An air conditioning system is a very critical component in a household. The system controls ventilation, facilitating the continuous flow of fresh air in your home. Over time, the gust of fresh air may be accompanied by odors, which can be very unpleasant. The foul smells can be attributed to several things, and you’ll need to understand them before any corrective measures are taken. This article highlights the reasons for AC smells and possible solutions to the problem.
1. Electrical Hitches
An air conditioning system relies on various electrical components to function, such as the fan and the compressor. In case of an electrical fault, the multiple components’ wiring will heat up and melt, resulting in a foul burning smell. If left unchecked, the odor can result in breathing difficulties for you and your family. In such instances, seeking a seasoned air conditioning expert is essential to determine the root cause of the smell.
2. Accumulation of Dust
If an air conditioning system has not been used for a long time, dust accumulates in the fans, air vents and air compressor system. When switched on in a dusty state, an air conditioning system tends first to burn out the dust. This results in a burning, dusty smell. The process lasts less than an hour before a continuous stream of fresh air comes out of the vents. It’s a good idea to have it checked by an expert before switching it on if you have not used your AC system for a while.
3. Gunpowder Odor
When metal components within the air control system — such as the fan, motor and control circuit board — burn out, a distinct gun powder-like smell is produced. If you smell this, call us immediately. Your AC could suffer irrevocable damage if this odor is left unchecked.
4. Persistent Rotten Egg Smell
The smell of rotten eggs from air conditioning vents is something to take seriously. Natural gas leaks are usually the main culprit, and this gas leak can create a severe fire risk. Even though the gas is odorless, gas supply companies typically add a sulfur scent to natural gas cylinders to make it easy for you to identify any leakages. In high concentrations, natural gas has been found to minimize oxygen flow in the body, resulting in unconsciousness.
The decay of dead rodents in the vents can also result in a rotten egg smell. In such instances, the entire air conditioning system needs to be inspected and cleaned up of any decaying matter.
5. Exhaust Gases
Exhaust fumes from rotating components in an AC system can be very unpleasant. The nature of the fumes usually depends on the kind of power source being used. If left unchecked, the stuffy fumes make it hard to breathe when the system is on.
6. Moldy Smells
An air conditioning system incorporates a system of ducts to transfer fresh air into a building. Due to humidity, it’s common to find water condensing in some portions of the air ducts and vents. Humid conditions provide a favorable environment for the growth of mold and fungus.
As air blows through the fungus, a musty smell comes out of the vents, making the air in a building stale and unpleasant. Moldy odors have been found to trigger allergies, which hamper breathing. It’s advisable to seek the services of a trained professional to detect points where water may be accumulating or leaking into the ducts.
7. Persistent Dusty and Stale Air
This may be a sign that some electric components are not working correctly in your air conditioning system. A change in air quality is also a sign that the AC system may be faulty and requires immediate technical attention.
