Performed cooling tune up on 9 year old package unit. Cycled system for cooling. Checked unit electrical and system components. Temperature split is within range and system is cooling efficiently. Primary motor control is In good condition and secondary motor control is within range. Filter is still clean. Homeowner is unaware how to use the thermostat. Tried to show her how to operate thermostat to the best of my ability. Homeowner does not wish to renew ESA at this time. A lot going on at the moment and she is unsure what she is going to do with the home.
