AC performance tune up times one system. Change out filter client supplied. Verify primary drain is clear. Cast amp draw on blower. Test thermostat for proper operations. Check outdoor unit. Refrigerant level was low I added almost 3 lb r410a. Suction cap was missing and I installed one to stop leak if it is there. Office will call and schedule date for me to return delete search on system. System is operating at manufacturer specs at this time.
