During the hot and humid summers in Monroe, NC, your air conditioner will work day and night to keep your home cool. There shouldn’t be any smells coming from the cooled, dehumidified air that blows through the vents during a cooling cycle. If you notice any of these unusual odors, it’s a good idea to contact HVAC repair experts for an AC equipment inspection.

Musty or Moldy Smells

Musty or moldy smells usually result from high humidity or extra moisture. Check your AC’s condensate line. If there’s algae or muck in there, clean it out. Check the air filter and vents, too. Dirty air filters and vents could cause these stale smells. Our NATE-certified technicians also do this during a springtime AC tune-up. If the condensate line is clear, there could be moisture or condensation buildup elsewhere in the AC system, which will require professional attention.

Burning Odors

Air conditioners use petroleum-based lubricants. They also have a multitude of electrical connections. A loss of lubricant could result in a burning odor from overheated moving parts. If it’s the first time you’ve used your air conditioner in a few months, dust and debris on the coils or in your vents may cause this burning odor. A chemical type of burning odor could result from hot wires or burning insulation. If the odor persists for more than a couple of cooling cycles, you’ll need prompt service from HVAC repair experts.

Chemical Aromas

Chemical aromas that smell sweet or like ether are often the result of a refrigerant leak. A chemical aroma could also result from an oil leak within the AC equipment. Refrigerant and oil leaks are issues that demand professional attention. Only EPA-certified technicians should measure, repair and recharge air conditioner refrigerant chemicals, explains the Department of Energy.
