Revitalise Your Aircon: When to Opt for a Chemical Wash or Overhaul

Is your aircon underperforming no matter how often you service it? Hard water deposits, grime and sanitization issues may call for periodic chemical washing or overhauls. This guide will walk through signs indicating it’s time to schedule these deeper cleanings along with an overview of the processes.

Restore your AC to top cooling performance with a thorough aircon chemical wash or overhaul. Bid farewell to lacklustre airflow, strange odours and mould – and say hello to an aircon that keeps your home crisp and comfortable.

#1 – What is an Aircon Chemical Wash?

An aircon chemical wash utilises strong cleaning solutions to deep clean the entire system and remove accumulated buildup. Technicians access internal components and wash them down with specialised chemicals like coil cleaners, degreasers and sanitisers. The solutions dissolve stubborn deposits like sediment, dirt, oil and grime that regular servicing doesn’t address. Chemical washing revitalises cooling performance inhibited by accumulated gunk. The process takes 2-3 hours and should be done every 2-3 years.

#2 – When to Schedule a Chemical Wash

Consider scheduling a chemical wash if your AC exhibits these symptoms:

• Poor airflow and limited cooling even after servicing
• Persistent odd odours emitting from indoor vents
• Visible dirt or grime buildup on vents and registers
• Frequent clogging of the condensate drain line
• Black substance accumulating on cooling coils
• Significant dust or debris blowout when turning on

Don’t disregard these signs – they indicate a deeper cleaning is needed for optimal operation. A chemical wash restores cooling capabilities and eliminates unpleasant odours.

#3 – The Chemical Wash Process

Chemical washing involves these key steps:

• Coils are pre-treated with a degreasing solution
• Condensate pans are scrubbed and washed out
• Disinfectants are misted onto coils and ducts
• Detergents dissolve mineral deposits on coils
• Rust inhibitors are applied to metal components
• Sanitisers eliminate bacteria and odours
• Coils are rinsed thoroughly to remove residues
• Drain lines are flushed with high-pressure water

Proper PPE is used to safely handle chemicals. The result is an aircon free of accumulated gunk hindering performance.

#4 – What is an Aircon Overhaul?

While chemical washes focus on deep cleaning, an aircon chemical overhaul is an intensive repair restoration bringing the system to good-as-new condition. This involves a full disassembly and inspection of all components. Worn or damaged parts like compressors, capacitors, valves and bearings are replaced. The overhaul addresses mechanical issues beyond cleaning alone. It should be done every 5-10 years based on usage.

#5 – When to Schedule an Overhaul

Consider a major overhaul when:

• The age of the aircon exceeds 10 years
• Frequent breakdowns occur and repairs no longer help
• Electricity bills are excessively high
• The system makes loud, grinding noises
• Refrigerant leaks faster even after recharging
• Major problems like motor failure occur

If your ageing aircon suffers from multiple issues requiring frequent repairs, it indicates components are wearing out. Continuing to patch one problem after another is not cost-effective in the long run. A full overhaul would comprehensively address underlying mechanical wear and tear to restore the system.

#6 – The Overhaul Process

Aircon overhauls involve:

• Full disassembly and inspection of individual components
• Replacing any damaged or worn-out components
• Retrofitting parts to boost energy efficiency
• Repairing and realigning motors and compressors
• Upgrading to improved refrigerant types if needed
• Extensive leak testing and refrigerant line repairs
• Re-wiring of electrical connections as needed
• Comprehensive testing ensures all components function optimally

The overhaul is an intensive process requiring specialised skills and reputable parts to return the aircon to proper working order. Only qualified technicians should undertake the complex disassembly, inspection, repair and reassembly required. Rushing through an overhaul often leads to mistakes and improper repairs.
