For homeowners to buy or replace their home air-conditioning, there will things that you need to consider before making the hefty purchase.
In this article, we will help you list the things that you need to consider, weigh the importance and decide which air-conditioning suits your needs best.
Types Air-Conditioning in Singapore
There are mainly 2 types of air-conditioning that are most common in Singapore to consider when deciding on a purchase. By understanding the various options, you can choose the one that best suits your needs.
Casement Air-Conditioning
A window/casement air conditioner unit is designed to cool a single room which can be a good and easy to install option. It is usually installed when it is not possible or practical to have central air conditioning.
It requires an opening to an outdoor space to ventilate the hot air which will not be suitable if your room has no windows or openings.
It is one of the cheapest air-conditioning that you find on the market.
Wall Mount Air-Conditioning
Wall-mounted air conditioning units, as its name suggests, are placed high on the wall. Placing the air-conditioning above floor level helps cool the area faster as hot air rises & cold air sinks.
Wall mount aircon is ideal for areas such as bedrooms, living rooms, offices, server rooms and shops as it operates via a central compressor which means you can operate your air-conditioning in multiple rooms with only 1 compressor.
The compressors are usually found on the aircon ledge or in older homes, suspended outdoors with a bracket. Wall mount air-conditioning is the most popular aircon for most homeowners.
Understanding BTU (British Thermal Unit)
BTU is a term used in the aircon industry to highlight in terms of how powerful your aircon system is. The higher the BTU, the more powerful and easier it is for your aircon system to cool your desired area.
Below is a table for the estimated btu required to cool the desired space. The requirement may vary depending on the objects & obstructions in the space that deters the flow of air.
| Area Suare Feet (SQF) | BTU Required |
| 250-300 | 9,000 |
| 350-450 | 12,000 |
| 500-600 | 18,000 |
| 650-800 | 24,000 |
It is best recommended that you go for a higher BTU unit to help cool your desired area faster and reduce your electricity bills.
If you choose a smaller BTU aircon unit for a large space, your air-conditioning will need to work harder to cool your desired area which will result in higher electricity bills and might not even be able to cool your desired area.
