We just completed an install under Costco through MM Comfort Systems. We purchased a two-stage heat pump and gas furnace on the higher end. A conversion to propane fixtures was required as well as extensive sheet metal work. We also had our existing system cleaned. Jacob did an outstanding job with that.; friendly, professional and non-intrusive. Jesse was the lead installer with Randy assisting. Very nice men. The sheet metal work Jesse completed is impressive. It was complicated and they were here for two days. Really nice people. Mike, from Services, made the final adjustments for the furnace conversion and installed a higher end controller that closely matched the rest of the system. Very cheerful bright guy. Bob was the consultant who put it all together and made sure everything stayed on track. You want this man on your team. He engineered it all and explained everything in as much detail as I needed, helping me to make the best decisions. They all exceeded my expectations and I see this system lasting a very long time while keeping us comfortable year around.
