LENNOX MMDD Ducted Air Conditioner | 12000 BTU | Parts by Samsung

A highly discreet and efficient HVAC solution for residential and commercial spaces

In the world of modern HVAC solutions, discretion, efficiency and reliability have become priorities for both residential and commercial owners. It is precisely with this in mind that the LENNOX MMDD 12000 BTU Ducted Air Conditioner , designed with parts by Samsung and operating with R-32 refrigerant , stands out as an essential reference. At AirGreen, we have had the opportunity to install it in various projects in Montreal , Laval , Longueuil , as well as on the North Shore and the South Shore , with remarkably positive results.

Compact, quiet and efficient design

The LENNOX MMDD 12000 BTU is distinguished first by its medium static pressure ducted design , designed for environments requiring discreet integration . Thanks to its compact dimensions (35.5 x 17.38 x 7.88 inches), it fits easily between the suspended ceiling and the structural slab, while ensuring uniform air distribution in the rooms.

Its inverter technology coupled with R-32 refrigerant allows it to achieve superior energy performance , while reducing the environmental impact compared to older models using R-410A. It boasts an impressive noise level of only 27 to 34 dB(A) , thus offering optimal acoustic comfort - a decisive criterion for offices, shops and luxury residences.

Technical characteristics and innovation at the service of comfort

The MMDD air conditioner incorporates a series of advanced features designed to maximize the comfort of its users while simplifying its maintenance:

• Preheat function : Prevents cold air from blowing in heating mode.

• Built-in drainage pump with 27.5" lift , ideal for complex installations.

• Three fan speeds to adapt the airflow according to needs.

• Automatic restart after power failure.

• Integrated LED reading panel displays operating status and service codes.

Smart connectivity is also on the agenda thanks to compatibility with Samsung's SmartThings app, allowing for complete remote management: temperature settings, real-time consumption monitoring, alerts and diagnostics.

Exceptional installation flexibility

The LENNOX MMDD unit has been designed to adapt to different environments , whether residential or commercial. The duct connections can be oriented horizontally or vertically , which makes it easier for our technicians to carry out custom installations.

Flare connections (liquid and gas) ensure a quick and secure connection, while the included washable air filter contributes to better indoor air quality, an issue that has become central to all HVAC projects.

At AirGreen, we have installed this model in high-end condos in Griffintown , modern offices in Laval , as well as in family residences on the South Shore . In each case, our customers appreciated the visual discretion of the device , its silent operation , and above all the energy savings achieved .

Three controller options are available for the LENNOX MMDD:

• Wireless remote control rechargeable via USB-C or solar power.
