Summer AC Maintenance Performed Upon arrival system is working and operational. I began my maintenance at the outdoor condenser, customer declined condenser cleaning service today due to company. I inspected electrical components for wear and tight connections. I checked refrigerant pressures and charge. I tested system amperages. I then proceeded to the indoor furnace unit. I measured temperature splits. I checked condensates for proper drainage and safety. Filter was changed. Inspected electrical to ensure tight connections and monitor wear. Inspected blower compartment for dust and dirt as well as proper balance. Upon inspection of both units, I found there to be no electrical protection on either, recommend having surge protection added to protect sensitive electrical components. Upon departure system is working and operational.
