I came out for a no cool, on the upstairs system. I. Necked the ac over and found the dual capacitor at almost 0. The system is still under a parts warranty. I installed a new warranty dual capacitor. She cycled the ac, from the thermostat, and I checked all operations and charge. All working well. She’s already scheduled to have us out in a few weeks to do the ac maintenance, so I didn’t wash the ac coil today.
