  • The installation went very well. The installers were very professional and left no mess whatsoever. The unit works great. I thought the price of the electrical work was on the high end. Sila sales rep made it clear that I could get someone else to perform the electrical work. To avoid the hassle of coordination, I elected to have all the work done by Sila Heating and Air Conditioning. They were able to run the wire in the attic, and it was a little tricky getting it to the soffit on the roof eaves. The electric wire and line-set pipes were concealed inside a piece of aluminum downspout.

  • They came out and did the inspection; I bought a comprehensive insurance policy in case anything goes wrong with the A/C or furnace in the future. They called us a couple of times, once because the repairman was sick once because of the weather. I was pleased they were reachable and attentive. I’m sure if something goes wrong I can call them out quickly because they are close to resolve the problem.

  • The Sila team did a very thorough job and consulted with me along the way. In other words the team let me know what they were going to do before they did it and got my approval. The Sila team has also been great in working with my changing schedule.

  • Can’t say enough good things about these guys. We had no heat and logged an emergency call, since we have a 2-year old in the house. Al called back quickly – at 10:00 at night – and spent likely a total of half an hour to 45 minutes on the phone, combined with countless texts, trying to help us troubleshoot the problem so we wouldn’t have to pay extra for an overnight call.

    It turned out that we really did need a service call the next morning – our boiler is ancient and weird and, as it turned out, a serious challenge to work on. As a matter of fact, a friend who does this for a living took one look at it and told me we’d need a new one. Not Al. Nope. He was a freaking ninja. He pulled that thing apart, piece by piece, figuring our 50+ year old system out from scratch. Through the whole frustrating process, he was thoughtful about his approach, extremely respectful, and seemed to not mind the million and one questions. Thanks to Al, I now have a toasty-warm house AND a really solid understanding of how my boiler works.

  • We are very pleased with the work performed by Sila.

    From our initial conversations and throughout all the subsequent stages of our project it was clear we were in good hands. We had many considerations to take into account and Bryan helped us navigate them without ever pushing us one way or the other, we always felt we had as much control as we wanted.
