  • 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.

  • I had Sila put in a new state of the art climate control system in my new house and a boiler / hot water heater at another property. Both projects were done on time without any problems. It was a large and complex project and I was very impressed with how they came through.

  • 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!

    Bob D., Malden, MA
  • We had a 26 year relationship with a heating and A/C service group that serviced our system twice a year. When we sensed the service quality was beginning to decline, we found Sila from Angie’s list. They met with us and reviewed the entire system and proposed a service contract that was reasonably priced and comprehensive. Excellent service.

  • Central air conditioning was installed. They used flexible tubing instead of traditional duct work, which is a better approach for an older home. The team worked hard and did an excellent job. They were considerate, professional and cleaned up after themselves.
