Mario was super nice. He had to put up with the heat in the attic and a rattlesnake under the house. I will get the snake taken care of. I got 2 copies of the invoice, but didn't get a copy of what he did like I usually do. Please send that work done copy. Also, the TXU valve is out on the upstairs A/C. SW is supposed to send me an estimate on fixing it. I cannot afford to buy an new unit until I get the last one I bought paid for and I owe another year on it.
