The post about appliances got me wondering... I usually install the AC Discos and let the HVAC crew install the whip and wire the condenser. I'm doing a small (8 unit) subdivision and the HVAC crew don't want to make the final connection. I wouldn't agree to do this on a 3 phase compressor, but since this is residential, I have been connecting them for a small fee. I have also been installing a shut-off on the gas-fired furnaces and making the connection to the unit.
I'm in Utah and when I do new construction on a single family dwelling I install the breaker in the loadcenter and run the wire from the load center to the outside wall where the A/C unit will be. The hvac guys install a disconnect and wire from the disconnect to the A/C unit.

I never had an A/C of furnace hooked up by the HVAC guy. They set the unit and normaly do the low volt stuff. We provide the wips, disconects and hook them up. A HVAC guy told me they sometimes get everything as a kit. Furnace, A/C, line set, pad, disconect, & wip. They just keep the disco and wip for other jobs.

I usually just take the circuit to the disconnect, which I furnish, and leave the rest to the HVAC contractor. Around here, HVAC guys cannot be depended on to do their work in a timely manner (generally speaking) and I am usually done & gone by the time they get around to the condensor & furnace hookup.
Few things are harder to put up with than the annoyance of a good example.

Surely we're not surprised that almost every A/C install violates NEC, are we?
I like to do it all- including the T-stat wire. Trouble is, I often have no idea where the unit will sit.
The almost universal NEC violations are: -T-Stat wire run together with power leads from the disconnect to the unit, or the wire run unprotected along with the line-set; and, -The condenser set in front of the disconnect. -The flex run unsupported.
A mechanical code violation also often seen is failing to mount the condenser on a proper pad; the shipping skid is not a proper pad!
So, desires aside, I usually end up running to the disconnect, making my best guess as to where the unit will sit- then hope for the best.
