Need help from the aircon gurus here.
Thinking of installing aircon in my parents' 40+ years old flat. The power system has never been upgraded before. From the HDB site, it seems that the flat has a 30A main breaker and the current limit allowed is 8.5A.
1. If I only need to cool 3 bedrooms, does that mean I should get a System3?
2. Each room is roughly 100ft^2, how much BTU should I allocate?
3. Does each FCU require its own power socket? We only have one power socket per room (which is used for other purposes), so are there systems that can draw power from the outdoor unit instead?
4. If the FCU draws power from the outdoor unit, can the 8.5A limit still be met?
5. Do I buy from places like Harvey Norman, Best Denki and Courts or would it be better to approach specialised vendors like Coolserve?
6. If the power system is insufficient to install an aircon, what can I do? Anyone with experience?
Thanks!
