HDB aircon installation fee is pretty standard. However, for condos and landed properties, things are not as simple and straightforward. So let’s take a look at aircon installation for the different types of residential properties.
Aircon installation in HDB units
Regarding HDB aircon installations guideline, there are a few things to keep in mind, and this is assuming you are also installing a new set of pipes along with the air conditioner. First, make sure that the aircon bracket size is adequate. Second, confirm if you have an electrical power point with the correct wattage rating. Lastly, check if your unit has any false ceiling or built-in cabinetry. These two features in your home can obstruct the pathways and routing channels of the aircon pipework.
Condo Aircon installation
For condominium aircon installations, apply for a permit first. You will likely be asked to put down a deposit with your building management for this installation. Establish whether you can reuse your existing aircon piping. We have a handy “how to know if your aircon pipe can be reused” guide that can help you with this. If it can still be reused, then the installation is the same across all types of properties. Just look at the existing model number of your aircon to determine the BTU needed for each room, and then contact us to help you make a great shortlist of aircon models that are well within your budget.
For the installation of new aircon piping, we will determine the price based on the length of piping needed. It also depends on how many ceiling holes we have to open. Therefore, a site visit by a professional is needed as the difficulty of installation is always factored into the installation cost. Furthermore, we likely need more manpower as most condominium managements only allow aircon installation during a specified and limited timeframe.
If you reside in a resale condo, the pricing might be higher because the installation will be more labor intensive. There might be a need to hack certain areas of your walls or below your tiles to lay out water pipes for your air conditioning unit.
Aircon Installation on Landed Properties
Aircon installation with piping in landed properties is similar to that in a condominium. It will be dependent on the length of the copper pipe and the number of ceiling holes to patch. Nonetheless, for many of the landed properties, it is more complicated as the piping goes through many of the integral structures such as columns. Or, they might be hidden inside the walls. Hence, it is absolutely necessary to arrange for a site visit before the actual aircon installation.
Aircon Installation in Commercial Units/ Office
Due to the complex nature of aircon installations in commercial places, we will ask you to send us first a floor plan of your unit/retail shop/office. A follow-up site visit will be conducted to figure out where to situate the pipes. We also have to determine the correct amount of BTU required for each room, as well as other factors such as sun location, devices that emit heat such as commercial photocopying machines, etc.

Through our aircon installation guide, you can learn about the different types of air conditioners. Knowing which aircon type and configuration is best suited for your space and cooling needs can help you make an informed purchase decision.
Casement Air-conditioner
This type of air conditioner is rectangular in shape. It is oriented vertically and installed on a bracket that is mounted on the window. The window has to open out to the outdoors because the hot air from the compressor needs to be dispelled outwards. A casement aircon is usually a non-inverter unit. The advantage of a casement aircon is that it is generally easy to install, while its drawback is a relatively noisy operation because the compressor is not separate from the indoor fan coil unit.
Window Air-conditioner
This type of AC is mounted on a metal bracket and is usually fixed below the window. Also, it is usually non-inverter-based. In Singapore, the only brands currently producing this type of air conditioner are Europace and LG.
Multi-Split Air-Conditioner
Mitsubishi, Daikin , Panasonic , Midea
This is the most common type of aircon in Singapore. It’s divided into two parts: an outdoor unit and a single or multiple indoor units. The aircon compressor is located in the outdoor unit and the refrigerant travels via the copper pipes to the indoor unit, removing hot air from your room and reducing the temperature to your desired level.
Ceiling Cassette Unit
Mitsubishi, Daikin , Panasonic , Midea
Similar to a multi split air conditioning system, a ceiling cassette aircon has two parts: a ceiling cassette installed indoors and a compressor situated in the outdoor unit. A ceiling cassette aircon unit has 4 flaps which facilitate the even distribution of cool air. Unfortunately, it cannot be installed in a HDB flat. Only certain condominiums permit this form of aircon. The ceiling cassette is more suitable for commercial spaces such as offices, warehouses, and retail shops.
Aircon BTU Calculation and What Kind of System Should I Be Getting ?
