WARM LOCALLY, COOL GLOBALLYLennox® ultra-low emissions gas furnaces are the first of their kind available, built to exceed
California’s stringent air quality regulations that were designed to reduce global warming. The
key emissions, a group of reactive gasses known as Nitrogen Oxides (NOx), not only contribute
to rising global temperatures, but also to ground-level ozone that can inflame the lungs, worsen
asthma, and cause a host of other respiratory problems. By greatly reducing these emissions, these
furnaces ensure perfect warmth as well as cleaner and healthier air for you and your family.
