FY2025 federal contract obligations, USAspending.gov

NAICS 333415 obligated $358 million in FY2025 across 3,250 contract actions. DoD is $314 million, VA $18 million, GSA $9 million, State $6 million, DOJ $4 million. The DoD share is installation facility recapitalization plus deployable environmental control units, which are two different products bought by two different communities under one code.

What belongs here

Air conditioning other than motor vehicle, warm air furnace equipment, and commercial and industrial refrigeration and freezer equipment.

  • Steam-side power boilers and heat exchangers belong in 332410.
  • Installing the equipment as a building trade scope is 238210 or a mechanical trade code.
  • Servicing installed systems is 811310.

Competing in this code

124 IDVs against 3,250 actions is low vehicle coverage, so this code competes openly at an average around $110,000. Two federal requirements shape competitiveness. First, refrigerant transition rules mean equipment offered has to use compliant refrigerants over the expected service life, and solicitations increasingly say so. Second, federal energy efficiency requirements for covered equipment set a floor that commercial base models often miss. Deployable environmental control units are a separate niche with military specification requirements on power input, transportability, and sand and dust performance, and that niche has a short qualified list.

Frequently Asked

NAICS 333415 questions, answered.

What is the SBA size standard for NAICS 333415?

SBA sets it at 1,250 employees, counted as a 24-month average headcount across your company and every affiliate, not revenue. At or under that number you are small on NAICS 333415 solicitations and eligible for the set-asides in this code.

Which agencies buy HVAC and refrigeration equipment under NAICS 333415?

FY2025 obligations: DoD ($314 million), VA ($18 million), GSA ($9 million), State ($6 million), DOJ ($4 million). DoD's spend splits between installation facility recapitalization and deployable environmental control units, which are separate markets with separate requirements.

What compliance requirements apply to federal HVAC equipment purchases?

Refrigerant transition rules, which require offered equipment to use compliant refrigerants across its expected service life, and federal energy efficiency requirements for covered equipment, which set a performance floor above many commercial base models. Both appear in solicitations and both disqualify otherwise competitive offers.

Are deployable environmental control units in this code?

Yes, and they are a distinct market inside it. Military ECUs carry specification requirements for power input, transportability, and sand and dust performance that commercial units do not meet. The qualified supplier list is short, which makes it an attractive niche for a manufacturer willing to fund qualification testing.
