Ductwork design and installation, furnaces, ventilation, make-up air and garage heat — for builders, contractors and homeowners taking on a serious renovation.

Everything a heating system can do is decided before the drywall goes up. Undersized returns, a trunk line squeezed around a beam, a bedroom fed by a single branch at the end of the run — those become permanent comfort problems that no thermostat setting can fix.
We handle the mechanical side of new builds and renovations across the region: layout and sizing, sheet metal, venting, furnace and ventilation, and the final balance.

A furnace can only deliver what the ductwork lets it move. Air needs a path in and a path back — undersized returns are the most common fault we find in otherwise well-built homes, and they show up as noisy registers, a cold room above the garage, and a system that runs longer than it should.
On a new build we plan trunk and branch sizing around the actual room-by-room load, keep runs as short and straight as the framing allows, and put returns where the air actually needs to come back from. On two-storey homes, that usually means dedicated upstairs returns rather than hoping the stairwell does the work.
A basement development, an addition or a gutted bungalow all raise the same question first: can the existing system carry the new load? Sometimes the answer is yes with rebalancing and a couple of new runs. Sometimes the furnace is already at its limit and the honest answer is that it needs to be addressed as part of the project.
We'd rather tell you that at the quoting stage than have you discover it the first cold week after the drywall is painted.
Heating a detached garage or a shop is its own problem: the space is tall, poorly insulated by comparison, and opened to −25 °C every time the door goes up. We install Reznor and Lennox unit heaters sized for the volume and for how the space is used — a car parked and warmed is different from a shop you work in all day.
On acreages this is one of our most common jobs, often alongside a propane furnace in the house.
Trades that show up when they say they will are worth more than trades that are cheapest. We give realistic dates, coordinate with framing, plumbing and electrical, and we don't leave a rough-in half finished while we chase another job. If a schedule slips on our end, you hear it from us first.
Send us the plans and we'll put together a mechanical quote; for renovations we'd rather walk the space, because what's behind the walls decides the price.

Yes. We work with contractors on new builds and renovation projects and schedule around the trades ahead of us so the job keeps moving.
Yes — layout, sizing, trunk and branch runs, returns, venting and ventilation. Getting ductwork right is what separates a house that heats evenly from one that always has a cold bedroom.
A renovation usually means extending or rebalancing the existing system rather than replacing it. We assess whether the current furnace can carry the added load before anything is installed.
Yes — Reznor and Lennox unit heaters for garages, shops and outbuildings. Very common on acreages around Sturgeon County.
Yes, including the commercial side: restaurants, shops and multi-unit buildings.
We do, for the mechanical scope, in the communities we serve. JD holds municipal licensing in Edmonton and St. Albert.
