3334

Analysis

NAICS 3334 is the 2022 industry group for ventilation, heating, air-conditioning, and commercial refrigeration equipment manufacturing, part of 333 (Machinery Manufacturing).

It has only one more detailed code, 33341, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 1,685 US establishments in this code in 2023, employing 147,794 people at an average annual payroll of $66,480 per employee (46th percentile of national industries). 23% of the establishments have fewer than five employees, which points to larger operations.

By establishments it ranks 6th of the 7 codes at this level within Machinery Manufacturing, with 7.8% of them.

Between 2018 and 2023 the number of establishments fell 0% and employment rose 15%. 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.
