How To Make Your Aircon Casing Look Whiter Again

aircon casing

The process of aging deteriorates both function and performance of both living things and non-living things. For aircon units, aging may result in the aircon unit not cooling the room effectively or even having abnormal sounds when the aircon unit is operational.

Aside from performance, aging in aircon units can turn the usually white casing into yellow, which can be a sight for sore eyes even if it doesn’t impede the aircon unit’s performance. Regular aircon servicing can maintain your aircon unit’s function, but regular cleaning will not be able to return your yellow aircon back to white.

Why has my aircon unit casing turned yellow?

Yellowing is a very common occurrence in aging aircon units or even other appliances. But what causes them to turn yellow? The main reason would be oxidation, be it from exposure to UV rays, heat, or even sulfurization from air pollutants.

These would make fundamental changes within the molecular structure of the plastic which eventually results in yellowing. Once the plastic has turned yellow, it is not possible to reverse the process. Therefore, if you wish to avoid the yellowing process, do keep your aircon units away from UV exposure, especially if sunlight enters through a window during the day.

How do I remove yellow stains from my aircon unit casing?

As mentioned above, there is no way to reverse the yellowing process. However, there are ways to make your aircon unit look cleaner and whiter. Firstly, you will have to clean the aircon unit to get rid of any dirt, dust, and grime clinging on.

To do so, carefully dismantle and remove the outer casing of your aircon unit and give it a good rinse. To remove difficult stains, it is recommended that you use a strong surface cleaner to get rid of tough-to-clean dirt.

After getting rid of the dirt and stains, give your aircon unit casing a good wipe down and air it until it is completely dry. Next, you can use a specialized spray to give your aircon unit casing the white coating again as you can see on some DIY cleaning videos. By using this specialized spray, we were able to create a polished white finish on the casing that covers up all the yellowing from before.

Why is it important for an aircon unit to be clean both inside and outside?

Cleaning your aircon unit regularly allows it to perform more efficiently by reducing the stress and pressure that dust and debris build-up usually put on your aircon unit. When air filters get clogged and become dirty, the normal flow of air is impeded thus making your aircon unit work harder than it should.

A professional SG aircon servicing company recommends cleaning or even replacing an air filter often to achieve better air efficiency. In addition, when dust covers your evaporator coil, its ability to absorb heat is impaired, which further reduces efficiency and ability to cool your home.

In a normal household, aircon units use a significantly large chunk of your monthly electrical consumption. On the same note, a dirty aircon unit consumes more power mainly because your aircon unit is forced to work harder raising its operating costs.

Such aircon units in general use anywhere between 5%-25% more electricity. By calling a professional aircon servicing company to clean your aircon unit regularly, you can reduce your aircon unit’s need to work harder and thus shave some dollars off your electricity bill.

Leaving aircon units running in a dirty state will eventually lead to bigger aircon issues or worse a complete failure of your aircon unit. As your aircon unit gathers more dust and dirt, it will become more difficult to clean which may lead to costly replacement of parts.

Additionally, all aircon units are prone to overheating as the evaporator coils are unable to dissipate heat effectively. These aircon issues can be avoided by having your unit regularly cleaned by a professional aircon servicing company.

Furthermore, while in the process of cleaning your aircon unit, a professional aircon servicing company can detect and identify potential aircon issues that your aircon unit may encounter in the future.

This will prevent more expensive repairs, or worse, having to replace your whole aircon unit. While it is true that it will cost you money to hire expert cleaners, it is still far cheaper than the costs of future repairs and replacement.

Your aircon unit does more than just cool your home, it also plays an important role in helping to keep the air circulating inside your home clean and healthy. A dirty aircon unit provides a suitable breeding ground for mold, fungi, bacteria, and germs to thrive.

Whenever you turn on your aircon unit, these particles get blown into the room and contaminate the air, exposing you, your family, and friends to a variety of respiratory infections and triggering asthma attacks.

While performing a DIY method in keeping your aircon unit properly maintained and regularly cleaned provides a lot of benefits. You can reach out to your Singapore aircon installer for assistance when in doubt.

Those listed above are just some of the main reasons why you should consider having a professional aircon servicing company take a look and clean your aircon unit, whether it is about making your aircon unit look new again on the outside or thoroughly cleaning them from the inside.

It’s always a good time to talk about the common issues that aircon units have. This way, you’ll be able to spot if there are problems with your unit or not and prepare for its replacement accordingly.
