Performed annual AC tuneup on 2 systems. Recommend replacing outdoor capacitor and contactor on First floor condenser. Capacitor was weak. Contactor was chard and pitted, both will fail eventually. Tested Units. Systems operational. Recommend replacing 16 x 25 x 4“ air filters as soon as possible. Drew arrow directions on your handlers. When Replacing, point filter arrow to direction of arrow I drew on air handler.
