6 Bad Smells From Air Conditioners And Their Surprising Causes
The worst odours are foul odours. They can infiltrate your home and make it unpleasant to live in.
If your house smells bad, the source could be your air conditioner. A bad-smelling air conditioner, also known as “dirty sock syndrome,” can ruin your day.
If you turned on your air conditioner this summer and discovered it was emitting a foul odour throughout the house, you may be wondering why.
There are several reasons that may be responsible for your air conditioner’s smell.
A foul odour from an air conditioner can indicate a problem, potentially dangerous problem such as an electrical fault or fire.
So, if you turn on your air conditioner and notice a foul odour coming from the vents, you should look into it.
However, foul odours from your air conditioner can be annoying, and it is time to clean or replace the filter, and you should hire an Aircon Cleaning Company.
It’s also possible that the circuits have burned out, posing a fire risk while heating and cooling your home.
Whatever the cause, you should have air conditioner odours investigated right away.
Here are seven of the most common air conditioner odours, along with their causes:
1. Musty or mouldy odour in air conditioners
If your air conditioner emits a stale or musty odour in your home, it could be due to a system leak. Drip lines, drain pans, and evaporator coils frequently clog and leak. This leaking water can accumulate and provide an ideal breeding environment for mould. Mould and mildew are two of the most common sources of unpleasant odours.
A musty odour, on the other hand, can be caused by a dirty air filter, especially in humid areas. Extra moisture on the filters can cause unpleasant odours; dirty filters can also affect air quality. As a result, we recommend brushing off the dust and washing the filters in soapy water every three months. Anyone can clean a dirty filter. To repair a leak, however, you will need the assistance of a professional.
If mould is found throughout the air conditioning system, you may need to hire a mould removal company.
2. Air conditioner smells of smoke
Air conditioners have numerous components and circuits. Faults can occur, as they do with all electrical devices. A burning odour, for example, indicates that one or more electrical components are on fire. Water damage, overheating, dust buildup, and other factors can all contribute to this.
There may be no need to be concerned if the odour dissipates quickly. However, if the odour persists for more than a few seconds or the unit emits smoke, you should turn it off immediately and contact an HVAC specialist before continuing to use it.
Regular maintenance can reduce the risk of buildup and clogs, so schedule annual maintenance is always a good idea.
3. The air conditioner emits chemical odours.
If your air conditioner emits a chemical-like odour similar to paint thinner or chloroform, it could mean that your system is leaking refrigerant.
Refrigerant gas in reverse-cycle air conditioners treats the air before it is distributed throughout your home.
A chemical odour indicates that refrigerant leaks are causing environmental damage and limiting the performance of your air conditioner.
4. The air conditioner smells like exhaust fumes.
Overworked or unserviced air conditioners can emit an odour similar to car exhaust.
Motors are used in air conditioners. Engines require lubrication. And this is where oils come into play. If the oil leaks or the central unit overheats, the oil can burn and cause unpleasant exhaust odours to enter the home.
If exhaust fumes are not adequately ventilated, they can harm your health. Contact a heating, ventilation, and air conditioning professional to resolve the issue.
5. The smell of fireworks emanates from the air conditioner.
An air conditioner that smells like fireworks or gunpowder could signify a severe problem. The fan motor or circuit board has most likely failed and must be replaced. This can be caused by overheating, water damage, or insufficient voltage on the circuits. You may need to contact an electrician to ensure that your home’s wiring is not damaged by electricity, or you may require a new switchboard.
The smell of burned-out electronics is similar to that of burnt food.
However, the consequences could be far worse. Again, the fumes can cause respiratory issues. As a result, before making any repairs, it is best to turn off the air conditioner and open the windows.
6. The air conditioning smells like rotten eggs.
In Australia, gas is not commonly used in air conditioning.
If you smell rotten eggs and have gas-ducted heating, you must contact a gas specialist immediately because rotten eggs can indicate a gas problem.
In air conditioning, rotten egg odours are usually indicative of something dead.
If you notice a rotten egg or sulphur odour, it is likely that an animal or rodent has died in your system.
Rats, mice, lizards, birds, and opossums have all been observed exploring the interior of a compressor or vent, only to become trapped and die. It only takes a few days for them to emit a distinct odour that cannot be mistaken for anything else.
Contact professional technicians to resolve this issue and determine whether the system’s performance has been impacted.
If you notice any odours in your air conditioner, have it checked by a professional who can recommend a suitable solution. All that is required are repairs or a thorough cleaning. However, it may be time to replace or upgrade the air conditioner if critical circuits are burned out.
Call Aircon Cleaners for an inspection or after-hours emergency service, whatever the reason.
