Courtice has grown fast, most of its housing stock ranges from 1980s subdivisions near Townline Road to newer builds pushing east toward Darlington, and a lot of those furnaces are either original equipment approaching the end of their service life or mid-range units that weren’t maintained well by previous owners. David covers all of Courtice and the rest of Durham Region for same-day furnace calls, emergencies, new installations, and annual tune-ups.
Every job below is something David handles personally in Courtice. You’ll get a straight answer on what’s needed before any work begins.
If you’re replacing an aging unit or moving into a newly built home in Courtice’s east-end developments, David sizes the equipment to match your home’s actual heat load, not whatever the previous unit was. A correct installation from day one means lower gas bills and fewer repairs down the road. David carries equipment from leading manufacturers and handles all permits and TSSA registration.
Most furnace repairs come down to a handful of components, igniters, flame sensors, pressure switches, blower motors. David diagnoses the problem during the same visit and, in most cases, repairs it the same day. He stocks common parts on the truck so Courtice homeowners aren’t waiting days for a part order before their heat comes back on.
Many of the detached homes built in Courtice’s older Pebblestone and Prestonvale Road corridors during the late 1980s and 1990s are now on their second furnace, and that second furnace is reaching the point where replacement makes more financial sense than another repair. David gives you a straightforward comparison of repair cost versus replacement value before recommending anything. He won’t push a new furnace if fixing the old one makes sense.
A tune-up each fall means David cleans the burners, checks the heat exchanger for cracks, tests the safety controls, measures combustion efficiency, and replaces the filter if needed. It takes about an hour and it’s the single best thing you can do to extend furnace life and keep your gas bill where it should be. Book before October and you’ll avoid the November rush.
Upgrading from an older 80% AFUE furnace to a 96% or 97% unit can cut your heating costs noticeably over a Courtice winter. These units also run quieter and hold temperature more consistently because of variable-speed blowers. David handles the full swap including any venting changes required when switching from a B-vent to a direct-vent high-efficiency setup. Enbridge rebates may apply depending on current program availability.
When the furnace goes out on a January night and it’s minus fifteen outside, you need someone who answers the phone. David picks up personally. He covers Courtice and all of Clarington for emergency furnace calls and aims to get to you the same day, including evenings. There’s no call centre, no dispatcher, no getting passed around, just David, on the line, sorting out when he can get to you.
I’ve been servicing furnaces in Courtice since 2011, and the pattern I see more than anything is homeowners who got told by the last contractor that they needed a full replacement when a $300 repair would have kept that furnace running for another five years. I won’t do that. If your unit is repairable and the numbers make sense, that’s what I’ll tell you. I answer the phone myself, I do the work myself, and I’ve held TSSA Licence #000398183 the whole time.
Most gas furnaces installed in Ontario last between 18 and 25 years, though the real range is wider than that in practice. A well-maintained mid-efficiency furnace from the early 2000s can still run reliably today. A high-efficiency unit that never got a filter change in its first decade of life might be showing serious wear by year twelve. The equipment matters less than the maintenance history.
Ontario’s climate shortens furnace life compared to milder regions because the equipment runs hard from October through April. That’s six or more months of regular cycling, which adds up on heat exchangers, blower motors, and ignition components. Annual servicing catches the small problems before they become the expensive ones, a cracked heat exchanger identified in October is a much easier conversation than one found at 10 p.m. in February.
The single most effective maintenance step is filter replacement. A clogged filter forces the blower to work harder and raises the temperature inside the heat exchanger above design limits. Do that for a few winters in a row and you’ll shorten the furnace’s life noticeably. A one-inch filter in a typical Courtice home needs changing every one to three months during heating season, depending on how dusty the house is and whether you have pets.
For a straightforward furnace repair on a common issue like a failed igniter, faulty flame sensor, or bad pressure switch, expect to pay somewhere between $150 and $400 all-in depending on the part and the time required. More involved repairs, like a blower motor replacement or a heat exchanger that needs addressing, can run from $400 to $900. These are realistic ranges based on what David typically sees in Courtice homes, not ballpark estimates inflated to make the invoice look like a deal.
