Performing diagnostic service on 2011 York condenser - fan motor is not functional at this time, only compressor motor is coming on. Condenser fan motor has failed due to previous power issue in Discovery Bay. Ordered new motor and will return to replace ASAP so clients can remain cool during brutally hot summers in this area. Recommend annual maintenance to be sure system has no further issues and allow us to catch small issues before they become big problems. Peace of mind is very important!
