I recently performed an AC tune-up for a club member. As an HVAC technician, my responsibilities included inspecting and cleaning the condenser coil, checking the refrigerant level and charging if necessary, checking and adjusting the thermostat, cleaning the air filters, and lubricating moving parts. I also tested the electrical components, such as the thermostat and the blower motor, to ensure they were operating correctly. Finally, I performed a safety check to ensure that the unit was operating safely and efficiently.
