Different kinds of AC maintenance issues result in different kinds of odors. If you smell something specific, you can immediately determine the cause and inform an AC maintenance serviceman to deal with it immediately.
Here’s a list of some of the most common AC odors and what they could mean:
I smell something musty
A dank, musty smell is a telltale sign of mold around or inside your AC unit. After all, fungus tends to sprout wherever moisture or water stagnates, making your AC’s evaporator coils, drainage line and filters ideal for mold to germinate. Mold also posits a threat to you and your family’s health as breathing in fungal spores could cause allergies and trigger asthma attacks. Replace and clean your AC’s filters regularly and have a professional handle the evaporator and drain pipes as they require disassembling the unit.
I smell rotten eggs
If you pick up on this funk, then it’s a funeral. No really. Small animals like rats or birds find refuge in an AC’s ducts, and those that don’t survive decompose and start stinking up the air. In addition to odor, dead creatures are a source of life-threatening diseases. Couple that with the ventilation system in your unit, and the air in your home may well be poisoned. To deal with this problem immediately, contact a pest control service to remove the animal as well as sanitise the place to kill any disease vectors.
I smell something burning
Burnt things are a setup for great disappointment and frustration. That cake you forgot was in the oven, that shirt you accidentally left the iron on, that AC motor that hadn’t been oiled in ages. While oiling, cleaning and repairs are usually covered in your annual maintenance contract, the AC fan or circuit board might spew smoke and sparks due to fluctuating voltages or faults in the wiring. This causes that burning smell which may cause permanent damage to your AC unit if left unattended to. Have the faulty parts immediately repaired or replaced, or else you might have to fork out a considerable amount of money for an entirely new AC.
I smell toilets
Sewage smells emanating from your AC could mean trouble for more than just the unit. Blocked sewage pipes near or connected to your AC’s drainage ductworks can cause methane gas to leak into your unit. While methane gas is non-toxic, it’s an asphyxiant, meaning it strains breathing. And when it accumulates, it can turn your house into a bomb ready to explode as it is a highly flammable compound. Report blocked sewage drains to your building manager to resolve the issue as soon as possible and have an AC maintenance service redirect the duct lines.
I smell gas
If your nose picks up on gas, you’ve got yourself a leak. ACs are outfitted with coolants that are responsible for chilling the air and need to be recharged from time to time. Often wear in the unit or rust may cause the tank to leak and this can also affect cooling other than spread odors. Contact a repair service company to replace damaged components and recharge the gas. If your AC is fairly old, then consider replacing the entire unit as it’ll likely give you more trouble later on.
