Performance, reliability and efficiency: our installation of a 5-ton ACD central heat pump in Longueuil for total indoor comfort
Longueuil, a vibrant city on the South Shore, experiences increasingly hot summers and harsh winters. For homeowners and building managers alike, this brings a clear need: to equip their property with an HVAC system that maintains ideal temperatures all year round without compromising energy consumption. In this context, we carried out the installation of a 5-ton ACD central heat pump in a single-family home in the Vieux-Longueuil area — a tailor-made solution focused on performance, durability, and energy efficiency.
Why the customer chose a 5-ton ACD central heat pump
The homeowners were looking to replace their old oil heating system, which had become inefficient and costly. They were in search of an eco-friendly solution that would qualify for the Hydro-Québec LogisVert grants, and most importantly, one that could evenly heat and cool all 2,800 sq. ft. of their open-concept home.
After a full technical evaluation performed by our team, the recommended model was a 5-ton ACD central heat pump, a high-performance option ideal for large spaces with an excellent quality-to-price ratio.
Technical specifications of the installed ACD central heat pump
We installed an ACD system – 60,000 BTU (5 tons), known for its strength and reliability. Here are its main features:
-
Capacity: 60,000 BTU/h (perfect for large homes or duplexes)
-
Refrigerant: R-410A (efficient and stable)
-
Energy efficiency: SEER rating of 16, HSPF rating of 9.5
-
Compatible with existing ductwork
-
Quiet operation: variable-speed compressor
-
Includes smart thermostat: weekly programming and remote control
The system is eligible for the LogisVert grant, which allowed the clients to receive $5,000 in financial assistance.
Project stages: AirGreen’s complete approach
Full thermal evaluation and tailored adaptation to the client's needs
From the start, our team performed a complete thermal diagnosis of the home. In addition to load calculations, we inspected the existing duct system, measured airflow room by room, and identified problem areas from the old system.
We then designed a fully customized solution, integrating the ACD heat pump into the duct network with several modifications to improve the distribution of warm and cool air.
Installation process: precision and efficiency
The installation took two full days, scheduled in advance with the client. Here are the key steps completed by our AirGreen team:
-
Safe removal of the old oil furnace
-
Connection of the new ACD unit to the central air handler
-
Inspection and adjustment of the ductwork to ensure optimal airflow
-
Installation and calibration of the smart thermostat
-
System startup, pressure checks, noise and vibration testing
-
Customer training on system usage and maintenance
Technical challenges we faced
The existing ductwork was partly made of older galvanized metal, poorly insulated, which risked thermal losses during the winter. To address this, we insulated certain sections and replaced two main branches to optimize performance.
Additionally, part of the basement — often humid — needed a ventilation adjustment. We added a dedicated air vent to enhance comfort and efficiency.
Measurable results: even comfort and reduced energy bills
After 30 days of use, the customer reported:
-
Stable temperatures in every room, even upstairs
-
An estimated 35% reduction in energy consumption
-
No noticeable noise from the compressor, even at full capacity
-
Full control via the connected thermostat, allowing customized scheduling based on their daily routine
According to their first Hydro-Québec bills, switching to the ACD central heat pump is expected to pay for itself in under 6 years, including the grant received.
