“A+, from beginning to end, Paul, the manager, was highly informative and clearly answered all questions I had regarding replacement of a leaking 13 year old water heater for the 22 unit apartment building I manage. He also offered the best pricing of the 4 or 5 businesses I contacted. Loni, the installer, was solid as well, completing the installation in exactly the amount of time estimated. Friendly, informative, skilled… I would not hesitate to recommend this company.”~ David R
