Builder's Frequently Asked Questions

The South Coast Air Quality Management District (South Coast AQMD) is the air pollution control agency for all of Orange County and major portions of Los Angeles, Riverside, and San Bernardino counties, including the Coachella Valley. This area of 10,743 square miles is home to more than 17 million people–about half the population of the whole state of California.
Under Rule 1111, an Ultra-Low NOx Furnace is a residential furnace between 65,000 and 175,000 BTUs (British Thermal Units) that meets the South Coast AQMD’s nitrogen oxide (NOx) emissions limit of 14 ng/J (nanograms per joule). This is required for use in single-family, multi-family, and small commercial properties within the South Coast Air Basin. The previous NOx emissions limits on these types of furnaces were 40 ng/J.
