Heating
Fireplaces installed like the centrepiece they are.
A fireplace is the heart of a room — when it’s done right. Delson Air installs, replaces, and services gas and linear fireplaces across the GTA, from clean wall-mounted units in modern homes to stone-hearth feature walls in classic ones.
What we do
Fireplaces services, end to end.
Every install is performed by a TSSA-licensed gas technician, vented to code, and finished cleanly — so the result looks as good as it works. Browse our recent installs on the gallery page.
Linear gas fireplaces
Sleek wide linear units that disappear into modern marble, stone, or wood feature walls.
Traditional & stone-hearth
Built-in gas fireplaces with stone, brick, or classic mantle surrounds — warm and timeless.
TV-over-fireplace builds
Coordinated install and venting so a wall-mounted TV sits perfectly above the firebox.
Replacement & relines
Swapping out aging or unsafe gas inserts; bringing venting and gas lines up to current code.
Service & repair
Pilot, ignition, fan, and venting service so an older fireplace lights and runs the way it should.
