Your furnace shuts down, makes noise, or blows cold air in the middle of winter? We repair gas and electric alike, with the full certifications: RBQ 15.2 licence, CMMTQ member, and the TAG1 card for gas. Transparent diagnosis, price given before we touch anything, by our in-house team.
A furnace breakdown in deep cold is urgent and it is serious
When the furnace gives out in January, the house cools down fast - and in Quebec, that is not just a comfort question. A heating failure in deep cold can become a risk to the house (frozen pipes) and to the occupants. It is the kind of repair that should not wait, and that calls for someone qualified.
The most common furnace failures: an ignition problem, a fouled or faulty burner, a heat exchanger issue, a blower no longer pushing air, a thermostat or a filter. On a gas furnace, some of these problems touch on safety - carbon monoxide is not something to improvise with.
Gas and electric are not repaired quite the same way. A gas furnace burns a fuel: igniter, burner, gas valve, flame sensor and heat exchanger are the parts that cause trouble, and a cracked heat exchanger is the serious risk on the carbon monoxide side. An electric furnace heats through elements: there, it is the heating elements, the relays and the sequencers that give out. In both cases, the blower and the thermostat can also be at fault. We repair both, and gas always by certified people.
That is exactly why the certifications matter. Air 2 holds the RBQ 15.2 licence, is a CMMTQ member, and our technician holds the TAG1 card to work on all gas systems. We repair gas and electric alike, and we never subcontract a gas system to someone we do not control.
Furnace repair is part of Air 2's HVAC repair silo: a human answers, the price comes before the job, and the certified in-house team is on site.

The furnace failures we see most
Gas or electric, each one gets diagnosed before it gets priced - and some of them touch on safety.

"For a gas furnace, you need a real specialist"
You are right - and that is precisely why we keep our certifications current. Many general HVAC companies touch gas without having all the cards in order, or subcontract the gas portion to a third party. With us, it is our in-house certified team doing the work: RBQ 15.2 licence, CMMTQ member, TAG1 card for gas.
The other thing we hear: "my furnace is old, it is surely beyond repair, we just have to replace it." Not necessarily. Plenty of failures - ignition, burner, blower - repair very well on a furnace that still has years ahead of it. We diagnose, we give you the price before touching anything, and you decide.
That said, if your furnace really is at the end of its life, we do the honest math with you: in Quebec, replacing an old furnace with a central heat pump qualifies for the LogisVert rebate, which often changes the equation. We do not push you toward replacement, but we show you the scenario - and if you choose it, we handle the central heat pump installation.
