Why Does My Ductless Mini-Split in Indialantic, FL, Smell Bad?

When your ductless mini-split in Indialantic, FL, starts smelling bad, the system is warning you that you need to take action. It may even signify the system is on its way out. Here are some of the common odors you might smell coming from your ductless mini-split system and what they mean:

Rotten Smells

A rotten smell commonly indicates a dead animal. Smaller animals like squirrels, birds, and mice can get inside the system and pass away, leaving behind a foul odor that the mini-split keeps pushing out. You may also pick up a slightly fishy odor.

Chemical or Vinegar Scent

Homeowners often pick up a scent they describe as smelling like distilled white vinegar or an unknown chemical. This smell occurs when something inside the mini-split system burns or overheats. Though you may detect a burning odor, it’s more common to smell vinegar or a chemical.

Musty Odor

When you have a problem with the condensate drain line, you may notice a musty odor that smells like dampness. A clogged drain line occurs when something blocks the line, which allows moisture and debris to back up. As the debris breaks down, the odor will worsen.

Sewage Smell

This unwelcome scent can come from your ductless mini-split system. It typically develops due to a buildup of wastewater, such as a clogged sewer line or backed-up drain. The system picks up that odor and circulates it around your home with cool air.

Sweet Odor

Though chemical smells can relate to overheating or burning, they also occur when your ductless mini-split system has a refrigerant leak. Refrigerant has a strong chemical smell, but many people also detect a slightly sweet odor. Since a refrigerant leak can make you sick, seek professional help as soon as possible.
