Mitsubishi's VRF systems are designed to provide the quietest possible operation for both indoor and outdoor environments.
Condensing units operate as low as 56 dB(A) and indoor units operate as low as 22 dB(A).
This is of great value in spaces that require minimal disruption like places of worship and education. The units are so quiet, you can even place them right under a window, in closets, on balconies or near rooftop amenities without worrying about noise interference.
