In short:
• High-efficiency furnaces convert 90% or more of fuel into usable heat, making them the standard for new installations in Canada.
• Regina’s harsh winters make proper installation and regular maintenance critical for performance and safety.
• Local programs, including SaskEnergy’s Heating Affordability Program, may reduce the cost of upgrading.
A high-efficiency furnace is the most practical heating upgrade a Regina homeowner can make. With temperatures regularly plunging well below freezing, a furnace that wastes fuel is a furnace that costs more every month it runs.
If you are researching a high efficiency furnace in Regina SK, understanding how these systems work, what installation involves, and how to keep them running well will help you make a confident decision. Certified Plumbing & Heating Ltd supplies and installs furnaces alongside air conditioners, boilers, water heaters, and plumbing systems across Regina and the surrounding area.
What Makes a Furnace “High Efficiency”
Energy efficiency in furnaces is measured by the Annual Fuel Utilization Efficiency (AFUE) rating, a seasonal measure of fuel efficiency. The higher the AFUE rating, the more efficient the unit. Natural gas furnaces sold in Canada must be high-efficiency with an AFUE rating of 90% or more.
A high-efficiency furnace adds a secondary heat exchanger that captures additional heat from exhaust gases before they exit the home, extracting energy that would otherwise be wasted. This design is why condensing furnaces can reach AFUE ratings close to 98%.
Here is a quick comparison of furnace efficiency tiers:
| Efficiency Tier | AFUE Range | Venting Type | Typical Use Case |
| Standard | 80% | Metal flue/chimney | Older homes, replacement only |
| High-Efficiency | 90-96% | PVC or ABS plastic pipe | Most new residential installs |
| Premium High-Efficiency | 97-98%+ | PVC or ABS plastic pipe | Cold climates, maximum savings |
Today’s high-efficiency furnaces can be vented via PVC or ABS plastic pipes directly through walls, while most conventional models must be vented through chimneys. This venting difference is one of the first things a technician will assess during an installation quote.
What the Installation Process Involves
Replacing or installing a high-efficiency furnace is not a simple swap. Several components of the existing system may need modification.
• Venting: High-efficiency furnaces require different venting than standard units. If your home previously had a mid-efficiency furnace, the old metal flue cannot be reused.
• Condensate drainage: Condensing furnaces produce water that must be properly drained. A condensate line must be routed to a floor drain or utility sink.
• Electrical: Modern high-efficiency furnaces have different electrical needs, and all electrical work must be done by licensed electricians in Regina.
• Ductwork: High-efficiency furnaces often expose existing ductwork problems that were masked by a less powerful unit.
According to Natural Resources Canada’s EnerGuide furnace guide, the AFUE rating does not account for the electricity used by blower motors and controls, so a complete cost-of-ownership calculation should factor in both gas and electrical consumption.
If you experience a no-heat emergency such as a furnace or boiler not operating, emergency service is available 24 hours a day. Knowing your contractor offers around-the-clock support is especially relevant during a Regina winter installation.
SaskEnergy Programs and Financial Incentives
Cost is a common barrier to upgrading, but local programs can help offset the investment.
SaskEnergy launched a furnace replacement program to help homeowners facing financial barriers lower their heating bills. The Heating Affordability Program (HAP) provides eligible income-qualified households with a new high-efficiency furnace free of charge.
Furnace replacements under HAP include the installation of a 96% AFUE single-stage natural gas furnace, required modifications to the home’s venting, three furnace filters, and, if required, a programmable thermostat.
With a new high-efficiency furnace, participating customers can expect to save up to $650 annually on natural gas and electricity costs, according to SaskEnergy.
Certified Plumbing & Heating Ltd is proud to offer a number of SaskEnergy Network Member programs and services, which means they can help eligible customers connect with available incentives during the installation process. Financing is also available for homeowners who do not qualify for grant programs.
Keeping Your High-Efficiency Furnace Running Well
Installation is only the beginning. A condensing furnace has more components than a standard unit, and each one needs periodic attention.
HVAC professionals strongly recommend annual maintenance for your furnace and related equipment. Doing so keeps your furnace running safely, cleanly, and properly, and helps identify any problems before they get worse.
Key maintenance tasks include:
• Replacing the air filter every 1-3 months, depending on household conditions
• Monitoring the secondary heat exchanger and condensation drains to prevent clogs or shutdowns
• Scheduling an annual inspection before the heating season begins
• Testing the thermostat and verifying ignition sequences are functioning correctly
Certified Plumbing & Heating also services all makes and brands of furnaces, air conditioners, boilers, and water heaters, so ongoing maintenance does not have to mean finding a separate contractor after installation.
Frequently Asked Questions
What AFUE rating should I look for in a new furnace in Regina? Natural gas furnaces sold in Canada must have an AFUE rating of 90% or more, with the most efficient units reaching 98-99%. For Regina’s climate, aiming for 95% or higher is a practical target.
Does a high-efficiency furnace require a new chimney? No. High-efficiency furnaces vent through PVC or ABS plastic pipes directly through walls, so a traditional chimney is not needed. The old flue may be capped or repurposed.
How long does a high-efficiency furnace last with proper maintenance? With proper maintenance, a quality furnace can often deliver 15 to 20 years of dependable service.
Can I get help paying for a new furnace in Regina? Through the Heating Affordability Program, eligible income-qualified households can receive a new high-efficiency furnace free of charge to replace their low-efficiency furnace. Ask your contractor whether you qualify before committing to a purchase.
Upgrading to a high-efficiency furnace in Regina is a practical long-term investment, particularly given the province’s heating demands. Understanding AFUE ratings, installation requirements, venting changes, and maintenance needs puts you in a much stronger position when getting quotes and comparing options.
