American Standard MSZ-EF Designer Heat Pumps.

Quiet Operation

Although the MSZ-EF Designer Heat Pumps are installed directly into rooms in your home, their whisper-quiet operation makes it so you barely know they’re operating. These systems can easily be used in noise-sensitive residential and work places.

Breathe Easier

This ductless system is equipped with washable, anti-allergen filters to help improve your home indoor air quality. Filters help trap dust, bacteria, and other particles floating in the air you breathe.

Advanced Heating Technology

Rest easy on cold days with this ductless system. Thanks to hyper-heating inverter® heat pump technology, these systems can provide warmth in extreme climates, down to -13°F.

Easy Installation

Ductless systems are directly installed in the room or space they’re intended to heat or cool, which makes installation a breeze. Without the presence of ducts, vents, and other components, ductless systems can typically be installed by an HVAC professional in a short amount of time, without disrupting your living environment.
