Clarington’s housing stock runs from Bowmanville’s century homes to the newer subdivisions pushing west through Courtice, and the furnace demands in those two worlds are completely different, David has been working through all of it since 2011. He covers every corner of the Municipality of Clarington, same day when you need it most.
From a no-heat call at midnight in Newcastle to a planned furnace swap in a Bowmanville semi, David handles every job himself.
David sizes every new furnace to the actual home, square footage, insulation, ceiling height and window area all factor in. Clarington’s newer Courtice subdivisions often have open-concept layouts that need careful airflow planning. You get the right unit for your house, not the easiest one to sell you.
David carries common replacement parts on the truck, ignitors, pressure switches, limit controls, so most repairs wrap up on the first visit. He tells you straight what’s failed, what it costs to fix it, and whether fixing it makes sense given the age of the unit. No second opinion needed.
Many of Clarington’s older Bowmanville homes still run mid-efficiency furnaces installed in the late 1990s or early 2000s. When the cost of keeping one of those going starts to outweigh a replacement, David gives you a clear comparison, repair costs versus what a new high-efficiency unit would save you annually. He replaces the furnace, not the ductwork you don’t need to change.
David runs a full combustion analysis, checks the heat exchanger for cracks, cleans the burners, tests all safety controls and measures airflow at each register. A tune-up booked in September or October costs a fraction of what an emergency call costs in January. It also keeps your manufacturer warranty valid.
Moving from an 80% AFUE furnace to a 96% or 98% unit cuts the gas you burn for the same heat output significantly. David reviews your current setup, calculates the load correctly, and installs the new unit with proper venting, two-pipe PVC on a high-efficiency system, not a modification of the existing metal flue. You also get help identifying any rebates you’re eligible for through Enbridge.
When it’s minus fifteen and your furnace shuts down, David picks up the phone. He covers all of Clarington including Newcastle, Orono and the rural areas east of Bowmanville where other contractors often won’t go. You talk to David directly, not a dispatcher who’ll schedule someone for tomorrow morning.
I’ve been working in Clarington since 2011, I know the older brick homes around Bowmanville’s historic core, I know the newer builds out in Courtice, and I know where corners get cut during installation in both. Every quote I give you is based on what your home actually needs, and I’ll tell you plainly if a repair is the smarter move over a replacement.
A gas furnace in Ontario typically runs for 18 to 25 years when it’s serviced annually and the filter’s changed regularly. The lower end of that range usually comes from furnaces that ran for years without maintenance, dirty heat exchangers crack faster, and ignitors burn out sooner when they’re cycling through on and off more than they should. The upper end is achievable, but it requires attention.
Ontario’s climate puts real stress on heating equipment. Clarington sits in a zone where temperatures drop into the minus twenties in January and February, and a furnace running flat out for weeks at a time is under more strain than one in a milder climate. Annual tune-ups matter more here than they would in, say, southern Ontario’s milder pockets. A combustion analysis in the fall catches small problems before they become mid-January failures.
High-efficiency condensing furnaces, the 90% AFUE and up models, add a secondary heat exchanger and a condensate drain to the picture. Those components need attention too. The condensate line can freeze in improperly vented systems, and the secondary heat exchanger is more susceptible to cracking from acidic condensate buildup if the system isn’t cleaned regularly. Build a furnace service into your September routine and you’ll get close to that 25-year end of the range.
A gas furnace repair in Clarington typically runs between $150 and $650, depending on what’s failed. A new ignitor or pressure switch sits at the lower end. A draft inducer motor or a heat exchanger replacement pushes toward the top, and at that price point, David will compare the repair cost against a new unit so you’re making an informed call rather than pouring money into an old furnace out of habit.
A new furnace installation in Clarington runs from approximately $3,200 to $5,500 for most homes, installed. The spread comes from unit efficiency (80% AFUE vs 96% AFUE), brand, BTU capacity, and the complexity of the installation, a straight swap in a house with good existing ductwork and an accessible mechanical room costs less than a first-time installation or a job where the venting needs rerouting. David doesn’t charge a diagnostic fee when you move forward with the repair or installation.

Clarington covers a large geographic area with a genuinely varied housing stock. Bowmanville’s older neighbourhoods east of Liberty Street contain a lot of homes built in the 1950s through 1980s, brick and frame construction with older ductwork systems designed for the larger, less efficient furnaces of that era. When David replaces a furnace in one of those homes, he checks the duct sizing carefully. Installing a modern variable-speed unit into an undersized duct system causes noise, pressure problems and premature equipment failures.
The subdivisions that grew through Courtice and northeast into Newcastle during the 1990s and 2000s present a different set of issues. Many of those homes were built with builder-grade furnaces and mid-range ductwork. Those units are now 20 to 30 years old and heading toward the end of their usable life. Homeowners in these areas often call David after a second or third repair in a season, and that’s usually the right time to look at replacement seriously.
Newcastle and Orono also include a number of rural properties on acreage, larger square footage, sometimes older forced-air systems with minimal insulation upgrades since original construction. David accounts for envelope performance when sizing a replacement unit for those homes rather than simply matching the BTU output of the old furnace, which is often oversized relative to what the house actually needs once you factor in modern insulation values.
