What David Does in Pickering

Furnace Services for Pickering Homeowners

From a quick repair to a full high-efficiency installation, David handles it directly. No subcontractors, no call centres.

Furnace Installation in Pickering

New construction in Duffin Heights often calls for properly sized two-stage or variable-capacity furnaces to handle the larger floor plans, getting the load calculation right from the start matters. David sizes every installation to the actual home, not to whatever’s sitting on the truck. You get a firm, upfront price before any work begins.

Furnace Repair in Pickering

When the heat stops, David diagnoses the problem and tells you straight what it’ll cost to fix it. He stocks common parts on the truck, so most repairs in Pickering wrap up in a single visit. If a repair isn’t worth doing on a system that’s close to the end of its life, he’ll say so and explain why, not just add parts to the bill.

Furnace Replacement in Pickering

Bay Ridges and West Shore homes built in the 1950s and 60s are often running furnaces that are well past the 20-year mark. When replacement makes sense, David removes the old unit, handles disposal, and installs the new one with all required TSSA permits and inspections. There’s no pressure to upgrade to a model you don’t need.

Annual Tune-Up & Maintenance

A furnace tune-up with David covers the heat exchanger, burners, ignitor, blower motor, flue, and safety controls. He cleans what needs cleaning, tests what needs testing, and flags anything that’s about to become a problem before it does. Booking before the heating season starts means you’re not calling in an emergency at midnight in January.

High-Efficiency Upgrade

Moving from an 80% AFUE furnace to a 96% or higher unit reduces what you spend on gas every month. David calculates whether the venting on your existing setup can support a high-efficiency installation or whether it needs to be modified, and he explains the difference before you sign anything. Ontario’s Enbridge Gas rebate programs can offset a portion of the cost on qualifying equipment.

Emergency Furnace Service in Pickering

A furnace failure at 2 a.m. in a Pickering January isn’t something you want to wait until morning on, especially with kids or elderly family in the house. David takes emergency calls personally and gets to you as quickly as possible. You won’t reach a dispatch queue, you’ll reach David, and he’ll tell you honestly whether it’s a same-night fix or a next-morning job.

Why Cassar HVAC

Pickering’s Trusted Furnace Experts

I’ve been working in Pickering homes since 2011, and I’ve seen the same patterns repeat: older bungalows in Bay Ridges with undersized ducts that make a high-efficiency install more complicated than a big-box quote suggests, and newer Duffin Heights builds where the original furnace was speced at the minimum to cut construction costs. I know what I’m walking into before I open my toolkit, and I’ll tell you what I find without dressing it up.

Pickering Furnace Guide

Everything Pickering Homeowners Need to Know About Furnace Installation, Repair & Maintenance

How long does a furnace last in Ontario?

Most gas furnaces installed in Ontario run reliably for 15 to 20 years. Some push past 25 years with consistent maintenance, and some fail well before 15 if they’ve been neglected or were undersized from the start. The honest answer is that a well-maintained furnace from a reputable brand, installed correctly and serviced annually, will land somewhere in that 18 to 22 year range in most cases.

Ontario’s climate is hard on HVAC equipment. Furnaces run for five to six months of the year in Durham Region, sometimes longer, and the fluctuating temperatures in fall and spring mean the system cycles on and off constantly rather than running at steady state. That cycling puts more wear on the heat exchanger and the ignitor than a climate with a longer, steadier heating season would. Keeping the filter clean is the single biggest thing a homeowner can do to extend lifespan, a clogged filter forces the blower to work harder and drives heat exchanger temperatures up, which shortens its life significantly.

If your furnace is past 15 years and needs a repair that costs more than $600 to $800, it’s worth having a frank conversation about whether repair or replacement makes more economic sense. David will give you that conversation straight, without pushing you either direction.

Furnace costs in Pickering, what to expect

A furnace repair in Pickering typically runs between $150 and $900, depending on what’s failed. An ignitor replacement or a simple pressure switch swap sits at the lower end. A heat exchanger replacement or a variable-speed motor sits toward the higher end, and at that point the age of the unit matters a lot in the repair vs replace decision. A diagnostic visit to identify the problem has its own charge, which gets applied toward the repair if you proceed.

A new furnace installation in Pickering, including equipment, labour, and the required permits and inspections, runs roughly $3,500 to $6,500 for most homes. The spread comes down to efficiency rating, whether the venting needs to be modified (single-pipe vs two-pipe systems), whether the ductwork needs any adjustments for the new unit’s airflow specs, and the brand and model you choose. A Duffin Heights home with a larger square footage and a more complex duct layout will cost more to install correctly than a Bay Ridges bungalow with a straightforward one-pipe setup.

