Lennox® natural gas furnaces—In addition to using less energy to operate, energy-efficient heating systems can be quieter, reduce indoor humidity and improve the overall comfort of your home.

Upgraded wall insulation—The batt or blown insulation in your home meets or exceeds local R-value requirements and delivers greater home comfort, reduced heat gain in the summer and heat loss in the winter, and lower utility bills.

Fresh air ventilation—A special duct to the outside draws fresh air in to your home, filters it, mixes it with indoor air and distributes it throughout your home to keep air inside your home as healthy as possible.
