Frequently Asked Questions
What if the heating fails in deep cold?▾
Call a heating contractor right away, keep the house closed to hold heat, and run a trickle of water if you fear frozen pipes. If the house must be left, shut off the water and drain the low points.
Which heat pump for our winters?▾
One that holds efficiency at low temperatures. Ask the contractor for values at local temperatures and at what point backup heat takes over.
When should annual service happen?▾
September or October, before everyone calls at once. A fault found then is fixed without urgency and without premium pricing.
How do I protect the house when away in winter?▾
Keep a minimum temperature, have someone check on it, and consider a freeze alarm linked to your phone. An unheated house in January can lose its plumbing in one night.
How do I verify a heating contractor is licensed?▾
Ask for the RBQ licence number and search the Régie du bâtiment du Québec public registry.
HVAC in Saguenay: what to know
In Saguenay, heating is not a comfort, it is a necessity. Winters here rank among the coldest in Quebec, and a heating failure at minus 30 quickly becomes a safety problem for the house and the people in it.
Service before the season
Having the system checked in September or October is the basic rule here. A failing thermostat, a dead baseboard or a furnace that starts poorly all get fixed without urgency at that point.
Heat pumps in deep cold
A well-chosen heat pump runs much of the year but hands off to backup heat below a certain temperature. In this region, that crossover point is a major selection criterion, not a technical footnote.
Frozen pipes
When heat fails, pipes freeze fast. If you leave in winter, keep a minimum temperature and arrange for monitoring.
Licence
The contractor must hold a Régie du bâtiment du Québec licence, and belong to the CMMTQ for piping work.
