Furnace installation & replacement in Oshawa, ON
Oshawa-based, owner-operated, and here to help with proper sizing, high-efficiency units, and permits handled when required.
Furnace installation by someone who actually knows Oshawa
Oshawa's housing stock runs the full range — post-war bungalows in Lakeview and O'Neill, mid-century splits in Centennial, and newer builds in Windfields and Kedron. Each era of construction comes with its own furnace sizing and venting requirements. Zack has been installing furnaces across Oshawa for over 15 years and knows exactly what each neighbourhood needs — including whether a permit is required and handling it if so.
Proper sizing
An oversized furnace short-cycles and wears out fast. An undersized one never keeps up. We calculate your home's actual heat load before recommending a unit.
Permits handled
A permit is required in some cases depending on the scope of work. We assess whether one is needed and handle everything if it is — you don't have to think about it.
Single-day install
Most furnace replacements are completed in a single day. Old unit removed, new unit installed, tested, and commissioned before we leave.
Transparent pricing
You get a clear quote before anything starts. No surprise line items, no upselling to a unit bigger than your home needs.
What we install
Durham Region winters are serious. The right system depends on your home's size, age, and existing venting. Here's what we carry:
High-efficiency gas furnace (95–98% AFUE)
Required for all new gas furnace installations in Canada. Significantly lower operating costs — and we confirm your venting is compatible before quoting.
Furnace + heat pump hybrid
Pairs a gas furnace with a heat pump. The heat pump handles most heating; the furnace kicks in on the coldest days. Eligible for Ontario HRS rebates.
Propane furnace
For Oshawa properties not connected to natural gas. Same high-efficiency options, properly configured for propane supply and venting.
Replacement of oil or older systems
Converting from oil or an aging low-efficiency unit? We handle the full switchover including new venting, gas line connection, and disposal of the old system.
What does a new furnace cost in Oshawa?
Costs vary based on efficiency rating, home size, and whether new venting is required. Typical installed ranges for Oshawa homes:
High-efficiency gas furnace (95–98% AFUE): $4,000 – $8,000
Hybrid system (furnace + heat pump): $7,500 – $18,000 — heat pump portion eligible for Ontario HRS rebate up to $7,500
The most accurate number comes from a free in-home quote — we need to see your existing setup to price it properly.
What to expect from an installation
Here's how a typical furnace replacement goes from first call to warm home.
Free quote & assessment
We assess your home, existing equipment, and heating needs. We calculate the right unit size for your square footage — not just what fits in the space.
Honest recommendation
We'll tell you exactly what system makes sense for your home and budget. If your existing furnace has years of life left, we'll tell you that too.
Permit pulled, install scheduled
If a permit is required, we handle the application before the job starts. Most installations are booked within a few days of the quote.
Old unit removed, new unit installed
Clean, careful work. Most replacements are completed in a single day. The old unit is hauled away and disposed of responsibly.
Testing, commissioning & walkthrough
We run the system through a full heating cycle, verify all safety controls, check for gas issues, and walk you through the new unit before we leave.
What Oshawa customers say
"Our furnace quit on a Thursday in mid-December. Even though Zack was busy, he showed up Saturday morning and had a new furnace installed and running within a few hours. His quote beat the larger companies by a lot — we won't be calling anyone else."
A note from Zack
A furnace installation is one of the bigger purchases a homeowner makes, and I take that seriously. The worst thing I can do is put in a unit that's the wrong size, cut corners on the permitting process when it's required, or leave someone with a system they don't understand how to use. I've seen that happen with other contractors and it's not how I work.
Oshawa is home base for me. I've installed furnaces in the older bungalows around Lakeview, the mid-century homes in O'Neill, and the newer builds up in Windfields and Kedron. Every house is a bit different and every quote reflects that. If you're thinking about replacing your furnace — this winter or next — call me and we'll figure out what actually makes sense for your home.
