Furnace Installation & Repair

Furnace installation, furnace repair, and emergency no-heat response across Toronto and the GTA. Our TSSA-certified crew installs high-efficiency condensing gas furnaces from Lennox, Carrier, and Trane sized to your home using Manual J heat load calculation, and we repair every major furnace fault: hot surface igniter failures, flame sensor faults, draft inducer motor issues, pressure switch problems, and secondary heat exchanger diagnostics. Every high-efficiency furnace we install is ENERGY STAR rated with ECM variable-speed blower motor, single-stage or two-stage burner options depending on home size, and PVC condensing venting to code. Ontario Home Renovation Savings (HRS) Program pays $250-$1,000 on qualifying furnace installations, and rebate paperwork is filed on your behalf. TSSA safety inspection included on every install. Furnace repairs typically run $250-$500 on a $150 diagnostic; new furnace installation runs $3,500 to $7,500 depending on AFUE tier, single-stage vs two-stage vs modulating configuration, ductwork correction, and venting requirements. Same-day weekday emergency capacity and 24/7 dispatch during winter cold snaps.

Best HVAC Toronto technician checking refrigerant gauges at an outdoor AC condenser beside a Toronto home

Central air conditioning installation, AC repair, and 24/7 emergency dispatch during Toronto summer heat waves. Our TSSA-certified crew installs SEER2 and EER2-rated condensing units from Lennox and Carrier with a scroll compressor, matched evaporator coil, and thermostatic expansion valve (TXV), sized with a Manual J heat load calculation for your home. We handle the R-410A to R-454B and R-32 refrigerant transition, and we hold current EPA 608 and A2L refrigerant certification for refrigerant handling and CFM airflow balance commissioning. AC repairs cover capacitor and contactor faults, refrigerant leaks with subcooling and superheat diagnostics, and frozen coil and airflow issues, starting with a $150 diagnostic that applies to the repair. Most repairs run $250-$600; central AC installation runs $4,000-$8,000 installed depending on tonnage, SEER2 rating, and whether ductwork correction or line set replacement is needed. Typical emergency response is 2 hours across the GTA.

Best HVAC Toronto technician commissioning a cold-climate heat pump outdoor unit beside a Toronto home in winter Rebates up to $6,500

Cold-climate air-source heat pump (ccASHP) installation across Toronto and the GTA, covering both single-stage residential retrofits and dual-fuel hybrid systems paired with existing gas furnaces. Every heat pump we install is NEEP cold-climate listed and NRCan qualified for the current Ontario Home Renovation Savings (HRS) rebate up to $7,500, Canada Greener Homes Loan up to $40,000 interest-free, and the Toronto BetterHomesTO HELP program stacked where eligible. Our TSSA-certified crew sizes every heat pump using Manual J heat load calculation and Manual S equipment selection to match HSPF2 and SEER2 ratings to your home, with defrost cycle commissioning, reversing valve testing, auxiliary heat strip integration, and inverter compressor tuning at start-up. Total system cost typically lands between $8,000 and $15,000 installed before rebates, with net cost after HRS and Greener Homes stacking often between $2,000 and $7,000 out of pocket.

Best HVAC Toronto technician servicing a wall-mounted condensing combi boiler in a Toronto basement utility room

Boiler installation, boiler repair, and hydronic radiant in-floor heating system service across Toronto and the GTA. Our TSSA-certified crew installs condensing combi-boilers, system boilers, and cast iron sectional boiler retrofits from Navien, Bosch, and Viessmann, with proper hydronic loop commissioning covering circulator pump sizing, expansion tank pressure, low-water cutoff (LWCO) safety installation, and outdoor reset control programming to modulate boiler output against outdoor temperature.

Hydronic zone additions and radiator retrofits are quoted per project. Boiler repair starts with a $150 diagnostic, and most service calls run $250-$500.

