What to know before hiring a HVAC technician in Vaughan

Anything that touches gas in Ontario, including a furnace, boiler, gas fireplace or gas water heater, must be worked on by a certified gas technician and often needs a permit through Technical Standards and Safety Authority (TSSA). Ask for the technician’s gas ticket and the permit number for any installation or major repair.

If you smell gas, leave the building before you make any call, then phone your gas utility’s emergency line or 911 from outside. Do not use switches, phones or appliances inside. For a furnace that has simply stopped, check the thermostat batteries, the furnace switch, the breaker and the filter before booking a service call; those four checks resolve a surprising share of no-heat calls.

Vaughan is a city of large post-1990 subdivisions in Woodbridge, Maple, Thornhill and Kleinburg, with big lots, big houses and the roofs, furnaces and panels that were all installed within a few years of each other now coming due together. Finished basements and in-law suites are common, EV chargers and heat pumps are stressing 100-amp services, and the Vaughan Metropolitan Centre is adding condo towers. Alectra supplies electricity, Enbridge the gas, York Region the water.

Have this ready when you call

  • Furnace or heat pump make, model and approximate age
  • What the unit does when you call for heat or cooling
  • Any error code on the furnace board or thermostat
  • Filter condition and when it was last changed
  • Rebate paperwork if you are considering replacement

Questions to ask before booking

  1. Are your technicians gas-certified, and can I see the ticket?
  2. Is the diagnostic fee credited toward the repair?
  3. Will you show me the failed part and explain the diagnosis?
  4. Is a replacement quote independent of the repair quote?
  5. Do you handle the permit and any rebate paperwork?

Frequently asked questions

Do I need a permit to replace a furnace in Vaughan?

In Ontario a gas furnace replacement needs a gas permit through Technical Standards and Safety Authority (TSSA) and is inspected; a heat pump or air conditioner usually needs an electrical permit as well. Reputable installers include the permits in the quote.

Should I repair or replace an old furnace?

Get the diagnosis first. A failed igniter or blower motor on a 12-year-old furnace is usually worth repairing; a cracked heat exchanger on the same furnace usually is not. Ask for both numbers in writing and compare the replacement cost with rebates included.

Why is my heat pump running constantly in a Vaughan winter?

Cold-climate heat pumps are designed to run long cycles at low speed, which is normal. Constant running with the house still cold, ice building on the outdoor unit, or backup heat coming on early are the signs that need a technician.

What is a fair HVAC diagnostic fee?

Fees vary by company and by time of day; what matters is whether it is disclosed before the visit and whether it is credited if you approve the repair. Get that in writing when you book.
