Heat pump not heating or cooling? AceComfort's certified technicians diagnose and repair all types of heat pumps across Metro Vancouver — including ductless mini-splits, central ducted systems, and water source units — with same-day service available.
Heat pumps are highly efficient and generally reliable — but when they fail, they affect both your heating and cooling at once. AceComfort's technicians are certified on Mitsubishi, Daikin, Carrier, Lennox, and all major heat pump brands, with advanced diagnostic tools and a comprehensive parts inventory on every service vehicle.
Whether your ductless mini-split is blinking an error code, your central heat pump has stopped heating, or your water source unit in a strata building has failed — we diagnose the exact problem and give you a clear repair estimate before any work begins. No guesswork, no overselling parts that don't need replacing.
We also service heat pumps under manufacturer warranty and can coordinate with manufacturers on warranty claims for eligible repairs.

(604) 636-3939A heat pump that runs but doesn't condition the air may have a refrigerant issue, a faulty reversing valve, or a failed compressor. We'll determine the exact cause and advise on the most cost-effective repair path.
Modern heat pumps communicate faults through error codes. We read and interpret manufacturer-specific codes to identify the exact component that needs attention — saving time and avoiding misdiagnosis.
Some frost on the outdoor unit in cold weather is normal — your heat pump has a defrost cycle for this. Heavy ice accumulation that doesn't clear, however, points to a defrost control issue, refrigerant problem, or airflow restriction that needs repair.
Refrigerant doesn't get used up — if levels are low, there's a leak somewhere in the system. We locate and repair the leak, then recharge to factory specifications. A top-up without fixing the leak is a temporary measure that will fail again.
A heat pump running but consuming more energy than expected often has dirty coils, low refrigerant, or a failing component forcing the system to work harder. We restore efficiency with a thorough diagnostic and targeted repair.
A heat pump that only heats but won't cool (or vice versa) typically has a faulty reversing valve — the component that switches the system between modes. This is a common, repairable issue that our technicians handle regularly.
