Garage Door Openers Air Conditioner Repair Air Conditioner Filters Portable Air Conditioners Question: serious question – bought a machine last summer, no smell, now it smells awful! filter is totally clean. Answer: Freon has no odor to speak of. You most likely have something in the coil or coil area. I’ve taken mouse nests, dead rats, dead birds etc… out of these things. You could also have some kind of mold or bacteria growing in the unit. It needs cleaned!
