Whatever Broke, the Same Crew Fixes It
Searching separately for a furnace company, an AC company and someone for the water heater wastes a cold evening. Megacity repairs the whole mechanical room: gas furnaces, central air, ducted and ductless heat pumps, and tank or tankless water heaters, anywhere in Toronto and the GTA.
Every truck leaves our East York shop stocked with the parts that actually fail — ignitors, flame sensors, capacitors, contactors, fan motors, thermostats — so a single visit closes out most calls. Gas-side work is done by TSSA-certified technicians, and every repair price is approved by you in writing before a panel comes off.
Cooling issue instead? Our AC repair Toronto page covers the common failures and what they cost.

Our Process
How a Toronto HVAC Repair Call Goes
1
Tell Us the Symptoms
Describe what the system is doing on the phone so the tech arrives with the likely parts on the truck.
2
On-Site Diagnosis
The technician tests the system end to end and shows you the failed component, not just a verdict.
3
Written Price
You get the repair cost in writing and approve it before any work starts.
4
Repair and Prove It
We complete the fix, run the system through a full cycle, and walk you through what was done.
Diagnostics
HVAC Repairs We Handle Every Week
Heating, cooling and hot water faults — most closed out on the first visit with truck-stock parts.
Furnace Not Heating
Ignitors, flame sensors, pressure switches and blower motors are the usual culprits on Toronto furnaces — most are truck-stock parts.
$150 – $500
AC Not Cooling
Capacitors, contactors, refrigerant leaks and frozen coils account for most summer calls. We test rather than guess.
$150 – $600
Heat Pump Stuck in One Mode
Reversing valve faults, sensor errors and defrost-cycle issues on ducted and ductless heat pumps, including cold-climate units.
Quoted after diagnosis
No Hot Water
Tank and tankless water heater faults — pilot and ignition failures, error codes, scale buildup, leaking valves.
Quoted after diagnosis
Short Cycling or Odd Noises
Systems that start and stop, bang, squeal or rattle are telling you a component is on its way out. Catching it early is cheaper.
$100 – $400
Thermostat and Control Faults
Mis-wired or failing thermostats and control boards that mimic bigger equipment failures. A frequent quick fix.
$100 – $350

Common Questions
HVAC Repair Toronto — FAQ
How much does HVAC repair cost in Toronto?
A service visit starts at $150, which covers getting a TSSA-certified technician to your door and diagnosing the fault. From there, most furnace repairs in Toronto run $150 to $500 and most AC repairs run $150 to $600 depending on the part. You get the exact price in writing and approve it before any repair work starts.
Do you repair all HVAC systems, or only the brands you sell?
We repair every major residential brand of furnace, air conditioner, heat pump and water heater. For new equipment we are an Authorized Lennox Dealer and also install Goodman, Ducane, Daikin, Kepler, Mitsubishi and Gree, but repair calls are never limited to those brands.
Can you come the same day?
Same-day HVAC repair is often available across Toronto and the GTA, because our trucks are stocked with the common failure parts — ignitors, flame sensors, capacitors, contactors and fan motors. Call (416) 286-5665 and we will give you the earliest real appointment rather than a promise we cannot keep.
Do you offer 24/7 emergency HVAC repair in Toronto?
Yes. The phone is answered 24/7 and we attend emergencies outside our regular 7 AM to 11 PM hours. Overnight calls carry a modest premium, quoted before the technician starts, so you always know the cost ahead of time.
When is repair no longer worth it?
If a furnace is over 15 years old or an AC is over 10 to 12 years old and the repair quote approaches half the cost of a new unit, replacement usually makes more sense. We price it both ways on the spot: the repair, and a replacement with lease-to-own financing available through Enbridge Sustain.
