Performed a.c. maintenance in fair oaks. Unit is a rheem package unit on side of house. Unit had a lot of debris in compressor compartment so I removed them. Washed coils down with hose to improve efficiency. Checked all electrical and is okay. Capacitor was changed in 2017 and is okay and in range. Checked blower motor and does not have alot of dust buildup on it. Duct work looks okay and in tact.
