So here's the thing when it comes to making a house cooler than normal, it's generally best when it's a smaller stand-alone soundstage like 22, and not a bigger one that is sharing multiple houses like 23 or 24. One of the most notable cold houses was Winter's Night, it was in soundstage 22 and those who went through it can confirm it definitely was colder than other houses.
Now as for Poltergeist, it was alone in soundstage 25, and it also had fans blasting you in various spots so it got notably chilly at times in there.
As for Yeti: Terror of the Yukon, it didn't feel colder since it was in a shared soundstage along with Us in 24. It just doesn't work for chilling things since you got a bigger space to cool and you're sharing space with a house that might not fit being colder than normal.
