Local Knowledge
Toronto houses fight back. That is the job.
Downtown and midtown — the Junction, High Park, Leslieville, the Danforth, Leaside, and the Beaches — are full of century semis and detached homes with narrow lots, tight basements, and duct layouts that were added long after the house was built. The work there is retrofit planning: where runs can go, how returns get back, and what access allows.
North York, Willowdale, Don Mills, Scarborough, and East York hold postwar bungalows and side-splits with original ducting and low headroom. Finished basements, second suites, and additions get added to that same system, so duct and return-air work often changes comfort more than new equipment alone.
We also cover Etobicoke as its own service area, and we handle commercial HVAC for storefronts, offices, and plazas that need work scheduled outside business hours.

Answers before you book.
Quick answers about repairs, replacement, pricing, timing, and working with Navraj Air Systems in Toronto.
Does Navraj Air Systems provide HVAC services in Toronto?
Yes. Navraj Air Systems serves Toronto and the surrounding City of Toronto. We handle furnace installation and repair, air conditioning, heat pumps, ductwork, tankless water heaters, smart thermostats, gas lines, commercial HVAC, and new construction HVAC.
How fast can you help with an emergency furnace or AC repair in Toronto?
We provide 24/7 emergency HVAC repair support. Call 647-669-5009 and we will confirm availability and the next step for your Toronto address.
How much does a new furnace or air conditioner cost in Toronto?
Cost depends on the size of the property, the efficiency level you choose, the condition of the existing ductwork, and access to the mechanical room. We quote after we understand the property, and the quote is free with no obligation.
Should I repair or replace my furnace or air conditioner?
Most systems last about 10 to 15 years. If your equipment is in that range, the repair is a major one, or your bills keep climbing, replacement is usually the better long-term value. We show you both paths and what each one actually solves.
Can you fix uneven temperatures and weak airflow in a Toronto home?
Yes. Uneven temperatures usually trace back to equipment sizing, duct layout, return air, balancing, or controls. We check those first so you are not paying for larger equipment that does not fix the real cause.
Do you install heat pumps in Toronto?
Yes. A heat pump can handle both heating and cooling, and it can be paired with a furnace for the coldest stretches. We will tell you whether your home, ductwork, and electrical setup are a good fit before you commit.
Do you work with builders and commercial properties in Toronto?
Yes. We handle new construction HVAC for custom homes and multi-unit projects, and commercial HVAC for offices, retail, plazas, warehouses, and light industrial spaces in Toronto.
Are your HVAC technicians certified, licensed, and insured?
Yes. Navraj Air Systems works with certified, licensed, and insured technicians for residential and commercial HVAC work.
Do you work on older Toronto homes with limited or no ductwork?
Yes. Older Toronto homes are a core part of our work. We map the existing runs, returns, venting, headroom, and access first, then show you the realistic options and what each one will and will not fix.
