Dispatched for AC not working. At arrival the system was not operating but both thermostats were calling for cooling. Found the upstairs thermostat was not communicating with the zoning board. I reset the thermostat and reprogrammed it to the zone board. All zones are working as they should now. Once that was fixed I found the outdoor unit in error code 04. This code is protecting the compressor from over amperage and due to a low capacitor. Outdoor unit needs a compressor saver and a capacitor to prevent more failures. The bower wheel needs a deep cleaning due to dry wall dust buildup. This is creating extra strain on the motor during startup and is making it unbalanced. To prevent any other failure a duct cleaning, blower cleaning, evaporator cleaning and a polarized filter is needed to remove the dry wall buildup through the system, and to provide healthier cleaner air inside.
