This question probably makes me sound like an idiot but I cant figure it out online. Im in California where the air quality is awful due to the fires and I have a little one at home. We are staying inside and have a Gree mini split system. If I turn it on for heat or AC, will it pull air in from the outside or does it only recirculate air from the inside? If it pulls air from the outside I definitely wont use it, but we are cold . Thank you!
