Analysis
NAICS 333414 is the 2022 national industry for heating equipment (except warm air furnaces) manufacturing, part of 33341 (Ventilation, Heating, Air-Conditioning, and Commercial Refrigeration Equipment Manufacturing). Census lists 27 example activities under it in the official index.
By establishments it ranks 3rd of the 3 codes at this level within Ventilation, Heating, Air-Conditioning, and Commercial Refrigeration Equipment Manufacturing, with 21% of them.
County Business Patterns counts 354 US establishments in this code in 2023, employing 17,079 people at an average annual payroll of $70,937 per employee (54th percentile of national industries). 29% of the establishments have fewer than five employees, which is close to the national mix.
Census lists 6 related activities that belong elsewhere, most often in 333415, 335210, 335220 and 332410. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
Its index entries, the activities Census uses to assign businesses to this code, include baseboard heating equipment manufacturing, boilers, heating, manufacturing, burners, heating, manufacturing and fireplace inserts (i.e., heat directing) manufacturing, among 27 in all.
Between 2018 and 2023 the number of establishments fell 8% and employment rose 13%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
Official definition