Every job gets a free, upfront quote from David before any work starts. The quote he gives you is the price on the invoice.

Pickering housing and furnace considerations

Pickering’s housing stock spans roughly six decades of construction, and that range creates genuinely different furnace challenges across the city. The Bay Ridges, West Shore, and Rougemount neighbourhoods contain a large concentration of post-war and 1960s-era homes, many of which still have their original duct systems. Those ducts were designed for lower-static, lower-efficiency equipment, and dropping a modern 96% AFUE variable-speed furnace into one of those homes without recalculating the duct sizing is a mistake that leads to noise complaints, poor heat distribution, and premature equipment wear. David checks duct sizing as part of every installation assessment in these neighbourhoods.

The Duffin Heights and Seaton communities represent the other end of the spectrum: new and relatively new builds that are often well-insulated but have longer duct runs to reach bedrooms at the far end of the home. Undersized furnaces in these homes run continuously without reaching setpoint on the coldest nights, which wastes gas and stresses the equipment. Getting the Manual J load calculation right matters in these homes just as much as it does in the older stock, for different reasons.

Homes near the Lake Ontario waterfront in Pickering also deal with higher humidity levels that can affect ductwork and filter maintenance cycles. David’s seen accelerated filter clogging in some of the older Bay Ridges homes during humid stretches, and he’ll flag that and recommend a filter schedule that actually works for the specific home rather than the generic “every three months” advice that gets printed on filter packaging.

Signs your furnace needs attention in Pickering

Short cycling, the furnace fires, runs for a minute or two, then shuts off before the home reaches temperature, points to a few specific causes. A clogged air filter is the most common trigger. A failing high-limit switch is the next most likely culprit. In older Pickering homes with narrow duct systems, an oversized furnace will short cycle structurally because it heats too fast and trips the limit before the air distributes properly. Each of those causes has a different fix, and they’re easy to tell apart once you’re looking at the unit.

Unusual sounds deserve attention. A banging on startup usually means delayed ignition, gas builds up in the combustion chamber before the ignitor fires, and the mini-explosion that follows is hard on the heat exchanger. A squealing sound during operation typically points to a blower motor bearing that’s starting to fail. Rattling can be as simple as a loose panel or as serious as a cracked heat exchanger, so it’s worth having it checked rather than ignored.

Durham Region homeowners sometimes notice that their gas bills climb significantly from one January to the next without an obvious explanation. If your consumption is up and the weather wasn’t materially colder, the furnace is worth inspecting, a dirty burner assembly, a partially clogged heat exchanger, or a failing economizer on a high-efficiency unit all reduce combustion efficiency without setting off any obvious alarm.

Getting the most from your furnace in Durham Region’s climate

Durham Region’s heating season runs from roughly late October through early April in a typical year, with the hardest stretch falling between December and February when overnight lows in Pickering regularly hit -15°C or colder. Your furnace does most of its work in a short window, which means a problem that started developing in September often shows up as an emergency in the first cold snap of December. An annual tune-up in September or early October catches those developing issues before they become failures.

A programmable or smart thermostat pays for itself quickly in this climate. Setting the overnight temperature back by even 2°C reduces your heating load meaningfully over a five-month season. David can advise on thermostat compatibility with your existing furnace during a service visit, not all older multi-stage systems work cleanly with every smart thermostat on the market, and a mismatch causes the furnace to behave oddly or lock out entirely.

Keeping intake and exhaust vents clear of snow and ice is specific to high-efficiency furnaces, which vent through plastic pipes near the foundation rather than through a chimney. Those pipes are low to the ground and can get blocked during heavy snowfall or an ice storm. A blocked vent triggers an automatic safety shutoff, and clearing the obstruction and restarting the furnace is something most homeowners can handle themselves, David covers this in the troubleshooting section below.

Furnace safety and efficiency for Ontario homeowners

Carbon monoxide is the most serious safety concern with any gas furnace. A cracked heat exchanger allows combustion gases, including CO, to mix with the air circulating through your home. CO is odourless and colourless, which means a working CO detector on each floor is non-negotiable. Ontario’s Fire Code requires CO detectors in homes with fuel-burning appliances, and the TSSA recommends the heat exchanger be inspected annually as part of a furnace tune-up. David inspects the heat exchanger visually and with a combustion analyzer during every maintenance visit.

