  • I was amazed by their attention to detail and cleanliness. They were professional and courteous. They’ve inspected and repaired my water heater and heater with focused professionalism. I’ve maintained a service contract for several years. I’ve had many different technicians performing various duties in and outside my home without issue. I will retain their heating and cooling services.

  • Ever since we decided to go with Sila for our Heating and Air Conditioning solution several years ago, our family has been impressed and our expectations exceeded. From the analysis of where our house was losing heat to the installation of the insulation and geothermal, everyone we’ve had in our home or spoken to on the phone has been professional, friendly and has gone out of their way to make sure we were satisfied. The timely calls and flexibility for our yearly maintenance and the immediate attention and response to minor incidents we’ve had (our fault for not changing the filter!) have made our continued interactions a pleasure and left us with a confident security that Sila is as committed to customer service as they are quality products. We already highly recommend Sila to our family and friends, but it’s about time I leave a review!

  • I have used Sila twice now. First time, AC was not working because wire had been disconnected from outside compressor unit. They looked at the system and were able to diagnose why the system was not powering on 100%, fixed it, and added additional line so hopefully it won’t happen again. At no extra cost.
    Second time, and just a week later, I noticed the condensate line began to quickly drip. It was clogged. They came out same day and quickly unclogged the line. The service charge has been very reasonable especially given the same day service. Prompt, knowledgeable techs. I will definitely continue to use this company when they provide this level of service and reasonable rates. Highly recommended.

  • Wow! Sila saved me so much money and turned my heater into an instant hot box with hot air blowing with force. I thought I needed a new system and the technician came in and cleaned and put new filter in and BAM it was instantly 75 in our house! Thanks Sila for saving our family from freezing.
