At AirGreen , we are committed to providing complete HVAC solutions that meet the requirements of performance, reliability, and comfort. The LENNOX MMDD | 9000 BTU | Parts Ducted Air Conditioner by Samsung perfectly illustrates this commitment, thanks to its discreet design and notable energy efficiency. Designed for homeowners who want to achieve a stable indoor temperature throughout the year, this ducted model blends harmoniously into the space, without compromising the interior design or the comfort of the occupants.

This unit stands out for its compact form factor , its 9,000 BTU cooling capacity, and its design based on high-quality Samsung parts. This synergy between Lennox and Samsung brings remarkable reliability as well as long-lasting performance. In the following paragraphs, we explain why this air conditioner meets the needs of many residents of Montreal , Laval , Longueuil , the North Shore and the South Shore , and how our AirGreen team masters the installation and maintenance of this system to ensure optimal comfort all year round.

Easy integration and proven performance
One of the main advantages of this ducted air conditioner is its ability to be completely hidden within the building structure. In fact, the LENNOX MMDD model is designed to be installed behind a suspended ceiling or in a technical space. This means that only the air diffusion and return grilles appear inside the rooms, providing a clean aesthetic. Thanks to its medium static pressure , this unit supports longer ducts, making it suitable for homes of different sizes and configurations.

For many homeowners in Montreal and its surrounding areas, the visual discretion of such a system is a key criterion. A recent condominium on the South Shore , for example, was able to benefit from this air conditioner, installed by our AirGreen technicians in a confined space near a suspended ceiling. Despite this invisible integration, the unit ensures a stable indoor temperature and minimal noise levels (between 26 and 33 dB(A) depending on the settings). Occupants immediately highlighted the appreciable silence and cooling performance, even during the hottest summer days.

Main technical characteristics

HVAC installation in Montreal and surrounding areas

For homeowners and commercial building owners in Montreal , Laval , Longueuil , on the North Shore and the South Shore , installing a ducted air conditioner requires recognized expertise. Ducts must be sized according to the average static pressure and the building's configuration. Our AirGreen team always begins with a free on-site estimate to determine the ideal duct layout, adequate power and optimal location of the indoor unit.

During a recent construction site in a duplex in Longueuil , we carefully planned the ductwork to serve two distinct zones (ground floor and upper floor). The occupants were looking for discreet comfort, and above all a system that could independently heat or cool each level. Although this model only offers a single treatment zone, we integrated internal zoning via motorized dampers. This approach allows fresh air to be directed into one or the other of the zones as needed, thus optimizing energy consumption and occupant comfort.

AirGreen Case Study: Reliability and Expertise

At AirGreen , we had the opportunity to install this LENNOX MMDD | 9000 BTU model in an 1100 sq. ft. condo in Laval . The owner wanted a discreet system to mainly cool the living room and master bedroom. Initially, he considered a traditional wall-mounted unit, but we recommended the ducted model to preserve the aesthetics of his cathedral ceiling.

• Step 1 – Evaluation : Our technicians assessed the volume of air to be treated, the ceiling height and the general configuration of the condo.

• Step 2 – Sizing and Design : We validated that 9,000 BTUs was ideal. Then, we developed a minimalist ductwork plan to distribute air to the main room and bedroom.

• Step 3 – Installation and Calibration : The indoor unit was fixed in a false ceiling, connected to the outdoor unit via 1/4 – 3/8 piping. We carried out a leak test and a meticulous vacuum draw .

• Step 4 – Commissioning : After the electrical connection and configuration of the wall thermostat, the customer was able to enjoy a perfectly tempered indoor environment. He was surprised by the low noise level and delighted by the absence of a visible wall box.

This case illustrates the advantages of a ducted unit: aesthetics, even air distribution and the unit's inconspicuousness. In addition, maintenance is simplified thanks to direct access to the interior panel for cleaning the removable filter.

Maintenance tips and mistakes to avoid

Regular maintenance of your ducted air conditioner is crucial to maintain its efficiency and extend its lifespan. At AirGreen , we recommend:

• Filter replacement or cleaning : Every three months or depending on the environment (dusty or not). A clogged filter reduces air quality and forces the system to operate more intensively.

• Condensate drain check : Ensure there are no blockages or leaks. Water accumulation can cause damage to the ceiling structure or electronic components.

• Seasonal inspection : Before and after the air conditioning season, a complete check by our technicians allows us to detect any anomalies (abnormal noises, excess energy consumption, gas loss).

Common mistakes to avoid include:

• Underestimating the necessary size : Choosing a ducted air conditioner with too few BTUs can result in excessive duty cycles, increasing your electricity bill. Conversely, choosing too high a power could lead to frequent on-off cycles, reducing comfort and system durability.

• Entrust the installation to a non-specialist : HVAC installation requires specific skills, especially when it comes to ducted systems. Incorrect positioning of the indoor unit, improper duct sizing, or faulty connections can lead to noise, performance, and reliability issues.

• Ignoring the need for scheduled maintenance : Even though this air conditioner is discreet and seems to operate smoothly, professional maintenance is still essential to maintain optimal efficiency.

Technical innovations and optional accessories

The LENNOX MMDD | 9000 BTU | Parts Ducted Air Conditioner by Samsung is compatible with a variety of wired and wireless controls .