Best HVAC Toronto gas technician installing a black iron gas line with a shut-off valve in a Toronto basement

TSSA-permitted natural gas line installation across Toronto and the GTA for furnaces, water heaters, ranges, dryers, gas fireplaces, standby generators, outdoor BBQs, fire tables, and outdoor kitchen manifolds. Our G1 and G2 gas technicians install Schedule 40 black iron pipe for main runs and CSST (corrugated stainless steel tubing) for runs through finished space, with shut-off ball valve at every appliance, sediment trap (drip leg) at each terminal, and exterior quick-disconnect box for outdoor BBQ hookups. Every installation includes BTU load sizing against total appliance demand, verification that the existing meter and main supply can carry the added load, water column pressure (W.C.) reading at each appliance, and a formal TSSA pressure test tag filed on completion to CSA B149.1. Permits pulled and inspection sign-off filed on your behalf. Short indoor runs to a stove or dryer typically land $400-$800 installed; BBQ hookups run $400-$1,200 depending on outdoor run length; generator connections and outdoor kitchen manifolds run $800-$3,500 based on load and complexity.

Best HVAC Toronto technicians servicing a commercial rooftop unit on a flat roof in Toronto

Commercial HVAC installation, commercial heating and air conditioning service, and Planned Maintenance Agreements (PMAs) across Toronto and the GTA for restaurants, retail, offices, warehouses, and light industrial facilities. Our TSSA-certified crew services Rooftop Units (RTUs), packaged gas/electric units, make-up air units (MUA) for restaurant kitchen exhaust replacement, variable air volume (VAV) box commissioning, economizer with enthalpy sensor tuning, and 3-phase power HVAC equipment. Every install and service follows ASHRAE 62.1 for ventilation (typically 15-20 CFM outdoor air per occupant) and ASHRAE 90.1 for building energy performance code. Restaurant HVAC covers Type I hood exhaust rate sizing per NFPA 96 and matching MUA capacity for negative-pressure avoidance. Retail HVAC covers zone control commissioning across leased areas, thermostat migration to smart controls, and demolition-and-rebuild airflow rebalancing. Standard PMAs cover quarterly filter changes, biannual coil cleaning, annual combustion analysis and belt inspection, and priority dispatch during heat waves and cold snaps. A typical smaller commercial PMA (3-5 RTUs, 20,000-40,000 sq ft) runs $2,000-$4,500 annually at 2026 rates, with 10-15% repair discounts.

2-Hour Dispatch via the 401, Kingston Road & Sheppard

Scarborough covers a wide stretch of east Toronto, so routing matters. We dispatch along Highway 401, Kingston Road, and Lawrence Avenue East, which lets us hold a two-hour emergency target from Birch Cliff and Cliffside all the way out to Rouge, Malvern, and Highland Creek.

The 401 through Scarborough is one of the slowest stretches in the GTA between 3 PM and 7 PM. For late-day calls in Agincourt, L'Amoreaux, and Malvern we route on Sheppard or Finch, Wexford and Bendale calls near Scarborough Town Centre come off Lawrence or McCowan, and for the Bluffs, Guildwood, and West Hill we come along Kingston Road. Morning appointments consistently get the tightest arrival windows.

No-heat calls, gas leaks, and Enbridge red tags are covered around the clock, and emergency air conditioning repair runs 24/7 during summer heat waves. Winter no-heat calls in Scarborough spike during the first hard freeze each year, so if your furnace is short-cycling in November, book the diagnostic then rather than waiting for it to fail in January.

Bungalows, Finished Basements & Aging Furnaces

Scarborough has a lot of large detached homes, post-war bungalows, and side-splits in Wexford, Bendale, and Cliffside, many of them with finished basements added over the years. That combination creates the classic Scarborough complaint: a cold basement and an overheated second floor, usually caused by ductwork that was never extended or rebalanced after the renovation. Newer semi-detached homes and townhouses in Malvern, Rouge, and Woburn have tighter mechanical rooms, so equipment sizing and venting routes need more planning there.

Equipment-wise we see plenty of 15 to 25 year old mid-efficiency furnaces, first-generation high-efficiency units approaching the end of their life, and central air conditioners still running on older refrigerant. Heat exchanger inspections and combustion testing are a routine part of every maintenance visit, and we check the hot water tank and its venting at the same time because the two often share a chimney.

Rebate uptake is high in Scarborough. Homeowners replacing an old furnace often ask about pairing it with a cold-climate heat pump, and the payback on a dual-fuel setup is realistic in this housing stock because most homes already have good duct capacity. Swapping an old dial thermostat for a programmable smart thermostat during the same visit is one of the simplest ways to cut heating bills in a drafty bungalow.

Reviews

What Scarborough customers say

4.9 out of 5 from 150+ customer reviews

Our AC died during the July heat wave. They came out same day, diagnosed a refrigerant issue, and had us cool again fast. Honest about repair versus replace, and they didn't push us into a new system.

