Hi Bro, can share the store info? I think that's quite good price for 1.5hp York.

I'm thinking to use non-inverter 1.5hp(or even 1hp) for blowing cool air only. My living room is connected to dining place and also the kitchen. I think there is no point to install inverter and higher hp Aircon Coz the whole area will never get cool below 25c. So even higher power Aircon will work at 100% capacity. I just want to use the Aircon during friends and family visit so they don't feel like in 35c.

Do you guys think it's a good idea?

Previously, most of the concealed piping is for non-inverter. But you can use Daikin inverter because it use older gas that's compatible with non-inverter piping.

But now maybe some newer house already got inverter concealed piping. You should check first.
