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.

What do you guys do.

Thanks, and Happy Thanksgiving,

John

I do commerical. Around here we connect them.

The whip is always included in our price. I never really looked into this but I guess the standard set of specs has us doing this.

I have actually had AC guys follow one step behind me to start up the units after I hooked it up on fast track jobs.

My best guess as to why we hook them up is its inspected by the electrical inspector so if the AC guys do it and something gets red tagged, guess who gets the red tag?

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.

... We always connect them... We have an agreement with the local A/C boys,..they won't touch our disconnects,and we won't charge their linesets...

Here in MA and RI we do all the line volt work.

Sometimes the contracts require the HVAC contractor to provide the disconnects and they turn them over to us for installation.

Just wondering John, when the HVAC contractors do the connection for you do they pull an electrical permit?

That would be required here. they can not work under our permit, we would not let them anyway.

Here if the HVAC contractor even does the control wiring they must have a licensed guy on staff and pull a permit.

We do the Line Voltage connections in the unit, and they do the stat wiring.
We supply both whips.
Rarely do we stray from this.

John (Rojosy), Good to see 'ya!

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.

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.