For HDB, the BTU size is pretty standard. 9000 BTU for rooms. For living rooms, it depends on the size. A 3,4 or 5-room flat has different sizes and the BTU varies according to number of rooms. For landed properties and condominiums, we suggest you refer to the existing BTU you are currently using. If you need to know more about aircon BTU calculations, click the blue link above.
If you wish to install one air conditioner for each of the three bedrooms in your HDB unit, just opt to install a system 3 aircon instead. Alternatively, you can install an aircon only in the living room of your HDB flat. There are HDB owners, however, who are hoping to install a system 5 aircon.
Should I be getting aircon system 4 or 3+ 1?
It depends on whether you need all of the Aircon to be cold when you turn on all together. If that is so, you will need system 3 + 1. However, it might be subjected to constraints by HDB. If you have still have aircon installation questions on this, check out the link above.
Are we allowed to buy system 5 Aircon for HDB?
It depends on whether your hdb is upgraded with the higher electrical loading. Furthermore not all of the brands of system 5 Aircon is suitable for HDB. The metal bracket outside your house is also subjected to weight constraints of 80kg.
OUR TESTIMONIALS
Aircon Trunking
If this is a condominium and landed property, you will probably only need aircon trunking on the outside. For HDB units where aircon trunking is necessary, the aircon trunking brand does not affect your installation. But it has an impact on future overhaul jobs done on your air conditioning unit.
Proper aircon trunking is essential for concealing refrigerant pipes, electrical wiring, and drainage hoses, ensuring a clean and aesthetically pleasing installation. At Silverback Aircon, we use high-quality, durable materials for trunking to protect components and maintain optimal airflow. Our expert technicians meticulously plan and install trunking to minimize obstructions and ensure efficient system performance. We also prioritize seamless integration with your interior design while adhering to safety and functionality standards.
Electrical Cable
This electrical wiring system includes the aircon wire that connects the condenser to the fan coil unit inside your home, as well as another set of electrical cable connecting the compressor to the main electrical point. The two prominent brands of wire in Singapore is Sigma cable and Keystone. They are both Singaporean brands. So, when you are installing your aircon wiring, do take note of the brand of the wire that your technician is using.
Proper electrical cabling is vital for the safe and efficient operation of your aircon system. At Silverback Aircon, we use high-quality, durable cables that meet industry standards to ensure reliable power supply and minimize the risk of electrical faults. Our experienced technicians carefully plan and install electrical wiring to match your system’s requirements, ensuring compliance with safety regulations. By prioritizing precision and safety in our electrical installations, we deliver aircon systems that operate seamlessly and provide long-term peace of mind.
Aircon Piping
In order to cool a room, copper pipes, running from the condenser unit to the fancoil unit, circulate refrigerant gas. Copper pipes are the most expensive materials involved in aircon installation. It is recommended that you get good-quality copper piping. There is also a certain thickness used as a minimum in selecting copper pipes for aircon refrigerant lines. It is termed as standard wire gauge. For normal aircon materials, it is SWG23. For upgraded materials, it is SWG22. As much as possible, always go for the upgraded ones. The cost of replacing your aircon piping could be close to a thousand dollars for a system 3 HDB aircon system.
High-quality copper piping is essential for the efficient and reliable operation of your aircon system. At Silverback Aircon, we use durable, corrosion-resistant copper pipes to ensure optimal refrigerant flow and long-lasting performance. Our skilled technicians meticulously measure, cut, and install copper piping with precision, minimizing bends and refrigerant line leaks to maintain system efficiency. By using premium materials and expert installation techniques, we ensure your aircon system operates at peak performance while reducing the risk of future maintenance issues.
Insulation
Similar to copper pipe thickness, aircon insulation thickness is also a critical factor in aircon installation where the biggest problem is condensation from the copper pipe. The thicker the insulation, the harder it is for condensation problem to occur. There is no actual way, however, to fully end condensation. In extreme cases, the whole set of pipework is changed to minimize condensation.
