rattling, or banging, something’s wrong.
Grinding usually means a motor bearing is failing. Squealing points to a belt issue or refrigerant pressure problem. Rattling often indicates loose hardware or debris in the outdoor unit. Banging could be a failing compressor — the most expensive component to replace.
What to do: Turn off the system and call for a repair. Running a heat pump with failing bearings or a loose compressor can cause cascading damage.
2. Your Energy Bills Are Climbing
Heat pumps are efficient by design. If your BC Hydro bill has jumped 20–30% without a change in usage, your heat pump is working harder than it should.
Common culprits include dirty filters (the easiest fix), low refrigerant from a slow leak, a failing reversing valve, or iced-over coils. In Victoria’s mild climate, icing should be rare — if your outdoor unit is regularly frosting up, that’s a red flag.
What to do: Start with the basics — check and replace your filter. If bills stay high, book a diagnostic appointment. A refrigerant leak caught early is a $300 fix; caught late, it’s a $3,000 compressor replacement.
3. Uneven Heating or Cold Spots
If some rooms are comfortable while others stay cold, the issue might be your heat pump, your ductwork, or both.
Heat pump causes: Low refrigerant, a failing compressor, or a reversing valve stuck in cooling mode. Ductwork causes: Leaky ducts, disconnected runs, or undersized supply lines. Homes in Langford and the Westshore built in the 1990s are especially prone to ductwork issues.
If you have a ductless mini-split, uneven heating usually points to an undersized unit or a refrigerant issue rather than ductwork.
What to do: A technician can do a room-by-room temperature check and duct pressure test to pinpoint the source. Often, a simple duct repair or system rebalance solves it.
4. The System Short-Cycles
Short-cycling means your heat pump turns on, runs for a few minutes, shuts off, then starts again — over and over. This wastes energy and wears out the compressor prematurely.
Causes include an oversized system (common in older installs), a faulty thermostat, low refrigerant, or an electrical issue. If your heat pump was installed more than 10 years ago and short-cycles frequently, it may have been incorrectly sized for your home from the start.
What to do: Have a technician diagnose the cycle pattern. If it’s a thermostat or electrical issue, the fix is straightforward. If the unit is oversized, you may want to discuss replacement options — a correctly sized system will be more comfortable and cost less to run.
5. The System Is 15+ Years Old
Heat pumps typically last 15–20 years with proper maintenance. If yours is approaching that range and you’re seeing any of the signs above, it’s time to seriously consider replacement rather than repair.
Modern heat pumps are dramatically more efficient than units from 2010 or earlier. A new system can cut your heating costs by 30–50%, and with BC rebates covering $6,000–$11,000 of the installation cost, the payback period is shorter than ever.
