"I had to remind them to clean the dryer vent
a lot of tiime was spent trying to convince me to buy a fancy UV system for cleaning my HVAC, which I didn't want
I just wanted them to perform and service and leave -- I didn't sign up for a sales pitch

"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."

"My friends had installed a new HVAC system and they told me that the system improved the monthly utilities bills and the house is always warm. I contacted the company that made the installation and I spoke to Ezra. Ezra provide me with some basic information about them and about the system that they installed at my friend’s house and he asked me to pass by and look at my house in order to determine what will be the best system for my house. Ezra arrived to my house and checked the existing system and he explained to me the differences between that one to the new one. I decided to hire them and to go for the system. Before the installation, Ezra came over and did a special test that took close to 4 hours. He covered all the windows and ducts and ran a special machine that supposed to check and detect any leaks of energy. The end results of the test came out good and this was a good relief. The installation of the HAVC system went smoothly and without any issues. The work took 2 days and the new system start to prove itself. I must admit that I’m happy that I was referred to this company and that I hired them for this work.