A new furnace installation in Courtice typically runs between $3,500 and $6,500, installed and permitted. The spread comes down to a few variables: the efficiency rating you choose, whether the existing venting can stay or needs to change (particularly if you’re upgrading from a standard-efficiency unit to a high-efficiency condensing furnace), the size of the home, and whether there’s any ductwork modification needed. Larger two-storey homes built in Courtice’s newer subdivisions near Trulls Road or Prestonvale sometimes need duct balancing work at the same time.

Courtice sits in the western part of Clarington and has seen two distinct waves of residential development. The first wave ran through the 1980s and into the mid-1990s, producing large subdivisions of detached and semi-detached homes roughly between Townline Road and Courtice Road, many of them with original or once-replaced mid-efficiency furnaces. The second wave, still ongoing, pushed east toward Darlington and south toward the lake, bringing newer builds with high-efficiency systems already installed but sometimes with oversized equipment or improper venting that wasn’t caught during the build.
In the older stock, David frequently runs into furnaces that were replaced once already, often with a builder-grade unit that was sized to match the original rather than recalculated for the home’s actual envelope. Homes in Courtice built before 2000 were typically less well-insulated than today’s builds, and some have since had attic or wall insulation upgraded without the HVAC ever being revisited. That means the furnace can be oversized for how the house actually performs now, which causes short-cycling and wear on the heat exchanger.
In the newer east-end developments, the common issues David sees are inadequate commissioning after installation, high-efficiency furnaces that weren’t set up for the correct airflow or weren’t balanced across zones properly. These homes can have cold spots on the second floor or excessive temperature swings that aren’t a furnace failure at all, just a setup problem. It’s worth getting a second opinion before assuming the equipment needs replacement.
The clearest sign is a furnace that cycles on, runs for a short time, then shuts off before reaching the set temperature. This short-cycling is usually caused by one of three things: a dirty filter restricting airflow and triggering the high-limit safety switch, a faulty flame sensor that’s not reading the burner properly, or a heat exchanger that’s cracked and causing the furnace to shut itself down as a safety measure. Each of those has a different repair path and a very different cost, which is why a proper diagnosis matters before anyone replaces anything.
Unusual sounds are another reliable indicator. A grinding or scraping noise from the blower compartment usually points to a worn blower wheel or failing motor bearing. A loud bang or pop when the burner fires is often delayed ignition caused by gas buildup in the combustion chamber, which stresses the heat exchanger over time. A high-pitched squeal typically means a belt or bearing on its way out. These aren’t noises to wait on.
In Courtice’s colder winters, when temperatures drop into the minus teens for stretches at a time, a furnace that’s losing efficiency will show up clearly on your gas bill before it shows up as a complete failure. If your heating costs jumped noticeably this year without a corresponding change in how cold the winter was, that’s worth investigating before the unit gives out entirely.
Durham Region’s heating season is long and the temperature swings are significant. Courtice regularly sees overnight lows below minus fifteen in January and February, which means your furnace doesn’t get much of a rest for months at a time. The most practical thing you can do is schedule a tune-up in September or early October, before the heating season starts in earnest. That gives David time to identify any parts showing wear and replace them before they fail on a cold night.
Sealing your home also makes a real difference. Courtice’s older homes often have gaps around basement rim joists, unsealed attic hatches, and drafty window frames that force the furnace to run longer cycles to maintain temperature. Improving air sealing and attic insulation reduces the heating load on the furnace, which reduces wear and extends equipment life. It’s not a furnace issue, but it’s connected to how hard the furnace has to work.
A programmable or smart thermostat is worth the investment in Durham Region’s climate. Setting the temperature back to 18°C overnight and during the day when the house is empty saves a meaningful amount of gas over a full heating season without putting any additional stress on the equipment. Modern furnaces handle temperature setbacks without issue.
Carbon monoxide is the primary safety concern with any gas furnace. CO is odourless, colourless, and produced when combustion is incomplete, which can happen through a cracked heat exchanger, a blocked flue, or a furnace that’s running outside its design parameters. Ontario law requires CO detectors on every level of the home, and David checks CO levels as part of every annual tune-up. If your CO detector alarm goes off, leave the home immediately and call 911 before calling anyone else.
