  • What can I say.  They were speedy and tidy.  Everything was as predicted.  They provided good and timely information as the install proceeded. The system, while not silent, makes very little noise, much less than the window units it replaced.

    We lived through 5 years in the home with window AC units and thought we couldn’t do central AC in our home.  Now we think it was the best money we ever spent on our home.

  • We needed an emergency repair to our HVAC unit in our condo. When we came home on Friday night, the unit had shut off. I called a few services and they were either already booked or didn’t offer weekend service if you weren’t already a customer. Sila called me back quickly. They were able to send someone out who was able to diagnose and fix the problem in about an hour. They were professional.

  • This company was absolutely fabulous; I wish every contractor had the same focus on quality and service. Every single person in the company I dealt with was very professional, courteous, respectful, and reliable. Their pricing was the lowest of all bids I received for exactly the same work and the same models of equipment to be installed. Work was completed quickly, and in accordance with the agreed schedule.

  • Team came promptly. Serviceman was very thorough and mindful of my house (used slippers to shield floor). Diagnosed problem and explained options and cause. THE FOLLOWING DAY Sila sent another serviceman to verify diagnosis. This is done to ensure you are getting the best advice. All in all, the service was prompt and correct.

  • This is the second time I’ve used these guys. Courteous, quick and knowledgeable. Also, called at 7:30 am and they were here at 9:30 am…..the heat is working again and will plan to call them in the spring for maintenance on the AC unit too.

  • The technician was very thorough, knowledgeable, efficient, and honest. We were very impressed with his work and assessment of our system. He was not pushy in trying to sell us a new unit, even though we know we will need one in a few years. I will definitely keep Sila on my list for when the time comes to invest that money.
