Burnaby's dense condo and townhouse stock makes strata-specific service experience essential.

A significant portion of Burnaby's heat pump stock is in strata buildings — condos and townhouses where outdoor unit access requires coordination and noise-related service calls are common. Condo mini-split units in humid coastal conditions develop condensate drain issues frequently. For strata repairs, confirm your contractor is familiar with strata access procedures and building bylaw requirements around service windows.

Most common Burnaby repair issues

1.Condensate drain clog (indoor water leak in condos)
2.Strata access and noise-related service complications
3.Fan motor failure causing noise complaints

Before You Call a Technician

Run through these steps first. They resolve ~20% of service calls and save you a diagnostic fee.

Check the breaker

Find the dedicated heat pump breaker in your panel. Flip it fully OFF, then ON. If it trips immediately again, stop — call an electrician.

Check thermostat settings

Confirm it's set to HEAT (not COOL or FAN), the set temperature is above room temperature, and batteries are fresh. Many "no heat" calls are thermostat mode errors.

Check the filter

Ductless: pop open the indoor unit cover and check the filter. Ducted: find your air handler filter. A fully clogged filter causes safety shutdown. Replace or wash it.

Clear the outdoor unit

Remove snow, leaves, or debris within 30cm on the sides and 60cm at the front (discharge direction). Check that the unit isn't buried in snow.

Check for error codes

Most modern units display error codes on the indoor unit display or blink a fault pattern. Note the code before calling — it tells the technician what to bring.

For an iced outdoor unit

Switch to FAN-ONLY mode for 20–30 minutes to let it defrost. If it re-ices within an hour of defrosting, you have a defrost system issue.

Check for recent power outages

Some units require a manual reset after a power interruption. Turn the unit off at the thermostat or remote, wait 30 seconds, turn back on.

Symptom Guide

Common heat pump symptoms, likely causes, and what to try before calling.

Blowing cold air in heat mode

Medium priority

Likely Cause

Active defrost cycle (normal), stuck reversing valve, or low refrigerant

Try First

Wait 5–10 minutes — defrost cycles are normal and temporary

Call If...

Cold air continues after 10 min, or happens repeatedly throughout the day

Outdoor unit heavily iced over

High priority

Likely Cause

Defrost board/sensor failure, blocked airflow, or low refrigerant

Try First

Switch to fan-only for 20–30 min to defrost. Clear debris around unit.

Call If...

Unit re-ices within an hour, or ice covers the entire coil and fan

Mini split dripping water indoors

Medium priority

Likely Cause

Clogged condensate drain — common in humid BC climates

Try First

Flush condensate drain line with diluted vinegar. Check for blockage at drain outlet.

Call If...

Water is pooling, not just dripping. Mold visible in the unit.

Unit not turning on at all

High priority

Likely Cause

Tripped breaker, failed capacitor, communication fault, or burned contactor

Try First

Reset breaker once. Check thermostat batteries. Try unplugging remote and re-pairing.

Call If...

Breaker trips again, or unit still won't start after breaker reset

Grinding or squealing noise

Medium priority

Likely Cause

Fan motor bearing wear, loose fan blade, or debris in outdoor unit

Try First

Inspect outdoor unit for sticks, leaves, or debris caught in the fan. Turn unit off first.

Call If...

Noise persists after clearing debris, or you hear grinding from the compressor area

Short cycling (frequent on/off)

Medium priority

Likely Cause

Oversized unit, low refrigerant, dirty filter, or refrigerant metering issue

Try First

Check and clean the filter. Ensure all registers and vents are open.

Call If...

More than 4-6 short cycles per hour after filter is clean

Runs constantly but can't reach set temperature

Low priority

Likely Cause

Below unit's rated operating temperature, low refrigerant, poor insulation, or undersized system

Try First

Check outdoor temp vs unit's rated minimum. Seal obvious drafts. Check filter.

Call If...

Outdoor temp is within unit's range but performance is still poor

Musty or mold smell

Low priority

Likely Cause

Dirty evaporator coil, mold in condensate pan, or clogged drain

Try First

Clean the indoor unit filter. Run unit on cooling mode to flush condensate.

Call If...

Smell persists after filter cleaning. Visible mold on the indoor unit.

Backup heat not activating (hybrid system)

High priority

Likely Cause

Thermostat changeover threshold setting, failed gas valve, or communication fault

Try First

Check thermostat for manual override to backup heat mode.

Call If...

Cannot manually switch to backup heat — this is an emergency in cold weather

Defrost board or sensor	$350–$650	Critical for BC winters. Usually covered under manufacturer warranty.
Control board replacement	$900–$1,800	High variation by brand. Get OEM board — aftermarket boards cause reliability issues.
Condensate drain service	$150–$350	DIY possible: flush with diluted vinegar. Call if fully blocked or frozen.
Reversing valve	$600–$1,200	Stuck valve = won't switch between heating and cooling. Labor-intensive.
