NuTone's Two-Stage cooling air conditioners and heat pumps are up-to-speed with the expectations of today's comfort-minded and energy-conscious consumer. Using the latest two-stage scroll compressor technology, it stands to reason that these air conditioners and heat pumps will cost more up front. But over the lifetime of your initial investment, they'll provide unparalleled comfort, quiet operation, and significant improvements in indoor air quality.
Likewise, they'll pay back dividends providing energy savings worth hundreds of dollars per year along with reduced maintenance costs.
Your NuTone air conditioner or heat pump has been carefully designed and engineered to give you outstanding energy efficiency and years of trouble-free operation. No detail has been left out. NuTone uses only proven components like the Ultra-tech Copeland® scroll compressor. It’s the leaders choice for efficiency, durability, and longevity. Just another “value added” manufacturing step built into all NuTone products.
On mild days, which statistically average about 80% of the cooling season, a system that idles down to a reduced-cooling capacity improves comfort.
Nutone's two-stage systems are built with this purpose in mind. In the first stage, the air conditioner, or heat pump, uses approximately just 68% 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 increase quiet performance.
Since air is circulated at longer cycles more continuously, room temperatures are balanced and more comfortably mixed. Temperature swings are reduced to barely a couple of degrees and hot and cold spots are minimized. Best of all, by reducing energy consumption in the low-speed, a two-stage air conditioner, or heat pump, can also reduce your energy bills by hundreds of dollars each season. With this system, a variable gas or oil furnace and matched indoor coil section is required if you have gas or oil heat. If you have a heat pump, then the matched variable speed air handler indoor section is required to complete the system.
