Mitsubishi Electric Ductless Systems

Room air conditioners make your home's individual rooms or other small spaces more comfortable. Remember, just like whole-home systems, the higher the SEER and HSPF ratings, the more efficient they will be.

We offer a variety of window room air conditioners, through-the-wall packaged terminal air conditioners (PTAC) and ductless heating and cooling systems to meet any individual room's needs.
