01 — Who we are

Dupont Heating & Air Conditioning Ltd started in 1964. Three generations of technicians, one shop on Dufferin Street, and a simple rule: fix it right the first time. We install and service heating and cooling equipment for homes and businesses across Toronto and Oakville — and when your furnace quits at 2 a.m. in January, we answer the phone.

03 — Two ways to work with us
RESIDENTIAL

Your home, warm in January, cool in July.

  • Installations — furnaces, AC, heat pumps, boilers and hot water tanks, sized and quoted in writing before we touch a wrench.
  • Repairs — diagnostics first, parts second. We explain what failed and why, in plain language.
  • Maintenance — annual furnace and AC tune-ups that keep warranties valid and breakdowns rare.
  • Rentals & financing — spread the cost of new equipment over monthly payments instead of one big bill.
COMMERCIAL

Buildings that cannot afford downtime.

  • Boilers — from multi-residential hydronic heating to large commercial plants, all makes and models.
  • Rooftop units — installation and service for retail, office and warehouse rooftop systems.
  • Hot water — commercial tanks and heating systems installed, maintained and replaced.
  • Custom ductwork — fabricated and installed for efficient airflow across your whole space.
EMERGENCY

Furnace dead at midnight? Call.

  • 24/7 dispatch — a real technician answers, day or night, weekends and holidays.
  • Any make or model — furnace, AC or water heater, we carry common parts on the truck.
  • Fast triage — we stabilize first (heat back on), then plan the permanent fix.
  • Upfront pricing — you approve the number before the work starts, even at 3 a.m.

08 — Questions, answered
Do you offer 24/7 emergency repair?

Yes — around the clock, every day of the year. Furnace, air conditioner or water heater, our technicians are on call nights, weekends and holidays across Toronto and Oakville. Call (555) 010-2030 and a real person answers.

Do you service all makes and models?

Yes. Our technicians work on all major brands of furnaces, boilers, air conditioners and water heaters. We are also an authorized Carrier dealer for new installations.

How often should I service my furnace and AC?

Once a year for each. Annual maintenance keeps manufacturer warranties valid, catches small problems before they become midnight emergencies, and keeps efficiency — and energy bills — where they should be.

Can I finance or rent new equipment?

Yes. We offer equipment rentals and financing options so a new furnace or AC does not have to be one large payment. Ask us for the current terms when you request a quote.

Do you do commercial work?

Yes — it is half of what we do. Commercial boilers, rooftop units, hot water tanks and custom ductwork for small businesses and large buildings, with maintenance plans to keep everything running.
