What is Aircon Chemical Wash?

An aircon chemical wash involves using chemical solutions to clean an air conditioning unit’s fan-coil and internal components. This process helps remove built-up dirt, oil, and dust that can cause your air conditioner to work harder than it needs to.

We make sure every part of the system gets attention—this includes the evaporator coils, which play a key role in cooling your home efficiently. During this deep clean, we also check parts like the circuit breaker and refrigerant levels to ensure everything works perfectly.

Our goal is to improve your air conditioner’s performance and prevent common issues such as poor cooling or unusual noises from arising.

Potential Risks of Chemical Wash

Chemical washing can harm your air conditioning system. It’s not the best for the environment either. Using strong chemicals might clean out dirt, but it also risks leaving wet areas around your unit.

These leftover liquids can hurt parts inside your air conditioner, like the fan coil and back tray. The process costs $80 per unit in Singapore, which adds up if you have multiple units to clean.

Using too much pressure during a chemical wash may cause corrosion damage to coils. This makes your aircon less efficient and could lead to bigger problems later on. Plus, if not done right, chemicals might reach electrical components inside your HVAC system.

This is risky because it could break these parts down over time or even cause short-circuiting issues. We at iCare Air understand these risks well and always advise considering them before choosing a chemical wash for your cooling units.

Corrosion of Fan Coil Unit

We know that a chemical wash can lead to corrosion of the fan coil unit in air conditioners. This happens when a strong jet of water moves dirt onto the fan coil during cleaning, causing debris buildup and later corrosion.

Often, a normal chemical wash isn’t enough to remove all the grime stuck between the coils. Even if your service is covered under warranty, this process might still harm the motherboard or other electrical components inside your HVAC unit.

So, we make sure our team at iCare Aircon uses methods that avoid such damage and keep your air conditioning system running smoothly.

Incomplete Cleaning of Fan Coil and Back Tray

Our team often sees an issue where the fan coil doesn’t get fully cleaned. Technicians skip taking it apart fully, so they miss dirty spots. The V-shaped evaporator coil traps dirt and water in the back tray.

This area is tough to reach with just a chemical wash. Dirt and water build up there can cause leaks and harm electrical parts.

This kind of neglect leads to bigger aircon problems down the line. Without dismantling every part, technicians can’t clean all areas well. Accumulated dirty water in these hidden sections risks damaging crucial components like circuit breakers and printed circuit boards, vital for smooth operation.

Such oversight doesn’t just affect performance; it threatens your system’s health too.

Potential Harm to Electrical Components

Chemical washes can put your air conditioning system’s electrical parts at risk. If water from the back tray seeps into the fan coil, it may damage the motherboard and other vital components.

This means you could be without cool air for days. A job not done right might even cause compressor failure. Such issues need repairs, leaving you in discomfort for a while. We make sure to handle every component with care to prevent these problems.

Alternatives to Chemical Wash

Steam cleaning and regular upkeep are good choices instead of chemical wash. They keep your aircon in top shape without the harsh effects. Want to know more about these options? Keep reading, and we’ll show you how they work and why they might be better for your cooling system at home.

Steam Cleaning

We use high-temperature steam to clean air conditioning units. This method is more environmentally friendly and also more affordable than traditional chemical washes. It enhances air quality by removing dirt and mildew without leaving any harmful chemicals or residue behind.

The process involves heating water to produce steam, which then evaporates quickly, taking condensation with it.

Our team at iCare Aircon recommends steam cleaning for both central air conditioning systems and room air conditioners. We ensure that the procedure improves climate control within your home while being gentle on the components of your unit like the ductwork, fan coil, and air filters.

Hiring qualified professionals like us guarantees that your system benefits from this effective maintenance technique without risking damage to sensitive parts such as the electrical components or causing a refrigerant leak.

By opting for steam cleaning, you’re choosing an affordable solution that contributes to better energy saving and extends the lifespan of your device by ensuring routine maintenance is carried out correctly.

Regular Maintenance

Keeping your air conditioner in top shape is crucial. We ensure this by conducting regular maintenance. This means we check the dirty air filter, clean it or replace it if needed. Cleaning the condenser coil and checking all electrical components are also part of our routine checks at iCare Aircon.

These steps help your central air conditioner run smoothly, without short cycling or other issues.

We don’t just stop there. Vacuuming out the outdoor unit, ensuring the power supply is consistent, and inspecting for any leaks around your system form an integral part of our service.

By identifying problems early, we prevent costly repairs later on. Regular maintenance makes sure that your air-conditioner works efficiently, saving you money on energy costs and extending its lifespan significantly.

Is Chemical Wash Ever Necessary?

Yes, a chemical wash is necessary in certain situations. For aircon not cooling, leaking water, or emitting bad smells, we recommend it. This approach helps remove dust and harmful bacteria effectively when regular servicing falls short.

At iCare Aircon, we suggest considering an aircon chemical overhaul for deeper issues. Prices in Singapore start at $80 per unit for this service.
