Bill at A&M is just the best guy out there! He doesn't stick it to you or make up BS charges or say you need a new unit when you really don't or use scare tactics. He is an AC guy who knows his stuff, has reasonable prices and shows up when he says he will. The 2 emergency ac outrages i have had he came out right away and had us back chilling that day on both occasions (two different units). Bill has also checked out units for me prior to buying a house. I trust what he says is true. I am grateful to have Bill as my go to AC guy!