Effective insulation is crucial for maintaining energy efficiency and preventing condensation in your aircon system. At Silverback Aircon, we use premium-grade insulation materials to minimize heat loss, reduce energy consumption, and ensure optimal cooling performance. Our team carefully installs insulation around refrigerant pipes to prevent condensation buildup, which can lead to water damage or mold growth. By prioritizing proper insulation, we help extend the lifespan of your aircon system while keeping your energy bills in check.
Water Pipe
Your air conditioner needs a water pipe to drain off the condensate water from the evaporator coil all the way to the floor trap. 13mm is normal for piping dimensions in aircon water pipes. The upgraded size 16mm. The bigger the water pipe, the less likely it is to get choked.
Proper installation of water pipes is crucial for efficient condensate drainage and preventing leaks in your aircon system. At Silverback Aircon, we use high-quality, durable PVC pipes designed to handle condensation effectively and resist wear over time. Our technicians ensure precise installation with the correct gradient to facilitate smooth water flow, minimizing the risk of blockages or overflow. By prioritizing quality materials and expert workmanship, we help maintain a clean, leak-free, and efficient aircon system for your home or business.
Aircon Installation Price
When we talk about ‘aircon installation price,’ we mean installing the unit provided if you already have the aircon materials. The installation price depends on the type of property (HDB, condo, landed property, or commercial space) and length of copper pipe. For simplicity, we have estimated ranges of aircon installation prices below.

Where to Buy Aircon in Singapore
Most of the time, you will think of big box retailers like Courts or Harvey Norman. However, you can actually buy your Aircon from other places as well. Such as from your interior designers and Aircon companies like us. In addition, you can read up more on the link above if you wish to know where you can buy aircon in Singapore.
6 Things YOU HAVE To Look For During an Aircon Installation
Here are the important things you have to look for when installing an aircon:
1. Aircon Materials Used
We can’t emphasize enough the importance of using quality aircon materials. For one, subpar aircon materials may result in faster condensation issue. In the long run, your aircon copper pipe (for your refrigerant line) is more susceptible to damage if you use thinner copper pipes.
2. Design
As an aircon installer, we can only advise you on where to install your unit to achieve maximum effectiveness in its cooling capacity. But with regards to design, you will have to visualize how it will look based on where you want it installed. The installer will not be able to decide your aesthetic preferences for you.
3. Aircon Trunking Location
Once the installer has installed the trunking and copper pipes, they will not be able to reverse the action. Hence, you will have to have proper consideration first before deciding on where to install the trunking first. Furthermore, you have to consider whether the trunking will take up space in your room. For example, if your bedframe is leaning against the wall, placing the trunking at the bottom part of your room will take up that space. So your usable room size will effectively be smaller.
4. Proper BTU Sizing
One of the most important things to establish before beginning the aircon installation is to ensure that the customer agrees to the BTU sizing. For example, a system 4 aircon in a HDB flat usually cannot power up 3 bedrooms and 1 living room at the same time. The customer has to understand that first before installation. An option of having two condensers, for example, will be suggested.
5. Proper Communication with the Aircon Installer
We find this to be the most important point. Most aircon installation issues stem from the lack of proper communication with the installer. The owner may claim that the location of the aircon is not right. Or, the trunking location is not what they visualised. Hence, a smooth two-way communication between the installer and home owner is important.
6. Aircon Bracket Installation
Every aircon company is supposed to have a BCA-licensed representative for the installation of the aircon bracket. In reality, most companies do not have that. But it is much, much safer if you engage with an aircon company that has it. Because if anything happens to the aircon bracket that you installed, you won’t be fully held responsible. Aircon bracket-related incidents, however, are rare. Still, the BCA-licensing procedure remains a protective measure by the Singaporean government. It ensures that all aircon installations follow the proper SOP and will not end up with brackets failing, their heavy compressors crashing down the sides of HDB buildings.
To ensure a smooth and efficient aircon installation process, it’s important to prepare your space beforehand. Clear the area around the installation site, including walls and ceilings, to provide easy access for the technicians. Remove any furniture, decorations, or obstacles that may hinder the installation. Ensure the power supply is readily available and functioning, and inform the installation team of any specific electrical requirements. Lastly, confirm the chosen location for the indoor and outdoor units, considering factors like airflow, accessibility, and proximity to power sources. Proper preparation helps avoid delays and ensures a hassle-free installation experience.
