            These people are crazy! They came to look at my AC this spring and couldn’t repair it and wanted to replace it at a cost of $12,000. I then called them back to hook up a mini split AC that I bought for 650 that had a leak. They wanted $1800 to get it hooked up! These people are nuts! Avoid at all cost !
