Clarington’s mix of 1980s and 1990s subdivisions in Bowmanville and Courtice, newer builds in Newcastle, and rural properties throughout the municipality means heat pump jobs here vary widely, from straightforward ducted replacements to first-time installations in homes that were built around gas furnaces and never had a heat pump at all. David covers all of Clarington with same-day and emergency availability, and he picks up the phone himself.
From a brand-new installation to an emergency repair in the middle of a February cold snap, David handles every aspect of heat pump work across Clarington.
Many Clarington homes built through the 1980s and 1990s in Bowmanville were designed around mid-efficiency gas furnaces, so adding a heat pump means David reviews the existing duct sizing before recommending equipment, an undersized duct system will choke airflow and hurt efficiency regardless of how good the unit is. He’ll spec the right capacity for your home’s footprint and walk you through the install from start to finish.
A heat pump that’s short-cycling, blowing lukewarm air, or running constantly but not reaching temperature needs a proper diagnosis, not a guess. David stocks common parts on his truck so most repairs wrap up in a single visit. He’ll tell you exactly what failed and why before touching anything.
If your heat pump is past 15 years or repairs are stacking up, David’ll give you a straight assessment of whether replacing it makes financial sense versus spending another season patching it. He won’t push a replacement to pad a job, if a repair gets you another three solid years, he’ll say so. When replacement is the right call, he’ll recommend a unit sized and rated for Ontario winters.
A heat pump works year-round in a way that a furnace or air conditioner alone doesn’t, which means the wear cycle is different. An annual tune-up covers the coils, refrigerant charge, electrical connections, defrost cycle, and filter, the things that quietly degrade efficiency before they become a breakdown. Book it in the fall before heating season hits.
Older single-stage heat pumps installed before 2015 run at full capacity or not at all. A variable-speed cold-climate unit modulates output to match what your home actually needs, which cuts both your hydro bill and the noise. David can walk you through the efficiency ratings and payback periods without the sales pitch.
Clarington winters routinely drop below the threshold where older heat pumps struggle, and a unit that quits at minus 15 isn’t something you can wait a week to fix. David covers Bowmanville, Courtice, Newcastle, and the rural stretches of Clarington for emergency calls. Call (416) 508-4585 and he picks up, not a dispatcher, not a voicemail.
I’ve been working in Clarington since 2011, and what I see most often are homes in Bowmanville and Courtice where the original furnace setup was never built with a heat pump in mind, the duct sizing is off, the electrical panel needs attention, or nobody’s touched the system in a decade. I give every homeowner a clear picture of what’s there before we talk about what to do next. You won’t get a quote that changes once I’m on the job.
A well-maintained heat pump typically runs 15 to 20 years in Ontario. Cold-climate models with variable-speed compressors installed in the last five years tend to sit closer to the upper end of that range, they’re built for the duty cycle Ontario weather demands. Older single-stage units installed before 2010 often start declining around the 12-to-15-year mark, especially if they’ve never had a proper annual tune-up.
What shortens a heat pump’s life most in this climate is deferred maintenance. Ontario’s freeze-thaw cycles put stress on the outdoor coil, and a defrost cycle that isn’t working correctly will push ice into the coil and damage it over a single winter season. Refrigerant leaks left unaddressed force the compressor to work harder than it should, and a compressor that runs hot runs out early.
The single biggest maintenance point for Ontario heat pumps is the coil cleaning in the fall. Cottonwood and debris from summer accumulate on the outdoor coil through July and August. By October that debris is restricting airflow right when you need the unit to start working hard. David cleans and inspects the coil as part of every annual tune-up, it’s not complicated, but it makes a real difference to both efficiency and lifespan.
A standard heat pump installation in Clarington, replacing an existing system where the ductwork is already in reasonable shape, typically runs between $4,500 and $8,500 installed, depending on equipment size, efficiency rating, and whether any electrical panel work is needed. Cold-climate models rated for operation down to minus 25°C sit at the higher end of that range. A straightforward heat pump repair, a faulty capacitor, contactor, or defrost control board, usually lands between $200 and $600 in parts and labour.
What drives the variation in installation cost is mostly three things: the capacity of the unit required for your home’s square footage, whether the existing air handler is compatible or needs replacement, and what condition the electrical service is in. Homes in older Bowmanville subdivisions sometimes need a panel upgrade before a heat pump can be added safely, that’s a separate cost David’ll flag before any work begins.