All furnace work in Ontario requires a licensed technician. TSSA Licence #000398183 is David’s verifiable credential, searchable through the TSSA public registry. Any contractor who can’t provide a licence number shouldn’t be working on your gas appliances. This isn’t a formality, it’s how Ontario ensures the work is done to code and that the homeowner is protected if anything goes wrong.
On the efficiency side, Enbridge Gas periodically offers rebates for homeowners who upgrade to high-efficiency equipment. The programs change, but if you’re replacing an 80% AFUE unit with a 96% or higher model, it’s worth checking current Enbridge incentives before you commit to equipment. David can tell you what’s available at the time of your quote and factor it into the comparison between keeping your existing unit and replacing it.
Checking the simple things before calling saves time for everyone, these five steps clear up a surprising number of no-heat calls.
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 gets your heat back on, it needs a licensed technician. David serves all of Durham Region and picks up the phone personally.
Once a year, every year, in the fall before the heating season starts. Ontario’s winters are long and cold enough that your furnace runs hard from October through April without much of a break, and that kind of sustained use catches up to equipment that’s not being maintained. An annual tune-up in September or early October means David checks the heat exchanger for cracks, cleans the burners, tests the ignition system, measures combustion efficiency, and makes sure all the safety controls are working before you actually need the heat. Courtice homeowners who skip this for a few years in a row tend to call in January when something fails, at which point the diagnosis is more expensive and the wait is longer. A September appointment takes about an hour and is the cheapest thing you can do to keep a furnace running for its full lifespan. If your furnace is approaching fifteen years old, annual servicing also helps you decide with confidence whether you’re maintaining a unit that has years left in it or throwing money at something that’s near the end.
The answer depends on three things: the age of the unit, the cost of the repair, and the efficiency of what you have versus what you’d replace it with. A furnace under twelve years old with a repair bill under $500 is almost always worth fixing. A furnace over eighteen years old facing a $900 heat exchanger repair is much harder to justify when a new high-efficiency unit will cost less to run and comes with a warranty. The grey zone is the middle years, roughly twelve to eighteen, where the repair cost relative to replacement cost matters most. A rough rule David uses: if the repair costs more than half of what a new furnace would cost installed, and the unit is over fifteen years old, replacement is the better financial decision in most cases. But that calculation changes based on your specific unit, how it was maintained, and what the repair actually is. David won’t push replacement when repair makes more sense, he’ll walk you through the numbers and let you decide. In Clarington, where David has been working since 2011, the most common mistake he sees is homeowners replacing a furnace that had another five good years in it because a previous contractor scared them into it.
For a Durham Region home, a 96% AFUE high-efficiency furnace is the right choice for most homeowners replacing an older unit. Here’s why the number matters: an 80% AFUE furnace sends 20 cents of every dollar you spend on gas out through the flue. A 96% unit loses only 4 cents. Over a Durham Region heating season that runs six months or more, that gap adds up on your Enbridge bill. The payback period on the price difference between an 80% and a 96% unit in Courtice is typically three to six years, depending on how much you heat the home and what gas prices are doing. There’s also a physical consideration: upgrading to a high-efficiency condensing furnace means switching from a B-vent flue to direct-vent plastic piping that exits through the wall or foundation, which changes the installation requirements. David handles that switch as part of the installation and makes sure the venting is done to code. For most Courtice homeowners in a standard detached or semi-detached home, a 96% two-stage furnace with a variable-speed blower hits the right balance of efficiency, comfort, and cost.
A standard furnace replacement in a Courtice home typically takes three to five hours from start to finish. That includes removing the old unit, installing the new furnace, connecting the gas line, making any venting changes, wiring up the thermostat, and testing the system through a full heating cycle before David leaves. More involved jobs take longer. If the ductwork needs modifications, if the venting setup is complicated, or if there’s any electrical work required, the job can extend to six or seven hours. David books enough time to do it properly rather than rushing to get to the next call. What you should expect on installation day: David arrives with the equipment and all the materials needed to complete the job. You won’t have a half-finished furnace while he goes to pick up a fitting. The home is left without heat for the duration of the installation, so if you’re booking in cold weather, it’s worth knowing the timing. In most cases, heat is restored the same day, usually by late afternoon at the latest.
