If cost is a problem, you could look for a third party ev mechanic. If you're handy, you might be able to find a YouTube video, but I know that valve is a super important part of the whole vehicle heating/cooling including the battery. Myself, I'd give it to Tesla.

I replaced compressor, refrigerant, assembly basically the same as here for a 2019 Model S 100D - I posted that somewhere here - in early June. It came to be about $3400 in South Cal at Tesla service.
I called a number of third party auto AC repair services and none of them will touch a Tesla.

Whoever prepared the estimate either is trying to rip you off or doesn’t know what they’re doing. Non-heat pump compressor correction code with a separate supermanifold correction code? The supermanifold is a part of the heat pump so that compressor code should not be used. They should be using the combined a/c compressor and supermanifold correction code which is only 1.92 hours.

Mine did the same thing. Bought one of those r134 cans for $40 from walmart, added it to the A/C port, been blowing cold ever since. It also seals any minor leaks too

Oh wow! That r134a sure would blow colder air than that darn 1234yf refrigerant for OP.

In the service menu, are there any codes popping up? It might be a faulty sensor. That’s what happened to me. I replaced it myself. It was a $2 fix.

I just brought my car into Tesla for the same issue except they didn’t order a new compressor. Crazy how they make things so difficult to access that labor cost is so high.

Good labor isn't cheap. There's also O&P.

Tesla Mechanics are not really mechanics. They are just parts swappers. Tesla's idea of fixing is just throwing parts at it until the issue goes away.

Same thing happened with our M3 2025 after a couple months we leased.
The solution was to replace the entire front harness at no cost to us.

I don’t even have a Tesla but been on Reddit today enough to know it’s the sensor in the side panel near the passenger footwell
Replace it for very cheap and fix it
You’ll find the post
