"We set the installation date months in advance and Jeff showed up on time and prepared. Finished the job ahead of schedule and at the price he quoted. His work is clean and very organized. Jeff left room for zone expansion with circulators and piping stubbed off with caps installed. His piping is second to none…. I highly recommend his services."
