The KeepRite N9MSE price reflects its position as a practical high-efficiency furnace rather than a flashy premium comfort system — and honestly, that is part of its appeal.
It delivers reliable 95% efficiency, straightforward operation, and lower upfront costs compared to higher-end variable-speed or modulating systems. For many Canadian homeowners replacing an aging 80% furnace, that is more than enough.
⚠️ Important: The N9MSE has been discontinued by KeepRite. Some Ontario contractors and distributors may still have remaining inventory available, but availability is becoming limited in 2026.

The N9MSE was never designed to compete with premium modulating furnaces — and honestly, that is part of its appeal.
It offers:
- 95% AFUE efficiency
- Straightforward operation
- Lower upfront costs
- Proven heating reliability
For many homeowners replacing an older 80% furnace, this model still provides a noticeable improvement in comfort and winter gas savings without the higher price tag of variable-speed or communicating systems.
The KeepRite Performance Series N9MSE is a reliable high-efficiency gas furnace designed for homeowners who want dependable heating performance, and the competitive KeepRite N9MSE price makes it appealing for budget-conscious buyers.
Although discontinued, the N9MSE still remains attractive because of its:
The biggest question is not performance — it is whether you can still find new warranty-eligible stock locally.
This furnace makes the most sense for homeowners who care more about dependable heating and practical operating costs than premium smart-home features.
Most homeowners in Ontario and across Canada typically pay between $2,800 and $4,000 installed for the KeepRite N9MSE.
Several things affect the final price:
Larger BTU models naturally cost more than smaller configurations.
Older homes sometimes require venting updates, drainage modifications, or gas line adjustments that increase labour costs.
Those extra labour requirements can easily add several hundred dollars to the installation cost.
Because the N9MSE is discontinued, pricing can vary depending on local stock availability.
Some contractors discount remaining inventory, while others charge more because the model is becoming harder to source.
Installation pricing in Hamilton, Burlington, Oakville, or Kitchener may vary depending on labour demand and permit costs.
Comparing at least three quotes is still the safest way to avoid overpaying.
A standard KeepRite N9MSE installation quote should typically include:
Labour alone typically ranges between $800 and $1,400 depending on the project.
On paper, the N9MSE looks fairly basic. In real homes, though, it performs better than many homeowners expect.
The heating output is strong and consistent, especially in smaller and mid-sized homes. Since this is a single-stage furnace, it runs at full heating capacity whenever heat is needed, you will notice heating cycles slightly more compared to a two-stage system.
That said, many homeowners upgrading from older 80% furnaces still notice a meaningful improvement in overall comfort and efficiency.
Noise levels are reasonable as well.
The N9MSE is not the quietest furnace KeepRite has ever made, but it is noticeably quieter than many older builder-grade systems thanks to:
However, it is still louder than premium variable-speed systems.
Most homeowners upgrading from aging furnaces usually notice:
Another advantage of the N9MSE is its simpler overall design. Because it does not rely heavily on advanced communicating electronics or complex modulating systems, servicing and long-term maintenance are often more straightforward compared to premium furnace models.
At 95% AFUE, the furnace also wastes very little fuel compared to older mid-efficiency systems, which can help reduce monthly heating costs during long Canadian winters.
The biggest concern with the N9MSE is not performance — it is long-term availability.
Because the furnace has been discontinued:
- Certain replacement parts may eventually become harder to source
- Future compatibility with newer thermostat platforms may become limited
- Remaining inventory availability continues shrinking
Comfort is also more basic compared to premium furnaces. Since the system operates at full heating output whenever it runs, temperature swings are slightly more noticeable than with two-stage or modulating systems.
Good Efficiency Without Premium Pricing
At 95% AFUE, the furnace wastes very little fuel compared to older mid-efficiency systems.
Simpler Systems Can Be Easier to Maintain
Many HVAC contractors still like furnaces like this because fewer advanced electronics often mean simpler long-term servicing and repair costs.
Proven Heat Exchanger Design
KeepRite’s RPJ stainless steel heat exchanger has a solid reputation for durability and long-term performance.
Instead of focusing on marketing terminology, here is what these features actually mean for homeowners.
The Rigid Press Joint stainless steel heat exchanger is designed to:
KeepRite’s RPJ stainless steel heat exchanger has been around for years and generally has a solid reputation for durability and heat transfer performance.
This system:
Unlike older pilot light systems, direct spark ignition:
The N9MSE can integrate with compatible heat pumps and thermostats, allowing hybrid heating setups that reduce winter operating costs.
Replacement parts may become harder to source 10–15 years from now compared to current-production furnaces.
KeepRite requires registration within 90 days to maintain the full 10-year parts warranty.
Missing that window reduces coverage to only 5 years.
Single-stage furnaces operate at full output whenever heating is required, which can create:
The N9MSE operates at approximately 95% AFUE.
Compared to an older 80% furnace, many Canadian homeowners save roughly:
For Ontario homeowners facing long winter seasons, those savings can become significant over time.
Historically, high-efficiency KeepRite furnaces qualified for:
