DALLAS - ICP is showing off its high-end Ultimate Systems. The systems feature two-stage cooling with a mechanical unloading scroll. The quiet, two-speed condensing fan is coupled with a sound jacket over the compressor for a low-noise unit.

A variable speed furnace and air handler, along with high-end IAQ components complete the system. Shown in the photo are the furnace and air handler with humidifier and electronic air cleaner.
