About the company

API Hvac Services, Inc., an Oak Creek, Wisconsin–based mechanical systems and HVAC contractor, operates exclusively as a prime contractor on firm-fixed-price federal purchase orders and definitive contracts for emergency water-line, steam-pipe, and HVAC repairs at VA medical facilities and Coast Guard installations in the upper Midwest. The company competes in full open-market procurements with no set-aside designation.

API Hvac Services does not subcontract work and operates as a direct service provider to two concentrated federal customers. Veterans Integrated Service Network 12 (Department of Veterans Affairs) represents 42 of the vendor's 100 recorded federal awards (42% of the total count) and $1.4 million of the combined potential value across all awards. The Department of Homeland Security's Coast Guard accounts for 9 awards and $229 thousand in combined potential value, covering sewage-system and water-main repairs at Sector Lake Michigan and related facilities. Together, these two customers cover 72% of the vendor's award count and 82% of combined potential value. The Air Force Air National Guard, Department of the Navy, and Navy Installations Command round out a smaller customer base with five, fourteen, and two awards respectively. Activity is sporadic — six awards in 2022, two in 2023, five in 2024, one in 2025, and five in 2026 — with a most recent award on August 12, 2026, for a $38.2 thousand emergency water-main repair at the Milwaukee VA with an ultimate completion date of August 26, 2026.

Capability focus is narrow and operational: emergency and emergency-related repairs to water mains, condensate pipes, steam pipes, fire-protection systems, and sewage-lift infrastructure at federal healthcare and operational facilities. Representative work includes a $285.8 thousand emergency steam-condensate pipe leak repair and modification contract at VA Building 70 (awarded June 12, 2026, completion September 30, 2026); a $81.6 thousand water-main repair order at the Milwaukee VA (awarded April 28, 2026, completion September 30, 2026); a $62 thousand emergency north-campus water-main repair at Clement J. Zablocki VA Medical Center (awarded July 2, 2026, completion August 2, 2026); and a $26.4 thousand Coast Guard Sector Lake Michigan emergency water-main repair order (awarded December 30, 2024, completion January 2, 2025). All awards are firm fixed-price with no small-business set-aside. The vendor sits on one Navy indefinite delivery contract (N6246700D7751, with 15 task orders) and a Blanket Purchase Agreement (695C30570), suggesting access to standing-order vehicles, though task-order activity in the source data reflects direct awards rather than formal IDIQ utilization.

Service Contract Inventory reports show minimal SCI-reportable activity — $154 thousand in invoiced revenue across three prime contracts in FY2023, with 0.7 FTEs delivered that year and no reported SCI invoicing in FY2022 or FY2024. Median government-paid rates on SCI-reportable contracts centered on $99.37 per hour. The SCI dataset excludes most of API Hvac's federal revenue, as emergency repair purchase orders under $150 thousand reporting threshold dominate the award portfolio; the SCI figures represent a narrow subset of the vendor's total federal services activity. Combined potential value across all 100 recorded federal awards is $2.1 million, with $2.2 million in combined obligated dollars, reflecting the small-dollar, high-frequency emergency-repair posture characteristic of facility maintenance contracts at regional VA and Coast Guard installations.
