We had a new HVAC installed by defunct Rocky Mountain Air, the Freon is always gone every year. After calling Chris last year, he came in and checked it out last year and fixed it. This year we had the same problem, Chris came out again on call. It seems that he found the leaked and put a solution to it. Also, he honored the warranty and charged nothing for this year’s work. Even we had up and downs, their positive attitude deserved a five star.
