Our story
A neighbourhood HVAC shop that works city-wide
Toronto Air Systems was built to give GTA homeowners and property managers one accountable team for furnaces, boilers, air conditioners, heat pumps, and related comfort equipment. We are not a national call centre — when you dial 647 953-4252, you reach people who schedule and dispatch from our Cartwright Avenue shop.
Our technicians hold current Ontario credentials for gas and refrigeration work. That matters on every furnace changeout, boiler service, refrigerant recovery, and code-compliant venting job. Explore how we approach projects on Why Toronto Air Systems, or jump straight to heating and cooling service lines.
Whether you need a same-week repair, a planned high-efficiency upgrade, or help navigating rebates and incentives, we document options in writing so you can decide with real numbers — not pressure tactics.
What matters most for Toronto Air Systems HVAC services in the GTA
Right sizing, licensed gas/refrigeration work, and commissioning beat the cheapest sticker price. We verify airflow, safety devices, condensate paths, and controls so your system does not fail the first extreme week of the season. Ask us about dual-fuel, zoning, and rebate-eligible models during your quote.

Not a call centre
One shop, one accountable team
Toronto Air Systems is dispatched from a single North York shop at 132 Cartwright Ave — not a national franchise routing your call through a queue. The people who answer the phone are the same people who schedule the truck.
That local accountability shapes everything from how we quote jobs to how we handle a callback six months after install.
Why Toronto Air Systems
Why people choose us
Local crews, licensed workmanship, and recommendations built around how Toronto buildings actually heat and cool — not generic scripts.
A real shop, not a call centre
Jobs are planned and crews dispatched from 132 Cartwright Ave in North York. The people who answer the phone are the people who schedule the truck.
TSSA-licensed on every gas connection
Gas and refrigeration work is done by licensed technicians who work to Ontario code and manufacturer requirements — no uncertified subcontractors.
Written pricing before the work
You get the scope, the equipment, the labour and the warranty in writing before any major spend is approved. No verbal estimates that move.
An honest repair-or-replace answer
We quote both and tell you which one we would choose. Sometimes that means talking you out of the bigger job.
The same technicians, visit after visit
A small team means the person who installed it is often the person who comes back to service it, and remembers the building.
Seven days, right across the GTA
Deep-cold heating failures and summer-peak cooling failures do not wait for Monday, and neither do we.
What we do
Everything we look after
One team for the whole building — residential and light commercial, heating and cooling, indoors and out.
Heating
Furnaces, boilers, heat pumps and water heaters — repaired, replaced and maintained for Ontario winters.
Explore heating →Cooling
Central air, ductless and chillers, sized for Toronto humidity rather than for a brochure.
Explore cooling →Commercial HVAC
Rooftop units, make-up air and planned maintenance for buildings that cannot close for the day.
Commercial work →Rooftop units (RTU)
Service, replacement and changeovers on commercial roofs, scheduled around your trading hours.
Rooftop HVAC →Patio & outdoor heating
Infrared heating for restaurant terraces, hotels and back gardens — zoned by where people actually sit.
Patio heaters →Radiant tube heaters
Overhead radiant for warehouses, workshops and bays, where warm air would only ever heat the roof.
Tube heaters →Gas fireplaces
Supply, installation, annual service and the safety checks a gas appliance in a living room needs.
Fireplaces →Snow melting
Hydronic systems for driveways, walkways, entrances and commercial areas — no salt, no shovelling.
Snow melting →Rebates, rental & financing
Programme paperwork handled where one applies, plus rental and payment options on larger replacements.
