For years we have used Chris with Control Temp but his numbers have been disconnected. He was the one who originally installed the unit when the house was built in 1999, but our unit we just replaced back in 2012 isn't cooling like it should right now. Last thing I want to do is freeze up our unit as we bumped up to a 2 and half ton unit to help us get through the summers in Texas and this summer has been pretty mild. Any good experiences with A/C guys in town since it looks like we need to find a new one?
