I arrived to perform a diagnostic on an air conditioner. Upon arrival, customer stated ac was not cooling home. They thought it was the thermostat, so they installed a new nest. But it would not come on. Nest tstat needed a common wire hooked up. Hooked up common and reset thermostat. Nest brings ac on not but nothing cold is coming out of vents. Found ac running but fan not spinning. Capacitor for fan side is dead. Replaced. Ac comes on and fan spins properly. Delta T 18. Pressures. 127/315 subcool 9.2.
