American Chiller Service, Inc.

American Chiller Service, Inc., a for-profit Subchapter S Corporation based in Rancho Cordova, California, provides commercial HVAC system installation, maintenance, repair, and emergency support to federal facilities as a prime contractor (98% of recent awards) competing on full-and-open solicitations with no set-aside designations across its footprint.

American Chiller Service operates in the commercial refrigeration and HVAC repair space, grounded in NAICS 4217 (Plumbing, Heating, and Air-Conditioning Contractors), with secondary work in HVAC equipment manufacturing and facilities support. The vendor's concrete service portfolio spans chiller unit replacement and installation, cooling tower maintenance and repair, compressor block service, emergency HVAC repair with rapid-response commitments, preventative maintenance contracts, and temporary HVAC equipment rental. Representative prime work includes a $317,819 definitive contract with the United States Mint to replace and install chiller units at the San Francisco facility (awarded September 2024, completed October 2025); a $107,190 firm-fixed-price purchase order from the Department of Veterans Affairs to replace cooling tower fill media at a Reno facility (May 2023); a $105,650 delivery order from the Department of Agriculture's Agricultural Research Service under the GSA Multiple Award Schedule for HVAC cooling tower repair and upgrade at Parlier, California (February 2022); and a five-year purchase order from the U.S. Fish and Wildlife Service Region 8 valued at $61,650 for annual maintenance and repair of the SMARDT chiller control system at Nevada's Lahontan National Fish Hatchery, with bi-annual preventative maintenance and one-hour emergency response requirements (awarded August 2023, extending through September 2028).

Customer concentration is pronounced. The top five customer agencies account for 50% of recent awards by count. Veterans Integrated Service Network 21 (the Veterans Health Administration's regional operation) dominates with 40 awards and $3.4 million in combined potential value — nearly double the next-ranked customer. By potential value dollars, VISN 21 anchors 34% of all combined value, followed distantly by the Air Force Air Mobility Command (4 awards, $1.6 million), the National Oceanic and Atmospheric Administration (13 awards, $645 thousand), the Defense Commissary Agency (5 awards, $633 thousand), and the United States Mint (2 awards, $416 thousand). The vendor serves 35 distinct federal customer agencies across a 30-year history, but activity is declining: from eight awards in 2022 to two each in 2024 and 2025, with only one award in 2026 to date.

American Chiller Service holds a seat on the GSA Multiple Award Schedule, with 44 task orders generating $3.7 million in combined potential value. The vendor also places work under Blanket Purchase Agreement V261P0182 (3 task orders, $283 thousand) and an indefinite-delivery contract (2 task orders). The recompete exposure is minimal — only one award completing within the next twenty-four months, with $107 thousand in combined potential value.

Subcontracting activity is negligible (2% of awards): the vendor delivered chiller control board services to Bering Global Solutions on a sub task and annual eddy current testing and leak-check services on five Trane chiller units to Preventive Maintenance Services Company under a BPA call at the Ronald V. Dellums Federal Building (awarded May 2023, performance period March 2023 through February 2025).
