Clarington’s mix of newer Bowmanville subdivisions and older rural homes on Concession roads means AC equipment varies wildly, and David’s been sizing, repairing, and replacing it all since 2011. He covers all of Clarington, from Courtice to Newcastle, and picks up the phone same day.
From a first-time installation in a Bowmanville new build to an emergency repair on a 20-year-old unit in a Solina farmhouse, David handles the full range.
David sizes every installation to the actual square footage, ceiling heights, and insulation levels of the home, not a guess from the street. Clarington’s newer subdivisions in Bowmanville and Newcastle often have wider homes that need equipment matched carefully to the duct layout. You get an upfront quote before anything gets ordered.
David diagnoses the problem himself and tells you exactly what it is before quoting a repair. Common calls he gets across Clarington include refrigerant leaks, failed capacitors, and contactor issues on units that have been running hard through Durham Region summers. He carries most common parts and can often fix it the same day.
When a repair stops making financial sense, David will tell you that directly and walk you through replacement options that fit your budget and your home. He’ll never push a full replacement if a repair extends the life of your current unit by several good years. You decide with the full picture in front of you.
A spring tune-up before the heat hits covers coil cleaning, refrigerant level check, electrical connections, capacitor condition, and a full run-cycle test. Catching a weak capacitor in May costs a fraction of an emergency call in July. David books tune-ups across all of Clarington starting in April.
Upgrading to a 16 SEER2 or higher unit cuts your summer cooling costs noticeably compared to the 13 SEER units that were standard in many Clarington homes built in the late 1990s and 2000s. David walks you through the payback period so you can decide whether the upgrade makes sense for how long you plan to stay in the home.
When your AC quits during a July heat warning, David picks up the phone himself. He covers all of Clarington, including rural addresses on Concession roads east of Bowmanville where some contractors won’t travel. He’ll tell you honestly whether it’s a quick fix or something bigger, and he’ll give you the price before he starts.
I’ve been working in Clarington since 2011, and I’ve seen everything from poorly sized units in Courtice townhomes to ancient R-22 systems on hobby farms near Orono that the homeowner had no idea were a liability. My TSSA licence number is #000398183, you can verify it yourself. When I show up, I give you a straight answer, a real price, and I leave the place clean.
A central air conditioner in Ontario typically lasts between 15 and 20 years, though that range shifts significantly based on how the unit was sized, how often it’s maintained, and how hard it runs during peak summer months. A correctly sized unit that gets a tune-up every spring will reliably reach the high end of that range. An oversized or undersized unit, or one that’s been skipping annual maintenance, often starts showing serious problems around year 12.
Ontario’s climate shortens equipment life in ways that mild climates don’t. The freeze-thaw cycle causes refrigerant line vibration over time, and humid Durham Region summers push condenser coils hard through July and August. Salt-laden air near Lake Ontario’s shoreline, which affects parts of Clarington’s south end near Lake Vista and the waterfront, accelerates coil corrosion more than homeowners expect.
The single biggest thing that extends AC life is a clean air filter changed every one to three months during cooling season, and a professional coil cleaning each spring. A dirty evaporator coil makes the compressor work significantly harder on every cycle. That added strain accumulates fast over 15 summers.
A new central air conditioner installation in Clarington typically runs between $3,500 and $6,500 installed, depending on the unit’s efficiency rating, the size required for the home, and whether the existing refrigerant lines and electrical connections are in good shape. A straightforward replacement on a home with existing infrastructure lands closer to $3,500 to $4,500. A first-time installation where new linesets and electrical work are required can reach $5,500 to $6,500.
Repairs vary more widely. A capacitor replacement, one of the most common AC repairs David handles, runs $150 to $300 including the service call. A refrigerant recharge on a unit with a confirmed slow leak costs $300 to $600 depending on the amount needed and whether the leak source requires additional repair. Compressor replacement on an older unit often crosses $1,200 to $1,800, at which point replacement becomes worth the conversation.

Clarington has one of the more varied housing stocks in Durham Region. The municipality spans from dense residential subdivisions in Courtice, many built in the 1980s and 1990s, through Bowmanville’s established neighbourhoods and newer developments, all the way to rural properties on Concession roads east of Newcastle and north toward Orono and Kirby. That range means David sees equipment and duct configurations across the full spectrum on any given week.
Courtice homes built in the late 1980s frequently have ductwork sized for lower-capacity equipment and sometimes original air handlers that weren’t designed for the higher static pressures of modern high-efficiency units. Swapping in a new AC on that infrastructure without checking the duct sizing is a mistake that leads to noise issues, comfort complaints, and shortened compressor life. David checks the existing system before recommending equipment.
Newer Bowmanville and Newcastle subdivisions, particularly the growth areas along Green Road and Longworth Avenue, tend to have more modern ductwork, but these homes are also larger, often running 2,200 to 3,000 square feet or more. Undersizing the AC in a home that size means the unit runs continuously on hot days and never achieves the dehumidification the home needs. Rural properties on acreage often have older standalone systems, sometimes still running R-22 refrigerant, which has been phased out and requires full replacement when the system fails.
