Our AC went out in July, Walker came out immediately and assessed the issue/proposed a solution. After looking at 3 other proposals, we chose Walker. Also they had been recommended by 2 reliable sources. They did an excellent job replacing the AC/furnace and entire system quickly-so we didn’t have to be in 100 deg weather long with AC. The crew was courteous and cleaned up our property before leaving. Unfortunately the unit installed was defective(not their fault!!) After 5 weeks, the compressor failed. This was Labor Day weekend! Again 100 deg temps. Walker came out the next working day and replaced the entire unit! Again, quick, thorough and neat. By that night, our house was cool again. I’ve recommended Walker to family and friends and they also are very satisfied. They’re fair, honest and accommodating. I would not hesitate to recommend them again! Linda Glauben Dallas
