"The Project is still in the begining stages, but Rubin has been very helpful with information on my options and best system to install and we have signed a contract and are just waiting for the order to arrive and installation to begin. At this stage I would give Rubin very high marks."

"One Hour has been my HVAC supplier for more than a decade, and I have never had a reason to consider any other firm. This week Justin L. and Steve came to install improvements. They were professional, courteous, and took the time to explain to me just what they were doing, and to answer my questions. On a scale of one to ten they were both elevens. I'd give them six stars if I could. You can trust One Hour to do it right."
