Heat Pump Repair Built for an Ontario Winter

When the temperature drops, your heat pump starts doing things you have never seen before, and it is hard to know whether to worry. Steam rolls off the outdoor unit and cool air comes through the vents.

We work the refrigerant side of the machine as well as the controls, so we test the charge, the reversing valve, the defrost board and the changeover to your backup heat. We are also the heat pump installers who put these systems in, so we know how yours should behave in February.

You get a heat pump repair that starts with a real diagnosis, so you know whether the unit is faulty or doing its winter job.

Normal in the Cold, or Something to Call About?

In a cold snap, plenty of what looks wrong is your heat pump working properly. A heat pump repair visit starts by telling that apart from a real fault.

What you are seeing What it means
Steam pours off your outdoor unit in the cold. That one is normal.
It pauses, then blows cool air through your vents. That is the defrost cycle.
Frost forms on the unit and clears within ten minutes. That is normal too.
Your furnace runs alongside it in deep cold. They share the work by design, though a weak furnace needs furnace repair.
A sheet of ice sits there and never clears. Give us a call.
The air from your vents stays cool all the time. Call us, because a refrigerant leak often sits behind that.
The unit hums but nothing turns outside. An outdoor fan that will not spin is electrical, so call us.
It trips the breaker or keeps starting and stopping. Stop resetting it and call us.

What a Heat Pump Repair Visit Includes

A real diagnosis first

Every heat pump repair starts with your technician testing the refrigerant charge, the reversing valve, the defrost board and the capacitor, so you find out which part failed.

Both modes tested before we leave

One machine heats your house and cools it, so we run both modes before the van moves and you go into summer knowing the cooling side works too.

The price before the work

We diagnose first and price the repair second. Our pricing is fair and upfront: you get the price in writing before any work begins, and the decision stays yours.

We repair ducted and ductless systems, and the diagnosis works the same on both.

Why Choose Our Team

Sina, our owner and main technician, has worked in this region for over 10 years, and heat pumps have been part of it throughout. Being an Authorized Lennox Dealer gives us factory training and parts access when a control board has to be replaced.

We are a five-time HomeStars Best of Award winner. Most heat pump repair ends on the sealed refrigerant side of the machine, and that is the part of the job we know best.

Sina is lovely, hard working, honest. He worked very hard to make sure we got the right solution for our heat pump.

Book a Heat Pump Repair Visit

Tell us what the unit is doing and when it started. We come out, find the fault, and give you a straight answer.

Repair it, or replace it?

Age is the first thing we look at. A unit in its twelfth season with a failed compressor rarely earns the parts, and a second major fault in one winter says much the same. If replacing makes better sense, we tell you, and our cold-climate heat pump install page covers what that involves.

We will work on the system you already own

We specialize in Lennox, and we service other major heat pump brands as well, including units another company put in. Call us and we will confirm yours. Most of our heat pump repair service goes to equipment we did not install.
