Air conditioning odors may indicate a number of problems. In most scenarios, there’s no need for alarm. Even so, you may need to clean the HVAC and air duct system. We’ll go over some of the common odors and what they mean.
Do you detect a musty smell not unlike sweaty body odor? This may be a sign of mildew or mold inside the HVAC. During the dehumidification process, moisture collects in the air filter and duct-work. Mold can grow in as little as 24 hours if the moisture does not completely evaporate.
Address this problem by calling in a professional to change the filter and inspect the drain pan to make sure it’s draining properly.
Does the odor have a tangy smell, reminiscent of distilled vinegar? This may occur because the electric motor is emitting ozone. The smell is mostly harmless, but some homeowners with sensitivities may experience allergies.
You shouldn’t smell tobacco unless someone in the home is a smoker. Cigarette smoke residue can accrue in the coils and air filter. The odor likely won’t be noticeable to the smoker but will be obvious to non-smokers.
The odor of smelly feet or smelly socks likely means you have a blocked drain pan. This requires your immediate attention since a clogged pan leaves the AC prone to mold/mildew growth.
A rotting smell may be an indicator of a decomposing animal, likely a bird or rodent. A rotting animal corpse isn’t a health hazard, though the smell may make you a bit nauseous.
The furnace and dryer vents can also cause less-than-pleasant odors. This is why you should call Aurora Edmonds Furnace Cleaning if you notice any abnormal air conditioning odors or other unusual smells.
