One problem is that no one seems to know that AC systems recirculate air. I literally can't get people to believe me when I tell them this. When buying a window unit recently, some models had the ability to incorporate fresh outside air but the cheaper ones didn't. My home is leaky enough that I worry more about keeping outside air out rather than in, though.
- bluGill 6y agoThe ones that bring in outside air (that I have seen) just let a little outside air in. Most of the air is still recirculated, but there is a tiny hole that opens to let some air in.

- tgb 6y agoI think this actually makes it more understandable. If recirc is a special mode you have to activate in your car's AC, then it's reasonable to assume it's not the default mode for your house AC too. Since they never had a 'recirc' button to press at home, they'd assume it doesn't recirculate. Reasonable, but inaccurate.
- stx 6y agoUnless someone who has it is inside your home I don't think you need to worry about the air recirculating. I agree though its amazing that people don't understand how this works.
