A friend just had a whole new new system put in a 1600 sq ft ranch house. He had estimates from 10k -18k. Wayne was the highest. He went with one in the middle, around 12k. I know an electrician in SA, he said Wayne can only change out systems, they don't have any repair guys, only installers. He said he has seen numerous violations from the Wayne guys in regards to the electrical side of those installs. He said a few were extremely dangerous what the Wayne guys did, broken and botched together electrical connectors.
Hope you have good luck with it all, at least it has cooled down!
