HVAC/R Airmen keep buildings, hangars, and mission equipment at the right temperature: boilers, chillers, refrigeration, and building controls. Civilian employers call that HVAC technician, stationary engineer, and building controls work.

A note from the founder

I served on active duty in the U.S. Air Force from 2001 to 2009 as a 2W0 Munitions Systems specialist and a C-130 Loadmaster. I didn't work Heating, Ventilation, Air Conditioning, and Refrigeration, so this page leans on O*NET and BLS data rather than my own memories. The problem is the same, though: your experience is valuable, and it has to be written in the civilian employer's language.

Questions veterans ask

Do I list my AFSC on a civilian resume?

Lead with a civilian title, such as Heating, Air Conditioning, and Refrigeration Mechanics and Installer, and add a secondary line like 'Military title: Heating, Ventilation, Air Conditioning, and Refrigeration (3E1X1)'. Recruiters search civilian titles; the AFSC helps veteran-friendly employers and federal HR.

What civilian jobs fit 3E1X1 best?

O*NET maps 3E1X1 to 15 related civilian occupations. The closest matches include heating, air conditioning, and refrigeration mechanics and installers, stationary engineers and boiler operators, and control and valve installers and repairers, except mechanical door.

How many Airmen work in 3E1?

The Air & Space Forces Magazine 2025 Almanac lists 1,350 Total Force enlisted Airmen in 3E1 (Heating) as of Sept. 30, 2024, which makes it one of the largest enlisted specialties. That's a lot of veterans competing for the same civilian roles, so a clear translation matters.
