Furnace Installation in the GTA (2026 Guide)

Key Takeaways

Direct Air Systems installs new high efficiency gas furnaces and heat pumps across the GTA, with offices in Bolton and a live-fireplace showroom in Markham.

Most furnace installation projects in Toronto and York Region range from about $4,500–$10,000+ before rebates, depending on size, efficiency, and ductwork.

Lennox high efficiency furnaces (up to 99% AFUE) and ENERGY STAR heat pumps can qualify for Canada Greener Homes and Lennox seasonal rebates worth up to several thousand dollars combined.

A professional furnace installation typically takes one day after a free in-home assessment, assuming no major duct changes or gas line relocation.

Introduction: Furnace Installation with Direct Air Systems Ltd.

Furnace installation is one of the most consequential decisions a GTA homeowner makes. Direct Air Systems Ltd. provides professional furnace installation and replacement across Toronto, York Region, Peel, and surrounding areas - backed by over 30 years of hands-on experience. Founded by Jack Shahi, Direct Air Systems is a full-service HVAC and fireplace company, an authorized Lennox Premier Dealer.

Choosing the Right Furnace or Heat Pump for Your GTA Home

Gas furnaces are the most popular heating option in Canada. Many GTA homeowners now pair a high efficiency gas furnace with a cold-climate heat pump for shoulder-season savings. According to Natural Resources Canada, high-efficiency furnaces can reduce heating energy consumption by up to 25% compared to older equipment. A typical detached GTA home needs 60,000–100,000 BTU of heating capacity.

Gas Furnaces, Heat Pumps, and High Efficiency Options

Direct Air installs primarily natural gas furnaces and high efficiency furnaces, and increasingly cold-climate heat pumps as part of hybrid systems. High-efficiency furnaces achieve efficiency ratings over 95% AFUE, with the Lennox SLP99V pushing 99%. These units use PVC or CPVC pipes for venting rather than traditional metal chimneys.

What to Expect During Professional Furnace Installation Day

A furnace installation is typically performed by licensed HVAC contractors to avoid safety risks. Here is what a typical installation day looks like with Direct Air Systems:

  • Pre-work walkthrough — The lead technician reviews the work order, confirms the furnace model and placement, and checks existing ductwork and electrical/fuel lines for code compliance.
  • Removing the old furnace — The installer disconnects and safely removes the existing unit, including old gas lines, electrical wiring, and venting.
  • Preparing connections — A licensed gas fitter connects the gas supply line with a sediment trap and shut-off valve.
  • Setting the new furnace — The new system is positioned, levelled, and secured. Ductwork modifications happen if the new unit differs in size.
  • Venting and condensate — High-efficiency units require PVC venting; condensate drains are routed to a floor drain.
  • Testing and clean-up — Gas pressure tests, airflow checks, and carbon monoxide verification. The team demonstrates thermostat controls and leaves full documentation.

    After Your New Furnace: Maintenance, Filters, and When to Consider Replacement

    Even the best furnace or heat pump system needs regular maintenance. Typically an annual professional tune-up for gas furnaces, with filter changes every 1–3 months. A furnace’s lifespan for modern high efficiency models is generally 15–20 years with proper maintenance. Warning signs include rising heating bills, frequent repairs, uneven temperatures, and loud operation.

    Frequently Asked Questions

    How long does a furnace installation actually take in a typical Toronto home?

    Most straightforward gas furnace installation jobs take 6–8 hours, or roughly one full working day. If the installation requires gas line relocation, venting changes, or zoning work, it can extend to about 1.5 days. Emergency replacements can sometimes be scheduled next-day depending on equipment availability.

    Do I need a permit or inspection for a new gas furnace in the GTA?

    Yes. Many local municipalities — including Toronto, Vaughan, and Markham — require a permit and post-installation inspection for furnace replacement. See TSSA Ontario for gas installation licensing requirements. Your contractor should handle permit applications.

    Is a two-stage furnace worth it compared to a single-stage model?

    For most GTA homes, yes. A two-stage furnace runs at reduced output most of the time, delivering quieter operation and more even heat. The difference in cost is typically a few hundred to a couple of thousand dollars, and most homeowners find the comfort improvement well worth it.

    Can I install a new furnace myself to save money?

    This is not recommended. Gas furnace installation requires connecting natural gas lines, verifying proper venting, and performing leak testing — work that must comply with the Ontario Building Code and TSSA regulations. Improper installation can lead to gas leaks and carbon monoxide exposure.

    What brands of furnaces does Direct Air Systems install?

    Direct Air is an authorized Lennox Premier Dealer and installs the full Lennox furnace lineup — from the Merit and Elite series to the Signature Collection SLP99V at up to 99% AFUE.

    Should I replace my air conditioner or heat pump at the same time as my furnace?

    If your air conditioner is more than 12–15 years old, replacing it alongside your furnace often makes sense. Bundling with a heat pump can reduce labour costs and ensure matched components for best performance.

    Conclusion and Next Steps

    A properly sized, professionally installed high efficiency furnace is one of the most important investments for GTA comfort and safety. Plan your furnace replacement before a mid-January breakdown limits your options. Get a free quote — no obligation, no pressure.
