A common aircon problem that homeowners experience at least once would be the aircon releasing odour. Although this is a common problem, it deserves immediate attention. To prevent the aircon odor from worsening and causing other aircon issues, you should get it inspected as soon as possible. By hiring professional aircon services, you will be quickly offered the best solution and know why your aircon is smelly. Some aircon services that you can consider hiring include aircon servicing, aircon repair, aircon installation, and other aircon services.
If you want to tackle the smelly aircon issue on your own, you indeed can give it a try, and all you need to do is follow the steps given below:
1.Remove your aircon’s casing
The first thing you need to do when your aircon smells terrible is to remove your aircon unit’s outer case. If you have a smaller unit, you can easily lift the outer case to expose the fan, compressor, and aircon fan coils. In case you have a bigger unit, you will need to loosen the case to access the inner aircon parts easily. While doing so, be careful to avoid bending the metal fins as they are more fragile.
In addition, if your HDB aircon installation was done as a window unit, you need to be extra careful. Since the window unit consists of many screws, you should draw a diagram to remember what snaps and screws go to their respective panels so that you can easily reassemble your aircon later if you are going to do your own aircon servicing. If you are not too sure that you will do it correctly, you can instead hire professional aircon services.
2. Closely inspect your aircon parts
To understand the smelly aircon problem, you now need to use a flashlight and carefully inspect the inner components of your aircon unit. Check if there is a growth of mold or mildew caused by lack of aircon cleaning, or if there is any decaying vegetation or any dead animals that caused the bad aircon odour.
3.Start cleaning your aircon unit
To start off, you need to move your dismantled aircon unit for aircon chemical wash, such as your bathroom. Next, with the help of compressed air, get rid of any debris and dirt that may have accumulated in your aircon unit. Ensure that the compressed air pressure is not too strong, or else the inner parts can get damaged.
Next, take a damp cloth and gently wipe down your unit’s inner components and eliminate any remaining debris or dirt. However, if you feel that your are not capable of cleaning your aircon properly, you can hire professionals for professional aircon washing instead of performing DIY aircon cleaning.
4.Clean the drain line
To eliminate the smelly aircon issue, the next thing you need to do is to remove your aircon unit’s drain line. Now, flush the line using hot water and bleach or distilled white vinegar. This will help kill any mildew or mold that may have developed in the drain line. You can then wash your aircon with plain water and let it dry fully before you reattach it.
5.Clean the ventilation area
The aircon vent area also needs to be sprayed using bleach and water solution. To improve the effectiveness, soak your aircon vent thoroughly with the solution, just like how a professional aircon servicing is done. In addition, the aircon fans should be fully soaked with the solution while being turned on gently. Allow this to remain for some time, and then wash off the aircon chemicals using plain water until the bleach solution is removed entirely.
6.Clean the drain pan
Every inverter or non-inverter aircon has a drain pan that accumulates dirt, causing a smelly aircon. Locate your aircon drain pan and detach it from your aircon. You will need to first wash it using soapy, hot water. Next, rinse it using white undiluted distilled vinegar or diluted bleach solution. Once the aircon drain pan has been washed, leave it to dry completely.
7.Replace the air filters
Air filters get trapped with dust and debris, causing musty odour and aircon not cold issue. To solve this, locate the air filters and replace them with brand new ones. If your aircon unit comes with reusable filters, you need to clean your aircon filter with a diluted bleach solution (1 part bleach and ten parts water) or simply with hot soapy water. Carefully check if your old aircon air filter has mold or mildew that may have caused your aircon smelly issue.
8.Dry your aircon then reassemble
Once you have figured out why your aircon smells bad and have followed all the steps shared above to clean it, you now need to let your aircon unit air dry completely. If your aircon does not dry properly, it may cause other aircon issues. The drying process can take at least a few hours. Once your aircon components are completely dry, you will need to reassemble the various parts together.
