How Much Does a New HVAC System Cost in the West Island? (2025) A Homeowner’s Guide

Thinking of Upgrading Your HVAC System in the West Island?

Whether your furnace is on its last leg or your AC just can’t keep up with summer heat, upgrading your HVAC system is a smart move — for your comfort, your home’s value, and your energy bills.

But how much should you expect to pay?

This guide gives West Island homeowners a clear breakdown of HVAC system costs, how to choose the right setup, and how to avoid common mistakes when buying.

🏠 What’s the Average Cost of a New HVAC System?

The Quebec government offers major financial incentives to homeowners replacing polluting or inefficient heating systems with clean technologies.

Below are average ranges you should expect when getting quotes for a new system:

System Type

 Average Cost (after government rebates)

Single-Zone Ductless Heat Pump

$2500 – $4500

 Multi-Zone Ductless Heat Pump

$5000 – $12,000

Central Heat Pump

$6000 – $20,000

 

How to tell which you have now:

  • Single-zone ductless: You see exactly one small indoor head on the wall or ceiling.
  • Multi-zone ductless: You see 2 or 3 of those indoor heads, all running off one outdoor box.
  • Central heat pump: You have vents in every room (ceiling or floor registers) and a big outdoor unit.

Please note: that these prices are estimates and can change based on many different factors such as:

  • Type of system (heat pump, furnace, central AC, etc.)
  • Size of your home
  • Efficiency rating
  • Duct work condition
  • Home upgrades required

🏡 How to Choose the Right HVAC System

Every home is different, but here are some common setups for West Island homeowners:

You have duct work and want full electric:

  • Central heat pump
  • Replaces furnace + A/C with one all-electric unit, feeding your existing vents
  • Best for whole-house comfort.

You have duct work and want to keep your gas furnace:

  • Dual-energy (hybrid) system
  • Add a heat pump for most heating needs, and let your gas furnace kick in only on the coldest days.

You don’t have ducts:

  • Single-zone or Multi-zone ductless heat pump
  • One outdoor unit with indoor heads

✅ Step-by-Step: How to Buy an HVAC System the Right Way

Get an estimate

  • Have your HVAC technician evaluate your home and recommend a system.

Think About Your Priorities

  • Are you looking for the cheapest up front cost (saves money now), lowest cost of operation (saves money over time) or best home comfort?

Ask questions

  • An HVAC system is an investment in your home and comfort, don't be afraid to ask for clarification to make the most informed decision possible.

Apply for Grants

  • Programs like Chauffez Vert, Transition Énergétique Québec, and ÉcoPerformance can save you thousands

💸 Government Rebates for West Island Homeowners

  • Up to $22,000 in rebates (ETS system + central heat pump combo)
  • Up to $15,000 for switching from a central gas system to an electric or renewable solution
