I installed two units Panasonic inverter 1.5hp and 1.0hp.
1.5hp total17ft and first 5ft is free so the balance have to pay 12ft @ RM 26/ft = RM 312
1.0hp total 25ft and first 5ft is free so the balance have to pay 20ft @ RM 18/ft = RM 360
Casing to cover the black rubber, total RM 330.
Is it a normal expenses?

I bought in Sarawak so the shipping cost is much higher than w.malaysia there. Bought in SenQ, 1.5hp RM 1648 + 110 installation cost, 1.0hp 1388 + 50 installation cost. The installer told me, 25ft is still within a normal range so wont reduce the efficiency however more than 30ft the performance have impact.
