A major renovation project is the perfect opportunity to improve comfort, energy performance, and property value. However, integrating a central heat pump into such a project comes with specific challenges. At AirGreen, we support dozens of homeowners every year in Montréal, Laval, Longueuil, on the North Shore and the South Shore, ensuring the smooth integration of HVAC systems during complete home makeovers. Drawing from our field experience, here are five essential tips to avoid headaches and make the most of a central heat pump when undertaking a large-scale renovation.
Understanding the Benefits of a Central Heat Pump During a Renovation Project
Installing a central heat pump in a home undergoing transformation offers several advantages:
-
Increased energy efficiency: A modern central heat pump like the Bosch BOVA IDS Premium (R-454B) or the Goodman R-32 can deliver substantial savings on heating and cooling costs.
-
Even comfort throughout the home: Uniform air distribution thanks to a properly sized duct system.
-
Access to grants: Several programs such as Hydro-Québec’s LogisVert offer generous incentives for energy-efficient renovations.
1. Plan the HVAC Integration From the Design Phase
One of the most common mistakes in renovation projects is leaving the HVAC system for the last minute. It is crucial to consider HVAC planning from the very start of the project:
-
Coordination with the architect: Strategic placement of the indoor unit (air handler or furnace) and the ductwork.
-
Dedicated mechanical room: Allocate a properly ventilated technical area to house the indoor unit and facilitate maintenance access.
-
Heat load calculation: Our experts carry out a detailed thermal study to properly size the central heat pump based on the home’s new characteristics (insulation, windows, orientation).
2. Choose the Right Equipment Based on Surface Area and Needs
Every home is unique, especially after renovations that often change room layout or insulation materials. The central heat pump you choose must be perfectly suited:
Examples of Units Installed by AirGreen
-
Goodman GMVM97 + GSZC18: Ideal for single-family homes over 2,000 sq. ft., this two-stage system offers excellent performance for its price.
-
Bosch BOVA IDS Premium (R-454B): Ultra-quiet inverter technology, superior energy efficiency, and eligibility for multiple grants.
-
Fujitsu KZAH R-32: Compact, discreet, and efficient—perfect for semi-detached or row homes.
We always recommend a brand and model tailored to the property type, budget, and client’s energy-saving goals.
3. Anticipate the Technical Challenges of a Renovation
Major renovations rarely come without surprises. Adding a central heat pump system requires precise expertise:
-
Routing ducts through existing structures: At AirGreen, we’ve installed flexible insulated ducts through drop ceilings, brick walls, and even between floor joists—without compromising the home's aesthetics.
-
Electrical panel upgrades: Adding a heat pump sometimes requires increasing your panel’s capacity. We coordinate with certified electricians to ensure full compliance with Quebec’s building code.
-
Minimizing noise disturbances: Our technicians install anti-vibration mounts, duct silencers, and place the outdoor units away from living areas.
4. Coordinate the Work With Other Trades
Installing a central heat pump in the midst of a renovation requires excellent scheduling:
-
Before closing the walls: All ductwork must be installed before drywall to avoid costly do-overs.
-
In harmony with finishing work: We use sleek air diffusers and discreet return grilles that blend seamlessly with your interior design.
-
Meeting project timelines: We align our installation schedule with that of the general contractor to prevent any delays.
5. Take Advantage of Available Grants
An intelligent energy-efficient renovation that includes a central heat pump qualifies for multiple financial assistance programs:
-
LogisVert – Hydro-Québec: Up to $5,000 depending on installed capacity and model.
-
Rénoclimat Grant: For homeowners who have their property evaluated before and after the renovation.
-
Federal “Greener Homes” Grant: Up to $10,000 in reimbursement for high-efficiency systems.
We guide our clients through every administrative step to make sure they receive all eligible support, quickly and hassle-free.
AirGreen Case Study – Renovation Project in Longueuil
Recently, we integrated a Bosch BOVA IDS Premium 36,000 BTU central heat pump into a 1970s home undergoing major renovations in Longueuil. The main challenge was the limited basement space available for ducts and the air handler. Our technicians designed a compact duct layout with optimized airflow distribution. The homeowner wanted even comfort upstairs, which we delivered using a zoned system with independent thermostat controls. The installation was completed in 4 business days, and we handled the entire LogisVert grant application. The result: a satisfied client, superior comfort, and a 34% drop in energy consumption during the first season.
