Air conditioners are an essential part of how you stay cool and comfortable at home, especially in Florida. But no one wants to cool their home at the expense of unpleasant odors or smells. If there’s an unfamiliar or unsavory smell coming from your AC unit, it could be a sign it’s time to schedule maintenance. Here are a some of the most common odor complaints people express when it comes to smells coming from their air conditioning.

Air Conditioner Burning Smell

burning smell coming from your AC vents is usually from three likely causes.

If there’s a fire in your home and the AC is recirculating the odor, call the fire department immediately.

If you notice a burning smell coming from your vents when the heater is turned on, it’s most likely the heating system burning off the dust that’s collected over the course of warmer months.

If you notice the smell of burning while your unit is set to cooling, turn your system off right away. This could be a sign of an overheating or malfunctioning motor or another electrical problem that should be addressed by a professional technician.

AC Electrical Smell

Electrical odors are perhaps the single most common smell people notice coming from their air conditioning system. If you notice an electrical smell at home, it’s most likely due to a mechanical failure. Burned wires and electric parts that make up your HVAC system could be dangerous, so turn your system off and contact an AC professional immediately.

Air Conditioner Musty Smell

In warmer months and more humid regions like Florida, it’s not uncommon to smell a damp and musty scent being emitted from your home’s AC. Musty smells coming from your AC vents are typically associated with water entering through attics, basements or leaks in your ductwork. Learn more about Dirty Sock Syndrome in this blog.

Mold, including Aspergillus, Cladosporium, and Stachybotrys (also known as black mold) is another common cause of bad smells. You will need a special mold killer solution, cleaning supplies and a professional service to accomplish this task.

A recently dead or decaying rodent causes a very pungent, unpleasant odor. You can remove deceased or rotting pests yourself or call a specialist.
