Tap a part to learn more.
Outdoor unit
One compressor for the whole house. It supplies up to 5 heads and modulates from 13,000 to 45,000 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.

A High-Performance Multi-Zone Solution for Quebec's Climate Realities
At AirGreen, we observe a clear evolution in HVAC needs in Montreal, Laval, Longueuil, North Shore, and South Shore each year: properties are getting larger, comfort expectations are increasing, and above all, heating capacity in winter remains an absolute priority. It is precisely in this context that the DIRECT AIR HEAT XTREME PRO (-35°C) 5-zone heat pump stands out as a particularly suitable solution.
This 48,000 BTU multi-zone system can power up to five distinct areas with a single outdoor unit, while maintaining stable performance even at extreme temperatures as low as -35°C. This real winter heating capability truly changes the game for Quebec residences.
Why This Heat Pump Truly Stands Out in the Field
Heating Performance Down to -35°C
Unlike many systems that quickly lose efficiency below -15°C, this HEAT XTREME PRO series is designed to operate in rigorous climatic conditions. It offers:
- Nominal Capacity of 48,000 BTU
- Power maintained even at -15°C and -8°C
- Guaranteed operation down to -35°C
In practice, this means less reliance on auxiliary heating systems, thus real savings on energy costs in winter.
Recognized Energy Efficiency
This model is certified:
- ENERGY STAR® (Cold Climate)
- AHRI: 207743794
- SEER2: 21.5 (approximation depending on range)
- High-performance HSPF2 for seasonal heating
These certifications are not just marketing: they allow access to programs like LogisVert, with a subsidy of up to $4,320, a decisive factor for several homeowners in Montreal and Montérégie.
An Ideal Multi-Zone Flexibility for Modern Homes
Configuration of up to 5 Independent Zones
The system allows for the installation of up to 5 indoor units, each controlling a different room:
- Master bedroom
- Living room
- Basement
- Office
- Secondary room
This approach offers precise temperature control in each zone, avoiding the classic imbalances of centralized systems.
According to the manufacturer's combination rules, the total indoor capacity can vary between 66% and 133% of the outdoor capacity, ensuring flexible adaptation depending on the actual building configuration.
Compatible Indoor Unit Types
One of the major advantages of this series is its compatibility with several types of units:
- Wall-mounted (most popular)
- Consoles
- 4-way ceiling cassettes
- Ducted units (conduits)
- Floor/ceiling
This versatility is essential for projects in Montreal where architectural constraints vary greatly, especially in plexes, condos, and century-old houses.
AirGreen Feedback: Installation in Longueuil
During a recent project in Longueuil, we installed this system in a two-story house with a finished basement. The client wanted to:
- Eliminate electric baseboard heaters
- Control each floor independently
- Maintain constant comfort in winter
Challenges Encountered
- Piping passage in an existing structure
- Managing outdoor noise near close neighbors
- Optimizing conduit lengths
Result
- Installation of 5 wall-mounted units (6k, 9k, and 12k BTU combined)
- Significant reduction in heating costs
- Uniform comfort throughout the house
This type of configuration perfectly matches the capabilities of the DIRM-48HXPRO28-5Z model.

HVAC Installation: What Customers Absolutely Need to Understand
Sizing and Unit Combination
A common error observed in the market is the oversizing or undersizing of zones.
At AirGreen, we analyze:
- The actual area of each room
- Building insulation
- Solar exposure
- The use of each space
This helps avoid problems such as:
- Short cycling
- Poor dehumidification
- Excessive energy consumption
Piping Length and Technical Constraints
According to the manufacturer:
- Max total length: up to 80 meters
- Level difference: up to 25 meters
These parameters are essential for multi-story homes or those with finished basements.
Maintenance and Durability: An Often Overlooked Aspect
Even a high-end system like this requires regular HVAC maintenance.
AirGreen Recommendations
- Filter cleaning every 3 months
- Complete annual inspection
- Refrigerant level check
- Coil cleaning
Neglected maintenance can reduce efficiency by up to 25% and shorten equipment lifespan.

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: 36,000 BTU/h at −8 °C, 45,000 at −15 °C.
How many heads can I connect?
Up to 5 on this outdoor unit. This product is configured for 5 heads.
How much is the LogisVert grant?
$4,320 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 2473685. 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, 65 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. 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.
