Two Stage Gas Furnace
Gas Furnaces in Oneida, NY and surrounding areas

For Maximum Comfort with Maximum Efficiency!

The two-stage design reduces temperature swings and on-off furnace cycling by providing a gentle, steady flow of warm air.  It does this by operating in the low stage most of the time, automatically shifting to the high stage when there's a demand for extra heat.

The low stage saves on utility bills because the burner flame is smaller and the blower fan runs at a slower speed, but even in the high stage, the furnace is a fuel miser at 95% AFUE.

An additional benefit is improved indoor air quality as air passes through the filter whenever the furnace is running, on high or low fire.  Available in upflow only.

The GTUA 95% Series is Energy Star rated and models may qualify for tax credits for energy efficiency.  See your tax professional for how this may apply to you.
