Most furnaces in Ontario last 15-20 years with proper maintenance, though this varies based on the unit’s quality, usage patterns, and how well it’s maintained. High-efficiency condensing furnaces may require more frequent maintenance due to their complex heat exchanger design, but they typically last just as long as standard units when properly cared for.
Ontario’s harsh winters put significant stress on heating systems, making regular maintenance crucial for longevity. A furnace that’s serviced annually, has its filter changed regularly, and receives prompt attention for minor issues will consistently reach or exceed its expected lifespan.
If your furnace is approaching 15 years old and requiring frequent repairs, it’s often more cost-effective to replace it with a modern high-efficiency unit, especially given the energy savings and improved reliability you’ll gain.
Furnace installation costs in Ajax typically range from $3,500 to $7,000 depending on the unit’s efficiency, size, and complexity of installation. Basic mid-efficiency units start around $3,500-4,500 installed, while high-efficiency condensing furnaces with advanced features can reach $6,000-7,000 or more for larger homes.
That said, every home is different, and we work with a wide range of budgets. Financing options are available to help make furnace replacement more affordable, and we’ll always provide you with multiple options to fit your needs and budget.

Ajax’s housing mix includes everything from 1960s-era homes in central neighbourhoods to brand new developments in the southeast. Older homes often have original ductwork that may benefit from sealing or modification when installing a new high-efficiency furnace, while newer homes are typically designed with modern HVAC systems in mind.
Many Ajax homes have finished basements where furnaces are located, requiring careful consideration of clearance requirements and venting when upgrading to high-efficiency units. The town’s proximity to Lake Ontario also means slightly milder winter temperatures compared to areas further inland, which can influence furnace sizing decisions.
During Ajax’s cold winters, watch for these warning signs that indicate your furnace needs professional attention: unusual noises like banging, squealing, or grinding; uneven heating where some rooms are much colder than others; frequent cycling on and off; yellow or flickering pilot light flames; and increasing energy bills despite similar usage patterns.
Other red flags include dust or particles being blown from your vents, a burning or metallic smell when the furnace runs, or visible rust or corrosion on the unit itself. Don’t ignore these signs — catching problems early prevents costly emergency repairs and ensures your family stays warm throughout the heating season.
If you notice any of these issues, it’s worth having a TSSA-licensed technician diagnose the problem before it worsens. Many furnace problems start small but can quickly escalate if left unaddressed.
Durham Region’s variable winter weather — from mild days to brutal cold snaps — puts unique demands on your furnace. The frequent temperature swings mean your system cycles more often than in areas with steadier winter temperatures, making annual maintenance even more critical.
Fall maintenance should include cleaning or replacing the air filter, inspecting the heat exchanger for cracks, testing safety controls, checking gas connections for leaks, and ensuring the venting system is clear of obstructions. This is especially important for high-efficiency furnaces with plastic venting that can become blocked by snow or ice buildup.
Don’t wait until the first cold snap to test your system. Schedule maintenance in early fall so any issues can be addressed before you need reliable heat throughout the winter months.
Ontario requires all new furnaces to meet minimum efficiency standards, currently 90% AFUE (Annual Fuel Utilization Efficiency) for most installations. This means replacing an older 80% efficient furnace with a modern unit will provide immediate energy savings, even before considering advanced features like variable-speed blowers or modulating gas valves.
High-efficiency furnaces also qualify for various rebate programs from Enbridge Gas and government efficiency programs. These rebates can offset a significant portion of the upgrade cost, making it more affordable to invest in a premium unit that will provide years of reliable, efficient heating.
When choosing efficiency levels, consider how long you plan to stay in your home and current energy costs. Higher efficiency units cost more upfront but provide greater long-term savings, especially in homes with higher heating demands.
Before calling for service, check these common issues that homeowners can safely address themselves.
Make sure it’s set to Heat, the temperature is above room temperature, and the batteries are fresh. This resolves more calls than you’d expect.
Your furnace has a dedicated circuit breaker in your electrical panel and usually a wall switch nearby. Check both are on.
A clogged filter restricts airflow and can trigger a safety shutoff. If you can’t see light through it, replace it before calling.
High-efficiency furnaces have plastic pipes exiting near the foundation. Snow or ice blocking these causes an automatic shutoff — clear them and restart.
Many furnaces have a safety switch that cuts power if the access panel isn’t fully closed. Make sure it’s secured properly.
If none of the above restore your furnace, it’s time for a licensed technician. David and his crew serve all of Durham Region and respond fast.