The Municipality of Clarington covers a large geographic area, Bowmanville, Courtice, Newcastle, Orono, and significant rural and agricultural land stretching north. The housing stock reflects that range. Courtice, which borders Oshawa to the west, has a high concentration of 1980s and early 1990s subdivisions built when natural gas was cheap and nobody was thinking about heat pumps. Most of those homes have existing forced-air systems with ductwork that was sized for a gas furnace’s higher-temperature supply air, not the lower-temperature airflow a heat pump produces.
That duct mismatch is one of the most common issues David encounters in Clarington. A heat pump running through undersized ducts will struggle to move enough air volume to heat the home effectively, even if the unit itself is perfectly sized. Before recommending equipment, David checks the existing duct cross-section against the airflow requirements for the proposed unit. It’s a step that a lot of contractors skip, and it’s why some heat pump installations underperform from day one.
Newcastle and the newer Bowmanville subdivisions east of Green Road have a different profile, homes built from the mid-2000s onward tend to have better insulation and more correctly sized ductwork, making them strong candidates for high-efficiency cold-climate heat pumps. Rural properties in Clarington present their own considerations: propane-heated homes where the owner wants to reduce fuel costs, or homes that rely on baseboard electric heat and are looking at ductless mini-split heat pumps as an upgrade. David handles all of these scenarios across the municipality.
The clearest warning sign is a heat pump that runs constantly without reaching the thermostat setpoint. In Ontario winter conditions, this sometimes gets chalked up to the cold, but if the unit was keeping up last January and isn’t this year, something has changed. Low refrigerant charge is the most common cause, followed by a dirty or blocked outdoor coil. Both are repairable and both get worse the longer they’re ignored.
Unusual noises are another reliable indicator. A grinding noise from the outdoor unit usually points to a failing fan motor or bearing. A clicking or rattling sound that appears and disappears can indicate a loose contactor or a reversing valve that’s starting to stick. In Durham Region’s freeze-thaw shoulder seasons, a heat pump that’s sluggish in the morning and recovers by midday often has a defrost cycle issue, the coil is icing up overnight and the defrost board isn’t clearing it efficiently.
Short-cycling, the unit turning on and off every few minutes without completing a full heating or cooling cycle, puts significant stress on the compressor and drives up electricity costs. It’s usually caused by a refrigerant issue, an oversized unit that was never properly sized to the home, or a control board fault. Any of these need a technician’s diagnosis rather than a reset.
Durham Region sees genuine winters. January and February temperatures regularly hit minus 15°C to minus 20°C, which pushes older heat pumps into supplemental heat territory. If your system defaults to electric resistance backup heat during cold snaps, you’ll notice it on your hydro bill. A cold-climate heat pump rated to minus 25°C operates at full efficiency down to much lower temperatures and relies on backup heat far less often, which is the primary financial argument for upgrading from an older unit when the time comes.
On the operational side, the biggest efficiency gains come from consistent thermostat management. Heat pumps work most efficiently when they maintain a stable temperature rather than recovering from large setbacks. A drop of two or three degrees overnight is fine. Setting the thermostat to 15°C when you leave for work and asking the heat pump to recover to 21°C when you get home forces it into a prolonged high-demand run that burns electricity and stresses the compressor. A programmable or smart thermostat with modest setbacks is the right approach for this climate.
Keep the outdoor unit clear of snow and ice accumulation in winter. A heat pump needs unobstructed airflow across the outdoor coil to function, if the unit is buried in a snowdrift or has ice building up around the base, performance drops immediately. The defrost cycle handles frost on the coil automatically, but it can’t deal with a unit that’s half-buried in a drift. Clear it out and call if the ice isn’t clearing on its own.
Heat pumps themselves don’t produce combustion gases, there’s no carbon monoxide risk from the heat pump unit. If your home also has a gas furnace that works in tandem with the heat pump as a dual-fuel system, the furnace side is still subject to TSSA regulations and should be inspected annually. David holds TSSA Licence #000398183, which covers both the refrigerant side of heat pump work and any gas appliance work in a dual-fuel setup, you’re dealing with one licensed technician for the whole system.
On the rebate side, Ontario homeowners can access the Canada Greener Homes Grant and associated financing programs for qualifying heat pump installations. Enbridge also offers rebates for homeowners switching from gas to an electric heat pump system. Eligibility depends on the equipment’s efficiency ratings and your existing heating setup. David can tell you which units qualify and what documentation you’ll need, the rebate landscape changes, so it’s worth asking at the time of your quote.