SSandra L.Agincourt

The basement was always freezing. Instead of selling us a bigger furnace they fixed the return air and added a run. Costs a lot less than what the other quote suggested.

EErrol M.Guildwood

They handled the heat pump rebate paperwork start to finish. I would have given up on it myself. Install was tidy and on schedule.

Local FAQ

Scarborough HVAC Questions, Answered

How quickly can you respond to a no-heat or no-AC call in Scarborough?

Two hours is our target across Scarborough, including Agincourt, Guildwood, Malvern, Cliffside, Rouge, and West Hill. Gas emergencies, red tags, no-heat, and no-AC calls are handled 24/7. Because the 401 slows badly through Scarborough in the late afternoon, we route on Sheppard or Kingston Road for peak-hour calls and give you a firm arrival time when you book.

Why is my Scarborough basement cold when the upstairs is too warm?

It is almost always a duct problem rather than a furnace problem. Many Scarborough bungalows had basements finished years after the original ductwork was installed, so there is not enough supply or return air downstairs. We measure static pressure and airflow first, then fix the distribution, which is normally far cheaper than replacing equipment.

Do you handle Enbridge red tags in Scarborough?

Yes. Our TSSA G1/G2 technicians inspect the tagged appliance, complete the repair, and sign the clearance so Enbridge can restore gas service. Red tag inspections start from $350, and most Scarborough red tags are cleared with gas restored within 24 hours of our first visit.

What rebates can I get for a Scarborough furnace or heat pump upgrade?

As of 2026, cold-climate heat pump installs can qualify for up to $6,500 combined through Ontario's Home Renovation Savings program and federal Canada Greener Homes support, and ENERGY STAR-rated high-efficiency furnaces are also rebate-eligible. We check eligibility on site and complete the application paperwork for you.

How much does AC repair or installation cost in Scarborough?

AC repair starts with a diagnostic from $150, and most repairs are quoted in writing on the spot. Central AC installation typically runs $4,000 to $8,000 at 2026 pricing, depending on tonnage and SEER2 rating. Where existing ductwork is undersized, we tell you before quoting, because a larger system on restricted ducts creates noise and short-cycling instead of comfort.

How much does furnace replacement cost in Scarborough?

Most Scarborough furnace replacements land between $3,500 and $7,500 installed, depending on the efficiency tier, blower type, and whether venting or ductwork needs rework. Older bungalows with shared chimney venting sometimes need a liner, which we quote separately and in writing before we start.

What is the most common HVAC problem in Scarborough homes?

Restricted airflow is the one we see most: clogged filters, closed-off returns, and ductwork that was never rebalanced after a basement was finished. In winter it shows up as short-cycling furnaces and tripped limit switches, and in summer as frozen AC coils. Failed igniters, dirty flame sensors, and incorrectly set thermostats round out the most common no-heat calls.

Which furnace and heat pump brands are best for Canadian winters?

Brand matters less than the right model and a proper load calculation. For heat pumps, choose a unit on the NEEP cold-climate list that is also NRCan-qualified; for furnaces, a 95 percent or higher AFUE condensing model. We are an authorized dealer for Lennox, Carrier, Trane, Bosch, Napoleon, and York, and we size every installation to your home.

Do you service Scarborough's older bungalows with shared chimney venting?

Yes, and it is one of the more common jobs here. When a high-efficiency furnace replaces a chimney-vented one, the hot water tank is often left venting into an oversized chimney. We assess the full venting picture and re-plan or line it so the installation is safe and code-compliant.

Is there an HVAC company near me in Scarborough?

Yes. Our technicians cover every Scarborough neighbourhood, including Agincourt, Guildwood, Malvern, Cliffside, Rouge, Wexford, Woburn, Bendale, West Hill, Highland Creek, Birch Cliff, L'Amoreaux, and the Bluffs, with a two-hour emergency target. We also cover neighbouring North York and Pickering, so boundary addresses are never a problem.

Are your technicians in Scarborough licensed and insured?

Yes. Every Best HVAC Toronto technician holds a TSSA G1 or G2 gas licence, is background-checked, and works under WSIB coverage and a $2 million general liability policy. The company is an HRAI member, and installations carry a 2-year labour warranty plus 5 to 10 years of manufacturer coverage.
