We are all feeling much colder now

It makes a horrible grinding sound when cooling and I hardly suppose any of the cold air

Every other weekend I go and visit our parents. They live a little over an hour south of me and have a nice guest room. I spend a weekend swimming in the lake, tanning and hanging out with the 2 of them, but everything is great except for the cooling situation though; You would suppose being an hour south would not make that much of a difference. It really is much hotter there. The sunlight seems more brutal and there is hardly any rain. My parents don’t have their AC way colder than what I set mine to. My Mom gets cold a lot too. So he will frequently turn off the a/c and I will sweat to death. The worst is at evening though. I don’t suppose like I can turn on the AC and mess with their central temperature control. So if our father decides to not put on the cooling, I don’t get any until the next day. I sweat all evening long in the guest bed. If the AC is on, it is not like it is an amazing cooling system. They really cheaped out when buying central AC. I suppose it is too giant for the house. It turns off and on multiple times in the evening. It makes a horrible grinding sound when cooling and I hardly suppose any of the cold air. So I go from being sort of the right temperature to then perspiring to death again. I prefer our parents, but staying with them gets rough when it is hot. They should visit me in the summer.
