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

"Jordan did an excellent job installing my new furnace and A/C unit. He was very professional, knowledgeable, and took the time to explain everything I needed to know. I could tell he takes pride in his work—he is detail-oriented, careful, and truly a perfectionist. The installation was done neatly and professionally, and he made sure everything was working properly before leaving. Jordan was an excellent find, and I would highly recommend him to anyone looking for quality heating and cooling service."

"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."

"The repairman was extremely courteous.  There were some issues with the air conditioner so he offered to do additional repairs which seemed a bit expensive, but the results were great.  Would have them do additional service in the future.

"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!"