Efficiency-wise, the SEER2 and HSPF2 ratings on modern cold-climate heat pumps represent a meaningful leap over equipment from even five years ago. A unit with an HSPF2 rating above 9 will outperform older systems substantially in Ontario’s heating-dominated climate. If your current heat pump is a pre-2015 single-stage unit, an efficiency upgrade isn’t just about comfort, the operating cost difference often justifies the replacement within five to seven years.
Checking the simple things before calling saves time for everyone, run through these before you pick up the phone.
Heat pumps require the thermostat to be set to Heat, and the temperature must be above what the room currently is. Also confirm the system mode isn’t set to Emergency Heat unless needed. Emergency Heat bypasses the heat pump and runs electric resistance backup only, which is expensive and not meant for everyday use.
Heat pumps have two circuit breakers, one for the air handler inside and one for the outdoor unit. Both must be on. A tripped breaker on the outdoor unit will leave the air handler running but blowing unheated air. Reset any tripped breaker once. If it trips again immediately, stop and call David.
Some frost on the outdoor unit is normal in winter, the defrost cycle should clear it every 30 to 90 minutes. A unit completely encased in ice is not normal and indicates a defrost issue. Don’t chip at it. Turn the system off and call Cassar, chipping the coil causes more damage than the ice does.
A blocked filter forces the heat pump to work harder and can trigger safety shutoffs that cut the unit off entirely. Pull the filter, check it, and replace it if it’s grey and packed. If the unit starts working normally after a fresh filter goes in, change it monthly during heavy-use periods rather than quarterly.
If your heat pump is blowing cool air in heating mode, the reversing valve may be stuck or the thermostat may be sending the wrong signal. The reversing valve is the component that switches the system between heating and cooling modes. When it sticks mid-position or fails to shift on command, the unit runs but doesn’t heat. This needs a technician.
If none of the above resolved it, the system needs a licensed technician. David covers all of Clarington and Durham Region and picks up the phone himself, call now and you’ll speak to the person doing the work.
Yes, modern cold-climate heat pumps work reliably in Ontario winters, including the stretches where Clarington sees minus 15°C to minus 20°C for days at a time. The key word is “modern.” Older standard heat pumps installed before roughly 2015 were typically rated to around minus 10°C before efficiency dropped significantly, which gave heat pumps a reputation for struggling in Ontario. Cold-climate units available today, models like the Mitsubishi Hyper Heat or Bosch IDS series, are rated to minus 25°C and maintain a useful coefficient of performance well into minus 20°C territory. That means they’re extracting meaningful heat from outside air even during Clarington’s worst cold snaps rather than running purely on expensive electric backup. If you’re looking at a heat pump for Ontario use, the efficiency rating at low ambient temperatures is the number that matters, not just the headline SEER or HSPF rating.
It depends on a few things I’d look at before giving you a recommendation: what your current gas costs are, how old your furnace is, whether your electrical panel can support a heat pump, and whether you want to eliminate gas entirely or run a dual-fuel setup. A dual-fuel system, heat pump for moderate temperatures, gas furnace for deep cold, often makes the most financial sense for existing Clarington homes that already have gas infrastructure. The heat pump handles the bulk of the heating season efficiently, and the furnace takes over below a balance point temperature, usually somewhere around minus 10°C to minus 15°C. That gets you the operating cost savings without giving up the reliability of gas on the coldest nights. For homes already on electric heat or propane with high fuel costs, a full heat pump replacement often pencils out faster. I give every homeowner a straight comparison before we decide anything.

A standard ducted heat pump installation in Durham Region typically runs between $4,500 and $8,500 installed, covering equipment and labour. Cold-climate variable-speed units sit at the upper end of that range because the equipment costs more, but they also deliver better efficiency and lower operating costs over time. A ductless mini-split installation for a single zone usually runs $2,500 to $4,500, depending on equipment capacity and the complexity of the line set routing. What moves the number around is mainly equipment size, efficiency tier, whether the existing air handler is compatible or needs replacement, and whether any electrical work is required before the heat pump can be safely connected. Homes in older parts of Bowmanville and Courtice sometimes need a panel upgrade, that’s a cost David’ll identify upfront so it’s never a surprise mid-job.

