Hi everyone! Basically my family (more like me and my mum) is considering on installing aircons in our close to 20 year-old flat. My parents basically bought the flat probably in 1996 and it's a 4-room type 5A HDB flat.
The measurements (in mm I guess?) on the floor plans are:
Living Room = 6750 x 4700
Main Bedroom = 3000 x 5600
Bedroom 2 = 3400 x 3500
You need Inverter Sys2 or Sys3 aircon depend on your room size.
Air-Conditioner BTU Calculation (Estimate)
Step 1:
Calculate the volume of the room
For example - 3.5m x 4m = 14 / 2 = 7
Step 2:
With the given answer (7). Match with the closest BTU capacity air-conditioner below with your answer which is between 9,000Btu.
Based on this quote, the BTU capacity of respective rooms:
Living room = 6.75 x 4.7 = 31.725 / 2 = 15.8625
Main Bedroom = 3 x 5.6 = 16.8 / 2 = 8.4
Bedroom 2 = 3.4 x 3.5 = 11.9 / 2 = 5.95
Our biggest concern is the huge increment in electricity bills after installation hence I guess our priority is set on energy efficiency. The aircon in the living room would only be occasionally used (i.e. less than 2 times a month) and the kitchen has a sliding door which can be closed to cool the living room down faster. As for the rooms, it'll be turned on more frequent in bedroom 2 than main bedroom.
We're looking at a budget $3200 with everything included (compressor brackets, powerpoints, insulation and whats not) - it's the first time we're installing so we've got nothing at all.
Very very much appreciated if anyone could give any solid recommendations or valuable insights on their aircon installation experience!
