Lennox launches new residential gas furnace

Lennox on Thursday released a new residential gas furnace.

What’s happening: The model “offers an efficiency rating of up to 99%” and is “dual-fuel compatible, allowing it to pair with an electric heat pump and alternate between fuel sources to help optimize comfort and efficiency in varying weather conditions,” the company said in an announcement. 

• It’s integrated with a refrigerant detection system, eliminating the need for a separate installation kit. 
• Go deeper

One fun thing: Dave Lennox, who invented a new type of steel furnace in 1895, sold his furnace business in 1904 — which retained his name and evolved into the company known today — for $58,000.
