Can a residential air conditioning compressor's disconnect be a small circuit breaker exterior panel box? I have a 4-3 romex feeding the area and I wanted to put a small 2-4 sub panel to also run some other small loads. The A/C is a 40A unit. Can a 2-pole breaker in the small sub panel be the means of disconnect for the A/C? Thanks in advance for your input.

It sounds like you are just putting a wp sub panel near the a/c. It should be no problem unless the a/c calls for fuses only.
 
other loads

other loads

4/3 Romex ? 4/2 w ground or 4/3 with ground
my first thought (fear) was 120v loads being tapped off a feeder with no neutral

Sounds like a disconnect to me. Remember also, within sight, blah, blah, blah...
 
I see a lot of A/Cs being fed from one circuit and a sub-panel. If the feeder is large enough to handle all loads and it is a 4-wire feeder, go for it.
 
If you have an existing 4/3 w ground feedind an AC disconnect, you should replace the disconnect with a 6 circuit wp panel, refeed the AC unit and use the other circuits for your small loads. I just looked at a new Carrier(I think) condensing unit today and it said Max Fuse or circuit breaker. Im going with the breaker
