What to Do If Your AC Smells Strange
If you’ve noticed a strange smell from your AC, don’t ignore it. Your air conditioner could be warning you of a bigger issue.
While a musty scent during first use is often harmless, stronger or unusual odors like a dirty sock smell, burning, or a gas-like odor could signal problems such as mold growth, electrical issues, or even a freon leak smell. A blocked drain pan, frozen evaporator coil, or excess moisture in your ducts are all common culprits when your AC smells like gas or mildew.
Before calling a professional, try basic troubleshooting: replace your filters, check the drain pan, and ensure the condensate line isn’t clogged.
However, persistent or dangerous smells (especially if your AC smells like burning or exhaust) require immediate attention from a licensed HVAC technician. Routine maintenance is key to preventing these issues.
Are you asking, “Why does my AC smell?” If so, it’s time to schedule a checkup with TDi Air Conditioning and breathe easier.
