The car is 2014 Mercedes E550 Sedan
I have been hunting the source of this issue for couple months already.
It started last year.

Whenever AC is on (Or hot air is on), engine performs poorly.
At least 25-30% power gone.
Car sounds loud and heavy.
IAT also up 10c
It still makes cold air.

At first, i thought its AC compressor or AC clutch issue.
So, went to a Shop, replaced AC compressor.
Shop also check on freon leak, no leak neither.

hoping to get some recommendations where to go

Any help is appreciated
