Hi Casey, great question. No it really doesn’t replace an AC unit. It’s just a very fancy fan that blows cold air, hehe. It will cool a room down and circulate the air flow but it won’t keep you nice and chilled on those hot summer days. Best thing about this unit is the power it delivers in cleaning the air. The fan is just a bonus. Now if you are looking at the HP04 that is the addition of a heater built in, that’s really nice for cold days.
