Did some more probing and reading about IR. I found I had the wrong schematic for TV B Gone. Took it out and did some continuity measurements. All the output drivers are tied together to a single transistor which is then driven by an Atmega pin. This is a better design than the 1.2 schematic I was using. Found the new schematic online as ver 1.3 I eventually found that I was keeping the IR LEDs on because the final output was a "zero" which enabled the LEDs. . After the device emit the code sequence, I put a statement in to turn the LEDs off. This was a one on the output pin. This made a difference. The A/C can now be turned on or off with the test button without doing a power cycle. Dinner was Cajun rubbed Tilapia with corn Mach Choux and Shiraz. Desert was Moo Lineum ice cream.
