The recent change from Mitsubishi to the R454b refrigerant has allowed us to install the first of its kind right here in Bozeman, MT. for a customer who knows what to expect out of a quiet and efficient dual fuel system. This change has also boosted efficiency, capacity at low temperatures, capacity at high elevations, etc. There's never been a better time for this technology and a company who has committed to learning the ropes of these high tech systems.”
