Central Oshawa and the O'Neill area hold pre-1960 housing with original venting, cast iron boilers in places, and furnaces well past their expected life.

Oshawa HVAC Questions Answered
How quickly can you get to Oshawa?
Two hours is our target across Downtown Oshawa, O'Neill, Taunton, Windfields, and Lakeview, with 24/7 dispatch for gas emergencies, red tags, and no-heat calls.
Do you service cast iron boilers in older Oshawa homes?
Yes. We repair and replace cast iron sectional boilers and hydronic systems, including circulator pumps, expansion tanks, and low-water cutoffs. Where replacement makes sense we can move you to a condensing boiler without redoing the radiators.
Do you clear Enbridge red tags in Oshawa?
Yes. Our TSSA G1/G2 technicians handle the inspection, repair, and signed clearance so Enbridge can restore gas service, typically within 24 hours of our first visit.
Is Oshawa inside your regular service area?
Yes. Oshawa is the eastern edge of our regular coverage and carries the same two-hour emergency target, 24/7 gas coverage, and 2-year labour warranty as the rest of the GTA.
