A burnt smell could mean something is seriously wrong, like:

How do I get rid of the smell in my AC?
Clean or replace the filter, flush the drain line with bleach, and have your evaporator coil cleaned.
Is it normal for AC to smell musty?
Not after it’s been running a while. A persistent musty smell is often due to microbial growth in the system.
What if my AC smells like chemicals?
That may indicate a refrigerant leak or a failing heat exchanger. Call us immediately—this can affect your health.
Why does my AC smell like rotten eggs?
If you use natural gas, it could be a leak. Evacuate and call emergency services. If not, it might be a dead animal in the ductwork.
