York's TM9V 96 percent efficient natural gas furnace series ranges in price from approximately $1,600 to $2,000 as of 2015. The TM9V series is Energy Star-certified and is available in seven different capacity options, ranging from 40,000 BTU to 120,000 BTU.
The York TM9V series is a compact furnace unit that is set up for up-flow or horizontal application, but includes a down-flow conversion option. A two-stage gas valve and variable speed blower increase the furnace's efficiency and effectiveness. York furnaces carry a 10-year limited warranty on parts and a lifetime warranty on the heat exchanger. York recommends the use of its TM9V models with its Affinity Residential Community Control thermostat to maximize energy efficiency.
