I have a back porch where my washer/dryer are. I have a small gas heater that I ran on low at night when the temp gets below 32. I have fairly new windows double-paned. I leave one window cracked for ventilation and there is also a doggy door. My problem is that there is condensation on the inside corner of the room that is closest to the doggy door. I don't know what else I can do. Please give me suggestions
