What do people ask about furnaces?
Answers from Jackman Mechanical, October 2026. In Ontario, the TSSA says furnace maintenance must be done by TSSA-registered contractors with TSSA-certified gas technicians (TSSA).
Why is my furnace not turning on?
The disconnect switch may be turned off, or the control board may be faulty. The disconnect switch usually looks like a light switch on or near the furnace, so check that one first. If it is on and the furnace still will not start, call, or send a request with a photo of the label inside the furnace door.
Why is my furnace blowing cold air?
It may be a problem with the gas valve or the flame rod, the sensor that tells the furnace its burner has lit. Both are work for a certified gas technician.
How much does furnace repair cost in Toronto?
Typically $450 to $1,500, depending on the repair.
How much does a new furnace cost in Toronto?
Typically $4,000 to $7,000 all in. It depends on the size of the furnace your home needs.
Who offers emergency furnace repair near me?
Jackman Mechanical Ltd. does emergency furnace repair in Toronto, North York, Mississauga, Markham and Ajax. Emergency repairs are 24/7 by phone at (416) 888-1371.
Why does my furnace keep turning on and off?
That is called short cycling. The furnace detects a failure, shuts itself off, and tries to start another cycle. A technician finds the failure it keeps detecting.
How often should I have my furnace serviced?
Once a year. The Government of Ontario also asks owners to have fuel-burning appliances, chimneys and vents cleaned and inspected by professionals every year (Government of Ontario).
Should I repair or replace my furnace?
It depends on what is wrong with it. Have a technician diagnose the problem before you make that decision.
Is a heat pump better than a gas furnace for a Toronto home?
No, in Jackman Mechanical's view. A heat pump still needs a backup heat source for a Toronto winter, so it does not replace the furnace on its own.
What do people ask about natural gas lines?
For a new appliance, a photo of your gas meter and of the spot where the appliance will go shows most of what a gas technician needs to see.
How much does gas line installation cost in Toronto?
It depends on how much piping is installed, the size of the pipe and what needs to be done, so a gas technician has to see it to price it. Send a request with a photo of your gas meter and the spot where the appliance will go, or call.
How much does it cost to install a natural gas line for a BBQ?
Typically $1,000 to $5,000, depending on the size of the gas line and how far it runs.
Who can install or connect a gas stove in Toronto?
A TSSA-certified gas technician holding a G2 or G1 certificate. The TSSA says gas appliance work in Ontario must be done by TSSA-registered contractors, who must hire TSSA-certified gas technicians (TSSA).
Can I convert my propane BBQ to natural gas?
Yes, you can, with the natural gas conversion its maker approves for that model. The conversion and the new natural gas line to the BBQ are gas work for a certified gas technician.
What should I do if I smell natural gas in my house?
Get everyone out of the house right away. Enbridge Gas says to leave doors and windows open behind you if you can do it without delay, and not to use phones, switches, lights or anything electronic on the way out. Once you are safely away, call its 24-hour emergency line at 1-866-763-5427 or 911 (Enbridge Gas). When the gas has been made safe, a gas technician such as Jackman Mechanical finds and fixes the leak.
Do I need a permit or inspection for a new gas line in Toronto?
Not a City permit for the gas line itself, in Jackman Mechanical's experience. What matters is who does it: a TSSA-certified gas technician, G2 or G1, working for a TSSA-registered contractor (TSSA). Replacing a furnace is different: Toronto Building lists it as a stand-alone HVAC permit, in the permits guide.
Can my existing gas line handle another appliance?
It depends on how many BTUs (British thermal units) the appliance you are adding uses, compared with what the gas line to your house supplies. A gas technician checks that before it is hooked up.
How much does it cost to move or cap a gas line?
Typically $400 to $1,000, depending on where it is being moved and the size of the gas line.
Can I run natural gas to an outdoor fire pit or pool heater?
Yes, as long as your gas supply has enough to run those appliances as well.
Why is my natural gas bill so high?
In the heating season you use more gas than in summer. A high bill can also mean appliances that are not very efficient.
