We were recommended to American Home Mechanical through our home warranty company. They had first referred us to a different A/C company, but when that company called me back (actually, they didn't, after being told that they would call me between 8-11 to set up a service appointment, I had to call them back!) they were not able to see us unit Monday morning! This was on a Friday and we had been without air since Thursday night! This is Las Vegas in the middle of summer! Anyhow...our warranty company contacted American Home Mechanical and they agreed to come out THAT night between 7 and 9!! How awesome is that? Anthony arrived within the specified times after giving us a head's up call. He checked out our unit, immediately diagnosed the problem, fixed it, checked to make sure all was working well and was off to his NEXT customer. I highly recommend this company!
