A Reliable Multi-Zone Solution for Consistent Comfort in Montreal, Laval, and the South Shore
At AirGreen, we regularly install multi-zone systems to meet the real needs of residential and multi-unit properties in Montreal, Laval, Longueuil, the North Shore, and the South Shore. The DIRECT AIR DA25 (36000 BTU) 3-head heat pump stands out for its flexibility, stable performance down to -25°C, and its ability to power multiple rooms with a single outdoor compressor.
This type of system is particularly sought after by homeowners who want an efficient HVAC installation, without multiplying outdoor units, while maintaining precise temperature control in each zone.
Multi-Zone Performance and Energy Efficiency: A Strategic Combination
Power Adapted to Quebec Realities
With a cooling capacity of 36,000 BTU and heating performance down to -25°C, this heat pump meets Quebec's climatic requirements. Unlike many entry-level systems, it maintains useful power even during cold periods:
- Power at -8°C: 26,800 BTU
- Power at -15°C: 25,200 BTU
- COP at -8°C: 1.83 (measured real efficiency)
This means that even in winter, the heat pump continues to provide efficient heating without excessive reliance on a supplemental source.
Energy Efficiency and Operating Costs
The DA25 series offers interesting performance indices:
- SEER2: 23.9 (efficient cooling)
- HSPF2: 9.5 (seasonal heating)
- EER2: 11.7
According to the technical brochure, some models in this series can reach up to 23.5 SEER and 11.5 HSPF, which confirms its position as an energy-efficient solution suitable for modern residences.
In our projects in Boucherville and Laval, we have observed energy consumption reductions of up to 30% compared to traditional electric systems.
3-Zone Configuration: Maximum Flexibility for Your Home
An ideal solution for:
- Multi-story houses with distinct rooms
- Plexes or duplexes in Montreal
- Condos with multiple living areas
- Extensions or renovations without ducts
The triple-zone configuration allows powering up to 3 indoor units, with the possibility of expansion to a maximum of 4 zones.
Indoor Unit Compatibility
The system accepts several types of units:
- Wall-mounted (most popular)
- Floor consoles
- 4-way ceiling cassettes
- Ducted units
In a recent project in Longueuil, we installed:
- 1 x 18,000 BTU unit for the living room
- 1 x 12,000 BTU unit for the upstairs
- 1 x 9,000 BTU unit for the basement
Result: homogeneous distribution, without overheating or cold spots.
Integrated Technology and Features
Smart Comfort and Automation
The indoor units offer several advanced features:
- Automatic restart
- Intelligent defrost
- 24-hour programmable timer
- Energy-saving mode
- Turbo mode for rapid temperature increase
- "Follow Me" function (temperature based on remote control)
WiFi is available as an option, compatible with smart home systems (Google, Alexa).
Advanced Air Management
An often underestimated point: airflow management.
- Automatic vertical vanes
- Automatic horizontal vanes
- Vane position memory
- Integrated humidity sensor
- Biofilter to improve air quality
In several installations in Montreal, this feature has corrected common problems of poor air circulation in enclosed rooms.
HVAC Installation: AirGreen Field Expertise
What We Observe in the Field
A common mistake when installing multi-zone systems is the incorrect sizing of indoor units.
The technical rule from the documentation:
- Total indoor capacity must be between 66% and 133% of the outdoor capacity
An incorrect calculation leads to:
- Loss of heating performance
- Imbalance between rooms
- Premature compressor wear
At AirGreen, every project includes:
- Complete thermal analysis
- Precise load calculation
- Optimized unit selection
Real Example – Laval
A client initially chose 3 units of 12,000 BTU (36,000 total). Potential result: overload.
We adjusted:
- 18,000 + 12,000 + 9,000 = 39,000 BTU (within acceptable range)
Result:
- Better stability
- Fewer short cycles
- Uniform comfort
Sound Level and Acoustic Comfort
- Indoor: 22.5 to 36 dB(A) (very quiet)
- Outdoor: 63 dB(A)
In a project in Rosemont, the client wanted a discreet outdoor unit. We installed a wall bracket with dampeners:
- Reduction of vibrations
- No perceptible noise indoors
Dimensions and Installation Constraints
Outdoor Unit
- Dimensions: 37.24 × 16.14 × 31.89 inches
- Possible installation:
- Wall-mounted
- Ground with anti-vibration base
Piping
- Maximum length: up to 80 m total (depending on configuration)
- Level difference: up to 25 m
This allows for great flexibility, even for complex properties on the North Shore.
Refrigerant and Environmental Impact
- Gas: R-410A
Although this refrigerant is still widely used, we always inform our customers that newer alternatives like R-32 exist. However, R-410A remains reliable and effective for this type of application.
Warranty and Reliability
- Compressor: 5 years
- Parts: 5 years
- Labor: 0 year (extension possible)
At AirGreen, we strongly recommend adding an extended labor warranty, especially for multi-zone systems.
Subsidies and Return on Investment
- LogisVert Grant: $1340
Even if this model is not Energy Star Cold Climate rated, it remains eligible for certain aids.
In several cases in Longueuil and Brossard, the return on investment is achieved in 4 to 6 years, thanks to:
- Reduced heating costs
- Replacement of energy-intensive electric baseboards
