    First technician (maybe Dave?) diagnosed heating problem, shut off the unwanted heat in front rooms (because it is summer), and provided options for full repair, but we did not have time for repair that day. Following week, second technician (Guy) came for annual AC checkup, and was also able to recheck the heating problem and review options. We discussed plans to fix the heating problem along with annual heating checkup in September, and revisit the AC next year. Both technicians seemed knowledgeable and professional

    They were excellent and even replaced all the duct work in my attic, and built a cement slab and put an outside unit on it as well. They did all the gravel and cement and it took about 2 or 3 days.I would highly recommend them to anyone and will continue to use them as well. .

    Great work and very communicative throughout the whole process. Pricing feels a bit more expensive than I would've expected but the quality of the work makes it more than worth it. They even helped patch up holes and some damage on my very old floorboards for free when refinishing.

    Good, friendly crew, installed system in one day, then final tune up was done two days later with another technician who explained operation. Very professional.

    John G from Sila was a true professional. He called to say that he could do the service call on Friday evening instead of Saturday citing concern that we had no heat and the temps were going to dip that evening. He quickly identified the problem, expedited the parts delivery and even serviced our 2nd furnace which we did not realize was having issues until he inspected it while on site. He stayed late on a Friday evening to get the job done. John G and Sila provided top notch service and I highly recommend

    Fantastic! Brian MacFarland was able to diagnose the problem promptly. He had all the parts with him so our heater was up and running very shortly after we made the call. We will continue to use Sila for our a/c and heating needs.

    John G. did an excellent job evaluating the functioning of our boiler and performing annual maintenance for it. It was his second time taking care of the boiler for us. He quickly answered the minor questions that I had, and he advised what would be cost-effective in addressing the issues that I raised. In both the instances in which John G. has serviced our heating system, I found him to be knowledgeable, courteous, and focused on saving us money, whether on heating costs or future upgrades

    Unprofessional and inexperienced. They abandoned us in the middle of a job and ignored us & our insurance agent for a month after jackhammering a hole in the floor of our house. Made all kinds of promises, got in over their heads, and then bailed. Absolute disaster to deal with
