Furnace Replacement In Nepean
Many Nepean homes are on their second or third furnace, and some were converted from oil to gas decades ago. Over that time, most have also had new windows, added insulation or a finished basement, which changes how much heat the house actually needs.
That's why we don't just swap in the same size as your old unit. We look at your home as it is today, check that the existing ductwork can handle the new furnace, and recommend a system that fits.

Finishing a basement adds living space that needs heat. We take that into account so every floor stays comfortable.
Understanding Your Furnace Options
Not all high-efficiency furnaces heat your home the same way. While most new furnaces meet similar efficiency standards, the biggest differences are in how they operate, how evenly they heat your home, how quiet they are, and how much they cost.

So Which One Do You Actually Need?
More expensive doesn’t automatically mean better for your home. The right choice depends on your home’s size and layout, existing ductwork, comfort expectations, budget, and how long you plan to stay in the home. Colair can walk you through the differences and help you decide which features are actually worth paying for.
Not Sure Which Brand To Choose? Colair Can Help You Find The Right Fit
Our Ottawa furnace installers work with every major furnace and air conditioner brand, each offering different warranties, efficiency ratings, features and price points. We’ll help you compare your options and choose the system that best fits your home, comfort needs and budget.
Choosing The Right Furnace Depends On A Few Key Factors
When it comes to gas furnace replacement, a new furnace should be matched to your home, not just to the size of the one you’re replacing. Before we recommend anything, our Ottawa furnace installers look at how your home actually heats.
Home Size & Layout
Square footage, number of floors, and how your rooms are laid out all affect how much heat your home needs and where it needs to go.
Heat Loss & Insulation
Insulation, windows, and air leaks change how quickly your home loses heat during an Ottawa winter, and that changes the size of furnace you need.
Ductwork & Airflow
Your ducts have to move the air your new furnace produces. We check that they can handle it, so every room gets heat without noisy vents.
Venting & Gas Supply
High-efficiency furnaces vent differently than older models. We confirm your venting and gas line are ready for the new unit.
Your Comfort Goals
Quieter operation, more even temperatures, fewer cold rooms. We factor in what matters most to you.
Your Budget
We show you options at different price points and explain what you get with each, so you can choose with confidence.
Proper Furnace Sizing Makes a Bigger Difference Than You Think
An oversized furnace turns on and off too often and wears out faster, while an undersized one runs constantly and struggles on the coldest days. Colair can help you select the perfect fit for your house.

Furnace rebates and energy-efficiency incentive programs change often, and eligibility depends on your home and the equipment. Ask us about currently available incentives when you request your quote.
The Process
Most furnace replacements are completed in a single day. We'll confirm the timeline for your home when we quote the job.
We size your furnace based on your home, not the size of your old unit. See finding the right furnace above.
If your air conditioner is also getting older, replacing both together can make sense since they share the same blower and ductwork. We’ll tell you honestly whether it’s worth it. Learn more about our AC installation.
Timing & Service Area
If your furnace is 15+ years old or needs frequent, costly repairs, replacement is usually the better long-term value. We’ll give you an honest recommendation either way. See the signs it’s time above.
Before it fails. Replacing your furnace in the spring, summer, or early fall gives you time to choose the right system instead of rushing an emergency install in the middle of winter.
