Heating and Cooling Services for Richmond Hill Homes

Best HVAC Toronto has served Richmond Hill homeowners since 2005 with TSSA-certified furnace, air conditioning, heat pump, and gas fireplace service. We keep the heating and cooling systems in the larger custom homes of Oak Ridges, Bayview Hill, Mill Pond, Jefferson, and Observatory running safely, from red tag and carbon monoxide inspections to outdoor kitchen hookups.

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 via Highway 404, 407 & Yonge Street

Richmond Hill is served off Highway 404, Highway 407, Yonge Street, and Bayview Avenue. Two hours is our emergency target across the city, with Bayview Hill, Observatory, and the Richvale streets near Hillcrest Mall typically at the quicker end, and Oak Ridges and the homes around Lake Wilcox adding a little drive time on the north side.

Highway 404 runs heavy northbound after 4 PM, so late-day calls in Jefferson, Westbrook, and Oak Ridges are routed on Bayview or Leslie. Yonge Street through Mill Pond is slow through most of the day and we plan around it, while Rouge Woods and Devonsleigh on the east side are a short run up Leslie Street.

Gas emergencies, red tags, no-heat, and carbon monoxide alarm calls are covered 24/7. If a CO alarm has sounded, leave the house and call the gas utility first, then call us for the diagnostic and repair.

Custom Homes With Fireplaces, Pool Heaters & Outdoor Kitchens

Richmond Hill has a high concentration of large custom and semi-custom detached homes, particularly through Bayview Hill, Jefferson, and Oak Ridges. These houses often carry several gas appliances on one system: furnace, water heater, one or two gas fireplaces, sometimes a pool heater and an outdoor kitchen. Many also run two-stage central air conditioning across a finished walkout basement and two upper floors.

That appliance count is the thing homeowners underestimate. Every added appliance draws on the same gas supply, and adding a fire table or a generator without re-checking total BTU load can starve the furnace on a cold night. We size the whole system, not just the new line.

Multiple gas fireplaces also mean more venting to inspect. Direct-vent fireplace terminations, blocked or corroded flues, and CO readings are all routine parts of the annual HVAC maintenance visits we run in this housing stock. In the newer townhouses of Rouge Woods and Westbrook, and the condo towers along Yonge Street near Highway 7, cold-climate heat pumps are a growing share of our work. As of 2026, eligible heat pump installs can qualify for rebates of up to $6,500, and we file the paperwork for you.

Reviews

What Richmond Hill customers say

4.9 out of 5 from 150+ customer reviews

We added an outdoor kitchen and they checked the whole gas load first instead of just running a new line. Turned out we needed an upsize, and they explained exactly why.

EElena V.Bayview Hill

CO detector went off at night. They were here within the hour, found a blocked fireplace vent, and cleared it safely. Genuinely reassuring service.

TTerry W.Oak Ridges

Zoned system for a big two-storey with a walkout basement. Careful commissioning and they returned to fine-tune once we lived with it a few weeks.

Local FAQ

HVAC in Richmond Hill: Questions From Local Homeowners

How fast can you respond to an HVAC emergency in Richmond Hill?

Two hours is our target across Oak Ridges, Bayview Hill, Mill Pond, Jefferson, Observatory, and Rouge Woods, with 24/7 dispatch for gas emergencies, red tags, no-heat calls, and carbon monoxide alarms. Highway 404 traffic can affect late-afternoon arrivals in the north end, so we give you a firm arrival time when you book.

My carbon monoxide alarm went off. What should I do?

Get everyone out of the house first, then call the gas utility's emergency line and 911 if anyone feels unwell. Once the property is safe, call us. Our technicians use a calibrated combustion analyzer to find the source, which is usually a cracked heat exchanger, a blocked vent, or a fireplace drafting problem, and we correct it before restoring the appliance to service.

Can I add a gas fire table or outdoor kitchen to my Richmond Hill home?

Yes, once the whole gas system has been checked. Large custom homes often already run a furnace, water heater, two fireplaces, and sometimes a pool heater. We calculate total BTU demand and pipe sizing before quoting, because adding load to an undersized supply can starve the furnace during a cold snap. BBQ hookups run $400 to $1,200 and longer gas line runs $500 to $3,000 at 2026 pricing.

How much does an HVAC service call cost in Richmond Hill?

We price by the job rather than by the hour. A heating diagnostic starts from $150, and most repair service calls land between $250 and $500 at 2026 pricing. You get a written quote before any work begins, so the number does not change while the technician is on site.

What is the most common HVAC problem in Richmond Hill homes?

Clogged furnace filters and the airflow problems they cause are the most frequent call, followed by failed igniters and flame sensors on furnaces, and refrigerant or capacitor faults on air conditioners in summer. In larger custom homes we also see a lot of gas fireplace venting and draft issues. Most of these are caught early with an annual tune-up.

Do you install heat pumps in Richmond Hill?

Yes. Cold-climate air-source heat pumps suit Richmond Hill winters, and dual-fuel setups that pair a heat pump with an existing gas furnace work well in larger detached homes. Installed cold-climate systems run $8,000 to $15,000, and eligible installs can qualify for rebates of up to $6,500, which we file on your behalf.

Do you install zoned systems for large Richmond Hill homes?

Yes. Multi-level custom homes rarely heat and cool evenly from a single zone. We use variable-speed equipment with properly commissioned dampers and a load calculation per zone. We also return after a few weeks of real use to fine-tune the balancing at no extra charge.

Do you clear Enbridge red tags in Richmond Hill?

Yes. Our TSSA G1/G2 technicians handle the full workflow: inspection, leak detection, repair, and the signed clearance Enbridge needs to restore your gas. Red tag inspections start from $350, and most red tags are cleared within 24 hours of our first visit.

How often should gas fireplaces and furnaces be serviced?

Once a year, ideally before the heating season. Annual maintenance covers the furnace burners, heat exchanger, and filter, plus the fireplace pilot and burner assembly, glass gasket, venting termination, and a combustion check. Fireplaces are the appliance homeowners most often skip, and they are a common source of poor draft and CO findings.

Is there an HVAC company near me in Richmond Hill?

Yes. Our technicians cover every Richmond Hill neighbourhood, including Oak Ridges, Bayview Hill, Mill Pond, Jefferson, Observatory, Rouge Woods, Devonsleigh, Westbrook, Richvale, and Crosby, with a two-hour emergency target. We also cover neighbouring Markham and Vaughan, so boundary addresses are never a problem.

Are your Richmond Hill 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.
