"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."

"After getting a really late (several days) or no response from two other plumbers, I contacted Griswold plumbing after finding them here. Jeremy called me back immediately, listened to my concerns and scheduled me for two days later. The other plumber that actually returned my call needed a week after missing the first appointment. Jeremy showed up and identified the issues with my hot water and quoted me a very fair price for the amount of work he ended up having to do on my neglected plumbing. He was friendly, quick, honest, and professional. He had everything completed within a reasonable time and my hot water never worked so good. I decided to go with him again for another project I need help with and I will keep Griswold Plumbing in mind for my next home. The reviews really show what great service these guys provide!"

"The service was fantastic. These guys are the best. They were very thorough and gave good suggestions on how to improve the efficiency. They sealed things up and caulked and put in weather stripping. This particular crew has an inspector that checks the work. The inspector said I really enjoy checking this companies work as he said they are very efficient and they do great work. They were very nice and knowledgeable to work with. This was part of a program in Connecticut where they will replace up to 40 light bulbs with compact florescent bulbs. They will change out light fixtures with LED lights and the cost was far better than I could have gotten myself. They run a test before the work is started and then they do a test afterwards to show how much more efficient your home is. They give a report showing how efficient your home is and making other suggestions. They also give you discounts on making your home more efficient within a certain amount of time from the report."

"I HAD TO HAVE MY AIR DUCTS CLEANED. THE PRICE WAS REASONABLE. THEY GOT RIGHT TO WORK AND FINISHED IN A REASONABLE AMOUNT OF TIME. I WOULD CHOOSE THIS COMPANY AGAIN FOR THEIR SERVICES."
