This depends on exactly how well insulated the room is, the wind speed outside, temp outside, the age of your air conditioner, cost of electricity, etc...

This is a hugely complicated problem, not because it is hard, but because there are so many factors. Mind you they are factors that can halve or double your cost.

So do like the rest of us and just log your electricity bills, because it is extremely far from practical to calculate.

I was just looking for a guess on how long it'd take to cool my room so I could set the timer on a newer AC unit for an optimal time to get home to a cool room.

I guess it would just be best to guess and see what I get after a few tries, right?

Yes, the problem is sincerely too complicated to put on paper. I mean you could but it would take hours. And any simplification of the problem would be an incredibly rough guess.

You are best off trying your own experiments and log everything. That will be the easiest and most reliable way to learn what you want.

Alright, I appreciate the advice. Thank you very much.

I used to use these, will probably take you about 3 hours depending on the humidity and how much other airflow there is in the room

Combine it with a fan and it would take less than 30 minutes to reach a comfortable temperature.

That's the rating system ACs use m80

this question cant be answered without doing a CFD simulation
