Mini-split system smells that mean trouble.

HVAC systems ideally should not smell. If a mini-split does smell, the owners must get in touch with a certified HVAC professional. 24SevenHVAC, an HVAC system installation in New York, discusses the various mini-split odors and what they entail.

Musty or Moldy Smell

A musty smell is a sure-shot sign of mold spores in the mini-split system. As condensation builds from the moisture trapped in an air conditioner, it needs to drain correctly. When the water doesn’t drain as expected, it can provide a perfect atmosphere for mold to grow. Like dirty socks, this smell means that mold spores are multiplying, entailing severe health effects for the inhabitants. Left unaddressed, mold spores can circulate with the HVAC air throughout the house and spread. The best practice is to clean the drainpipe properly to prevent such a scenario.

Fishy or Rotten Smell

Something smells fishy? Don’t delay the inspection. There is likely a dead animal in the unit. Small particles like bacteria will slowly emanate from the decomposing body and make their way out from the mini-split. Sometimes the dead animal may be in other house parts or inside the walls. Make a visual inspection to find the source of the smell. Removing this odor from a mini-split can be challenging, but this can be achieved with professional cleaning. This cleaning is crucial to maintain good air quality indoors.

Chemical or Vinegar Smell

A vinegar smell could be caused by an electrical problem and accompanied by chemical residue on the damaged components. When mini-split smells like acetone or nail polish remover, a refrigerant leak is a likely culprit. Turn off the mini-split until repairs are done to avoid further damage. If the mini-split is too old, it is wise to replace it to avoid investing too much money in repairs and utility bills.

Burning or Electrical Smell

A mini-split comprises various electronic components such as power wires, fans, and compressors. A burning, electrical odor can stem from any of these parts. A damaged wiring, a failing motor, or an overheated component are examples of electrical problems that lead to a burning smell.

In these cases, the mini-split must be turned off. In these cases, owners must not attempt a DIY as it could prove dangerous.

In other cases, the accumulated dust over prolonged inactivity can start burning off when the mini-split is turned on. This is a temporary issue that doesn't warrant any concern. Filters are great for collecting dirt, dust, and debris, but it all starts traveling through the system if the filter isn’t clean. So changing the filter regularly can prevent the accumulation of dirt.
