"I felt that the extra fee was excessive. Other Carrier installers contacted me and agreed to perform the repair for the amount Carrier reimbursed them, with no extra cost to me."

"Started with brand of furnace, asked what I had done to attempt to fix the problem.  (It was then that I realized how 'ignorant' I really am.)  She recommended I check the circuit breaker.  Never occurred to me to check since I had electricity on the first and second floors.  Got a bit suspicious when the stairwell light to the basement didn't come on.  So, I got a flashlight and checked the breaker.  Turned it off and then on again.  And ... low and behold, the furnace came on.  (guess who was Very Embarrassed)   We went on to chat a bit to make sure it was going to stay on.  She was very pleasant and understanding.  I inquired about replacing my furnace humidifier and she gave me information as well as cost.  A bit pricey, but I'm fairly confident I will call back and schedule to have them install one.

"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."
