Concealed Duct Overview
Like other ductless models, a concealed duct system consists of two parts; an outdoor condensing unit, and an indoor air handler installed in the ceiling or a furr down. The indoor unit and outdoor unit are connected by refrigerant and electrical lines that run through a 3" opening in an exterior wall. This system requires a licensed HVAC technician to connect the lines between the indoor and outdoor components.
The advantages of Friedrich Precision Inverter Technology
Friedrich ceiling cassette ductless split systems feature variable speed compressors and fans (called Inverter Technology), which reach the desired temperature faster, maintain it more accurately and reduce energy consumption with fewer compressor startups and shutdowns. Friedrich Precision Inverter uses 1 Hz increments for near zero wasted energy.
