We had a new water heater installed. I was thoroughly pleased with the work. They had to remove our basement door to get the old heater out and new heater down a very narrow space. They did so with no scratches or scuffs to the walls. They were professional throughout the installment. After the installation was complete Jon B explained what he did and how the unit worked. I was most impressed that a supervisor arrived to inspect the work. We will definitely use them again for all other heating and cooling needs.
