Nortek Global HVAC Launches 20-SEER Air Conditioner

New iQ Drive® model uses inverter technology.


St. Louis, March 5, 2015 — Nortek Global HVAC introduces a new inverter-driven split-system air conditioner thatachieves 20-SEER cooling in all sizes and matches. iQ Drive® model FS4BG is powered by an inverter-driven rotary compressor for ultra-high energy efficiency and ultra-quiet operation. It’s available in 2, 3, 4 and 5 ton capacities.

The new iQ Drive air conditioner modulates from approximately 49% to 118% of capacity in five steps, making constant, small adjustments to meet the cooling demands on the home. It operates as quietly as 59 dBA.

“Inverter-driven products operate very quietly and create exceptional indoor comfort,” says Tim Alford, product manager at Nortek Global HVAC. “That’s why we’ve developed a robust line of inverter systems. It’s a way for contractors to differentiate themselves in the home and provide consumers with a high level of system performance.”

Installation is simplified with the new iQ Drive FS4BG model. This air conditioner operates with most two-stage thermostats and does not require shielded thermostat cable.

Additionally, the FS4BG air conditioner features an all-aluminum Micro-Channel condenser coil to reduce instances of corrosion, optimize heat transfer and increase durability and reliability.

The new 20-SEER FS4BG air conditioner joins other inverter-driven iQ Drive products by Nortek Global HVAC, including the companion 19-SEER/10-HSPF FT4BG heat pump and the industry-leading 20-SEER/81%-AFUE R6GI gas/electric packaged unit.
