Furnace Down? Same-Day Repairs Across Ontario
Oshawa Heating & Cooling: Winters here don't forgive a failing furnace. We service aging single-stage units in older Oshawa neighbourhoods and the modulating condensing models in new builds, repairing no-heat calls fast and installing high-efficiency replacements when the math favours them.
Why Homeowners Call Us
Furnace blowing cold air on the coldest Oshawa night?
A furnace that quits overnight is a January emergency. Technicians head out across Ontario with stocked trucks and repair most faults on the spot.
Rapid Triage for Total No-Heat Calls
A dead furnace jumps the queue. Tell us the symptoms on the phone and we start narrowing the cause before the truck rolls, then confirm it with a full diagnostic on arrival. No heat means top priority, always.
Annual Tune-Ups That Catch Faults Early
A one-hour visit each fall catches the cracked igniter, the drifting gas pressure, and the worn blower bearing while they are still simple fixes. Homes we tune annually rarely call us for no-heat emergencies.
Every Furnace Make and Model Repaired
Single-stage, two-stage, modulating, gas or propane: if it heats a home, our techs have trained on it and carry the documentation. No furnace is too old, too odd, or too new for the trucks we run.
FAQ
Furnace Repair in Oshawa: Common Questions
How much does furnace repair cost?
Repairs start with a free quote after diagnosis. Ignition and electrical fixes sit at the lower end, motor and control board work higher. You approve the number before we start.
How quickly can you repair my furnace?
Honestly, it hinges on the failure. Sensor and ignition repairs take minutes once diagnosed, while special-order parts add a wait. We say so plainly and keep you posted either way.
Should I repair my furnace or replace it?
A cracked heat exchanger usually ends the repair conversation, since that fix rarely makes sense on an older unit. Nearly every other fault is worth repairing first.

What Oshawa Homeowners Say
Real feedback from neighbours we've helped stay comfortable year-round.
“Our gas fireplace pilot kept dying every cold night, and the tech traced it to a worn thermocouple, replaced it same visit, and relit everything perfectly.”

“We finished a basement bedroom addition and needed heat without ductwork. They recommended a single-zone mini-split, explained sizing clearly, and had it running within the week.”
