Professional Aircon Installation Across Singapore
Installing an aircon is not just about mounting a unit on the wall. It requires precise piping, proper electrical connections, correct gas charging, and careful placement to maximise cooling efficiency. A poorly installed aircon leads to frequent breakdowns, water leaks, high electricity bills, and shortened equipment life.
Billy Aircon provides end-to-end aircon installation services for HDB flats, condos, and landed homes across Singapore. Our installation team handles everything — from the initial site survey to final testing — so you get a system that runs quietly, cools efficiently, and lasts for years.
We install all major brands including Daikin, Mitsubishi Electric, Panasonic, Midea, Samsung, LG, Fujitsu, and Toshiba. Whether you are fitting out a new home, replacing an old system, or adding units to existing rooms, Billy Aircon delivers professional results every time.
What Our Installation Service Includes
Every Billy Aircon installation comes with a comprehensive package that covers all essential components.
Trunking and Piping
We use quality PVC trunking to neatly conceal copper piping and drainage hoses along your walls and ceiling. Trunking keeps your installation looking clean and protects the pipes from accidental damage. Our standard installations include up to 10 feet of trunking per unit, with additional lengths quoted separately.
Copper piping connects your indoor fan coil unit to the outdoor condenser. We use the correct pipe diameter for your system’s BTU rating to ensure optimal refrigerant flow. All piping joints are flared, tightened to specification, and pressure-tested before gas charging.
Electrical Wiring and Isolator Switch
Each aircon unit requires a dedicated electrical circuit with the correct amperage. Billy Aircon installs the isolator switch, runs the power cable from your distribution board (DB box) to the indoor unit, and connects the control wiring between indoor and outdoor units. All electrical work follows Singapore’s BCA and EMA regulations.
Outdoor Condenser Installation
The outdoor condenser is mounted on heavy-duty brackets secured to your exterior wall or placed on a concrete ledge. Proper condenser placement ensures adequate airflow for heat dissipation. Our technicians assess the best location based on your property layout, considering factors like direct sunlight exposure, drainage access, and noise levels.
Drainage Setup
We install a proper drainage system to channel condensation water away from your aircon unit. For HDB and condo installations, we connect the drain hose to your nearest floor trap or external drainage point. Correct drainage setup prevents the common problem of aircon leaking water.
Installation for Different Property Types
HDB Flat Installation
HDB flats in Singapore have specific requirements for aircon installation. Most HDB units have designated aircon ledges on the exterior wall for condenser placement. Billy Aircon works within HDB guidelines, ensuring proper bracket mounting and drainage to the approved discharge points.
For BTO flats, we coordinate with your renovation contractor to ensure trunking routes are planned before ceiling and wall finishes are applied. This results in a cleaner installation with minimal visible trunking.
Common HDB configurations we install include system 2 (1 outdoor + 2 indoor units), system 3 (1 outdoor + 3 indoor units), and system 4 (1 outdoor + 4 indoor units).
Condo Installation
Condo installations often involve longer piping runs and specific management requirements. Many condos require approval from the MCST before installation work can begin. Billy Aircon assists with the necessary paperwork and ensures our work complies with your condo’s building regulations.
We handle installations for both new and resale condos. For new units, we can work with your interior designer to plan concealed piping routes behind false ceilings.
Landed Property Installation
Landed homes offer more flexibility in condenser placement but may require longer piping runs and additional electrical work. Billy Aircon provides free site surveys for landed property installations to assess the optimal setup for multi-storey homes.
For large landed homes, we recommend multi-split or VRV/VRF systems that connect multiple indoor units to a single outdoor condenser. This saves space and reduces noise compared to having individual condensers for each unit.

How to Choose the Right BTU for Your Room
Choosing the correct BTU capacity is critical for efficient cooling. An undersized unit struggles to cool the room, while an oversized unit short-cycles, wastes energy, and creates uneven temperatures.
General BTU Guidelines for Singapore:
| Room Size | Recommended BTU |
|---|---|
| Small bedroom (up to 120 sq ft) | 9,000 BTU |
| Master bedroom (120–180 sq ft) | 12,000 BTU |
| Living room (180–300 sq ft) | 18,000 BTU |
| Large living room (300–450 sq ft) | 24,000 BTU |
These figures account for Singapore’s tropical climate, typical ceiling heights of 2.6 to 2.8 metres, and average insulation levels. Rooms with large windows facing west, high ceilings, or heat-generating equipment may need higher capacity.

Step 3: Scheduling Once you confirm the quote, we schedule your installation at a time convenient for you. Same-week installations are available for standard setups.
Step 4: Installation Day Our team arrives on time with all necessary materials and tools. A standard single-unit installation takes 2 to 3 hours. Multi-unit systems take 4 to 6 hours depending on complexity.
Step 5: Testing and Handover After installation, we run your new aircon system for at least 15 minutes, checking refrigerant pressure, airflow temperature, drainage, and electrical connections. We walk you through the remote control functions and basic maintenance tips.
Post-Installation Support
Every Billy Aircon installation comes with a 90-day workmanship warranty covering any installation-related issues such as gas leaks at pipe joints, drainage problems, or electrical faults. This is in addition to the manufacturer’s equipment warranty.
After installation, keep your aircon running efficiently with regular servicing. We recommend scheduling your first general service 3 months after installation, then every quarter thereafter. If you notice your aircon is not cold or suspect a refrigerant issue, a gas top up may be needed.
Frequently Asked Questions
How much does aircon installation cost in Singapore?
Installation costs vary based on the number of units, piping length, trunking requirements, and property type. Contact Billy Aircon at +65 9456 0875 for a personalised quote.
Do you supply the aircon units or install customer-purchased units?
We do both. You can purchase units through us at competitive prices, or we can install units you have purchased separately. Either way, our installation quality and warranty remain the same.
How long does installation take?
A single-unit installation typically takes 2 to 3 hours. A system 4 (4 indoor units) takes about 5 to 6 hours. We complete most residential installations within a single day.
Do I need to be home during installation?
Yes, we recommend having someone present during the installation for access and to approve final unit placement. Our team keeps the work area clean and disposes of all packaging materials.
Can you install aircon in a room without an existing point?
Yes. We can run new piping and electrical wiring to rooms that do not have existing aircon provisions. This involves additional trunking and possibly hacking work, which we quote separately after a site survey.
