Air conditioning smells like attic.

Here is useful information on the smells that may be coming from your air conditioning vents. Mold and mildew growth is the most common cause of bad smells in your ac system. Here are 5 common hvac odors and what they indicate. Since then the a c has smelled like the attic though we notice nothing from the heat in the winter.

However some smells like rotten eggs or gas are more serious. If you are experiencing an electrical burning odor or gas smell turn off the unit and call your hvac technician right away. They carry air to your living spaces. If wet for more than a couple days mold grows generating a musty odor.

If your cooling system was a body the air ducts would be the respiratory system. Ducts in attics maybe accumulating condensation during the winter when the attic is cold. Other contaminants in your hvac system will do the same if left unattended. The key is to keep enough circulation of warm air through the ducts to avoid condensation when extreme cold in winter.

I recently when up there and taped up all the joints nipples and boots so minimize cold air blowing into the attic or being sucked from the attic. But if air ducts leak disconnect in a dirty non living area like your attic or crawl space they draw in the surrounding air which is usually filled with dirt dust and mold spores. If there is excess humidity or moisture in the hvac system you could end up with mold and mildew flowing through the ductwork.
