That funky odor!! Your air conditioner may actually be responsible. Air conditioners are supposed to remove mold-friendly humidity from your home, filter allergens, and keep your house well aerated – but only when they are in perfect condition. If you don’t keep conduct regular maintenance, faulty ACs will produce bad odors. Each smell is usually different and has a special message to relay. Knowing the different smells and what they indicate will help you stay ahead in repairs.

Burning Smells

If something smells like its burning, it probably is. A burning smell mimics a gunpowder like-aroma that indicates a short from the fan motor or the circuit board. The first step when you notice such a smell is to turn off the HVAC system from the breaker box. If the burning smell persists, turn off the power then evacuate the home. The problem could range from electrical to mechanical issues; an AC professional will ascertain the cause.

Rotten Eggs Smell

Provided you’re sure you don’t have any rotten eggs in the house, a rotten egg smell from the AC is a likely indication of a gas leak. Natural gas on its own is odorless, however, most manufacturers add an aroma for safety purposes so that in the instance there’s a leak, one can easily tell. A rotten egg smell warrants immediate inspection from air conditioning system professionals. Gas is naturally highly flammable and explosive, high-level exposure can lead to the victim being deprived of air causing loss of consciousness. The other cause of rotten eggs smell is melting Ac components. The first call of action once you notice this type of smell is to open all the windows before calling a technician.

Sewage Smell

Unfortunately, this smell is often a result of ruptured pipes, sewage backups or venting ductwork. Either of these will fill your home up with a not-so-lovely methane smell a stench that is nothing to laugh about. This type of gas is not only toxic, but it’s also flammable. Even at low levels, decaying sewage is dangerous to breathe. And, at high levels, it displaces oxygen necessary for breathing.

Moldy Smell

Musty, dirty socks, earthy smell indicates growth of mold in your AC. Mold thrives in damp areas that are poorly lit and unfortunately, your AC systems offers that ideal environment. What’s you’re now smelling is the mycotoxins, a metabolic byproduct of mold produced during cooling cycles. Adding a UV filter to your AC system will destroy mold and its spores, preventing further growth. As a preventative measure, to avoid water build up in the system, ensure that the drain pans are properly positioned. Drains that don’t drain properly provide an ideal place for mold growth.

One of the most common indoor air-quality problems is odor emission from ACs. While an odor problem doesn’t necessarily translate to expensive repairs, ignoring the problem will. Most home appliances always send warning signs before things get out of hand- pay attention.
