Introducing the new MPB and MLA Mini-Split Heat Pumps

Ideal for all types of homes and spaces

Lennox Mini Split Heat Pump

When new ductwork doesn’t work, mini-split heat pump systems do.

MPB/MLA heat pump systems are perfect for spaces like add-on rooms where installing or extending ductwork isn’t practical.

Easy to install, each system uses a compact indoor and outdoor unit connected through a small hole in the wall.

One outdoor unit can support up to five indoor comfort zones, creating a customized whole-home heating and cooling solution.

Designed with outstanding cold-climate capabilities, MLA heat pumps maintain 100% capacity at 0°F and can operate at temperatures as low as -22°F.
