No cooling, no power at thermostat. Indoor disconnect for air handler has loose connection internally, need to replace disconnect box. Did a complete evaluation of system. Found several areas where there has ductwork leakage in flex and Plenum’s. There is an old 5 inch media air filter that was never changed and door was hanging off sucking in hot attic air, compressor had high start up amps and contactor was burnt and pitted. Gave client solutions for issues with system, however, system is 21 years old and recommend replacing system and ductwork due to age, condition and cost of repairs.. Client just wanted to do the Band-Aid repairs for now and replace ductwork. Replaced disconnect box, sealed on door for media filter so it does not leak anymore air into system from attic, replaced contactor, and installed hard start kit. Scheduled installers to come out on Tuesday, July 15 to replace all ductwork in attic. Cycled and tested system, all operations OK at this time.
