I have 4 month old carrier AC. Cleaned it’s filter 2 times . From last 2 days it is smelling bad odor, just like wet clothes kept from few days. What should I do? Bad odor only last for 5 min after running ac but smell restore when I keep ac OFF for 5-6 hours
Try without the filter for a few days and see if it still emits the same bad odor, we need to work it out from there.
