System is a 5 year old 2.5 ton carrier split system. Tech called for heat mode and found outdoor unit energized in cooling mode. O circuit is not energized, but reversing valve is in the cooling position. Tech also found 35/5uf dual capacitor reading 7% weak on HERM side Customer also reported that air handler has dripped water in the closet before. Installing company came out, but could not resolve issue. There was water under air handler today. Inside of air handler is rusty where system has continuously dripped condensation directly off of indoor coil. Heating/cooling speed is set to speed tap 1. The heat strips are set to blower speed tap 2. Speed tap 3, 4, and 5 are not used. Tap 3 is high airflow. Tap 2 is medium (used for electric heat), and tap 1 is low (currently heating/cooling speed). Tap 3 works. Tap 4 and 5 do not. Likely unprogrammed from the factory. Tech does not have a guaranteed solution to prevent condensation dripping directly off of coil except to clean coil (alr
