Aircon Installation Singapore
Professional residential and commercial aircon installation for HDB, condo, and landed properties across Singapore.
Professional Aircon Installation in Singapore
Billy Aircon provides professional aircon installation in Singapore for all property types — HDB flats, condominiums, and landed houses. Whether you are replacing an old system or installing aircon in a new home, our experienced technicians handle everything from site survey to final testing.
We work with all major brands including Daikin, Mitsubishi Electric, LG, Panasonic, Fujitsu, and Toshiba. Our team can advise you on the right system type and BTU capacity for your space, taking into account room size, sun exposure, and the number of occupants.
Types of Aircon Systems We Install
Split System (System 1)
A single indoor unit paired with one outdoor compressor. Ideal for individual rooms in HDB flats or condos.
Multi-Split System (System 2, 3, 4)
Multiple indoor units connected to a single outdoor compressor. The most popular choice for Singapore homes — a System 3 covers a typical 4-room HDB flat with aircon in every bedroom and the living room.
Inverter vs Non-Inverter
Modern inverter systems adjust compressor speed to maintain temperature, using 30-50% less electricity than non-inverter units. We recommend R32 inverter systems for new installations due to their energy efficiency and lower environmental impact.
What Our Installation Includes
Every installation by Billy Aircon includes:
- Refrigerant piping — high-quality insulated copper pipes between indoor and outdoor units
- Condensate drain — proper drainage setup to prevent water leaks
- Trunking — neat PVC trunking to conceal piping along walls and ceilings
- Electrical connections — connection to your home’s electrical supply with isolator switch
- Vacuum testing — the system is evacuated using a vacuum pump to remove moisture before charging
- R32 or R410A gas charging — the correct refrigerant is charged to manufacturer specifications
- System testing — full performance test to verify cooling output and drainage
HDB vs Condo vs Landed Installation
| Property Type | Typical System | Key Considerations |

| HDB 4-Room | System 3 | Piping length to ledge, ceiling height |
| HDB 5-Room | System 3-4 | Multiple piping runs, electrical load |
| Condo | System 2-4 | Building regulations, aircon ledge design |
| Landed | System 4+ | Multiple outdoor units, longer pipe runs |
