A heat pump that is running but not warming your Vancouver home is one of the most common service calls we get. Here are the 10 things we ask homeowners to check before we drive out — about half of these are DIY fixes that save you a service-call fee.

Sounds obvious — and yet it is the #1 false alarm. AUTO mode in shoulder season can leave the system in cool mode when you actually want heat. Switch to HEAT explicitly.
A clogged filter restricts airflow and triggers an over-temperature safety lockout. Replace or wash. If the unit restarts after 10-20 minutes, this was the issue.
Walk outside. Is the fan spinning? Are there any ice buildups blocking the coil? Listen for the compressor hum.

Heat pump trips usually mean overcurrent, short-cycle, or a capacitor issue. Reset once. If it trips again immediately, stop and call.
On a dual-fuel system, if the gas furnace is running but heat pump is not, the changeover balance point may be misconfigured. Easy CANRO adjustment.
Clicking sound followed by silence usually means start capacitor failure. Common, easy fix — call CANRO, $250-$400 parts and labour typical.
Outdoor unit has a service disconnect within 3 feet — confirm it is in the ON position. Squirrels and landscapers occasionally bump it.
Low battery causes weird behaviours — backup-heat-only mode, false cool calls. Replace and re-program schedule.
A faint chemical or "sweet" odour near the indoor unit may indicate a refrigerant leak — this is the one item where you stop troubleshooting and call us immediately.
If the DIY checks do not solve it, CANRO offers same-day diagnostic in Metro Vancouver. Typical diagnostic fee $89-$129, applied against repair cost if you proceed.