Yes. David services all major furnace brands found in Courtice and Clarington homes, including Carrier, Lennox, Trane, York, Goodman, Bryant, American Standard, Napoleon, and others. The diagnostic process is largely the same across brands, the components that fail most often are common to all of them, and David stocks the most frequently needed parts on the truck. For less common parts on older or less common brands, he’ll source them quickly rather than waiting on a slow order. The only situation where brand matters is installation, David recommends specific brands based on reliability data, parts availability, and warranty terms, and he’ll tell you which ones he’s had the best long-term results with in Durham Region homes. He’ll also tell you which brands he’d steer away from and why. If you’ve got a specific brand you’ve had good experience with, that’s a fair conversation to have before picking equipment.
Cold air from the vents when the furnace is running usually points to one of a few specific problems. The most common is a faulty flame sensor, the sensor that tells the furnace the burner has actually lit. When it’s dirty or failing, the furnace starts, doesn’t confirm ignition, and shuts the burner off as a safety measure, leaving the blower running on its own and pushing cold air through your vents. A cleaning or replacement fixes this quickly. The second common cause is overheating due to a clogged air filter. The furnace fires up, the restricted airflow causes temperatures to rise too fast inside the heat exchanger, and the high-limit switch shuts the burner off while the blower keeps running. Check your filter first, if it’s badly clogged, replace it and see if normal heating resumes. A third possibility is a problem with the gas valve or ignition control board, both of which require a proper diagnosis before replacing. In Courtice during winter, cold air from the vents is worth calling about the same day rather than hoping it resolves itself.
Leave the house immediately. Don’t turn any lights on or off, don’t use your phone inside, don’t operate any switches. Get everyone out, leave the door open as you go, and call Enbridge Gas from outside or from a neighbour’s home. The Enbridge emergency line is 1-866-763-5427 and they respond around the clock. Let them attend first, they’ll confirm whether there’s a leak, shut off the gas if needed, and clear the home before anyone else goes in. After Enbridge has cleared the scene and the gas supply is confirmed safe, David can come in to find the source and repair it. A gas smell isn’t always a furnace problem specifically, it can be a fitting on the gas line, a valve connection, or an issue with another appliance, but the response is the same regardless of the source. Don’t try to find the leak yourself and don’t restart the furnace until a TSSA-licensed technician has inspected the system and confirmed it’s safe to operate.
Yes. David works with financing options for homeowners who need a new furnace but don’t want to cover the full cost upfront. A new furnace installation in Courtice typically runs between $3,500 and $6,500 depending on the equipment and the specifics of the job, and financing lets you spread that cost over monthly payments at a manageable rate. It’s worth asking about current terms at the time of your quote since rates and program availability change. If you’re also looking at Enbridge rebates for a high-efficiency upgrade, those can reduce the financed amount, which lowers your monthly payment. David will walk you through what’s available when he gives you the quote. There’s no pressure to finance, plenty of homeowners pay for installation outright, but the option is there if it makes the decision easier. The best way to know what your specific job will cost is to get a free quote from David, no pressure, no obligation.
“Furnace died on a Thursday night in February. David was at our Courtice house by noon the next day, diagnosed a cracked heat exchanger, and had a new unit installed by 4 p.m.”
“I called David because my furnace was short-cycling and I’d already had two other guys tell me I needed a full replacement. David came out, cleaned the flame sensor, checked the filter situation, and had it running properly in under an hour. He explained exactly what was causing it and what to watch for going forward. Cost me $175. No upsell, no pressure.”
“Got three quotes for a new furnace in our Courtice home. David’s price was fair and the quote matched the invoice exactly, which wasn’t true for one of the other contractors. He put down floor covers before carrying the old unit out and swept up before he left. Small thing, but it stood out.”
