A successful energy transformation in Longueuil thanks to AirGreen: how a central heat pump led to 40% savings
In the residential sector of Longueuil, a homeowner recently experienced a remarkable transformation in both thermal comfort and energy expenses. Thanks to the installation of a high-performance central heat pump by our team at AirGreen, he managed to cut his electricity bill by 40%. This article provides a detailed account of this real-life experience, highlighting the technical aspects of the installation, the challenges we overcame, the long-term benefits, and our unique expertise in the HVAC sector in Longueuil.
The context: a typical Longueuil home and a familiar energy problem
The client, owner of a 1980s bungalow in a quiet residential area of Longueuil, was dealing with steadily rising energy costs. His old oil furnace was becoming less and less efficient, and the home suffered from major temperature inconsistencies from room to room. The solution had to be energy-efficient, quiet, and above all, compatible with the existing infrastructure of the house.
After a full on-site evaluation by our experts, we recommended the installation of a high-efficiency Goodman central heat pump, a smart choice combining performance, reliability, and eligibility for Hydro-Québec’s LogisVert rebate program.
Choosing the central heat pump: performance and savings
The central heat pump we installed was a Goodman GSZC18 paired with a Goodman CAPF evaporator coil and a Goodman AVPTC air handler, powered by a variable-speed ECM motor. With a capacity of 36,000 BTU, this heat pump was perfectly suited to meet the heating and cooling needs of this 1,500 sq. ft. home.
Key technical features:
-
Energy Efficiency (SEER): 18
-
Seasonal Heating Performance Factor (HSPF): 10.0
-
Compatible with R-410A
-
Outstanding noise insulation with double-wall cabinet and scroll compressor
-
Smart control with programmable Wi-Fi thermostat
-
Eligible for a $5,000 rebate from combined provincial and federal programs
Thanks to these features, our client immediately noticed a significant improvement in indoor comfort and a measurable drop in energy consumption from the very first month.
Installation process: expertise, precision, and adaptability
The installation was completed over the course of two full days by a team of two certified AirGreen technicians. Here are the key phases of the project:
1. Ductwork analysis
We began with a thorough evaluation of the existing ductwork to ensure it would distribute air evenly throughout the home. Some minor adjustments were needed in the basement area, where warm air was not circulating properly.
2. Removal of the old system
The old furnace was cleanly removed and recycled according to Quebec’s environmental regulations. The space was optimized to accommodate the central indoor unit, which is both more compact and significantly quieter.
3. Installation of the Goodman system
The outdoor unit was installed on a non-slip concrete slab, protected by a snow guard roof and connected to the indoor unit via carefully insulated refrigerant lines. The system was then connected to the existing electrical panel, with the addition of a dedicated 30 A breaker to meet CSA standards.
4. Commissioning and smart configuration
The system was fully commissioned with rigorous pressure testing, leak checks, and airflow measurement. We also configured the Wi-Fi thermostat, enabling intuitive remote temperature control via mobile app.
Client testimonial: comfort and savings delivered
“I was impressed by the professionalism of the AirGreen team. They stuck to the timeline, explained every step, and most importantly, I saw an immediate drop in my heating costs. It’s an investment I’d recommend to all my neighbors in Longueuil.” — Marc G., satisfied homeowner
Rebates and savings: a project that pays off quickly
One of the most attractive aspects of this project was its eligibility for rebates offered by Hydro-Québec and the federal government. Thanks to a certified Energy Star heat pump and installation by a qualified contractor, the client was able to benefit from:
-
$5,000 in combined rebates
-
A green renovation tax credit
-
An estimated $1,200 annual savings on electricity bills
-
A property value increase of 5 to 7%, according to real estate appraisers
Challenges encountered and solutions delivered
During installation, our team had to work around limited space in the mechanical room, along with an undersized old air outlet. We reorganized the ducting and slightly relocated the unit to optimize airflow. These adjustments, while technical, allowed us to maximize the system’s overall efficiency and maintain balanced airflow throughout the entire home.
