AIRCON COMPARISONS
Side-by-side aircon comparisons for Singapore. Chemical wash vs gentle steam wash, inverter vs non-inverter, repair vs replace and more.
Not sure which option suits your home or budget? These comparisons explain the real differences so you can choose confidently.
Chemical Wash vs Gentle Steam Wash
- Chemical wash: deep cleaning with alkaline solution to remove mould, grease and bacteria. Best for yearly deep maintenance.
- Gentle steam wash: high-temperature steam sanitises without harsh chemicals. Ideal for sensitive households and regular refresh cleans.
- Both restore cooling efficiency and improve indoor air quality when done by a trained technician.
General Servicing vs Chemical Overhaul
- General servicing: filter wash, coil wipe, drain check and gas pressure test. Done every 3 months.
- Chemical overhaul: full unit disassembly and soak-cleaning of coils, blower and drain pan. Done once every 1-2 years.
- Overhauls fix persistent odours, leaks and weak airflow that general servicing cannot.
Inverter vs Non-Inverter
- Inverter: quieter, more energy-efficient, better temperature stability. Higher upfront cost.
- Non-inverter: lower purchase price, louder on full blast, higher long-term electricity cost.
- For daily cooling, inverter systems usually pay back the difference in utility savings.
System 2 vs System 3 vs System 4
- System 2: one outdoor condenser with two indoor units. Best for compact homes.
- System 3: three indoor units. Common for 3-room flats and 2-bedroom condos.
- System 4: four indoor units. Popular for larger HDBs and family condos.
- Adding more indoor units than you need increases purchase and running costs.
Repair vs Replacement
- Repair makes sense when the unit is under 8 years old and the fault is isolated (gas, capacitor, fan motor).
- Replacement is smarter if the compressor is failing, the unit is over 10 years old or repair costs exceed half the price of a new system.
- Uncle 7 Aircon provides honest advice and quotes for both options.
