"My old central air unit went out and Mike (the owner) gave a quick response to my service call. I decided to purchase new central air. Mike and his crew member did an excellent job with the new installation. They were very hardworking and it was done in no time. Mike goes the extra mile, is very professional, and wonderful to work with."

"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."

"I called for service and appointment was for the next day. Service person showed up on time. The problem was found (bad micro switch) and a zone valve motor/actuator was replaced. The whole process was completed in 30 minutes. They give senior citizens a discount. Yea! I would use them again for other problems or maintenance."

"My lights started flickering throughout my house and my refrigerator wasn't keeping as cool as it should.  I could hear "crunchy" sounds coming from my electrical panel so something was definitely wrong.  I called "Sparky" and he was over in 2 hours on a Monday.  He diagnosed a loose terminal screw (because there were sparks coming from it) and had everything fixed in less then 5 minutes.  He only charged $29 for the service call and was very friendly."
