Arrived at customers home and was greeted at the residence. Customer directed me to the thermostat to put it in heat mode.. approached attic hatch in garage are and was unable to gain access into attic due to personal belongings in the way.. Also very small access area, would require small slim technician to gain access. Inspected heat pump disconnect and it is tight to the house and sealed… inspected refrigerant lines and they are neat and tight.. Armor cell insulation is intact and without rips and tears at this time.. Inspected contactor volts coming in is 242.8. And going out is 243.0 volts. Inspected fan motor and blade and found that fan motor has rust showing on motor housing but found no leaks from seals at this time. Inspected capacitor and it is in range at this time.. inspected condenser coil and found it to be clean overall. Inspected 20 x 25 by one filter found it to be dirty and replaced it with a customer purchase 20 x 25 by one filter. Overall system is operating no