The most reliable early warning sign is an AC that runs constantly but can’t hold the set temperature on a day that’s only 28°C. In Clarington’s July heat, a properly sized and functioning unit should cycle on and off rather than run non-stop. Continuous operation without achieving the target temperature usually means a low refrigerant charge, a dirty coil, or a compressor that’s losing capacity.
Unusual sounds are another clear flag. A grinding noise from the outdoor unit typically points to a failing fan motor bearing. A clicking sound at startup that doesn’t resolve into normal operation often signals a failing capacitor, one of the most common repairs David handles across Durham Region in summer. A high-pitched squealing from the air handler usually means a worn blower motor belt on older units, or debris in the fan assembly on newer ones.
Ice forming on the refrigerant lines or on the outdoor unit is a sign something needs attention right away. It’s counterintuitive, but a frozen coil means the system has stopped cooling effectively. The cause is usually a blocked filter reducing airflow, or low refrigerant. Running the unit in that state risks compressor damage. Turn it off, switch the fan to ON (not AUTO) to thaw the coil, change the filter, and call David if it recurs.
Durham Region’s summer pattern runs from late June through mid-September with humidity levels that regularly push the humidex above 38°C during peak weeks. An AC in this climate isn’t just cooling air, it’s removing moisture, and that dehumidification function is as important as the temperature drop for actual comfort. A system that’s oversized will cool the air quickly but short-cycle before it removes enough humidity, leaving the home feeling clammy at the set temperature.
Set your thermostat to around 24°C and use a ceiling fan to extend comfort rather than dropping the AC setpoint further. Every degree lower on the thermostat adds roughly 5 to 8 percent to your cooling energy use. Keep blinds closed on south and west-facing windows during peak afternoon hours, that solar gain is the single largest heat source in most Clarington homes during summer afternoons.
Program your thermostat to raise the setpoint by 2 to 3 degrees during work hours and return to your comfort temperature an hour before you’re home. The AC recovers that differential faster than most homeowners expect, and the reduced runtime over 8 to 10 hours adds up to real savings across a full cooling season.
Central air conditioners don’t produce carbon monoxide, but the furnace or air handler they share equipment with does, and the cooling season is when many homeowners neglect annual furnace inspections. If your home has a gas furnace with a cracked heat exchanger, it’s a CO risk regardless of whether you’re in heating or cooling mode. David checks for obvious signs of furnace condition when he’s on site for AC work and will flag anything that warrants follow-up.
Ontario’s Enbridge Home Efficiency Rebate Plus program offers rebates for ENERGY STAR certified central air conditioners, including higher-tier SEER2 equipment. The rebate amounts change periodically but have historically ranged from $250 to $650 depending on the efficiency tier. David can confirm current rebate eligibility for the equipment he recommends and factor that into the total cost picture.
All refrigerant handling in Ontario requires a licensed technician. This is a TSSA-regulated activity, and any contractor who offers to “top up” your refrigerant without a proper leak diagnosis or without verifiable credentials is operating outside provincial regulations. David’s TSSA Licence #000398183 covers this work, and he’ll never simply recharge a leaking system without addressing the source of the leak.
Checking the simple things before calling saves time for everyone, run through these before you pick up the phone.
Make sure it’s set to Cool and the temperature is set below current room temperature. Check the batteries too, a weak battery causes erratic thermostat behaviour.
Your AC has a breaker in the main panel and an exterior disconnect box next to the outdoor unit. Check both are on.
A clogged filter blocks airflow and causes the evaporator coil to ice up, completely stopping cooling. Replace the filter and let the unit thaw for an hour before restarting.
The condenser unit outside needs clear airflow. Remove any debris, overgrowth, or objects within 60cm of the unit. Don’t hose it down while running.
Closed vents create pressure imbalances that reduce cooling and can damage the system. Make sure every supply vent in the home is open.
If none of the above resolved it, it needs a licensed technician. David covers all of Clarington and Durham Region and picks up the phone himself.
Once a year, every spring before you need it, is the right answer for most Ontario homes. A tune-up in April or May catches the things that fail during the first hot week of summer, a weak capacitor, low refrigerant, a dirty coil, when fixing them is a fraction of the cost of an emergency call in July. In Clarington, where summer heat waves can run several weeks straight, skipping a year tends to catch up with homeowners at the worst possible time. If your system is older than 12 years, an annual check also gives you advance warning that replacement is approaching, so you’re not making that decision under pressure at 11pm on a Thursday when the house is 30 degrees. David books tune-ups across Clarington starting in April each year, and they go fast, it’s worth scheduling before the rush.
