Why Your AC Smells Awful

When an air conditioner works in a perfect environment and receives regular maintenance, it’s supposed to make you feel comfortably relaxed. However, a neglected AC does a poor job not only on the cooling part, but it also creates an awful smell. There are several reasons for a cooling system to release bad odors, depending on the situation.

Moldy Smell

It is quite common for HVAC systems to have a smell like mildew or mold because of the condensation that takes place as the unit is running. When the moisture doesn’t drain properly, it can get into the ducts, causing mold development. Mold and mildew will be moved through your indoor air once it has settled in your AC system. Other contaminants in your air conditioner will do the same if left unattended. 

The easiest way to get rid of this smell is to locate the mold buildup and clean it thoroughly. If you find this a little too challenging, your preferred HVAC contractor can do it for you.

Rotten Egg Smell

An AC that produces a rotten egg smell shouldn’t be ignored. This problem can be caused by different things, including a decomposing animal within the ductwork. Rodents and birds have their ways of getting into your home, and if they die and decompose, they will unleash a horrendous smell. When you turn the air conditioning on, it will circulate that smell throughout your home. 

You have to spot and eliminate the dead animal as soon as possible to get rid of the putrid odor. If it isn’t an animal causing this kind of stench, there is likely a potentially deadly natural gas leak in your home.

If you smell rotten eggs coming from your AC, be sure to open all the windows immediately and get out of the house. Call your gas company to deal with the leak and contact a qualified HVAC professional to inspect your cooling system.

Exhaust Fumes Smell

Even if your AC is not gas-powered, it is still possible for the system to release exhaust fumes from some of its essential parts. Not only is this smell dreadful, but it also poses a danger to your health. Since cooling systems run on electricity and not fossil fuels, the exhaust is a warning sign that there is a leak in the motor or other components. For safety reasons, it is best to have a qualified technician inspect the cause of the problem and perform the necessary repairs.

To avoid a dangerous situation, call an HVAC professional to assess your system. Burning oil and other fluids can release substantial amounts of toxic gases. These particulates can be hazardous to your health, depleting oxygen, and resulting in various health problems.

Electrical Odors

If you notice that your AC smells like an overheating machine, chances are: it’s overheating! Please do not ignore this issue as it can pose a considerable risk to your safety. The first thing to do is turn off the unit before attempting to find the cause. Check your air filter and see if it is congested. A dirty filter restricts airflow and overheats the electric resistance heaters. 

However, if the filter is not the cause, it could indicate a problem with the AC’s electrical system. For your safety, have a technician inspect the unit and make the necessary repairs.
