• Wall-mounted Ductless Split-type Air Conditioners: Offices, shops, and rented apartments located around Novena’s business district make use of wall-mounted, often ductless, split-type air conditioners that can effectively cool down large areas without the need of additional units. Popular among offices, split-type air conditioners are sleek, modern, and controllable via remote. This type of unit, however, will require frequent professional maintenance as it is used in high traffic areas.
• Window-type Air Conditioners: Window-type air conditioners are one of the most common types of air conditioners throughout Singapore, and for a good reason. This type of unit is accessible, being offered by most known brands, and are relatively inexpensive. Window-type air conditioners are easy to maintain at home, but do require some professional cleaning and maintenance every now and then.
• Centralized Air Conditioners: The malls and shopping districts near Novena Square and Square 2 use centralized air conditioning to cool down the entire area, with only a single point of control for the entire cooling system. This type of cooling system is much more difficult to maintain, as it requires professional services to clean, assess, and repair any problems that may arise from usage.
