A central heat pump designed for Quebec's real climate, not for marketing spec sheets
At AirGreen Heat Pumps, Air Conditioning & Heating, we install and maintain central HVAC systems in very real conditions: long winters, intense cold, prolonged freezing periods, large swings in heat load and buildings that aren't always energy-efficient. In this context, a central heat pump must do much more than perform well on paper.
The CANAIR R410A ADD-ON Central Heat Pump | 36,000 BTU – Cased Coil is a robust, stable add-on central system that provides heating down to -30°C while delivering efficient, steady cooling in summer. This model is particularly well suited to single-family homes, duplexes, triplexes and small multi-unit buildings in Montreal, Laval, Longueuil, the North Shore and the South Shore, where heating needs are high and long-term reliability is a priority.
Real heating performance: stability, continuity and endurance
Efficient central heating even in very cold weather
One of the great advantages of this CANAIR central heat pump is its ability to keep high heating output at very low temperatures. According to the NEEP data for this ENERGY STAR® cold climate certified system (AHRI 211644138), this means:
33,000 BTU/h at -8°C (COP 2.4)
32,000 BTU/h at -15°C (COP 2.0)
Working heat down to -30°C, with a maximum capacity of 24,000 BTU/h (COP 1.42)
A central solution designed for Quebec winters
Because it keeps its capacity in deep cold, this model is a relevant choice for homeowners who want to reduce their reliance on backup systems while keeping even comfort throughout the house. In deep cold, the furnace's electric element covers the share of heat that is missing.
Balanced, comfortable central cooling in summer
In cooling mode, the 36,000 BTU (3-ton) capacity efficiently covers large areas without excessive cycling or sudden temperature changes. Variable-speed operation promotes:
A more even indoor temperature
Better humidity control
Steady comfort, even during long heat waves
It is also a good option to replace an older central unit that is oversized or poorly matched, often the cause of discomfort, noise and excessive energy use.
Inverter technology: continuous comfort and less wear
Built-in inverter technology plays a key role in how this central heat pump behaves. Rather than running in frequent on/off cycles, the system continuously adjusts its output to actual demand.
The benefits are tangible:
Fewer temperature swings
Less mechanical noise
Less component wear
Better acoustic comfort, indoors and outdoors
This model suits dense residential areas, small backyards and installations near outdoor living spaces such as patios and terraces.
A truly flexible add-on system for replacements
Smart integration with existing systems
The CANAIR R410A ADD-ON Central Heat Pump is designed to integrate efficiently with existing ductwork, making it a preferred solution for:
Adding a heat pump to an existing furnace
Replacing an old central air conditioner
Upgrading old central heat pumps
The cased coil is installed on the existing furnace and makes long-term maintenance and inspection easier.
At AirGreen, every project starts with a complete analysis of the ductwork: airflow, static pressure, airtightness, balancing and overall compatibility. A high-performance heat pump that is poorly integrated can lose a significant share of its efficiency, which is why this step is essential.
Side discharge: a real advantage in the field
The side-discharge format offers several practical advantages:
Smaller footprint
Easier installation on a base or slab
Better fit in tight spaces
Easier handling during installation

At AirGreen, we support our clients in Montreal, Laval, Longueuil, the North Shore and the South Shore:
Checking the model's eligibility
Installation compliance
Documents needed for your application
HVAC maintenance: preserving performance over time
Even a high-quality central system needs regular HVAC maintenance to keep its performance. The most common faults seen in the field include:
Clogged filters restricting airflow
Dirty coils reducing heat exchange
Poor central thermostat settings
AirGreen recommends preventive maintenance every 12 to 18 months, including inspection, cleaning, electrical checks and calibration.
