Dedicated AC line - Contractor wants to use BX instead of romex

I’m having a dedicated in wall AC cable run, about 40-50 ft. I was planning on using VH audio cryo’d 10-2 Romex but the contractor wants to use BX since it’s an urban area and more impervious to mice, etc.

Any thoughts on this?

Also I was planning on wiring the end of the run with an 20 Amp IEC connector so I could plug it directly into my Niagara 7000. I don’t know if they will wire it this way but I thought I could always do that myself later.

Only commercial construction and over populated densely packed & infested cities require conduit.
Not in my red state. I was required to run through conduit in one of those areas populated by cows more than people. Single story ranch. You need to quit generalizing. If you are a licensed electrician you should know there are codes where conduit is required for certain applications.

40 to 50 foot run of BX ,
In Chicago BX could only be used for short runs ( 6 -8 feet )  
the rest had to be conduit .
So to have your cake and eat it to ask your electrician 
if he'll run 3/4 inch greenfield ( flexible conduit )
 for you with your 10/2 romex inside 
with a ground wire or a dedicated grounding rod .

Just make sure to check with your insurance company :-)

The contractor should wire it how you want them to and use your wire as well and i think that running it in conduit is a good idea that is what i did along with two quad outlets installed.

OK good times.  So Op in your situation and zip you do need conduit as same as vair68robert states for his zip BX is really intended for sub 10ft runs though some inspectors may interpret BX as flexible conduit.  As a result the most likely best path forward is to use the hi purity copper in conduit.  Cheers. and sorry for the disruption to the thread, the door was flung wide open and well I couldn't resist.
