Aircon Overhaul
An aircon overhaul involves a thorough deep clean and an expert inspection of the constituent parts of the air conditioning system. It entails a disassembly of the air conditioning unit which allows for both cleaning and checking for worn or damaged parts. An AC overhaul can be a mix of aircon general servicing, aircon chemical wash, and aircon repair. A chemical overhaul, in particular, serves as the next stage to an aircon chemical wash.
When Does Your Air Conditioner Need an Overhaul?
If you notice that your AC is not cooling your room as efficiently as it used to, then it might be time to consider having an aircon overhaul. The presence of weird noises, strange smells, or water leaks is also hinting at various underlying issues in the air conditioning unit, all of which can be addressed with a comprehensive overhaul. HVAC professionals will dismantle the air conditioner for cleaning, while simultaneously assessing each disassembled part for damage.
There are cases where a service technician, during a routine overhaul, uncovers something that might necessitate a full chemical overhaul. In general, these are the issues that call for a chemical overhaul:
- Congested aircon vents
- Damage to the evaporator coils
- Malfunctioning fan bearings
What Are the Benefits of an Aircon Overhaul?
An aircon overhaul is usually performed by a specialist who is trained to look at disassembled aircon parts, identify potential risks and damages, assess how far along any fledgling defect might be, and advise on either repair or replacement of parts–whichever solution is more cost effective at the moment. The benefit of this service can’t be understated because it is a unique opportunity to prevent small maintenance issues from escalating into bigger ones which require expensive fixes.
The meticulous clean-up and maintenance involved in an aircon overhaul can help you save money, too. With a well-maintained air conditioning unit running in optimal conditions, you can maximize the air conditioner’s energy efficiency capabilities which in turn help reduce electricity consumption.
What Happens During a Chemical Overhaul on the Indoor AC Unit?
The process depends on the scope of work offered by the aircon service provider, but in general, a chemical overhaul on the indoor sub-unit of a split-type air conditioner proceeds as follows:
The indoor fan coil unit is taken down from the wall and carefully dismantled. The electrical circuit board or PCB is separated from the disassembled parts. So is the evaporator coil, fan motor, fan blower, and drain pan.
The gaps on the evaporator coil are taped up to protect the sensitive interior areas from the chemical solution that will be injected to clean the outer parts.
A dry brush is used to gently clean the indoor PCB and fan motor, after which the components will be inspected for burnt marks and corroded terminals.
The taped-up evaporator coil, fan coil hatch, fan coil body, and fan blower will be subjected to a chemical wash and then flushed with water. The chemical solution will react with the water, resulting in a thoroughly cleaned and disinfected air conditioner.
The dismantled parts are then re-assembled, and the air conditioner is re-installed back into the wall where it is to be mounted.
Frequently Asked Questions (FAQs) – Aircon Overhaul
An aircon overhaul is a comprehensive servicing process that involves a complete inspection, deep cleaning, and repair of your air conditioning system. It includes dismantling major components, cleaning or replacing parts, and reassembling the unit to restore it to optimal condition.
Regular servicing focuses on basic maintenance tasks like cleaning filters, coils, and drainage pipes, while an aircon overhaul involves a thorough inspection, deep cleaning, and repair of all major components, including the fan coil, evaporator coil, condenser, and electrical parts. It’s more extensive and is recommended for older or poorly maintained units.
You should consider an overhaul if:
- Your aircon is old and hasn’t been serviced regularly.
- You notice persistent issues like poor cooling, strange noises, or water leakage.
- Your aircon requires frequent repairs.
- You want to extend the lifespan of your unit before considering a replacement.
An overhaul is typically recommended every 2-3 years, depending on usage and maintenance history. Regular servicing can delay the need for an overhaul, but older units may require more frequent overhauls.
An overhaul offers several benefits:
- Improved cooling performance. Restores your aircon’s efficiency and cooling capacity.
- Better air quality. Removes mold, bacteria, and dust buildup for cleaner air.
- Energy efficiency. A well-maintained aircon consumes less energy, reducing electricity bills.
- Extended lifespan. Prevents major breakdowns and prolongs the life of your unit.
