We have a dehumidifier in our basement, where my office is. Last fall it started blowing hot air. I cleaned the filter (which I didn't realize it had) but that didn't change anything. I've tried googling it and there's a lot of varying information on the internet -- from people saying "it's supposed to blow hot air, thats how it work" and other's saying its broken. I don't expect it to cool the air, but I've had it for several years and its always just vented air that was about the same temperature as the room. Maybe a little warmer, or cooler, I'm not sure I never thought anything about it. But now it blows hot air, like to the point that it actually raises the temperature of the room significatly. That said, it is working - it fills the bucket with water. So I feel like that means its not broken? Thoughts?
