  • When I was starting to have problems with my furnace. I tried two other companies, before I tried Sila. Sila’s service was impeccable, they showed up the same day, the technician knew exactly what to do, was courteous, and took the time to explain to me (in layman’s terms) what was happening and why, and how to fix the problem. They were neat, fast and efficient. Sila wasn’t the cheapest of the three companies, but in hindsight, I would have saved myself time, energy and money, had I used them the first time around.

  • Craig showed up at 8 a.m.as promised to do an Angie’s Lists Big Deal and flush the hot water heater. He was friendly, fast, and gave me good suggestions for the future of that water heater. Quite impressed!

  • Sila is the best! I trust no other company with my home. Sila is the type of company that makes you think, “I wish every business I dealt with was like Sila.” They installed and service my heater, ac, and generator, did my dad’s new geothermal, too. He loves there efficiency and knowledge. I love their service, punctuality, and cleanliness. Their prices are competitive, and worth the cost given their incredible business integrity. Chris is my favorite service provider. I always ask for him. He is one of many reasons Sila is the best!

  • 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.

  • 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.
