Vaughan HVAC Contractor for Furnaces, Heat Pumps & AC

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, 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.

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.

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.

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.

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.

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.
