Came out to perform preventative maintenance on air handler system for customer. Discussed with customer about maintenance being provided, filter needing changed, and anything he has questions about. Customer stated the system has been working and thinks the filter is most likely due to be changed. I inspected and changed the filter for customer. Inspected the evaporator coil, blower assembly, motor, electrical components, wiring, capacitor and heating elements. Found the capacitor in need of replacement and let customer know that it’s the reason the motor is running a little hot. Customer had me replace it. After replacing the blower capacitor, I cycled the heat on. Checked heating sequence, amps and temperatures. System is heating properly at this time.
