"Hired JT to install central air into our home. He was very polite and professional throughout the installation. He took the time to explain the process completely. The install went flawlessly, the work area was cleaned up better than new. Any questions my wife had after the installation were answered promptly and professionally also. Highly recommended, will definitely use his company for any future projects."

"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."

"West Michigan Mechanical and Air Duct Cleaning was a referral from HomeAdvisor. I received a phone call promptly after requesting information on this service. I spoke with David who was very informative and professional. When the duct specialists arrived, they were very professional, informing me of everything they were going to do and how they would do it. It turns out that 30 years of dirt and debris had collected in my ducts (side note - I happen to be a clean freak), I had no idea they would be that disgusting! They actually take before/after photos of every vent cleaned so you can see the work that has been done. There was no mess, they were extremely kind and professional. Would absolutely recommend them and already have...best $300 I have ever spent!"

"Amazingly fast service. Quoted to fix my HVAC and replace my central air unit $1,000 below a competitor! I highly recommend"

"They year previously the installed air conditioner, new furnace, new duct work, new chimney liner and a new hot water heater. They were really good. I told them my budget and they worked with me on that. They didn't laugh at me when I try to figure out how to turn my hot water heater up."

"They've maintenanced my furnace before I required a new one and they've always maintenanced the new one since I got it replaced about 3 years ago. Very easy to work with. I think I've been using them since 2008."

"Terry Jones did a superb job, I really can't overstate that. With how old our house was Terry ran into a number of minor issues that other providers may either A) ignored or B) charged extra for each item. Not only did Terry take care of all these problems, he stuck to his original estimate of work quote. The work was top notch, very much "if it's worth doing, it's worth doing right." When we asked for work bids, Terry called us first thing and was there for the estimate in short order. He worked with us to get the Furnace and Water heater that suited our needs/want and quickly adjusted his quote for us. When he ran into unexpected delays with our project, he sacrificed his Saturday to make sure our furnace and water heater were properly installed. I would use his services again without hesitation, and you should, too."
