HVAC Service That Knows Oshawa, House by House
From century homes near downtown Richmond Street to postwar bungalows around the old GM lands and the newer subdivisions climbing into north Oshawa, every house here heats and cools a little differently. We size, install, and service HVAC around the home in front of us, and the lake-effect weather that comes with living on the north shore of Lake Ontario.
Built in Oshawa, Trusted Across Durham Region
We started Oshawa Heating & Cooling because homeowners in Durham's regional capital were tired of contractors who treated the city like just another stop on a Greater Toronto Area route.
Oshawa sits on the north shore of Lake Ontario as the largest city in Durham Region, and that position shapes how every home here performs. Lake-effect snow and bitter onshore winds push furnaces hard through long January stretches, while humid air drifting off the lake forces air conditioners and heat pumps to work overtime in July and August. The housing stock ranges from century homes near the Oshawa Creek corridor and downtown to postwar worker bungalows built for the GM families, with newer two-storeys and townhomes filling in the north end. Each one has its own quirks, and we size every installation to match.
Our shop on Richmond Street West puts us a short walk from Oshawa's downtown core and minutes from Memorial Park, with Whitby, Ajax, and Pickering to the west and Bowmanville, Newcastle, Courtice, and Port Hope stretching east along the lakeshore. When a furnace goes down on a sub-zero February night, you aren't waiting on a crew dispatched from across the GTA, you're getting a local technician who knows the neighbourhood, the housing stock, and the fastest route to your door.
That local focus shows up in the work we do every day: high-efficiency furnace installation and repair, central and ductless air conditioning, heat pumps that shoulder the swing seasons, fireplace installations, thorough duct cleaning, and smart thermostat upgrades that actually move the needle on your monthly energy bill. Whether it's a quick thermostat swap in a downtown condo or a full ductless install in a 1950s bungalow with no existing ductwork, the standard never changes.
Why Homeowners Across Oshawa and Durham Trust Us
Fast, honest service across Durham Region, with quotes laid out clearly before a single tool comes out of the truck. From an emergency furnace repair in Whitby or a new ductless system in a Bowmanville bungalow to a heat pump tune-up near Oshawa's downtown, our technicians show up on time and do the work properly the first time.
What You Can Expect From Every Visit
We diagnose before we recommend, every time. Whether it's a furnace short-cycling in a century home near downtown, an air conditioner losing ground to August humidity in a north-end two-storey, or a heat pump that won't switch modes come spring, we walk you through what's actually wrong, what the fix costs, and which options make sense for your home before any work starts. No vague answers, no surprise add-ons, no pushing equipment you don't need.
We install and service the systems Oshawa and Durham Region homeowners actually rely on, from high-efficiency gas furnaces to ductless mini-splits for older houses that were never built with ductwork. Our team also handles thorough duct cleaning, smart and programmable thermostat replacement, and code-compliant fireplace installation, so your whole-home comfort lives under one roof instead of scattered across three different contractors.
