Upon arrival found evaporator coil completely frozen up, turned outside unit off and explained to customer that weâ€™re going to need the coil to drain ice. Will need to return. Upon arrival turned system back on and checked pressures. Found system to be about 2-4lbs low on 410-A. Recommended leak search or leak seal, homeowner wanted to just put Freon in system. Added 3lbs of 410A to bring systems pressures up. System is now cooling properly at this time. Freon does have the potential to leak back out.
Performed a one system maintenance checking heating, checked all electrical, mechanical and safety components, cleaned flame sensor, adjusted gas pressures, checked amp draws and capacitor. Found that the blower motor bearings are going out and motor could fail at any moment. Recommended replacing blower motor, but also if system is low on refrigerant again next spring recommend system replacement.
Completed one system fall matience. Blower motor is failing, it is overlapping, making a winding noise and leaking oil. Customer advised to replace immediately to prevent breakdown. I also checked heating components and safety switches. Left estimate with customer.
