If your ductless air conditioner in Palm Desert, CA, is emitting unpleasant odors, it’s a good sign that something is wrong with the system. When it’s working properly, HVAC equipment shouldn’t produce smells. Read on to learn what that odor from your ductless AC system means.
Burning Smell
If it smells like something is burning, it usually means that there are electrical problems in different places in your mini-split system. A failing motor or damaged wiring causes the ductless AC system to overheat and produces a burnt odor. This needs attention from an HVAC service technician to prevent additional problems and ensure your safety.
Musty Ductless AC Odor
A ductless AC system that emits a musty smell likely has microbial growth, which could be due to dripping water or a wet drain pan. Airborne contaminants are unhealthy to breathe inhale. The system requires cleaning, maintenance and repairs periodically to prevent musty smells.
Chemical or Vinegar Scent
A sharp or acidic smell indicates that something is overheating and possibly melting inside the ductless air conditioner. A more chemical or acetone-like smell suggests that the refrigerant line is leaking.
Rotten or Fishy Smell
While a rotten or fishy smell isn’t as common as the other odors, checking the mini-split for small rodents or bugs, is a good idea. They can get inside if there are gaps where the condenser line enters the house. This doesn’t necessarily mean there’s an issue with the ductless AC system, but your mini-split will recirculate the odor until you remove the remains.
When you experience unpleasant odors coming from your home’s ductless AC system, have a professional HVAC company in Palm Desert, CA, inspect the indoor and outdoor units to pinpoint the problem. Contact Esser Air Conditioning and Heating for ductless AC services, including repairs and maintenance.
