Completed 1 system furnace repair and preventative maintenance check. Changed filter. Dusted airhandler, air handler cabinet, and electrical compartment of the outdoor unit. Tested mechanical and electrical components and found weak capacitor for the outdoor unit. Changed capacitor out under warranty. Recommend hard start kit to reduce the load on the compressor to prolong the life of the system and extend the life of the new capacitor. The system is heating at this time.