A furnace that short-cycles, starts, runs for a few minutes, shuts off before the house reaches temperature, then repeats, is usually telling you something specific. The most common causes are a dirty or blocked air filter choking airflow, a failing flame sensor letting the burner light but not confirming it, or a cracked heat exchanger causing the high-limit control to trip as a safety measure. Each one has a different fix and a different cost, so the symptom alone doesn’t tell you the repair price, but it does tell you something is wrong.
Unusual noises matter. A high-pitched squeal usually points to a worn inducer motor bearing. Banging on startup is often a delayed ignition, gas builds up before the ignitor fires, then combusts harder than it should. That’s worth addressing promptly because it stresses the heat exchanger over time. A rattling sound from the cabinet can be as simple as a loose panel or as significant as a failing blower wheel.
In Durham Region’s winters, a furnace that’s working harder to maintain temperature, where your gas bill is noticeably higher than the previous winter without a corresponding change in weather, often signals a dirty heat exchanger, degraded combustion, or a refrigerant-side issue if it’s a heat pump hybrid setup. Clarington homeowners running older 80% AFUE units tend to see this pattern in the years before the furnace fails entirely. It’s worth getting a combustion analysis rather than guessing.
Durham Region’s heating season runs roughly from October through April, with the coldest sustained stretches in January and February. Your furnace filter needs checking every 60 to 90 days during that window, not just once a year. A 1-inch pleated filter that’s been in place since October is often fully loaded by December. A clogged filter doesn’t just reduce efficiency, it can cause the heat exchanger to overheat and trip the high-limit safety, which is one of the most common reasons furnaces stop working mid-winter.
If your home has a high-efficiency furnace with PVC intake and exhaust pipes exiting through the foundation wall, clear snow away from those terminations after heavy snowfall. Clarington gets significant lake-effect snow accumulation in some winters, and a blocked exhaust pipe causes an automatic shutdown. It’s a two-minute check that can save you a service call. Also keep the area around your outdoor air intake clear of leaves and debris in the fall before the heating season starts.
A programmable or smart thermostat helps your furnace work in a steadier rhythm rather than recovering from a large temperature setback. A 2-degree setback overnight is easier on the equipment than dropping the house to 16°C and asking the furnace to recover by 7 a.m. David can advise on thermostat settings that match how your specific furnace and home perform together.
In Ontario, gas furnace work requires a licensed technician under TSSA regulations. David holds TSSA Licence #000398183, which you can verify directly with the TSSA. That licence covers gas appliance installation, repair and maintenance, the full scope of what he does. Hiring an unlicensed contractor for gas work isn’t just a code issue; it also voids your home insurance coverage for any resulting damage.
Carbon monoxide is the safety concern that matters most with a gas furnace. A cracked heat exchanger allows combustion gases to mix with circulating air. CO is odourless and colourless, and symptoms of low-level exposure, headache, nausea, fatigue, mimic other illnesses. Every home with a gas furnace should have a working CO detector installed within 1.5 metres of the sleeping area, as required by Ontario’s Fire Code. If your CO alarm sounds, leave the house and call 911 before calling David.
On the efficiency side, Enbridge Gas offers rebates for qualifying high-efficiency furnace installations in Ontario. The rebate amounts change annually, but a 96% or 98% AFUE unit has typically qualified for meaningful savings. David will tell you what’s currently available at the time of your quote. The Canada Greener Homes Grant program has also covered heat pump upgrades for homeowners who go that route. Even without rebates, the long-term gas savings from moving off an 80% unit add up quickly in Clarington’s heating climate.
Checking the simple things before calling saves time for everyone, run through these five steps first.
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 work, it needs a licensed technician. David serves all of Clarington and Durham Region and picks up the phone himself.
Once a year, before the heating season starts, September or early October is the right window for most Clarington homeowners. Ontario’s heating season is long and cold, and a furnace that runs hard from November through March needs to start that run in good condition. An annual tune-up covers combustion analysis, heat exchanger inspection, burner cleaning, flame sensor check, blower motor inspection, flue gas measurement and a full test of all safety controls. That’s not a service you can skip and make up for with a bi-annual visit, a cracked heat exchanger or a failing ignitor doesn’t wait for a convenient time to cause a problem. Homeowners who service annually also maintain their manufacturer warranty, which most brands require. If you bought your furnace new and haven’t had it looked at since installation, book one this fall.
The repair-versus-replace decision comes down to three things: the age of the unit, the cost of the repair, and how many repairs it’s already needed. A furnace under 15 years old with a first-time failure is almost always worth repairing, a $300 fix on a 10-year-old furnace is straightforward math. A furnace over 20 years old that needs a heat exchanger replacement or a draft inducer motor is a different conversation. Those repairs often run $600 to $900, and you’re putting that money into equipment that may fail again in a year or two. David will give you both options with honest numbers so you can decide. He won’t push replacement when a repair makes sense, that’s not how he builds a business. But he also won’t recommend a repair that’s only buying you one more season when the smarter spend is a new unit that comes with a warranty and lower gas bills.
