“James S. is very detailed and hardworking HVAC Technician! He is very knowledgeable, professional, and patient. He answered all our questions and took pictures of our concerns and before and after his job. He was here working late last Wednesday before Thanksgiving but we have to have him do additional work today as he found more damaged ducts that the previous technician missed to address. So we decided to get James S. to do the whole ductwork repair and install. He is young but his work ethic is commendable! He is very courteous as well!”

“Called the technician out, he not only fixed the problem but showed me what the problem was and explained how the system works and why the problem kept it from functioning as it should. He signed us up for the service to clean and inspect the unit every year. Well worth the money because of the difference in the power bill. Thank you for everything you did and explaining everything to me. Great job and great service.”
