"Great! Gammons was quick to provide a quote at a fair price. I was able to review and approve the quote via a link in an email. Gammons scheduled the work right away and swapped out the tank in an afternoon. Everything was neat and very professionally done. We’re very happy with the work and function of the new unit."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"Zach and Macky were great! I called the day before, received a call back that night and they were here first thing the next morning- just about a 12 hour service time! Being a single, female, first time homeowner, I was unsure what to expect and they were both great at explaining the jobs and each piece going into the repair. Highly recommend and will be using them again!"