For a Durham Region home, a 96% AFUE furnace is the sweet spot for most people, and it’s what David installs most often in Clarington. The difference between an 80% and a 96% unit means 16 cents of every dollar you spend on gas is no longer going up the flue, and in Durham Region’s winters, that adds up to real money. The 80% models are still code-legal but they require a metal B-vent flue, which can complicate replacements in older Bowmanville homes where the existing chimney is shared with a water heater. The 96% and 98% units vent through two-inch PVC pipes out the side of the house, which simplifies the venting significantly. The incremental cost of the higher-efficiency unit typically pays back through gas savings within five to seven years, and the rebate from Enbridge for qualifying equipment can shorten that payback period further. David will walk through the numbers specific to your home and your current gas usage.
A standard furnace replacement in a Clarington home takes four to six hours from the time David arrives to the time the new unit is running and the old one is removed. That covers disconnecting and removing the existing furnace, positioning and securing the new unit, making gas and electrical connections, installing new venting if needed, setting up the condensate drain on a high-efficiency system, commissioning the furnace with a combustion analysis, and testing every zone and thermostat connection. More complex jobs, first-time installations, significant ductwork modifications, or homes where the mechanical room requires reconfiguration, can run a full day. David gives you a realistic time estimate during the quote visit, not an optimistic one that gets revised on the day. Your heat is back on before he leaves.
Yes, David services all major gas furnace brands found in Clarington homes, including Lennox, Carrier, Bryant, Trane, American Standard, Goodman, Amana, Napoleon, York, Keeprite, Rheem and Payne. He also services older units from manufacturers that have since been rebranded or discontinued. Brand isn’t the limiting factor on whether a repair is possible, parts availability is, and David checks that before committing to a repair timeline. For installs, he works with a range of brands and will recommend the unit that fits your home’s requirements and your budget rather than whatever has the highest margin. If you’ve got a furnace with an unusual brand or an older unit you’re not sure about, call him and describe what you’ve got, he’ll tell you straight what’s serviceable and what isn’t.
Cold air from a running furnace usually points to one of four things. First, check that your thermostat is set to Auto, not Fan, if it’s set to Fan only, the blower runs continuously whether the burner is firing or not. Second, a dirty air filter can cause the high-limit control to trip, which shuts off the burner but lets the blower keep running to cool the heat exchanger, replace the filter, reset the furnace and see if it recovers. Third, a failed ignitor means the furnace tries to start, the blower comes on in anticipation, but no burner lights, you get moving air with no heat. Fourth, a flame sensor that’s corroded or dirty can light the burner briefly but fail to confirm the flame, causing the gas valve to shut immediately while the blower continues. Three of those four issues are relatively straightforward repairs. The fourth, a cracked heat exchanger triggering the limit control repeatedly, is more serious and warrants a thorough inspection before continuing to run the furnace. Call David and describe what you’re seeing; he’ll help you figure out which category you’re dealing with before he arrives.
Leave the house immediately, don’t stop to open windows, don’t turn light switches on or off, don’t use your phone inside the building. Once you’re outside, call 911 and then Enbridge Gas Emergency at 1-866-763-5427. Let them clear and assess the situation before anyone re-enters. A gas smell can mean a leak in the supply line, a failed gas valve, or a connection that’s worked loose, none of those are situations where you troubleshoot yourself. After Enbridge has cleared the scene and confirmed the source, David can assess the furnace itself and repair or replace whatever component failed. Ontario law requires TSSA-licensed technicians for all gas appliance work, which is exactly why David carries Licence #000398183. Do not let anyone who isn’t licensed touch the gas components on your furnace, regardless of what they quote you or how fast they say they can be there.
Yes, financing options are available for furnace installations in Clarington to help spread the cost of a new unit over time. A new furnace is a significant home investment, typically $3,200 to $5,500 installed depending on the unit and the complexity of the job, and financing lets you get the right equipment for your home without having to compromise on efficiency or quality to hit a lower upfront number. Available financing terms and rates are worth discussing at the time of your quote, as options can vary. David will walk you through what’s available when he comes to assess your home. It’s also worth asking about Enbridge rebates at the same time, a qualifying high-efficiency unit can reduce your net cost before financing even enters the picture.

“Furnace died on a Tuesday night in January. David was at our Bowmanville house by 9 a.m. the next morning, replaced the ignitor, and had heat running before noon.”
“I called David because our 22-year-old Lennox was short-cycling. He came out, ran a combustion analysis, showed me the cracked heat exchanger on his camera, and gave me the repair cost versus a new unit side by side. He was straightforward about the fact that repairing it made no sense at that age. We went with a new Carrier 96% AFUE and he had it installed and running that same week. No upselling, no drama.”
“Quoted me $3,800 installed, that’s exactly what I paid, not a dollar more. He put down covers on the floors in the utility room and hallway, cleaned up after, and took the old furnace with him. I’ve had contractors leave me cleaning up for an hour after they’ve gone. That didn’t happen here.”