The TSSA regulates all gas work in Ontario, including furnace installations, repairs to gas lines, and combustion equipment servicing. Any work on the gas side of your furnace requires a TSSA-licensed contractor. David holds TSSA Licence #000398183, which you can verify directly through the TSSA’s public licence lookup. Work done by an unlicensed contractor voids manufacturer warranties and can affect your home insurance coverage if something goes wrong.

On the efficiency side, Enbridge Gas runs rebate programs for Ontario homeowners who replace older, lower-efficiency furnaces with qualifying high-efficiency equipment. The rebate amounts change from year to year, but the programs have consistently offered $250 to $800 toward a qualifying installation. David can tell you whether the equipment he’s recommending qualifies during the quote process, and he’ll help you understand what documentation you’ll need to claim the rebate.

Before You Call

Furnace Not Working? Try These First

Checking the simple things before calling saves time for everyone, and one of these resolves the problem more often than you’d think.

🌡️

Check Your Thermostat

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.

Check the Breaker & Power Switch

Your furnace has a dedicated circuit breaker in your electrical panel and usually a wall switch nearby. Check both are on.

🌬️

Check Your Air Filter

A clogged filter restricts airflow and can trigger a safety shutoff. If you can’t see light through it, replace it before calling.

❄️

Check Outdoor Intake & Exhaust Vents

High-efficiency furnaces have plastic pipes exiting near the foundation. Snow or ice blocking these causes an automatic shutoff, clear them and restart.

🚪

Check the Furnace Door Panel

Many furnaces have a safety switch that cuts power if the access panel isn’t fully closed. Make sure it’s secured properly.

Furnace Still Not Working? Call Cassar.

If none of the above work, it needs a licensed technician. David serves all of Pickering and Durham Region and picks up the phone himself.

Common Questions

Furnace Questions from Pickering Homeowners

How often should I service my furnace in Ontario?

Once a year, before the heating season starts, is the right answer for most Ontario homeowners. In Pickering specifically, I’d recommend booking in September or October, before the first cold snap hits. Durham Region furnaces run hard from November through March, and a tune-up done after the first emergency call of the season is always more expensive and more stressful than one done in September when there’s no pressure. Annual servicing keeps the heat exchanger clean, the ignitor tested, and the combustion checked, all of which affect both safety and efficiency. If you have a high-efficiency furnace with a secondary heat exchanger, that component in particular benefits from yearly cleaning because condensate buildup restricts airflow gradually enough that you don’t notice it until the furnace starts short cycling. An annual service also catches deteriorating parts before they fail completely, which turns what would have been an emergency call into a routine part replacement at a scheduled visit.

Should I repair or replace my furnace?

The answer depends on three things: the age of the unit, the cost of the repair, and whether the furnace has other components that are close to failing. A furnace that’s under 12 years old and needs a repair under $500 is almost always worth fixing. A furnace that’s 18 years old and needs a heat exchanger replacement is almost always worth replacing, the repair cost rivals the value of the remaining useful life. The grey zone sits in between, and that’s where the honest conversation matters. I’ve had homeowners in Pickering come to me expecting to hear they need a full replacement, and I’ve told them a $280 ignitor swap will get another four years out of the unit. I’ve also had the opposite, someone expecting a repair quote who needed to hear that the heat exchanger had a crack and the unit wasn’t safe to run. I’ll give you the actual picture, not the answer that’s most profitable for me. If you’re on the fence, get a free quote from David and we’ll work through it together.

What AFUE rating should I choose for a Durham Region home?

For a home in Durham Region, a 96% AFUE or higher furnace is the right choice in most cases. Ontario’s natural gas prices and the length of the heating season mean the efficiency difference between an 80% and a 96% unit translates to real savings over a 15-year lifespan. The upfront cost of a high-efficiency unit is higher, but the delta often pays back within five to eight years in fuel savings, and Enbridge Gas rebates can shorten that payback period further. The one situation where an 80% AFUE unit might make sense is when the venting configuration in an older home makes the switch to a two-pipe condensing system prohibitively expensive, modifying a chimney-vented setup to accept a high-efficiency furnace sometimes requires significant work that changes the economics. I’ll tell you what the venting situation looks like in your home during the assessment and give you the numbers on both options so you can decide based on actual figures, not a sales pitch.

How long does furnace installation take in Pickering?

