About API Hvac Services, Inc.

API Hvac Services, Inc., an Oak Creek, Wisconsin-based mechanical systems and HVAC contractor, provides emergency repair and infrastructure maintenance services to federal facilities as a prime contractor operating exclusively in full-and-open competition with no set-aside designations. The company competes on technical merit and local market presence rather than SBA certifications, competing directly against commercial contractors without small business carve-outs.

API Hvac Services serves a narrow but stable customer base concentrated in the upper Midwest. The Department of Veterans Affairs Veterans Integrated Service Network 12 accounts for 41% of all recent awards (40 awards, $1.1 million combined potential value), reflecting API's embedded position as the go-to emergency repair contractor for VA medical center infrastructure at the Milwaukee facility and across VISN 12's multi-state region. The Department of Homeland Security's US Coast Guard places the second-largest volume (9 awards, $229 thousand potential value), also concentrated at the Milwaukee Sector Lake Michigan facility. Together, these two customers account for 71% of award count and 79% of combined potential value. The Department of the Navy, Air Force Air National Guard, and Army National Guard account for remaining volume but with minimal dollar concentration.

API's capability portfolio is narrow and specialized: firm fixed-price emergency repairs to building mechanical infrastructure — water mains, steam pipes, condensate systems, sewage and fire suppression equipment, and HVAC systems. Representative recent awards include a $96 thousand VA emergency repair for a Building 70 steam condensate pipe leak (June 2026), a $99 thousand VA watermain repair contract (April 2026), a $25 thousand VA emergency water main repair at the Milwaukee facility (March 2026), and a $26 thousand US Coast Guard emergency water main repair at Sector Lake Michigan (December 2024). Work is performed exclusively at federal facilities in the Milwaukee region and surrounding upper Midwest, with all contracts awarded on a firm fixed-price, time-critical basis typical of emergency facility maintenance.

The vendor operates as a 100% prime contractor across 98 total awards with zero subcontract activity. Activity has been episodic rather than growth-oriented — six awards in 2022, two in 2023, five in 2024, one in 2025, and three in 2026 — reflecting the lumpy, unplanned nature of emergency infrastructure repair work. Combined potential value across all historical awards stands at $1.8 million. Two awards (combined potential value $197 thousand) face ultimate completion within the next twenty-four months and therefore carry recompete exposure.

The vendor participates in several parent vehicles but primarily operates on task order against an indefinite delivery contract (Navy N6246700D7751) through which 15 task orders have been placed. SCI-reported invoicing of $154 thousand in FY2023 reflects a single prime contract scaled to roughly 0.7 FTEs; no SCI-reportable invoicing appeared in FY2022 or FY2024, indicating that most of API's federal work falls below the $150 thousand SCI reporting threshold — consistent with the $13 thousand to $99 thousand purchase order ceiling values visible across the award portfolio. Government-paid rates on SCI-reportable work ran at a median of $99.37 per hour, aligned with commercial mechanical systems labor in the Milwaukee market. API performs no subcontractor work internally and subcontracts no labor to other primes.

API's federal footprint is geographically and functionally concentrated: a local, full-and-open-competition mechanical contractor serving two primary federal customers (VA and Coast Guard) at Milwaukee-area facilities for emergency and time-critical infrastructure repair work that favors local presence and rapid response capability over size or SBA status.
