Performance

For over a century, people have trusted Lennox to make their lives more comfortable. In keeping with that tradition, the Elite 90™ gas furnace brings a new level of economical heating to your home. It now features the new SureLight™ ignition system, which is many times more rugged and reliable than any other ignition system available today. And, with its patented DuralokPlus™ aluminized and stainless steel heat exchanger, the Elite 90 gas furnace is able to provide high-efficiency operation while resisting corrosion. That's the kind of quality you've come to expect from Lennox.

Warranties

Lennox builds according to internationally recognized ISO 9002 manufacturing standards. And, we stand behind our products with some of the best warranties* in the industry. The Elite 90 gas furnace is backed by a lifetime limited warranty on the heat exchanger. All remaining components carry a 5-year limited warranty. That's one more reason to trust Lennox.

Energy Savings

With efficiencies ranging from 90.0% to 92.4% AFUE, the Elite 90 gas furnace can reduce your energy bills by one-third compared to older furnaces. Older furnaces operate at a much lower efficiency, which means a lot of the available heat is wasted. The Elite 90 is designed to produce more heat per fuel dollar, meaning you'll stay warm for less. Savings like that make replacing your old unit truly affordable.

This chart compares the average 3-year savings you an expect from the Elite 90 furnace versus furnaces with lower efficiency ratings. Costs are based on industry averages for a typical 3-bedroom house in a city with 2,000 heating hours with a 60,000 Btuh load, and $.61ccf for gas. Your actual savings will vary depending on the weather, local fuel rates and your lifestyle.
