I have noticed a strong musty smell coming from my cabin air circulation when the A/C or blower is running. This happens during wet days or a couple of days after wet days. However, during completely dry weather, this smell subsides. I have also observed that the smell on rainy days comes from the outside air mode, and on dry days, it comes from the recirculation air mode. Has anyone else experienced similar symptoms? Will the Aircon refresh work? Should I get the drain pipes cleaned? Can anyone recommend a garage or technician in the Berkshire or Surrey area?