Most furnace installations in Pickering take four to six hours from start to finish. That covers removing the old unit, installing the new one, connecting the gas line, modifying or extending the venting as needed, wiring the thermostat, and running a full commissioning test to confirm the unit is operating correctly and safely before I leave. More complex jobs, a home where the ductwork needs adjustment, or where we’re converting from a chimney-vented 80% unit to a two-pipe 96% system, can take six to eight hours. I’ll tell you during the quote how long your specific job will take. I don’t leave a half-installed furnace and come back the next day. The job gets finished the day it starts so you have heat that night. If the installation requires a permit inspection from the TSSA, that gets scheduled separately and I coordinate it, you don’t have to chase anyone.

Does Cassar service all furnace brands?

Yes. I work on all major furnace brands, Lennox, Carrier, Trane, York, Goodman, Bryant, Rheem, Amana, Napoleon, and others. The diagnostic process is the same regardless of what’s on the nameplate, and I stock common replacement parts for the brands I see most often in Pickering homes. For less common brands or older units where parts need to be ordered, I’ll tell you the lead time upfront so you can decide whether to wait for the part or move to a replacement if the timeline is a problem. I won’t tell you a furnace needs replacing just because parts are harder to find, I’ll find the part if it exists and the repair makes sense for the age of the unit. If it genuinely isn’t available anymore, I’ll explain that and walk you through the replacement options without any pressure.

My furnace is blowing cold air, what’s wrong?

Cold air from a furnace almost always points to one of four things: the thermostat is set to “fan only” rather than “heat,” which runs the blower without firing the burners; the ignitor has failed and the furnace is running the fan but not actually producing heat; the high-limit switch has tripped due to overheating from a restricted airflow condition, usually a clogged filter; or on a high-efficiency unit, a blocked condensate drain has triggered a safety shutoff that cuts the burners but leaves the fan running. Start by checking your thermostat setting and replacing the filter. If those are both fine, the unit needs a diagnosis. A failed ignitor is a common repair that David stocks on the truck, and it’s typically a straightforward fix. A tripped high-limit switch needs to be reset and the underlying cause addressed, if it tripped because of a restricted filter, cleaning that fixes it. If it tripped because of a failing component, the underlying issue gets repaired at the same visit. Call David at (416) 508-4585 and he’ll walk through the basics with you on the phone before sending anyone out.

What should I do if I smell gas near my furnace?

Leave the house immediately and don’t touch any light switches or electrical devices on your way out. Once you’re outside, call Enbridge Gas at 1-866-763-5427, their emergency line operates 24 hours and they’ll dispatch a gas technician to make the situation safe before anyone else goes near the appliance. Don’t call anyone about repairs until Enbridge has cleared the scene and you have confirmation the immediate risk is contained. A faint smell of gas near the furnace during startup that clears within a few seconds can sometimes be normal as the burners light, but any persistent smell, any smell that’s getting stronger, or any smell that’s present when the furnace isn’t running is a genuine emergency. After Enbridge has cleared the situation, David can assess the furnace and determine what caused the leak. Gas work requires a TSSA-licensed contractor, and David holds TSSA Licence #000398183, so all the repair work stays properly certified.

Is financing available for furnace installation in Pickering?

Yes, financing options are available for furnace installations. A new furnace is a significant purchase, and spreading the cost over monthly payments makes it more manageable, especially when a failure has forced the decision faster than anyone planned. Financing is available through third-party lenders David works with, with terms typically ranging from 12 to 60 months depending on the amount and your credit situation. Interest rates and terms vary, and David can walk you through what’s available when you get your quote. For homeowners who qualify for the Enbridge Gas Home Efficiency Rebate program on high-efficiency equipment, the rebate gets applied to the project cost and can reduce the amount you’re financing. The cost of a furnace installation in Pickering varies from about $3,500 to $6,500 depending on the job, and the best way to know what your specific job will cost is to get a free quote from David, no pressure, no obligation.

“I called David about replacing our furnace in our Bay Ridges home. He came out, looked at the existing setup, and told me the old ductwork would need a few changes to work properly with a high-efficiency unit. He explained exactly why before quoting it. Most guys just throw a number at you and figure you’ll say yes, David actually showed me what he was looking at. The install went smooth and the house heats evenly now in a way it never did before.”

“The quote I got was the price I paid. No add-ons when he arrived, no surprises on the invoice. He put down drop cloths in the utility room and cleaned up before he left. I’ve dealt with contractors who leave a mess and bill you for the privilege, this was the opposite of that.”
