Not so good, bought a new AC unit paid over 15k, send unlicensed two guy to install it, electrical work not completed as I was promise by Brooks, try to call him and didn't answer his phone, unlicensed tech! Wow, my friend bought two units for less price, for two story house. Y paid double and got a unit that don't know when it was made, he promise me. 2017, don't see that mark any where, I have to say until electrician comes I'll give the rest of the money, also the Mexicans were leaving and a some vents were completely not blowing any air at all.. plus more issues.
