Heat pumps run year-round, which means they wear year-round. Blowing warm air in July, icing up in January, or short-cycling and spiking your hydro bill — we diagnose and repair all major heat pump brands across Guelph, usually same-day.

Low charge means weak heating and cooling and rising bills. We find the leak, repair it, and recharge to spec — not just top up and hope.
A solid block of ice in winter means the defrost cycle has failed. Running it that way risks the compressor — we fix the cause, not the symptom.
Stuck in heating or stuck in cooling. A classic heat-pump-only failure that many general HVAC techs misdiagnose — we repair or replace the valve.
Failed sensors and control boards that leave the unit icing up or short-cycling in cold weather.
The most common wear items on any system that runs year-round. Usually a same-day fix.
Wrong staging, backup heat running when it shouldn't, wild temperature swings — often a configuration fix rather than a parts bill.
Most heat pump repairs land between $250 and $900. Here's how we help you decide when the number comes back bigger:
If your heat pump is under 10 years old, a repair is almost always the right call. If it's over 12 years old, or the compressor or reversing valve has failed, we'll price the repair and a replacement with current rebates side by side — and tell you which one we'd choose for our own house. Newer cold-climate units heat further into winter on less electricity, so a big repair bill on an old unit is sometimes money better spent on a new heat pump installation.
Mitsubishi, Daikin, Lennox, Carrier, Goodman, LG, York and more — including cold-climate models that carry most of a Guelph winter.
We repair ducted central heat pumps, ductless mini-split heads, and hybrid setups paired with a gas furnace. Diagnosis is quoted up front and applied to the repair, and you approve the price before any work starts. We service Guelph, Fergus, Elora, Rockwood, Erin, Acton, Puslinch and the rest of Wellington County.
What Guelph homeowners ask us when their heat pump acts up.
Short bursts of cool air during the defrost cycle are normal. Continuously cold air usually points to a refrigerant leak, a stuck reversing valve, or a failed defrost control — all repairable. If backup heat is carrying the whole load, your bills will show it before your thermostat does.
Light frost is normal in winter; a solid block of ice is not. Common causes are a failed defrost cycle, low refrigerant, a faulty outdoor fan motor, or blocked airflow. Turn the system to emergency heat and call — running it iced up can damage the compressor.
Most repairs land between $250 and $900 — capacitors, contactors, defrost boards, fan motors and refrigerant leaks make up the bulk of calls. Compressor or reversing valve failures run higher, which is when we'll price a repair and a replacement with current rebates side by side.
Annually at minimum — a heat pump runs year-round, so it works roughly twice the hours of an air conditioner. Twice-yearly checks (spring and fall) are worthwhile for older units or homes where the heat pump is the primary heat source.
