"Sila installed a new Lennox HVAC system 2 years ago and when there was a leak today they showed up within hours! Not like some places that would have many excuses and complain about Fri being too busy. Their Tech Calverton is a special tech, knowledgeable, polite and willing to go the extra mile. Not only did he fix the leaking problem he took his time to adjust dampers to ensure all rooms are toasty! This has always been a problem for us and not fixed until now. It takes a patient problem solving tech to make a happy customer! A special thanks to the service manager ,Doug Bines , who always seems to help when needed."

"We are extremely satisfied with the experience we had with Dario. Tony gave us a great estimate for a complicated job. He also gave us his honest advice about what to do and not to do. Glad we listened to him. He spent the time to figure out how to make something work even though it didn't look likely. The team was professional and friendly. We will definitely call them back for our future HVAC projects."
