JTAC is the bomb. Jack got to me first thing in the morning, diagnosed the problem right away and got me up and running. Then, when different problem occurred on the weekend, He was here, and got me cool. 100% will be calling him again and highly recommend him.

I am a first time user with Jack. He was recommended to me by a neighbor/friend who has worked with Jack on other projects. I highly recommend him for his professionalism and OUTSTANDING workmanship. His prices were fair and reasonable. He came out on a Sunday in 100 degree heat to be of assistance. He had the system working within 36 hours. I can’ t ask for more than that. I am now a long time customer.

Jack came to service our AC unit yesterday. He squeezed us into his schedule with no other availability this week. He communicated timing, and when he arrived, he correctly diagnosed the issue in less than 15 minutes. We would recommend Jack’s business for HVAC repairs.

I used Jack for the first time for tuning my AC units, and was impressed with his commitment to customers and honesty. He stated no task is a small task, and his willingness to address any task was impressive. He is knowledgeable and went beyond by fixing one of the ducts that came off the unit. I found my AC mechanic for future repairs.

Jack is very professional and on time. This was the first time to hire his services and was very impressed with the way he shares all the information about what he sees that needs to be done and his plan to completion. If you don’t already have a good a/c contact, Jack should be your “a/c guy”.

Jack has been replacing, repairing, and maintaining my 3 systems for almost 2 decades. I wouldn’t trust my systems to anyone else.

Jack has been providing excellent service for our 2 home HVAC systems for 10+ years. He is professional, competent and punctual. Last year he replaced a 30 year old furnace in the attic at a competitive price. We will continue to utilize his services.

I had a great experience with JTAC service. Jack was professional, thorough, and easy to work with. He took the time to check the system, answer my questions, and explain things in a way that was very helpful. I really appreciated the honest, straightforward service and the peace of mind that came from having everything looked over carefully. It’s hard to find dependable service, and this was exactly the kind of experience you hope for. Highly recommend.
