When we went to look at the wiring tech hunter found three rats in the wiring. We hooked the gauges up to the second unit the supper heat was at 2 due to the strain on the unit trying to keep up with the heat. Comfort Advisor coming out nest Saturday. The homeowner would like for the office to call and set a time for a electrician to come out.
