Upon arrival filters where clean, went to attic, blower is clean, coil is clean. Coil has rust but found no leaks during leak search. Found blower motor not running full speed like it should and shutting down. Need to get blower motor before we can continue to check system. Upon arrival shut power off and pulled blower. Pulled old motor out and put new in place. Wired everything back up and started system. Blower is pulling .6amps. Wires all tight, indoor is running. Went outside, contacter checked out good. Capacitor checked within specs. Refrigerant levels where running at a 16° subcool where unit calls for. Let system run awhile, and system is working good. Explained to customer with both units and the age of them anything can happen but the systems are running g good at this time. Upstairs is set to 74° cooling and is cooling at this time.
