What to know before hiring a HVAC technician in St. John's
Anything that touches gas in Newfoundland and Labrador, 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 Service NL, Engineering and Inspection Services. 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.
St. John’s is wet, windy and salty, with downtown row houses that date to the 1800s and hillside lots that channel water toward foundations. Heat pumps and electric heat are more common than gas, so an HVAC call here usually means a ductless or electric system, and parts often ship from the mainland.
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
- Are your technicians gas-certified, and can I see the ticket?
- Is the diagnostic fee credited toward the repair?
- Will you show me the failed part and explain the diagnosis?
- Is a replacement quote independent of the repair quote?
- Do you handle the permit and any rebate paperwork?
Frequently asked questions
Do I need a permit to replace a furnace in St. John's?
In Newfoundland and Labrador a gas furnace replacement needs a gas permit through Service NL, Engineering and Inspection Services 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 St. John's 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.
