Central Air & Heating Service

What Central Air & Heating Service does

Central Air & Heating Service (CAHS) is a commercial mechanical contracting company founded in 1972 in Harlingen, Texas, delivering HVAC, plumbing, and building automation/controls services across South Central Texas. The company operates a design-build, design-assist, and retrofit delivery model with in-house duct and pipe fabrication, 3D BIM scanning for existing-facility digitization, and 24/7 emergency service dispatch. Its core technology stack centers on mechanical engineering execution rather than software platforms — proprietary physical assets include windstorm-certified curbs, prefabricated duct/piping assemblies, and central plant construction capabilities for chillers, cooling towers, and utility infrastructure.

CAHS serves five primary verticals: K-12 education (Harlingen ISD, Brownsville ISD, La Joya ISD, Texas State Technical College), healthcare (McAllen Medical Center, Rio Grande Regional Hospital, Tropical Texas Behavioral Health), government (Cameron County Administration Building, Brownsville International Airport, Harlingen Border Patrol), industrial/food processing (Hello Fresh, United Foods, Honeywell), and commercial (Texas Regional Bank HQ). Revenue is generated primarily through project-based design-build installation contracts (one-time, custom-scoped) supplemented by recurring 24/7 service and maintenance subscriptions with dedicated account managers. Differentiated certifications — ASHE Certified Healthcare Constructor, ICRA-trained staff, OSHA 30 lifetime, SCIF-capable — position the company for specialized institutional and federal procurement vehicles.

Following acquisition by Pueblo Mechanical in 2023, CAHS became an operating company within Modigent, a national mechanical services platform backed by OMERS Private Equity. In 2025, CAHS co-located with sister operating company Climate Solutions in a new San Antonio regional hub, expanding its service area beyond the Rio Grande Valley into central Texas. The company is privately held, with revenue and headcount not publicly disclosed, and operates two physical offices (Harlingen HQ and San Antonio regional hub).
