LG “Reliable to Extreme Degrees” (RED) heating technology has been added to more products including the Multi F and Multi F MAX multi-zone outdoor units. LGRED technology not only delivers heat when traditional models are unable, but also does so with remarkable energy efficiency offering comfort to users living in cold climates. LGRED provides 100-percent-rated heating capacity down to five degrees Fahrenheit with continuous operation down to -13 degrees, offering comfort to users living in even the coldest climates. Created for residential and light commercial installations, these robust multi-zone systems have the option to be installed fully ductless for optimal performance or combined with ducted systems, including the new LG 4-Way Vertical Air Handler Units (VAHUs), for increased design flexibility. The LGRED Multi F systems also feature a SEER rating of up to 21, qualifying them for ENERGY STAR certification, as well as eligibility for participating local utility company rebates. lgredheat.com
