Q1. How to choose an air conditioning system for the house?
  1. Decide on the areas that require air conditioning.
  2. Determine the cooling capacity required.
  3. Determine the types of air con that you want.
  4. Consider your budget
Q2. How do I determine the air conditioner capacity required for my room?
For a quick estimation, we can use the rule of thumb:
Area (Length x Width) X 65 = BTU/hr E.g.
Room size 10ft X 10ft - 10 X 10 = 100ft2 X 65 = 6,500BTU/hr
Q3.What is the difference between a window unit and a split system?
A window unit is a self-contained packaged air conditioner. All components are housed within the unit. It is installed through an opening in the wall and no inter-piping connection is required.

A single split, as it is called, comprises 2 parts that make up a system air conditioner: the outdoor unit (condenser) and indoor unit (Fan coil). The FCU is a cooling coil that cools the room, interconnection piping between the condenser and fan coil is required to run this system.

A multi-split unit consists of 1 condensing unit connected to more than 1 fan coil unit thus having the capability to cool multi rooms. The condenser can be a single compressor or multi compressors. Because of the design, single split and multi-split units are quieter than window units.
Q4. What is an inverter air conditioner?
An inverter air conditioner uses an inverter circuit to regulate the rotational speed of the compressor to match the output of the compressor to the cooling pump load. This reduces the number of times the compressor stops and starts as the load varies, so saving on electricity bills and reducing noise levels compared to non-inverter models.
Q5. What is the average life span of a residential air conditioner?
The average life span of an air conditioner is about 6-7 years, but it can be prolonged through proper maintenance by qualified technicians on a regular basis.
