  • 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.
    Sincerely, Z. Dodds

  • 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!

  • 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.

  • Just moved out from California to NYC, so I know very little about the gas/steam heating system in my house. Eric from Sila came out today and not only fixed my problem quickly but gave me a much needed over view of how the system works so that I can feel confident at pinpointing any problem in the future. It seems that they also have an array of cooling systems as well so I will definitely be going to them for that in the future. Well done Sila!!

  • 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!
