When technician arrived he asked the homeowner if there are any troubles and was told everything is working good. The outdoor unit was pretty dirty and full of leaves so I removed the top and removed the leaves and washed outdoor unit. Then checked volts, amps, temperature splits, refrigerant pressures including superheat and subcool, capacitor, and contactor, also checked the blower wheel, filter, and duct pressures. Everything is working ok at this time, I told the homeowner filter is not horrible but should be replaced before next maintenance.
