I checked the capacitor it was in rehang at 45.4/5.1. The contactor has some rust marks but is working. I cleaned out the condensate pump then test it, condensate pump is operating properly. Performed a amperage readings on the condenser fan motor and the compressor and blower motor all are operating properly at this time. Changed out 16x25x1 filter system is operating properly at this time. Manufacturer Carrier Model # 25HCE418A300 product #25HCE418A0030011 Serial # 2716E20265 Completed the maintenance on the second unit. Changed the 30x10x1 filter supplied by the customer.
