Hi, i'm planning to install air-conditioning units for two rooms in my house. Please quote me for either two 1HP aircon units or one multi-split air con unit for two rooms.Prefered brand is Panasonic.

Can i also ask,my house is quite old with single phase wiring.Will there be any problems?Coz i heard that theres a limit to how many air cons i can install due to the single phase wiring.Thanks!
