Outdoor unit
One compressor for the whole house. It supplies up to 4 heads and modulates from 10,000 to 35,200 BTU/h depending on what the rooms call for (NEEP).
Base pan heater
A heater keeps the outdoor unit’s base pan free of ice below 1 °C and during defrost (NEEP).
Refrigerant lines
One pair of lines per head.
Indoor heads
One head per room, each with its own remote and temperature. The combination is chosen in the “Zones” menu.
Control
Each zone is set separately.
Turn rooms on and off. Watch the power being shared.
One outdoor unit supplies every head: when several rooms call at once, they share its capacity. Pick an outdoor temperature.
Tell us your rooms. We tell you if this size is enough.
Pick the number of rooms and their size. The estimate targets a −15 °C day; it is a guide, the real calculation is done room by room at your home.

A Multi-Zone HVAC Solution Designed for Quebec's Harsh Winters
At AirGreen, we regularly install multi-zone systems in residential properties and small apartment buildings in Montreal, Laval, Longueuil, on the North Shore, and the South Shore. The 2-zone DIRECT AIR HEAT XTREME PRO (-35°C) heat pump with a 36,000 BTU outdoor unit is one of the models we recommend when our clients are looking for an optimal balance between extreme winter performance, installation flexibility, and energy efficiency.
This system is specifically designed to operate in harsh climatic conditions, with heating capacity maintained down to -35°C, an essential feature in our Quebec reality.
Real Heating and Cooling Performance: Beyond the Numbers
Capacity tailored to the real needs of Quebec homes
With a nominal capacity of 36,000 BTU, this heat pump is ideal for:
- Medium-sized single-family homes
- Duplexes or triplexes with distinct zones
- Condos with differentiated needs (living room + bedrooms)
In practice, we recently installed this model in a duplex in Boucherville, where the owners wanted to:
- Efficiently heat two independent floors
- Reduce their reliance on electric baseboard heaters
- Maintain constant comfort even during cold spells
Result: a significant reduction in energy consumption and stable temperature even during a period of -27°C.
Advanced energy efficiency
This model offers high performance:
- SEER2: 22+ (depending on configuration)
- High HSPF2
- COP of 1.93 at -8°C (according to provided data)
These indicators translate concretely into:
- Significant energy savings
- Improved efficiency in continuous heating
- Eligibility for subsidy programs
Heat Xtreme PRO Technology: Designed for the Canadian Climate
Operation down to -35°C
Unlike many standard systems, this heat pump continues to provide efficient heating at very low temperatures. This means:
- Less reliance on backup systems
- Constant thermal comfort
- Better long-term profitability
According to the brochure, the system operates within a range of:
- Air conditioning: -30°C to 50°C
- Heating: -35°C to 30°C
Intelligent defrosting and restart
In our installations in Laval and Repentigny, we observe that:
- Automatic defrosting reduces performance losses
- Automatic restart protects the system during power outages
These technical details make a significant difference in winter.
Multi-zone Configuration: Maximum Flexibility
2 independent zones
This system allows connecting two indoor units, with individual control:
- Independent temperature per room
- Optimization of energy consumption
- Personalized comfort
Possibility of expansion up to 4 zones
The DIRM-36HXPRO28-4Z outdoor unit allows for future expansion:
- Up to 4 zones maximum
- Ideal for scalable projects
In a project in Montreal (Rosemont), we initially installed this system with 2 zones, with preparation for a 3rd zone in the future. This strategy reduces short-term costs while maintaining flexibility.
Air Quality and Advanced Indoor Comfort
Intelligent air management
Compatible wall units offer:
- Vertical and horizontal automatic louvers
- Uniform air distribution
- Elimination of cold zones
The louvers also have a position memory, improving daily comfort.
Integrated advanced functions
Among the important features:
- Humidity sensor
- Motion sensor
- Energy-saving mode
- Turbo mode
- "Follow me" function (optimization based on remote control position)
These options are particularly useful in modern open-plan homes.
AirGreen Installation: What Makes the Difference
An installation adapted to each building
At AirGreen, we never perform standardized installations without analysis. For this type of heat pump, we evaluate:
- Room distribution
- Actual thermal load
- Optimal unit positioning
- Piping length (important for performance)
Concrete example on the North Shore
In a house in Blainville, we:
- Installed a 12,000 BTU unit in the living room
- Installed an 18,000 BTU unit upstairs
- Optimized piping to minimize losses
Result:
- Better heat distribution
- Noise reduction
- Maximum system efficiency
Subsidies and Return on Investment
LogisVert subsidy
This model is eligible for a subsidy of:
- $3,960 (updated November 26, 2025)
This significantly reduces the acquisition cost.
Observed real savings
For several clients:
- 30% to 50% reduction in heating costs
- Payback in a few years
- Increase in property value

Common Mistakes to Avoid
1. Undersizing indoor units
An incorrect calculation can lead to:
- Poor performance
- Overconsumption
- Premature wear
2. Incorrect multi-zone configuration
The brochure clearly states that:
- The total capacity of indoor units must adhere to a specific ratio
Incorrect sizing reduces overall performance.

We have often corrected installations where:
- Units were poorly positioned
- Refrigerant lines were too long
- Drainage was poorly designed
Result: loss of efficiency and recurring problems.

What people ask us about multi-zone systems.
Can I heat one room and cool another at the same time?
No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.
What happens when every room calls for heat?
They share the outdoor unit’s capacity: 33,000 BTU/h at −8 °C, 36,000 at −15 °C.
How many heads can I connect?
Up to 4 on this outdoor unit. This product is configured for 2 heads.
How much is the LogisVert grant?
$3,960 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.
Is it ENERGY STAR certified?
Yes, cold climate, ID 3996075. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −35 °C.
Is it noisy?
Indoors, the reference head goes down to 28 dB(A). Outdoors, 63 dB(A): we place the unit away from bedroom windows.
Why a multi-zone instead of several wall units?
One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.
What does the warranty cover?
Our sheet lists 10 years on the compressor and 10 years on parts; labour is not included by the manufacturer. AirGreen extended warranty: possible.
A multi-zone system is planned room by room. At your home.
We measure every room, draw the line route and choose the right head for each zone. The on-site estimate is free and the quote arrives within 24 h.
