Diagnostic completed. Client reports temperature varies dramatically across home. Found approximately 3 year old Daikin Fit as well as similarly new ducting system. Master suite being fed by single 12" flex that travels significant distance from handler on opposite side of house. Master bedroom has single 8" flex coming from mixing box connected to private 12". Home should have two separate air conditioners and ducting systems. Alternatives include increasing flex diameter of master flex runs, dividing existing ducting into zoned system, or installing mini split inverter into master bedroom and possibly second head in office. Discussed options with client who wishes to review prior to moving forward. No further action necessary at this time.
