• Wall-mounted split air conditioners: These air conditioner types are ideal for homes with several rooms, and they are the most common type of air conditioner in Bishan. These air conditioners are connected to an outdoor condensing unit through piping in the wall, which compresses refrigerant gas and sends it into the indoor units. The cooling capacity of these air conditioners can range from small to very large, which suits the different sized rooms in the apartments and landed properties of Bishan.
• Ceiling cassette air conditioners: This type of air conditioner is very common in some landed properties and many shops and offices in commercial buildings. They are also connected to an outdoor condenser like wall-mounted types. Our team has some members who specialise in ceiling air conditioners, which are typically more difficult and complicated to service than wall-mounted types.
• Window air conditioners: Bishan contains a mix of apartments and landed properties, and window air conditioners are used for some smaller rooms that are not connected to the home’s wall-mounted split system. Maintenance of the filters can be done by end-users, however window air conditioners have a complex internal design and can be troublesome to dismantle from the window, so periodic servicing or chemical cleaning is best performed by professionals.
• Portable air conditioners: There are some buildings that prohibit the installation of window air conditioners for smaller rooms, and residents often buy portable air conditioners in these cases. Portable aircons come in a variety of cooling capacities, ranging from 5000 up to over 15,000 BTU, which is enough to cool a small space. They convenient and can be moved around the room, but they are difficult to service and require an experienced aircon servicer to clean them.
