"Bill was willing to install a heat pump system that I purchased, even though his default was Bosch. His son and helper did the install over two days. It was getting late when they finished and the unit worked, although it whistled. I let Bill McGinley know but couldn't get them to come out to resolve the problem for over a week. Bill figured out that air was being sucked in between the top bottom front panels on the ACIQ central unit and did a workaround -- taping over it. The manufacturer ACIQ was no help in acknowledging that there was a problem with their product. I made a mistake paying on the basis of the quote rather then requiring an invoice. When I tried to apply for the NHSaves rebate, they wanted an invoice. Bill was not very responsive in sending me the invoice. He did when I told him NHSaves would be contacting him. But he was very accommodating in doing the work i wanted done instead of doing what he was used to doing."

"All I needed was a replacement for a broken, rusted toilet flange that was set in cast iron. The technician was very professional, and the quality of the work was excellent—I could never have done it myself. I gave 4 stars instead of 5 only because of the cost ($650). To be fair, I didn’t get any other estimates, but it did seem a bit expensive for a job that took only one hour."
