Performed ac tune up 15 yr amana split system. Changed filter for client. Found weeds growing into condenser, pulled weeds. Gave unit a bath to clean coils. Checked refrigerant charge, ok. Dual capacitor ok. Contactor doesn’t look great. Checked disconnect, it’s hard to pull it out but everything else looks good. Temp split is 18 degrees. Recommend signing back up on annual maintenance plan, to keep systems running more efficiently, and last longer. Resigning back up on the maintenance plan for both systems, so we don’t have to worry about maintenance anymore.
