Frequently Asked
Toronto Heating Services Questions
What heating services do you cover in Toronto?
Full-lifecycle heating: high-efficiency gas and electric furnace installation and repair, condensing combi and system boiler installation, hydronic radiant in-floor heating, cold-climate air-source heat pump installation with rebate paperwork, emergency no-heat dispatch 24/7, and annual maintenance plans. Every technician holds a TSSA G1 or G2 gas licence, and we handle both residential and commercial heating work across Toronto and the wider GTA.
What is the typical cost of a new furnace installation in Toronto?
High-efficiency condensing gas furnace installation in Toronto typically runs $3,500 to $7,500 installed, depending on AFUE rating (95-98% AFUE), single-stage vs two-stage vs modulating configuration, ductwork correction requirements, and PVC venting complexity. Ontario Home Renovation Savings (HRS) Program pays $250-$1,000 back on qualifying installations. Boilers run $5,500-$15,000 depending on type. Heat pump installations run $8,000-$18,000 before rebates of up to $7,500 through HRS.
How fast can you respond to a no-heat emergency?
Emergency no-heat calls in Toronto and the GTA get 24/7 live phone answering with a target 2-hour on-site response window. Most winter no-heat calls are diagnosed within 30 minutes of arrival and repaired same-visit because our technicians carry common failure parts on the van: hot surface igniters, flame sensors, pressure switches, capacitors, limit switches, and thermostats. Cold-snap dispatch capacity is held for the coldest 10 days of the year when call volume spikes.
What Ontario heating rebates are currently available?
Three programs stack on eligible high-efficiency heating installations in 2026. The Home Renovation Savings (HRS) Program pays $250-$1,000 on ENERGY STAR condensing furnaces, $2,000 for dual-fuel heat pump hybrids, and up to $7,500 for full electric cold-climate heat pump replacements. Canada Greener Homes Loan offers up to $40,000 interest-free financing for qualifying retrofits. Toronto BetterHomesTO HELP program offers up to $125,000 at low interest repayable through property tax over 15 years.
Do you handle both residential and commercial heating?
Yes. Our TSSA-certified crew handles residential furnace and boiler work across single-family homes, semis, and condos, plus commercial heating for restaurants, retail, offices, and light industrial facilities. Commercial work includes rooftop unit (RTU) service, make-up air units, and planned maintenance agreements. The same crew handles both scales so specification and code compliance stay consistent.
How do I choose between a furnace and a heat pump for my Toronto home?
The decision depends on your fuel connection, electrical panel capacity, home envelope, and operating cost preference. Homes with an existing gas connection usually go with a dual-fuel hybrid (heat pump for temperatures above balance point, gas furnace for cold snaps below) to leverage both fuels. Homes without gas or wanting full electrification typically go with a standalone cold-climate heat pump plus electric strip backup. We run Manual J heat load calculation and bill history analysis on every quote to model both configurations against your specific home.
What warranty comes with your heating installations?
Every heating installation is registered with the equipment manufacturer, and the applicable manufacturer parts warranty (typically 5-10 years on the equipment, up to 20 years on heat exchangers for premium furnaces) is provided in writing at completion with model numbers, serial numbers, and coverage terms clearly stated. Any workmanship coverage is confirmed on your specific quote before work starts.
Do you offer heating maintenance plans?
Yes. Our HVAC Maintenance Plans include biannual furnace and AC tune-ups, priority scheduling during heat waves and cold snaps, discounted repair pricing (10-20% depending on tier), and no diagnostic fee on emergency calls for premium tier subscribers. Plans start at $199/year for basic coverage and up to $499/year for premium with 24/7 emergency response. Plans typically pay for themselves through one tune-up + one repair discount per year.
