Using an advanced variable-speed system, a NuTone air handler provides ultra high efficiency improving ratings to 16 SEER and 8.5 HSPF when matched to select NuTone air conditioners and heat pumps. Patented variable-speed technology, is the most-advanced and efficient blower motor design today. Unlike the abrupt start/stop cycles of conventional induction motors, variable-speed units ramp up to speed gradually to eliminate uncomfortable temperature swings in your home.
On mild days, which typically average about 80% of the cooling season, a system that idles down to reduced-cooling capacity is actually much more efficient, and quiet.
NuTone's two-stage systems are built with this purpose in mind. In the first stage, the air handler uses approximately 75% of its total capacity running more slowly, quietly and efficiently. Then, during the hottest extremes--a second stage boosts capacity ramping up gently to maximum speed. Ramping gradually through cooling cycles eliminates temperature swings while greatly reducing noise.
Since air is circulated at longer cycles more continuously, room temperatures are balanced and more comfortably mixed.
Best of all, by reducing energy consumption in the low-speed, a variable-speed air handler can reduce your energy bills by hundreds of dollars each season.
This air handler is the indoor section of a complete system.
