A major shift toward energy efficiency: a real story of a successful central installation
At AirGreen, we recently helped a homeowner in Longueuil make a significant change to their heating system. After years of relying on a natural gas furnace, they decided to take the leap and switch to a high-efficiency central heat pump, driven by the desire to reduce energy bills, lower their carbon footprint, and take advantage of Hydro-Québec’s LogisVert grants. Here’s a detailed look at this HVAC installation project that clearly demonstrates the real value of making this transition.
Why replace a gas furnace with a central heat pump?
Many residents of Montreal, Laval, and the South Shore are still hesitant to move away from their gas systems, often due to concerns about upfront costs or lack of knowledge about newer technologies. In this particular case, the homeowner was looking for:
-
A more economical long-term heating solution
-
An eco-friendly alternative to help reduce greenhouse gas emissions
-
An integrated cooling system for increasingly hot Quebec summers
-
A centralized comfort solution to maintain even temperatures throughout the house
After a thorough assessment of the home and the client’s needs, our team recommended a Bosch BOVA 36-IDS Premium central heat pump with R-454B refrigerant, delivering 36,000 BTU of power.
Installation steps: a complete transformation of the HVAC system
Removing the gas furnace
One of the first challenges was the safe removal of the old gas furnace, which was connected to a centralized ductwork system. Our team professionally shut off the gas supply, following all safety standards, and then completely removed the unit. This was also the perfect opportunity to inspect the condition of the ductwork, which we decided to keep and optimize for improved performance.
Installing the new central heat pump
The Bosch IDS Premium outdoor unit was installed at the rear of the home on a raised concrete base, ensuring proper protection from snow accumulation. Thanks to its quiet design and inverter compressor, the unit fits perfectly in a quiet residential neighborhood. Inside, the Bosch air handler unit was connected to the existing duct network using a customized plenum, and electric backup heating elements were added for extreme cold periods.
The entire job was completed in a single day, including refrigerant line installation, electrical hookup, and full system commissioning.
Results and observed benefits
A few weeks after the installation, the client reached out to share their experience:
-
Immediate reduction in energy bills by nearly 40% within the first month
-
Improved air quality thanks to enhanced filtration integrated into the central unit
-
Even thermal comfort in every room of the house, with no cold spots
-
User-friendly system with the smart thermostat included with the Bosch unit
-
Ultra-efficient central air conditioning on hot days, with barely any noise
Grants received and return on investment
One of the key strengths of working with AirGreen is our comprehensive handling of government incentive programs. This project qualified for:
-
$2,500 in LogisVert grants from Hydro-Québec
-
An additional $650 through the Chauffez Vert program, for the gas system removal
We guided the client through the document preparation, the required photo documentation, and the online submission process, which allowed them to receive the funds quickly.
By combining the annual energy savings with the financial incentives, the estimated return on investment for this installation is under 6 years.
Tips for homeowners considering the switch to a central heat pump
Replacing a gas furnace with a central heat pump is a strategic decision, but it should be well planned. Here are some key takeaways from our experience:
-
Have your existing ductwork inspected – in many cases, it can be reused with a few upgrades
-
Choose a system rated for Quebec’s cold climate, such as those certified for -25°C and below
-
Work with a specialized company like AirGreen, which understands local regulations, climate realities, and performance needs
-
Take advantage of grants while they’re still available, as funding levels can change year to year
