HOME / CALIFORNIA NEW FURNACE EMISSIONS STANDARDS
Beginning on October 1, 2019, condensing and non-condensing furnaces sold or supplied within the boundaries of The South Coast Air Quality Management District must comply with a NOx Emission limit of 14ng/J. Due to EPA regulations, manufacturers, installers and distributors will no longer be allowed to offer, install or sell non-compliant condensing or non-condensing furnaces. Read on to learn more about how this new regulation will affect homeowners in Sacramento, California, and the surrounding areas.

What are nitrogen oxides?
Nitrogen oxides are a group of gases and compounds composed of nitrogen and oxygen that are emitted from vehicle exhaust, and the burning of coal, oil, diesel fuel, and natural gas – including natural gas furnaces. Nitrogen oxides react with sunlight and other chemicals to form smog, a major issue in southern California. They also cause ground-level ozone, acid rain, water quality deterioration and global warming, as well as respiratory issues like asthma.

Who do these new rules apply to?
Rules 1111 and 4905 apply to manufacturers who sell or distribute natural gas-fired, fan-type central furnaces.
So what do these rules mean for me?
It means that all furnaces installed as of October 2019 must meet 65% lower NOx emissions (from 40 to 14 nanograms/joule or less). Up until October, if you have a furnace installed that does not meet this new requirement, you must pay a fee, which ranges from $225 to $400.
Does Guardian Heating and Air install these new furnaces?
Yes. We are proud to carry high-efficiency, ultra-low NOx gas furnaces from American Standard, like the one pictured below.
