Furnace Repair in Ontario

No heat in an Ontario winter is an emergency. Toronto Mechanical repairs gas furnaces, electric furnaces, boilers and heat pumps fast — with licensed, insured technicians and upfront pricing so you know the cost before we start.

Furnace Problems We Repair

  • Furnace not producing heat or blowing cold air
  • Pilot light won't stay lit or ignitor failure
  • Furnace short cycles or won't start at all
  • Loud rumbling, banging or squealing noises
  • Blower runs continuously or won't stop
  • Frequent breaker trips or error codes on the thermostat

Gas Furnace Safety

  • If you smell gas or suspect a carbon monoxide issue, leave the home and call your gas utility immediately. For all other furnace problems, our licensed technicians perform a full safety inspection with every repair — checking the heat exchanger, burners, venting and combustion to keep your family safe.

Repair or Replace Your Furnace

  • A well-maintained furnace lasts 15–20 years. If yours is older, needs repeated repairs, or your heating bills keep climbing, a new high-efficiency furnace can pay for itself in energy savings. We'll give you an honest recommendation and a free replacement quote — never pushing a new system you don't need.
