Say it’s 25C outside and 30C indoors. I want to bring the indoor temp down to 25C, but opening all the windows barely makes a dent. Does it make sense to have the AC turned on and set to 25C while I have the windows open? Or should I be closing them anyway?
Thanks for this question. As the weather cools, I’ve started considering the same thing. Leaving the windows open overnight never seems to cool the house down enough on its own. I’ve been considering using the A/C to help, that way I don’t have to run it as much during the day. Glad I’m not the only one thinking this way.
I’m wondering if this will harm the operation of the air conditioner in any way, given that I have a whole-home HVAC system, and they’re designed to work with the windows closed.
