:confused:My air conditioner is putting off kind of a weird smell. It doesn't coincide with any of the questions or answers I've seen so far on here. I live in a single wide mobile home and have a window unit. My A/C doesn't smell like dirty socks or anything else like that. I also understand that Freon has no smell. So I am not sure what is wrong, if anything, with my A/C. It sort of smells like the inside of a freezer.....I really don't know how to explain the smell. Like I said, it's not a foul odor but I have had a bad headache for about 3 days now and I'm 3 months pregnant so I wanted to be sure the A/C is ok. I have been running the A/C nonstop for the last 3 days because I tend to get sick from the heat and it has been HOT HOT HOT! The smell has appeared only today. The A/C in my car smells similar at times. I was wondering if anyone can give me any advice? Thank you so much.:confused:
