However, this is not usually the case. Air-conditioners are intended to control the airflow and keep the temperature cool on hot days.

Depending on the installed aircon unit, it is important to prevent pungent smells as soon as they occur to prevent unsettling and lingering foul smells that emanate from the air con and spread out all over the house or office.

In Singapore, companies that are mandated to carry out any special repairs on aircon systems should be registered with the National Environmental Agency.

Odors are most noticeable in conditions where temperatures are high and the humidity level is also high as well. Scientifically, the presence of heat enables foul smells to permeate through multiple substances, making the smells progressively pronounced.

Most people purposefully overlook this critical and money-saving factor. Air conditioners ought to be serviced at least two times per year. You should simply contact an expert who will visit your home and check the air con for any wear and tear that can cause damages to your unit.

The aircon professional will check the vents and the chambers. Note that a clean air filter should always be installed at all times to avoid the possibility of altering the proper functionality of the aircon.

Besides the guarantee of clean fresh air, the technician will also do a thorough spot check in other areas of the entire unit and clean out or suggest a replacement for worn-out parts. Following this step will ensure that you will not have any foul smells being emitted from your air conditioner.

2. Clean the Air Conditioner Yourself Occasionally or Do it Yourself (DIY)

If you are confident that you want to adopt a DIY (Do it yourself) approach, there is no compelling reason to call an expert. You can utilize a cloth to clear off or scour any dirt from the air con filter. If the smell was due to an accumulation of dirt on the filter, this process will help solve the problem and at no cost to you.

Routinely make sure that your aircon is clean to avoid any obstruction of clean air that is meant to come from a well-functioning unit.

The most effective method to viably clean an air conditioning system by yourself would be to:

Make a Cleaning Arrangement 

As much as you need so much water when decreasing scent from an AC, you need to blend it with a cleaning solution made out of vinegar. Other cleaning solutions are made explicitly for that reason however since you are doing it without anyone else’s help you don’t need to buy any. Simply pour 25% vinegar and 75% water in a large bowl at that point blend well.

  • Before you begin cleaning the unit, ensure that you switch off the power to the air con from the circuit breaker box and unplug it. Carefully clean the necessary compartments with the water and vinegar solution.
  • Locate and open the air con broils. Focus only on the area that has debris and dirt and wipe off appropriately. You may use a toothbrush to take away fine dirt from these regions.
  • When you are finished cleaning the air con broils, you can then begin working on the channel. If there is a foul smell that is coming from the channel, this might be the place where you will lay a lot of emphasis in cleaning to ensure that the foul smell is eliminated with the flame broils and fulfilled, you would now be able to begin the channel.
  • To help you maximize on your DIY efforts, you will need to ensure that you spray the condenser fins with clean fin cleaning brush when the air con is still off. This will help to increase the efficiency of your unit.
  • Replace the panel coverings of the condenser coils and wait a few minutes for the exterior to dry and then switch the power back on to the cooler.

Remember to take precautionary measures not to spray water or cleaner on any electrical control panels that are inside the air con as this may bring on additional problems.

If any of the above steps do not yield the desired results, consider calling a certified aircon technician for aircon servicing to thoroughly check on your unit for any problems. If the problem persists even after the servicing, the contractor may advise you to take on a chemical wash instead.
