The detailed quote has the replacement Denso compressor priced at $1000. Same identical part is listed new on RockAuto for $296. Will shops not source from there?
Most shops will not source parts from Rock Auto if they can get the parts from their normal distribution sources. You're paying that high price so they can offer a warranty on the part/labor and probably a 100% markup on the part cost.
If it was just the clutch that blew up, you shouldn't need a new compressor, expansion valve, or a flush. Clutch can be replaced without removing the refrigerant from the system.
If something internal to the compressor blew up, you'll need all those parts and a flush to get any metal out of the system. Most places won't warranty AC components unless you do this. I'm assuming this isn't the case since they aren't also replacing the condenser. You didn't list the year, but if your Odyssey is 2020+, you have R1234YF refrigerant which is insanely expensive (compared to R134a) if the shop needs to top off the system.
Seems a bit high to me as well assuming you don't need refrigerant. What's their labor rate? Is this the dealer or an independent shop?
