Best HVAC Toronto G1/G2 gas technician testing a red-tagged furnace with a combustion analyzer in a Toronto basement Our specialty

24/7 Enbridge red tag removal across Toronto and the GTA, with a 2-hour typical emergency response and a TSSA G1/G2 clearance signature on the first visit. We clear Type A tags (immediate natural gas shut-off for a leak, cracked furnace heat exchanger, or carbon monoxide spillage) and Type B tags (30 to 45-day compliance window for venting, piping, or gas pressure deficiencies) to Ontario Regulation 215/01 and CSA B149.1, then coordinate the relight with Enbridge Gas. Inspections start at $350 (2026 pricing).

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. Repairs cover pump failures, diverter valve faults on combi units, pressure loss diagnostics, kettling from limescale buildup on the primary heat exchanger, and inconsistent radiator temperature balancing across the loop. Every combi boiler installation includes DHW flow rate sizing against household hot water demand and PVC or polypropylene venting to CSA B149.1. As of 2026, boiler installation runs $5,000-$15,000 depending on type and capacity: combi boilers typically $6,000-$11,000 installed, condensing system boilers with indirect tanks and multiple zones $7,000-$13,000, and larger multi-zone or commercial boilers up to $15,000. 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 Along the QEW, 403 & 401

Mississauga is covered off the QEW, Highway 403, Highway 401, and Highway 407, which gives us solid access from Port Credit through to Meadowvale. Two hours is our emergency target city-wide, and our Peel Region crews also cross into neighbouring Etobicoke, Brampton, and Oakville every day.

The QEW through Mississauga is slow eastbound in the morning and westbound in the late afternoon, so for Port Credit, Lakeview, and Cooksville we often come along Lakeshore Road or Dundas Street instead. Streetsville, Erin Mills, Churchill Meadows, and Meadowvale are usually quickest off the 403 or Erin Mills Parkway, and condo towers in City Centre around Square One are a short run off the 403.

Gas emergencies, Enbridge red tags, and heating failures are covered 24/7 across the city, from the streets near Port Credit GO to the homes around Clarkson and Lorne Park. Mississauga is one of our higher-volume red tag areas, largely because of the mix of older Port Credit and Cooksville housing with original venting.

Lakeshore Homes, 1980s Subdivisions & Their Systems

Mississauga spans about seventy years of construction. Port Credit, Lakeview, Cooksville, and Streetsville hold older detached homes and bungalows with aging gas appliances and, frequently, chimney venting that has not kept pace with equipment changes. Erin Mills, Meadowvale, and Churchill Meadows are mostly 1980s to 2000s subdivisions of detached homes, semis, and townhouses with builder-grade furnaces and central air now due for replacement.

In the older core we run a lot of combustion testing and venting corrections. When a homeowner replaced a furnace years ago and left a water heater on an oversized chimney, that is a common source of poor draft and eventually a red tag. Older homes with hot-water radiators and no ductwork are good candidates for ductless mini-split systems or a cold-climate heat pump, and as of 2026 eligible heat pump installs can qualify for rebates of up to $6,500.

For the newer subdivisions, annual furnace and AC maintenance is what keeps 20- and 30-year-old builder equipment running, and our tune-ups flag cracked heat exchangers and failing blower motors before they turn into a mid-winter no-heat call. Every replacement is sized to a load calculation and installed to Ontario Building Code and TSSA gas code, with permits handled for you.

Backyard gas work is a strong theme here. Newer subdivisions and renovated older homes in Lorne Park and Clarkson both generate steady demand for BBQ hookups, outdoor kitchens, fire tables, and gas fireplaces, all of which we install with proper BTU sizing, permits, and pressure testing.

What Mississauga customers say

4.9 out of 5 from 150+ customer reviews

Enbridge tagged the water heater and shut the gas off. They came out the same evening, sorted the venting, and got the clearance signed the next morning.

HHassan A.Cooksville

Gas line for the BBQ and a fire table. Permit handled, pressure test done, backyard put back exactly as it was. No complaints at all.

LLaura M.Streetsville

Original 1994 furnace finally quit. Clear quote, no upselling, and they were realistic about which efficiency tier actually made sense for our house.

Local FAQ

Mississauga HVAC Questions, Answered by Our Technicians

How quickly can you reach an emergency in Mississauga?

Two hours is our target city-wide, from Port Credit and Lakeview through Cooksville, Erin Mills, Streetsville, and Meadowvale, with 24/7 coverage for gas emergencies and red tags. QEW congestion can affect peak-hour arrivals, so we route along Lakeshore Road or Dundas Street when it helps.

Do you clear Enbridge red tags in Mississauga?

Yes, and Mississauga is one of our busiest red tag areas. Our TSSA G1/G2 technicians inspect the tagged appliance, diagnose the fault, complete the repair, and sign the clearance so Enbridge can restore gas. Most tags are resolved within 24 hours of our first visit.

Why do older Mississauga homes get red-tagged for venting?

It usually traces back to a partial upgrade. When a high-efficiency furnace was installed years ago, it stopped venting into the chimney, leaving the water heater alone on a flue that is now far too large to draft properly. That causes spillage and condensation, which an inspector will tag. The fix is re-lining or re-venting, which we quote up front.

How much does a BBQ gas hookup cost in Mississauga?

Typical BBQ hookups run $400 to $1,200 at 2026 pricing, depending on the run length, routing, and whether the line goes through a finished basement. Larger outdoor kitchens, fire tables, and pool heaters are quoted by total BTU load and distance. Permits and a TSSA pressure test are always included.

What does furnace installation cost in Mississauga?

Most installations land between $3,500 and $7,500 in 2026 depending on efficiency tier and blower type, with Lennox, Carrier, Trane, Bosch, and York units available. Homes needing venting rework or a chimney liner will see that quoted as a separate, clearly itemised line rather than added as a surprise mid-job.

Is it worth replacing a 30-year-old furnace?

In most cases, yes. A furnace from the 1990s typically runs at 60 to 80 percent AFUE, while a new high-efficiency unit reaches 95 percent or more, and parts for older models are getting hard to source. We still diagnose first, and if a repair makes sense we will say so; replacements run $3,500 to $7,500 in 2026.

What is the $5,000 rule for air conditioners?

Multiply the age of the unit by the repair cost. If the result is over $5,000, replacement is usually the better value; a 15-year-old AC with a $400 repair scores $6,000. New central air runs $4,000 to $8,000 at 2026 pricing depending on tonnage and SEER, and we give you both numbers in writing before you decide.

How much does an HVAC repair visit cost in Mississauga?

Diagnostics start from $150, and most furnace or AC repair calls run $250 to $500 including common parts. You get a written price before any work starts, with no hidden fees, and same-day service is available for most repairs Monday through Saturday.

Do you service condos in Port Credit and City Centre?

Yes. We work on in-suite fan coils, ductless systems, heat pumps, and ventilation equipment in condo buildings, from Port Credit and Lakeview to the towers around Square One. Most buildings require a certificate of insurance and pre-booked elevator access, which we arrange with the property manager before the visit.

Is there an HVAC technician near me in Mississauga?

Yes. Our Peel Region crews cover every Mississauga neighbourhood, including Port Credit, Streetsville, Erin Mills, Meadowvale, Cooksville, Clarkson, Lorne Park, Malton, Churchill Meadows, and City Centre, with a two-hour emergency target. We also cover neighbouring Etobicoke, Brampton, and Oakville.

Are your Mississauga technicians 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.
