"Called Josh on a Saturday morning to report a problem with our heat pump by noon he was here and had identified the problem. We are very happy with this company as they do not use a 1000% markup on parts like some HVAC companies in the area seem to charge. With Air Adviser you get Honest service at an Honest price."

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."
