"It was wonderful working with Chris/ Nextgen today. He did a great job explaining everything I need to do with my unit, what to expect, and all the benefits I can get from it. I really appreciate the time he took to answer my questions and make sure I understood everything. I just want to say thank you, Chris, for all your help! I look forward to a great installation! I’m scheduled for tomorrow"

"I had Pro Tech repair two pieces of wooden furniture. They were very cordial and professional. They worked very hard when they were here and treated my furniture very carefully. Both pieces look MUCH better than before!! Although this is the only service I used them for, I believe their specialty is HVAC and I would try them for that if I had the need."

"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."
