Old Furnace Removal Cost: Toronto Pricing & Disposal Guide

If you're replacing an old furnace in Toronto, you're wondering what it costs to get the old one out — and whether there's any scrap value left in it. This guide breaks down furnace removal costs in Toronto, what affects the price, and what to expect from the process.

What Does Old Furnace Removal Cost in Toronto?

• Bundled with new installation: Most HVAC contractors include old furnace removal. Ask explicitly — some charge separately.
• Standalone HVAC contractor removal: $150–$350 depending on complexity and access.
• Scrap metal pickup (free): For disconnected, accessible furnaces at ground level. Scrap metal value covers the pickup cost.
• Premium Plus service: Tight basement or same-day need — $75–$200 depending on situation.

What Affects the Cost?

Location in the Home

An accessible utility room furnace is straightforward. One in a crawlspace or narrow basement with a tight stairwell adds significant labour. Harder access = higher cost.

Type of Furnace

Standard gas forced-air furnaces are most common and easiest. Oil furnaces may involve decommissioning a tank. Electric furnaces are simpler but heavier. High-efficiency condensing units have extra PVC venting and drainage connections.

Asbestos — Critical for Pre-1985 Furnaces

Older furnaces, especially those with duct wrap or plenum insulation from before 1985, may contain asbestos. If there's grey, fibrous, or crumbly insulation on ducts or the plenum box, stop and get a professional assessment before disturbing it. Asbestos abatement in Toronto runs $500–$2,000+ and must be done by a licensed contractor.

What's Inside an Old Furnace (Scrap Metal Value)

A typical gas forced-air furnace contains:

• Steel cabinet and chassis — the bulk of the weight (100–200 lbs)
• Heat exchanger — heavy-gauge steel or stainless steel
• Copper wiring and fittings — small but valuable
• Aluminum components — blower housing, some fin sections
• Brass gas valves and fittings

Total scrap value on a typical residential furnace: $15–$40. Enough to offset the pickup cost — which is why free pickup works for accessible units.

How Furnace Removal Works

1. Turn Off Gas and Power

Gas supply must be shut off and the line capped by a licensed gas fitter. The electrical circuit must be off at the breaker. Do not disconnect gas lines yourself in Ontario — this requires a licensed technician.

2. Disconnect Venting

The exhaust flue from furnace to chimney must be disconnected. For high-efficiency units the PVC vent pipes are easy; for conventional units the metal flue may require some manoeuvring.

3. Disconnect Ductwork

Supply and return air plenums connect to ductwork via sheet metal and screws. Once disconnected, seal open duct ends to prevent air loss.

4. Move and Dispose

A residential furnace weighs 100–200 lbs. Use a hand truck and get a helper. Navigating basement stairs is the main challenge. Once at ground level, it's ready for pickup or yard drop-off.

Summary

Furnace removal in Toronto is typically free when bundled with a new HVAC installation. Standalone removal runs $150–$350 from an HVAC contractor, or free for accessible disconnected units through a scrap metal pickup service. Always check for asbestos on pre-1985 furnaces before disturbing any insulation.
