Replacing Your Oil Furnace with a Central Heat Pump: What You Need to Know (Grants, Work, Savings)

Upgrading your heating system by replacing an oil furnace with a central heat pump is a major energy transition—but one that brings substantial benefits for homes and buildings across Greater Montréal, Laval, Longueuil, the North Shore, and the South Shore. At AirGreen, we guide our clients through every step of this process to ensure a smooth, cost-effective, and sustainable conversion. This type of project raises many questions: total cost, available grants, equipment choices, project timelines, potential savings, and technical complexity.

A decision that changes everything: why it’s time to say goodbye to oil?

The gradual phasing out of oil furnaces in Québec is no accident. It’s both an environmental and an economic initiative. These systems are not only expensive to maintain, but their efficiency is often inferior to modern technologies like the central heat pump.

Switching to a central heat pump means:

  • Significantly reducing energy consumption.

  • Eliminating GHG emissions from oil usage.

  • Improving year-round indoor comfort.

  • Accessing generous grants.

Available grants: up to several thousand dollars in financial aid

Replacing an oil furnace makes you eligible for several highly advantageous grant programs. Here are the most common:

Hydro-Québec’s LogisVert Program

This program offers substantial amounts—up to $5,000, depending on the system installed and the efficiency of the selected heat pump.

Québec’s Chauffez Vert Program

This program, specifically designed for replacing oil heating systems, can provide up to $1,275 more for tank decontamination, removal, and new electric system installation.

Other possible assistance

Municipalities, CMHC (Canada Mortgage and Housing Corporation), and some federal incentives may supplement this support. At AirGreen, our experts handle eligibility analysis and grant application preparation so you don’t miss any savings opportunities.

Case Study: Successful replacement in Rosemère (North Shore)

A couple owning a century-old home in Rosemère, heated with oil for 40 years, contacted us for a more eco-friendly and cost-efficient solution. Their system was aging, bills were rising, and their outdoor oil tank had a slight leak.

Equipment recommended by AirGreen:

  • Bosch BOVA36HDN1M20G / BVA36WN1-M20 central heat pump (36,000 BTU)

  • Refrigerant: R-454B, variable-speed Inverter technology

  • Seasonal efficiency: SEER 20 / HSPF 10.5

  • Wi-Fi compatible thermostat

  • 240V/60Hz electrical setup

Key project steps:

  1. Safe decontamination and removal of the oil tank.

  2. Full disconnection and dismantling of the existing furnace.

  3. Installation of the new central air handler, integrated with the existing ductwork.

  4. Configuration of the Bosch outdoor unit and refrigerant line connections.

  5. Complete system commissioning, airflow balancing adjustments, performance testing.

Technical challenges:

  • Tight basement access required the furnace to be cut into two sections for removal.

  • Rerouting of the main duct to improve airflow distribution on the upper floor.

  • Electrical system upgrade to meet the power requirements of the Inverter compressor.

Results and benefits:

  • Energy bill dropped by over 45% after a full winter season.

  • Home now completely fossil fuel-free.

  • Optimized comfort thanks to intelligent temperature control.

  • $5,800 recovered through LogisVert + Chauffez Vert programs.

What types of central heat pumps do we recommend?

We prioritize systems recognized for their efficiency, durability, and suitability to Québec’s harsh winters, including:

  • Bosch BOVA IDS Premium (R-454B): Ultra-quiet, high-performance, perfect for furnace replacement.

  • Goodman GMVM97 / GSZC18: Excellent value, known for its ruggedness.

  • Fujitsu KZAH R-32: Reliable Japanese technology, ideal for homes with existing ductwork.

  • Trane XV18: High-end performance, especially appreciated in larger residential buildings.

Installation: what to expect?

A complete installation usually takes 2 to 4 days, depending on project complexity. We take care of:

  • The initial assessment of your current system.

  • Environmentally responsible removal of the old equipment (tank, furnace).

  • Installation of the new central system (ductwork, outdoor unit, electrical hookups).

  • All administrative steps related to grants.

  • System calibration and post-installation follow-up to ensure optimal performance.

Practical tips for a successful transition

1. Plan ahead

Grant delays and project coordination can take several weeks, especially during peak periods (spring-summer).

2. Assess your ductwork quality

A poorly designed or dirty duct system can impact your new heat pump’s performance. We often recommend a full cleaning or ductwork upgrade.

3. Choose a certified installer

Our technicians are TEQ-certified, trained on high-efficiency systems, and experienced in complete oil system replacements.
