A Discreet and High-Performance Solution for Uniform Comfort Throughout the Home
At AirGreen, we regularly install ducted heat pump systems for clients seeking consistent comfort without compromising the aesthetics of their space. The DIRECT AIR DA25 18000 BTU model particularly stands out in this segment due to its ability to offer centralized air distribution that is quiet and efficient, even in the demanding climatic conditions of Montreal, Laval, Longueuil, North Shore, and South Shore.
Unlike visible wall-mounted units, this system integrates discreetly into ceilings or technical spaces, making it a strategic choice for modern residences, high-end renovations, and certain commercial projects.
Performance and Technical Specifications: A Concrete Balance Between Power and Efficiency
The DIRM-18HP-DUH (indoor) model combined with the DIRM-18DA25-1Z outdoor unit offers an 18,000 BTU capacity, perfectly suited for medium-sized residential spaces or specific areas requiring constant air conditioning and heating.
Key Features to Remember:
- Cooling Capacity: 18,000 BTU
- Heating Capacity down to -25°C
- SEER2: 20.5 (according to the brochure, up to 23.5 SEER for the series)
- HSPF2: up to 11.5
- COP at -8°C: 12.43
- Refrigerant: R-410A
- Indoor Sound Level: 38 to 43 dB(A)
- Outdoor Sound Level: 58 dB(A)
- Voltage: 220V
- Piping: 1/4 – 1/2 in
These figures demonstrate a well-balanced system: powerful enough to face Quebec winters while maintaining interesting energy efficiency for milder seasons.
Why choose a horizontal ducted system over a wall-mounted one?
In our field experience in Montreal and Montérégie, many clients opt for this type of system after comparing available options.
Concrete advantages observed:
1. Uniform Air Distribution
Unlike wall-mounted units, air is diffused through ducts, eliminating cold or hot spots in a room.
2. Invisible Aesthetics
No apparent wall unit: ideal for modern designs or high-end renovations.
3. Reduced Perceived Noise
With a well-designed installation, noise is distributed and attenuated, significantly improving comfort.
4. Installation Flexibility
Thanks to its compact horizontal configuration (34.65 × 28.53 × 8.27 inches), this unit easily integrates into suspended ceilings or confined spaces.
AirGreen Experience Feedback: Installation in Boucherville
During a recent project in Boucherville (South Shore), a client wanted to replace two visible wall-mounted units in an open-concept space with a more discreet solution.
Challenges encountered:
- Limited ceiling height
- Need to maintain uniform air circulation between living room and kitchen
- Strict aesthetic constraints
Proposed solution:
Installation of a DIRECT AIR DA25 18000 BTU ducted heat pump, with:
- Optimized duct network
- Strategically positioned diffusion grilles
- Adjustment of external static pressure (up to 0.40 inches of water column according to the technical sheet)
Result:
- Homogeneous temperature throughout the area
- No perceptible noise in living spaces
- High customer satisfaction after the first winter season
Smart Features and Daily Comfort
This model is not limited to raw performance. It integrates several features that facilitate use and improve comfort:
Included or available features:
- Automatic restart after power failure
- Automatic defrost (crucial for Quebec winters)
- Programmable 24-hour timer
- Optional WiFi, compatible with smart systems
- Variable static pressure control to adjust air distribution
- Integrated drain pump
These elements are particularly important in ducted installations, where system balance depends on several technical parameters.
What clients absolutely need to understand before installation
In our practice, several common mistakes occur when clients consider a ducted heat pump:
1. Underestimating the importance of duct design
A good unit poorly distributed yields poor results. At AirGreen, we always dimension the duct network based on:
- airflow (CFM)
- pressure losses
- the actual building configuration
2. Neglecting static pressure
This model offers an external static pressure range of up to 0.40. Incorrect configuration can lead to:
- excessive noise
- energy inefficiency
- poorly served areas
3. Installing without planning for maintenance
Even though these systems are discreet, they require:
- access to filters
- periodic inspection
- drain cleaning
Energy Efficiency and Available Subsidies
The DIRECT AIR DA25 model is ENERGY STAR® certified, making it eligible for certain subsidies like the LogisVert program.
Concrete example:
- Current subsidy: $630
- Direct reduction of initial cost
- Accelerated return on investment through energy savings
Even if this model is not classified as “Cold Climate Energy Star,” it remains efficient down to -25°C, which covers most residential needs in the Montreal region.
Maintenance and Durability: What We See in the Field
With the installations we have been monitoring for several years, we observe that DIRECT AIR systems offer:
- Good performance stability over time
- Reliable components when properly installed
- Relatively simple maintenance
AirGreen Recommendations:
- Filter cleaning every 3 months
