Cool and heat up to four zones
Like other ductless models, a wall-mounted system consists of an outdoor condensing unit and 1-4 indoor air handlers 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.
Single-zone cooling: This system has one outdoor condenser and one indoor air handler that cools one room. The new 115V models have cooling capacities of 9000 and 12000 Btu, and the 230/208V models range from 18000 to 33000 Btu.
Single-zone heat pumps: This system has one outdoor condenser and one indoor air handler that cools and heats one room. Cooling capacities range from 8500 to 22000 Btu, and heating capacities range from 10000 to 27600 Btu.
Multizone heat pumps: This system has one outdoor condenser and up to four indoor air handlers that cool and heat individual rooms. Each indoor unit is separately controlled for customized comfort settings, and units can be turned off in unoccupied rooms to save energy. Multizone systems are available in numerous configurations, with total system capacities between 18000 and 36000 Btu.
The advantages of Inverter Technology: Friedrich wall-mounted 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.
Wall-mounted ductless split systems can cool and cool/heat 1-4 zones. Multizone systems let occupants independently set the temperature for individual comfort. Units in unoccupied rooms can be turned off to save energy.
Hard-to-find 115V 9000 and 12000 Btu/h models are available. Capacities up to 3 tons.
