Get Free QuotesWhat a New Furnace Actually Costs in Hamilton
The number that matters isn’t the sticker price on the furnace itself β it’s the all-in installed cost, which is what Hamilton homeowners actually pay. For a standard swap of an aging furnace in a typical Hamilton detached home, most homeowners spend betweenΒ $3,800 and $6,500Β for a high-efficiency 96% AFUE unit. The range widens considerably based on venting requirements, electrical modifications, and whether the existing ductwork needs adjustments.
Two things drive Hamilton furnace costs higher than the equipment price alone: venting and permits. High-efficiency furnaces use PVC sidewall venting rather than a chimney β homes switching from an old 80% unit to a 96% model often need new PVC vent runs, which can add $400β$900. City of Hamilton mechanical permits are required and run $150β$400.
| System Type | AFUE | Installed β Hamilton | Notes |
|---|---|---|---|
| Standard Single-Stage | 80% | $2,800 β $4,500 | Chimney venting; cheaper if chimney liner already exists |
| High-Eff. Single-Stage | 92β96% | $3,800 β $6,000 | PVC sidewall vent; most common Hamilton install |
| High-Eff. Two-Stage | 96% | $4,500 β $6,800 | Better comfort; runs at 65% most of the time |
| Variable-Speed High-Eff. | 96β98% | $5,200 β $8,500 | Quietest, best dehumidification, premium comfort |
| Cold-Climate Heat Pump | Equiv. 200β300%+ | $5,500 β $14,000 | Heats + cools; qualifies for major rebates |
| Goodman High-Eff. (house brand) | 96% | $3,600 β $5,500 | Value tier β strong warranty, Hamilton dealer available |

Everything That Goes Into a Hamilton Furnace Quote
A single-line quote from a Hamilton contractor tells you almost nothing. Here’s what a complete furnace installation involves β and what to ask about on each item.
π© Equipment Cost
The furnace unit itself β the largest variable. An 80% AFUE single-stage might be $1,200β$1,800; a premium variable-speed 98% AFUE can be $3,500+. Brand, warranty length, and efficiency tier drive the spread.
π· Labour
Hamilton HVAC technician rates: $95β$140/hour. A straightforward furnace swap takes 4β6 hours; a new installation with modified ductwork or electrical can take a full day. Expect $600β$1,200 in labour on a typical job.
ποΈ Venting & Flue Work
Switching from an 80% to a 96% furnace means abandoning the chimney flue and running new 2-inch PVC sidewall venting. Depending on furnace location and run length, this adds $400β$900. Confirm it’s itemized in your quote.
π City of Hamilton Permit
Required for all furnace installations and replacements in Hamilton. Expect $150β$400 in permit fees. The permit triggers a city inspection β which protects you, not just the contractor. Never skip it.
π Gas Line & Electrical
Existing gas lines are typically reused. Modifications add $200β$600. Furnaces require 120V electrical; newer high-efficiency models may need a dedicated circuit if the existing setup is outdated.
ποΈ Old Furnace Removal
Disposal of the old unit β including any residual fuel handling β is typically included by reputable contractors. If it’s not explicitly mentioned, ask. Removal and disposal alone can run $150β$300 if added after the fact.
Hamilton Furnace Pricing by Neighbourhood Type
Where your home sits in Hamilton matters more for furnace installation than it does for most trades. Lower-city homes β Corktown, Beasley, Crown Point β often have older mechanical rooms, narrower access, higher ceilings, and gravity-era ductwork that can complicate installation. Mountain-area homes in Ancaster, Dundas, and Waterdown typically have more standard 1990s-to-2010s construction that involves fewer complications and predictable pricing.
| Home Type | Typical Complications | Cost Impact |
|---|---|---|
| Pre-1960 lower-city (brick semi, row) | Tight access, chimney-dependent, old duct sizing | +$400 β $1,200 above standard |
| 1960β1980 bungalow / backsplit | Generally straightforward; may need duct sealing | Near standard pricing |
| 1980β2000 two-storey detached | Usually clean swap; standard venting routes | Standard pricing range |
| 2000β2015 Ancaster / Waterdown | Very clean; often high-eff. already | Lower end of range |
| Mountain-area multi-level (split) | Duct balancing may be needed | +$200 β $600 if duct work required |

Common Questions About Furnace Costs in Hamilton
Why did two Hamilton contractors quote me $3,000 apart?
Because they’re almost certainly not quoting the same product. A Goodman 80% AFUE single-stage unit costs significantly less than a Lennox or Carrier 96% AFUE two-stage unit β both are legitimate furnaces, just different performance tiers. Always compare AFUE rating, brand, stage count (single vs. two-stage vs. variable), warranty terms, and exactly what’s included (permit, venting work, disposal). A $3,000 price gap often reflects a meaningful performance and efficiency difference, not just margin-padding. Ask each contractor to itemize their quote.
Is a 96% AFUE furnace worth the extra cost in Hamilton?
For most Hamilton homeowners, yes β with the right timeline. An 80% AFUE unit converts 80Β’ of every $1 of gas into heat; a 96% unit converts 96Β’. On a typical Hamilton Enbridge bill running $1,800β$2,400/year in gas, a 96% AFUE furnace saves $250β$450 annually compared to an 80% unit. The premium for the high-efficiency model is typically $800β$1,500 over the standard unit. Payback runs 3β6 years β excellent for anyone planning to stay in the home, and better still with Enbridge rebates that reduce the premium cost.
What happens to my chimney when I install a 96% furnace?
High-efficiency furnaces produce flue gases too cool to draft properly through a masonry chimney β they must use PVC sidewall venting instead. Your chimney becomes unused for furnace exhaust, though it may still serve a water heater or fireplace. If the chimney served both the furnace and water heater, a new liner may be required for the water heater alone. A reputable contractor will assess this before starting work and include any required chimney liner work in their quote.
