Paul had two out of four systems replaced. The system in the kitchen area is a two zone . The person that installed the system wired directly to air handler. The dampers are up in the attic. This is a two person job to label and figure out. It’s about a 1/2 day or so on this system. The air handler is also running on low speed. Once we figure out if the zone system is functional or not Paul will decide if he wants to keep the zoning or bypass and seal off dampers. Most of the wires are 4 wire. You will need a thermostat that operates with batteries.. He will like a quote on installing hurricane straps on the two new condensers. The office put quote together on figuring out what is going on/ labeling. Once we figure out we will go over the other options.. There is a quote on installing each thermostat and programming.