The most common causes are a dirty air filter restricting airflow, low refrigerant from a slow leak, a failing capacitor preventing the compressor from starting properly, or a dirty condenser coil that can’t reject heat efficiently. Start by replacing the air filter and checking the outdoor unit for debris. If the system is running but the air coming from the vents feels warm, that points to low refrigerant or a compressor issue. If the outdoor unit isn’t running at all but the air handler is, a failed capacitor or tripped breaker is the likely cause. In Clarington’s older Courtice-area homes, David also regularly finds ductwork leaks that bleed conditioned air into unconditioned crawlspaces and attics, the AC runs, the house stays warm, and the issue isn’t the unit at all. If the simple checks don’t resolve it, call David and he’ll diagnose it before quoting anything.
A standard central AC replacement, swapping out an existing outdoor unit and coil on a home with serviceable refrigerant lines and an existing electrical disconnect, takes four to six hours in most cases. David works alone, which means the person who quoted the job is the person doing the work, and the timeline he gives you reflects how he actually works. A first-time installation where new refrigerant lines, an electrical disconnect, and a new air handler coil are all required adds two to three hours. If the electrical panel needs a dedicated circuit added, that’s a separate electrician visit that David can help coordinate. Permit requirements in the Municipality of Clarington apply to new installations and David handles that documentation as part of the job. You won’t be left to figure that out on your own.
The honest answer depends on three things: how old the unit is, what the repair costs, and whether the refrigerant type is still available. A general rule David applies is the “5,000 rule”, multiply the unit’s age by the repair cost. If the result exceeds $5,000, replacement is usually the better financial decision. A 14-year-old unit facing a $400 capacitor repair gets a score of 5,600, borderline. A 16-year-old unit needing a $900 refrigerant fix scores 14,400, replace. But these are starting points, not conclusions. If the rest of the unit is in good shape and the compressor has many years left, a repair still makes sense even when the math says borderline. If the unit runs on R-22 refrigerant, which has been phased out, factor in that any future refrigerant work will be extremely expensive.

For a Durham Region home, a SEER2 rating of 15 to 17 hits the practical sweet spot between upfront cost and long-term energy savings. As of 2023, the minimum standard in Canada moved to SEER2 (a slightly more demanding test standard than the old SEER), and entry-level units now start at 13.4 SEER2. The jump from minimum-efficiency equipment to mid-efficiency (around 16 SEER2) typically reduces cooling electricity consumption by 15 to 20 percent, meaningful savings across a Durham Region summer that can run three months of consistent AC use. Going to 18 or 20 SEER2 adds cost that takes longer to recover unless you’re in the home long-term or your hydro rates increase significantly. David sizes the equipment first and then recommends the efficiency tier that makes sense financially for your situation. He’ll tell you the payback period before you decide.
When the system runs but produces warm or room-temperature air from the vents, the two most likely causes are a low refrigerant charge and a failed compressor. Low refrigerant from a slow leak is more common and more fixable, David confirms the charge level with gauges, locates the leak source, repairs it, and recharges the system. A failed compressor is the more expensive diagnosis; on a unit older than 12 years, replacement of the whole system often makes more sense than a compressor swap. A third possibility is a frozen evaporator coil, ice blocks airflow and the air coming through feels barely cool. Shut the system off, run the fan only for an hour to thaw it, replace the air filter, and restart. If it freezes again, the airflow restriction is internal and needs a technician. David covers all of Clarington and can usually get to you same day for a diagnosis.
Yes. David works on all major residential central air conditioner brands, including Carrier, Lennox, Trane, York, Goodman, Daikin, Napoleon, Keeprite, and Bryant, among others. The diagnostic process for refrigerant systems is largely consistent across brands, refrigerant pressures, electrical components, and coil performance follow the same principles regardless of the nameplate on the unit. Brand-specific differences show up mostly in control board configurations and proprietary error codes, and David’s experience since 2011 covers those across the most common equipment in Clarington and Durham Region homes. If you’ve got an older unit from a brand that’s been discontinued or absorbed into a larger manufacturer, David can still diagnose and repair it, though parts availability on very old equipment sometimes factors into the repair vs replace decision.
Yes, financing options are available for AC installation across Durham Region, including Clarington. A new central AC installation is a significant expense, typically $3,500 to $6,500 depending on equipment and scope, and spreading that cost over monthly payments makes it manageable for most homeowners. David works with financing partners that offer approved credit options with competitive terms, so you’re not choosing between a functioning AC and your monthly budget. The financing conversation happens after you have your quote, so you know exactly what you’re financing before you commit to anything. It’s worth asking about current promotional rates when you call, as low-interest periods apply seasonally.

“Our AC died on the hottest day of the summer, David had it diagnosed and a new capacitor in within two hours of calling. House was back to normal before dinner.”
“I called three HVAC companies about replacing my AC and two of them quoted me for a unit without even looking at the ductwork. David came out, checked the whole system, and told me my ducts in the Courtice house were undersized for what the other guys were recommending. He sized it properly, installed it cleanly, and the difference in how evenly the house cools is noticeable. He’s the only one who actually looked at the full picture.”
“Quoted me $4,200 for the installation. Invoice came in at $4,200. He put down floor covers, took the old unit away, and didn’t leave so much as a smudge on the wall. For a big job like a new AC in a Bowmanville home, that kind of tidy work matters.”
