Most public housing in Singapore is owner-occupied. Under Singapore’s housing ownership program, housing units are sold to applicants who meet certain income, citizenship, and property ownership requirements, on a 99-year leasehold. The estate’s land and common areas continue to be owned by the government. 

These are the General Guidelines Upon Installing An Aircon Unit in an HDB Unit:

1) You are responsible for the proper installation, safety, and stability of your aircon unit (casement/ window unit/ split type).

2) Submit the SP Services Ltd (SPSL) Form CS/5H endorsed by HDB to SPSL for testing of any new wiring

3) You need to email an installation in PDF with 98KB, to the HDB Branch managing your flat within 14 days after installation.

4) The aircon unit ledge is to be used strictly for placing the air condensing unit only.

Guidelines governing the installation for HDB Units:

Here are the aircon installation guidelines for HDB blocks under MUP or HIP:

2) A maximum of two split-type aircon condensing units can be installed.

3) The maximum weight allowed is 110kg per wall panel regardless of whether the installation is on the external wall or aircon unit ledge.

4) For wall-mounted aircon condensing units, each wall panel is allowed to have only one aircon condensing unit.

Things to remember upon installing an aircon unit for HDB:

1) Types of equipment

If you are planning to install new aircon unit equipment for HDB, there are several options for you to choose from. There are floor-standing aircon units that are portable and use little room space. This would be ideal if the HDB is a bit squeezed with limited window space. Then there is the split aircon unit option which is rather expensive. It has the advantage of being compact and attractive to add to its high-efficiency qualities.

2) Ideal temperature

You need to determine the ideal temperature that the HDB office agrees upon. Once this is done, figure out the difference between the HDBs’ current temperature and the temperature you are seeking. After this, professionals use a special method called a Manual J that helps determine the needed unit size. Research this method more to figure out if it is a DIY job. If it is not, call a professional aircon servicing company. After this method is implemented, the ideal cooling load can be calculated using the first two temperatures mentioned.

3) Room size

It is important to consider the type you want and the capacity of the room to be managed. Even if you install the best brand or type of aircon unit, it would not serve the purpose of the room being either too small or too large. Make sure there’s enough space or room at HDB to fit the outside unit and also the indoor equipment. Sizing the property at HDB to a suitable aircon system is fundamental. You don’t want something too big or not big enough for HDB building mainly because, either way, the bills will increase while effectiveness will decrease.

4) Ductwork

Ensure that the ductwork inside the HDB can hold a main aircon unit system and write down changes that may need to be made. Including closing the ductwork if you need to.

5) Maintenance of the aircon

Knowing how to maintain the aircon unit equipment is very important because it helps you save maintenance costs. If a regular check-up of the equipment is not done, you might have to overhaul the equipment and replace it with a new one too fast. There are good engineers and aircon servicing professionals in Singapore who can give you the necessary advice to help keep the unit running all year round.
