3 system a/c repair and tune_up complete. Found weak blower motor controller in the upstairs system (7.5 uf). Found weak blower motor controller in basement system (5 uf). Found main level system very low on r22 causing system to freeze up. Found basement and upstairs systems both slightly low on r22. R22 is being phased out by the EPA in 2020. Chemically washed condenser coils. Recharged the main level system with 4 lbs r22, recharged upstairs and basement systems with 1 lb r22 each. Added leak seal to all systems (not guaranteed). Replaced upstairs and basement blower motor controllers. Systems are cooling at this time. Customer upgraded tune-up to a Comfort Club Membership plan.
