"Service professor is on my speed dial for all my home repair and maintenance needs."

"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."

"Crome replaced my furnace and AC unit, very happy with the service. Very nice and knowledgeable technicians."

"Our A/C stopped functioning. They removed dust and debris from the coils in the 'inside' unit. They also cleaned the drainage hose that took condensation out. Unfortunately, they missed an overflow tray which filled up a few days later, overflowing above the ceiling of our living room. It soaked the plaster. We are still getting bids to fix it, but the bids are hovering in the ~$500-$700 range. VanderHyde was apologetic and fixed the problem promptly when notified, but the damage had been done. I think it was an honest oversight. But that oversight doubled the cost of the repair. I would still use them again.

"CHW was very responsive to our urgent need! We filed a claim the evening prior when we notices our A/C was blowing warm air into the rooms. Then by 8AM the next day, we had a call from the service technician saying he was on his way to address the issue! CHW worked with the technician to find out the compressor was the culprit and approved it's repair! Great customer service for a family in need during the hot south central Texas summer!"

"The two men were available to do the job the very next morning. I was afraid I was going to need a new central a/c unit. The guys went right to work and in less than an hour had my a/c up and running for under $100. I was extremely pleased!"
