  • Sila is very accommodating with making appointments that match your time needs. The technicians are very knowledgeable, seem very through with inspecting the equipment and will show you parts that need replacing and why.

  • We found Sila on the internet under “ductless systems” search. The idea of “ductless’ came after years trying to make our attic-installed HVAC system more effective. Appointment with Sila in Philadelphia office was easy to make. The rep ( Mr. Smutko) showed up on time. He was attentive, courteous and quickly evaluated our problem. He explained our system problems well, using diagrams and pointing out problem areas. Spent with us all the time needed. It was a pleasant surprise — he is clearly an asset for Sila. We wish we had called Sila earlier to better understand the way our attic-installed HVAC system works and where the problem areas were. The most knowledgeable rep we talked to so far.

  • I found Sila on Angie’s List. They have been providing routine service for about 2 years now. They are very good. This fall when I woke up to no heat, but still had to go to work, they worked with me to meet me after work so I did not have to leave too early. They have always been on time. I will continue to use them. They are more honest then other companies.
