A central heat pump designed for Quebec's climate, not for a generic catalogue
At AirGreen, we install central heat pump systems in real conditions, often complex, sometimes imperfect, but always representative of Quebec's housing stock. Single-family homes from the 1950s to the 1980s in Montreal, renovated bungalows in Laval, newer construction on the South Shore, multi-unit buildings on the North Shore: every building comes with its own mechanical, thermal and electrical constraints.
The CANAIR R410A ADD ON Central Heat Pump | 30000 BTU - Cased Coil answers these realities with a clear goal: stable, reliable heating, even when temperatures drop sharply, while fitting smartly into existing HVAC installations.
The ADD ON concept: a realistic, economical approach
Why the ADD ON format matters in Quebec
Many of the projects we handle at AirGreen involve buildings that already have an electric furnace or an older central system. In these situations, replacing the whole HVAC system is not always logical or financially justified.
The ADD ON format lets you:
Add an efficient central heat pump to an existing installation
Keep the ductwork after a technical check
Reduce invasive work and overall costs
Improve comfort and energy efficiency
A solution suited to renovations and targeted replacements
This model is particularly relevant for:
Replacing an old central heat pump at the end of its life
Adding a central heat pump to an existing electric furnace
Modernizing an HVAC system without major changes to the ducts
Heating capacity you can really use in winter
30,000 BTU that count when it is cold
The nominal size of 30,000 BTU (2.5 tons) suits many typical single-family homes in Greater Montreal. But beyond the number, it is the real capacity in cold conditions that makes the difference.
According to NEEP data for this ENERGY STAR® cold climate certified system (AHRI 211644140), it delivers:
22,600 BTU/h at -8°C (COP 2.62)
27,000 BTU/h at -15°C (COP 1.85)
up to 18,600 BTU/h at -30°C (COP 1.5)
This keeps comfort steady without switching too early to heavy electric backup. In deep cold, the furnace's electric element covers the share of heat that is missing.
Temperature stability and even comfort
Inverter modulation lets the system hold its output without excessive cycling, even during long cold periods, which helps keep temperatures more even between floors.
Controlled efficiency and running costs
Ratings that match real-world use
This central heat pump delivers solid seasonal performance:
SEER2: 15.5
EER2: 10.5
HSPF2 (region IV): 9.7
These values translate into lower electricity use for heating, especially in the shoulder seasons and moderate cold, which make up a large part of the Quebec winter.
Hydro-Québec LogisVert aid
This combination (AHRI 211644140) is on Hydro-Québec's LogisVert list of October 27, 2026, with an indicative amount of $2,712. Only Hydro-Québec confirms the aid granted. At AirGreen, we support our clients at every step:
Checking technical eligibility
Reviewing the existing configuration
Preparing the required documents
Components designed for durability
Side-discharge outdoor unit: a real advantage in the field
The CDH2030C21 outdoor unit stands out for its side-discharge format, particularly appreciated in urban settings:
Narrow backyards
Tight spaces between buildings
Wall-bracket or slab installations
With a sound level of about 62 dB(A), it stays discreet, even in densely populated areas.
Cased coil
The MAC-36HWFN1-M cased coil (21 × 21 × 24 in.) is installed on the existing furnace, and the furnace blower moves the air across the coil. AirGreen checks and adjusts that airflow at start-up.
Installation is possible:
Vertically
Horizontally
With easy access to the coil for HVAC maintenance
This flexibility helps in tight mechanical spaces, which are common in multi-unit buildings.
Why a rigorous HVAC installation matters
What we always check at AirGreen
An efficient central heat pump only delivers good results if the installation is done right. Before every project, our teams check:
The ductwork's actual airflow (CFM)
The external static pressure
The condition and airtightness of the ducts
The available electrical capacity (MCA 23 A, MOP 35 A)
When these checks are skipped, the result is often noise, early wear or lower-than-expected performance.
An approach built on field experience
Every installation we complete deepens our understanding of Quebec buildings. That accumulated experience lets us anticipate difficulties before they appear and adapt each project to the client's situation.
Who is this central heat pump for?
The CANAIR R410A ADD ON Central Heat Pump | 30000 BTU - Cased Coil is particularly suited to:
Owners who want to modernize an existing central system
Single-family homes in Montreal, Laval and Longueuil
Projects looking for a good balance of cost, performance and durability
Clients who want a reliable system without needless complexity
Why choose AirGreen for this type of project
At AirGreen, we do not sell models out of habit. We recommend this system when the building, its real use and the client's expectations line up.
Our added value rests on:
Experienced refrigeration technicians, under AirGreen's RBQ licence 5645-9605-01
An on-site technical assessment before every installation
Complete support, including post-installation follow-up
A transparent approach, with the price confirmed before the work
