Came out to call. Customer stated AC wasn’t cooling properly. I checked system over and found the capacitor had gone out. I discussed with customer customer repair needed and pricing. Capacitor is under warranty, but labor isn’t. I replaced the capacitor and cycled system on. I found the AC to be low on refrigerant. System is running at a 4 degree subcooling and it needs to be ten. I added 1.6lbs of 410a to get proper subcooling. System is cooling properly at this time. I recommended customer replace coil in attic seeing there could be a possible leak in it.
