Hi Air con gurus! I need some urgent help on the following.
I just bought an apt and I intend to replace my existing air con systems as they are 8 years old. The current set up consists of a System 3 (Master room 12k BTU, Guest room 9k BTU, Study room 9k BTU) and a System 2(Living and Dinning room 12k BTU each).
My air con usage is typically daily (Master, Study rooms) and occasionally (Living/Dining/Guest rooms).
I arranged for 2 site inspections but both technicians proposed different configurations:
(A) Follow existing configuration, ie. 3 rooms (System 3) and Living/Dining (System 2). This technician reasoned that this configuration saves on servicing as (given my usage style) I need only to service more frequently on the outdoor unit of System 3 than outdoor unit of System 2.
(B) System 3 (Living 12k, Guest 9k, Study 9k), System 2 (Dining 12k, Master 12k). This technician reasoned that this configuration enables both outdoor units are more evenly utilised, which is better in the long run.
I'm indifferent to both but what do you think? Do both explanations above make sense? Or is there an optimum configuration not stated above?
Thanks so much!
