When to Replace Your Furnace
A furnace typically lasts 15 to 20 years with proper maintenance. However, age alone is not the only factor. Here are the most common signs that it is time to invest in a new furnace rather than continuing to repair your existing one:
Your furnace is 15 years old or older and efficiency has noticeably declined
A cracked heat exchanger has been diagnosed, which poses a carbon monoxide risk
Your system still uses R-22 refrigerant (phased out in Canada) or outdated components
Heating bills keep rising despite regular maintenance and repairs
You have needed two or more major repairs in the past two years
Rooms heat unevenly or the furnace struggles to maintain the set temperature
The furnace makes loud banging, rattling, or grinding noises during operation
Visible rust, corrosion, or cracks on the furnace body or flue pipes
If your furnace shows any of these signs, a new installation is typically more cost-effective than ongoing furnace repairs. A modern high-efficiency unit can reduce your monthly gas bills by 20-40% while providing more reliable and even heating throughout your home.
Types of Furnaces We Install
Choosing the right furnace type depends on your home size, budget, and comfort preferences. We install all three major categories.
Single-Stage Furnace
Operates at one fixed output level, either fully on or off. These are the most affordable option upfront and work well for smaller homes or those on a tight budget. Typical AFUE ratings range from 80% to 92%.
Two-Stage Furnace
Runs at a lower output most of the time and ramps up to full capacity only when needed. This results in more consistent temperatures, quieter operation, and lower gas bills compared to single-stage models. AFUE ratings typically range from 92% to 96%.
Modulating Furnace
Continuously adjusts its flame and blower speed in small increments to maintain the exact temperature you set. This is the most efficient and comfortable option available, with AFUE ratings of 96% to 98%. Ideal for larger homes or homeowners who want the lowest possible energy bills.
Furnace Efficiency Ratings Explained
Furnace efficiency is measured by its Annual Fuel Utilization Efficiency (AFUE) rating, which tells you what percentage of gas is converted into usable heat. A higher AFUE means lower gas bills.
Standard Efficiency (80% AFUE)
- 20 cents of every dollar in gas is wasted
- Lower upfront cost but higher monthly bills
- Uses a chimney flue for exhaust venting
- Does not qualify for most government rebates
High Efficiency (96%+ AFUE)
- Only 4 cents or less of every dollar is wasted
- Saves $300-$600+ per year on gas bills
- Direct-vent (PVC pipe) exhaust, no chimney needed
- Qualifies for government and manufacturer rebates
We recommend 96% AFUE or higher for most Toronto homeowners. The energy savings typically pay for the difference in upfront cost within 3 to 5 years, and you may qualify for significant rebates that further reduce the investment.
Furnace Brands We Install
We are authorized dealers and installers for the most trusted furnace brands in North America. Every unit we install comes with a full manufacturer warranty, and we handle all warranty registration on your behalf.

Our Furnace Installation Process
In-Home Assessment and Sizing
A licensed technician visits your home to evaluate your existing system, ductwork, insulation, and square footage. Proper sizing is critical: an oversized furnace short-cycles and wastes energy, while an undersized unit cannot keep up on the coldest days. We perform a Manual J heat load calculation to determine the exact capacity your home needs.
Written Quote and Equipment Selection
You receive a detailed written quote that includes the furnace unit, all materials, labour, permits, and applicable rebates. We walk you through the options so you can make an informed decision. No pressure, no hidden fees.
Old Furnace Removal
On installation day, our team safely disconnects and removes your old furnace and any outdated components. We handle all disposal and recycling in accordance with Ontario regulations.
New Furnace Installation
Your new furnace is installed with proper gas line connections, electrical wiring, venting, and ductwork modifications as needed. We follow all TSSA codes and obtain the required permits for gas work in Ontario.
Testing and Commissioning
We run the furnace through multiple heating cycles, verify gas pressure, check for leaks, test the thermostat, and ensure every component operates within manufacturer specifications. You receive a full walkthrough of your new system before we leave.
Furnace Installation Rebates and Incentives
Toronto and Ontario homeowners can access thousands of dollars in rebates when upgrading to a high-efficiency furnace. We help you identify and apply for every rebate you qualify for.
Canada Greener Homes Grant
The federal Canada Greener Homes Grant offers up to $5,000 for eligible energy-efficient home upgrades including high-efficiency furnace installations. Requires a pre- and post-retrofit EnerGuide evaluation.
Ontario Energy Programs
Provincial and utility programs through Enbridge and local distributors offer additional rebates for upgrading from standard to high-efficiency furnaces. Rebate amounts vary by program and equipment type.
Manufacturer Rebates
Brands like Carrier, Lennox, and Daikin run seasonal promotions and instant rebates that can be combined with government incentives. We track current manufacturer offers and apply them to your quote automatically.
When all available rebates are combined, homeowners can save $5,000 to $10,000+ on a new high-efficiency furnace installation. Visit our rebates page for current program details, or call us for a personalized rebate estimate.
