Split system air conditioners are a cost-effective alternative to central air conditioners, and are perhaps the most common types of ACs found in homes and offices in Singapore. Unlike a central AC, a split AC unit does not require duct lines and is relatively easy to install. However, it is always a good idea to hire a professional technician for installing a split AC unit. Proper installation helps to extend the life span of the unit, and avoid unnecessary servicing and aircon repair expenses in the long run.
A typical a split system air conditioner comes with an indoor component containing the evaporator coil, cooling fan, and expansion valve, and an outdoor component consisting of the condenser and the compressor. Deciding where to install the indoor and outdoor components could be confusing. As a homeowner, you can do your home work to make an informed decision.
• Consider the distance from floor – Ideally, you should install the indoor unit between 7 feet and 8 feet above the floor. If you install it higher, most of the cool air will be used to cool the hot ceiling, affecting the cooling process in other parts of the room. Keeping the unit close to the floor also helps to clean the filters and evaporator coils regularly.
• Avoid obstacles – Make sure you install your indoor AC unit in an unobstructed location. Avoid areas of the wall obstructed by furniture or wall units. Any obstruction to the air flow or circulation may affect your AC’s cooling efficiency and make it prone to sudden failure or breakdown.
• Keep safe distance from electrical or electronic devices – It is also important to install your split Aircon unit at least 3 feet away from other electrical devices, such as, radio, intercoms, antenna, and home security systems. Electrical feedback from those devices may affect the operational efficiency of your split AC system.
• Look for an open space – The outdoor unit releases the hot air, and thus it needs to be installed in an open space outside your home or office. It could be your terrace or the awning above the wall. But you need to make sure there is shade over the outdoor unit to protect it from direct sunlight and rain.
• Find a steady wall – Some outdoor units are heavy and may vibrate while running. This is exactly why you need to mount the unit on a solid, steady surface. Make sure that you use the necessary metal brackets, angles, nut and bolt to hold the unit securely.
• Select an unobstructed location – In order to make sure the hot air does not get any obstruction; you need to install the outdoor unit in a location that has enough free space in the front and sides.
It is advisable that you should consult an experienced aircon servicing and installation expert before deciding where to install your split air conditioner for the best results.
