Attention Louis Bruno: Johnathon did a good Job. However the person that sold me the A/C system should have had installed the stage 1 Biocide System Sterilize when they installed the A/C system. My insurance Co. would have paid for the installation ( we had a surge during a lighting storm that broke the A/C system). However as it is I had to pay $1,100.00 out of my pocket. A lot of money for a retired person on a fixed income. The sales check list did not have it as an item to be installed.