There are two main rebate streams worth knowing about. The Canada Greener Homes Grant offers up to $5,000 for a qualifying heat pump installation, subject to a pre- and post-retrofit home energy evaluation through Natural Resources Canada. The process takes some paperwork and time, but for an eligible installation it’s meaningful money. The second stream is Enbridge Gas’s rebate program for homeowners switching from gas heat to an electric heat pump, the amount varies by equipment efficiency rating and the program’s current funding status, so it’s worth confirming at quote time. Some municipalities in Durham Region have also offered additional incentives through local energy programs, though availability changes year to year. I’ll tell you at the time of your quote which rebates your specific equipment qualifies for and what documentation you’ll need to apply. The best way to get current numbers is to get a free quote from David and we’ll go through it together.
A straightforward replacement, swapping out an existing heat pump for a new unit where the ductwork and electrical are already set up correctly, typically takes four to six hours. A new installation in a home that’s converting from a gas furnace, where the air handler needs to be matched, refrigerant lines routed, and electrical connections made, usually takes a full day. A ductless mini-split installation for a single zone can be done in three to four hours if the line set routing is simple. Where jobs run longer is when something unexpected turns up: ductwork that needs modification, an electrical panel that needs attention, or a line set that has to go through a more complex path than anticipated. I’ll give you a realistic time estimate when we do the quote walk-through, I won’t tell you it’s a four-hour job if it’s going to take all day. Call (416) 508-4585 or book online and we’ll get it scheduled.
Start with the thermostat, confirm it’s set to Heat mode and that the setpoint is above the current room temperature. Then check both circuit breakers: the one for the indoor air handler and the one for the outdoor unit. Both need to be on, and a tripped outdoor breaker is a common reason the air handler runs but produces no heat. Next, look at the outdoor unit. If it’s completely encased in ice, the defrost cycle has failed and you’ll need a technician, don’t chip at it. If the unit looks clear but it’s still blowing cool air in heating mode, the reversing valve may be stuck. That’s the component that switches between heating and cooling, and when it sticks, the system runs in the wrong mode regardless of what the thermostat says. A stuck reversing valve needs a technician to diagnose properly. If you’ve checked all of those and the heat pump still isn’t performing, call (416) 508-4585, David serves all of Clarington and can usually get there the same day.
Yes, and for Clarington specifically it’s what I’d recommend for most new installations. A standard heat pump rated to minus 10°C or minus 15°C will spend a good portion of Clarington’s winter relying on electric backup heat during cold snaps, which is expensive and defeats a lot of the efficiency argument for going to a heat pump. Cold-climate units rated to minus 25°C maintain meaningful efficiency across the temperatures we actually see here in Durham Region from December through February. The equipment cost is higher, but the operating cost over a heating season is lower, and the payback period on the efficiency premium is typically three to five years depending on your electricity rate and how cold the winter runs. I carry and install several cold-climate models and can walk you through the efficiency specs and expected operating costs for each before you decide. Call me at (416) 508-4585 or book a free quote and we’ll figure out what makes sense for your home.
A heat pump cools your home in summer, that’s exactly how it works. The same refrigerant cycle that extracts heat from outdoor air and moves it inside during winter reverses in summer: the system pulls heat from inside your home and rejects it outdoors, operating identically to a central air conditioner. For Clarington homeowners who currently have a gas furnace and a separate central air conditioner, replacing both with a heat pump means one system handles both heating and cooling year-round. That’s one piece of equipment to maintain, one annual tune-up, and one phone number when something needs attention. The cooling efficiency of a modern heat pump, measured by its SEER2 rating, is comparable to or better than most standalone central air conditioners in the same price range. For homes considering a mini-split, each indoor head provides independent temperature control for its zone, so you’re cooling only the rooms that need it rather than the whole house.
“Our heat pump quit on a Friday night in January, David was at our Bowmanville house by Saturday morning and had it running before noon. The reversing valve had failed and he had the part on his truck.”
“I called David about a heat pump installation in our Courtice home and he told me straight away that our existing ductwork would need some attention before it’d work properly with a new unit. He came out, showed me exactly what the issue was, and we sorted it all in one visit. No surprises on the invoice, what he quoted was what we paid. I appreciated that he didn’t just install the equipment and leave me wondering why it wasn’t performing.”
“Got three quotes for a new heat pump in Newcastle. Cassar was competitive on price, but what sold me was that David actually explained what size unit my house needed and why, the other guys just threw numbers at me. He treated the place carefully, left nothing on the floor, and the whole job was done cleaner than it started.”
