In the event that the chemical wash is insufficient to clean the system thoroughly, professionals may recommend an air conditioning chemical overhaul.
The professional will then be able to determine whether your air conditioning unit requires a complete overhaul or just a simple chemical cleansing. Professionals prescribe a chemical wash or overhaul at least once a year to maintain the air conditioner’s optimal performance.
The components of an air conditioner are disassembled and cleaned during maintenance. Certain components are either being restored or replaced. (varying on the damage to your aircon).
When do you need an aircon overhaul?
Here are some instances in which a revision would be required:
- When the intakes become obstructed with dust particles or grime
- Water leakage caused by clogging of sewer pipelines
- Destruction of evaporator coils
- Worn-out fan components
- Defective or compromised air purifiers
After receiving a chemical overhaul, you can expect your unit to be as good as new.
The approximate cost of overhauling your air conditioner is between $130 and $180 SGD per unit.
It is always a good idea to have your air conditioner cleaned and maintained regularly, as this will not only prevent you from incurring expensive air conditioning repair costs but will also extend the life of your unit.
What happens during an air conditioning overhaul?
These are the typical chemical maintenance tasks for air conditioners:
- Lubricating a fan’s bearing to reduce noise and boost efficacy.
- Checking and monitoring the unit’s thermostats and controls.
- Chemically cleaning the pipes, blower wheel, and discharge basins.
- Removes grit and debris from the fan evaporator coil, increasing efficiency.
- Replaces defective bearings and eradicates operational disturbance.
What differentiates a chemical wash from a chemical overhaul?
While both processes sanitise your air conditioner, a chemical wash and a chemical overhaul are distinct. An air conditioner chemical wash will thoroughly clean your air filters and coils. This prevents the growth of harmful substances, such as mould, that would harm your health.
In contrast, a chemical overhaul is more comprehensive than a chemical wash. For example, it helps to ensure that the air conditioning ducts are clean, which facilitates better airflow for your air conditioner and improves its performance and efficacy.
An air conditioning chemical wash is recommended every six months, while a chemical overhaul should be performed annually. Suppose your air conditioner is not operating as efficiently as you would like. In that case, you can always consult a professional to determine if you need to increase the frequency of chemical overhauls.
In conclusion, an air conditioning chemical wash ensures that your air conditioning unit is free of contaminants such as fungi so that it can produce higher-quality air. A chemical overhaul, on the other hand, improves air conditioning efficacy by ensuring that worn-out components are replaced. Therefore, to improve the maintenance and longevity of your air conditioning unit, you should perform both a chemical wash and a chemical overhaul.