Installing a split-type aircon yourself requires careful planning and precision. Here’s a step-by-step guide:
- Choose the location. Select suitable spots for the indoor and outdoor units, ensuring proper airflow, drainage, and accessibility.
- Mount the indoor unit. Secure the mounting plate to the wall, ensuring it’s level. Drill a hole through the wall for the piping and cables.
- Install the outdoor unit. Place the unit on a stable, level surface or mount it securely on a wall bracket.
- Connect the piping and aircon wiring system. Run the refrigerant pipes, drainage hose, and electrical cables through the wall hole. Connect them to both units, ensuring airtight seals.
- Vacuum the refrigerant lines. Use a vacuum pump to remove air and moisture from the lines, preventing system inefficiency.
- Test the system. Power on the aircon and check for proper cooling, drainage, and airflow.
Note: DIY installation can be complex and risky. For optimal performance and safety, it’s recommended to hire professional technicians.
Installing an aircon in your HDB flat requires careful planning to comply with HDB guidelines and ensure optimal performance. Here’s what you need to know:
🔖HDB Approval. Ensure your aircon installation adheres to HDB aircon installation guidelines, especially for external unit placement and structural modifications. You do not need a hdb Aircon installation permit unless you are installing 2 Aircon compressor in a hdb house without an Aircon ledge. And most of the time, in those cases, you may not need a permit as well.
🔖Location Planning. Choose suitable spots for the indoor and outdoor units, considering factors like airflow, noise, and accessibility. Outdoor units must be installed on designated brackets or HDB aircon ledges.
🔖Electrical Load. Check your flat’s electrical capacity to ensure it can support the aircon’s power requirements.
🔖Professional Installation. Hire BCA-licensed technicians to handle the installation, ensuring safety, compliance, and proper system setup. We can generate a hdb aircon installation report if need be.
🔖Maintenance Access. Plan for easy access to both units for future servicing and repairs. We prepared an HDB aircon piping guide which you might find useful for your planned installation.
By following these guidelines, you can enjoy a hassle-free and compliant aircon installation in your HDB flat.
Except for HDB aircon installations, where regulations are very specific on all aircon installations to be done only by BCA-registered aircon service professionals, there might still be an impulse to do a cost-cutting DIY installation job. There are significant risks associated with DIY aircon installations. Improper installation can lead to refrigerant leaks, electrical faults, or even fire hazards due to incorrect wiring. Poorly installed units may also suffer from inadequate cooling, water leakage, or excessive noise, resulting in higher energy bills and frequent repairs. Additionally, DIY installations often void manufacturer warranties, leaving you unprotected against future malfunctions. Without the expertise of certified professionals, the risk of personal injury or damage to your property increases, making DIY aircon installations a potentially costly and an overall dangerous endeavor.

FAQ on Aircon Installation
| Question 6 |
How to know if I have the right electricity coverage?
If you already have a multi-split ac unit installed at home, chances are you already have the right electricity coverage. However, if this an older HDB unit that doesn’t have a multi-split unit installed yet, you might not have a 15amp power point plug in your master bedroom. In this case, there will be additional cost in installing a power point there. |
| Question 7 |
What if I need to turn on all my Air-conditioners at the same time?
If you are living in a 4 room flat and above, and you are installing an Aircon in all your rooms including living room, you typically won’t be able to just install one outdoor unit because it won’t have enough BTU to support turning on all your indoor units. |
| Question 8 |
What to do if I have built in cabinets in my room?
For an existing HDB unit, you might have built in cabinets at home which some of the Aircon piping might be hidden inside the built in cabinet. Therefore, when you are installing your Aircon you might not be able to change the piping inside. If this is an area of concern for you, you might want to contact us for a site visit to your place. |
| Question 9 |
What can I do if I do not have an Aircon ledge?
Newer HDB units come with Aircon-ledge and the outdoor unit will be placed on such platforms. For older HDB units, you will have to install a metal bracket (usually located outside the master bedroom). So when you are purchasing your AC, you will have to factor this in. |
