What Custom Air Products & Services, Inc. does

Custom Air Products & Services, Inc. (CAPS), founded in 1996 and headquartered at 35 Southbelt Industrial Dr. in Houston, Texas, is a privately held custom manufacturer and service provider of industrial and commercial HVAC equipment operating as an "ACS Brand." The company operates four divisions — Manufacturing, Mechanical Field Services, HVAC Service, and Parts — out of six Texas facilities totaling 300,000 sq. ft. Its core products include modular air handling units, air purification systems with UV-C and HEPA filtration, wall-mount air conditioners (2-40 tons), portable HVAC equipment (package units, chillers 30-500 tons, industrial heaters 75-150 kW), explosion-proof HVAC systems rated to NEMA 4, 4X, and 7, MCC/switchgear HVAC compliant with NFPA 496, chemical filtration scrubbers, and the proprietary EnergyGuard corrosion-resistant coating line. Notable technical differentiators include a modular framing system enabling sectional assembly through standard 3-foot doors for non-disruptive equipment replacement, in-house design-to-build capabilities spanning stainless steel, aluminum, and galvanized construction, and registered professional engineer design oversight.

CAPS generates revenue across five streams: custom equipment manufacturing (quote-based, one-time sales), HVAC service and repair (professional services, 24/7 availability), preventive maintenance contracts (recurring subscription), OEM parts distribution (hardware sales with global shipping), and exclusive distribution of Marvair and Industrial Climate Engineering (ICE) wall-mount products across Texas, Louisiana, Mississippi, and Alabama. Pricing is universally quote-based with no public disclosure. The go-to-market is enterprise field sales, backed by a 100+ specialty-equipped service vehicle fleet with GPS dispatch serving the United States plus international deployment. The customer base is concentrated in oil & gas, petrochemical, offshore energy, healthcare, and select commercial accounts, with named enterprise logos including Magellan Midstream, National Oilwell Varco, Powell Electrical, Intermountain Electronics, Memorial Hermann Health System, and Westin. Marketing is limited to a content-driven website, organic social (Facebook, X), video gallery, and an extensive testimonials page, with no disclosed advertising spend.

Broad incumbents

• Trane Technologies: Global commercial and industrial HVAC manufacturer offering chillers, air handlers, and applied systems. Overlaps with CAPS in commercial HVAC equipment, but Trane is a broad-line OEM versus CAPS' custom, hazardous-location specialty.
• Johnson Controls: Building systems incumbent offering York applied HVAC, controls, and service across commercial and industrial facilities. Competes with CAPS on packaged equipment and on service/maintenance contracts for larger accounts.
• Carrier Global: Major HVAC OEM with deep commercial, industrial, and refrigeration portfolios. Comparable on packaged cooling, air handling, and service; less focused on custom hazardous-location niche CAPS dominates.
• Daikin Applied: Applied HVAC arm of Daikin offering chillers, air handlers, and packaged equipment for commercial and industrial applications. Competes with CAPS on engineered HVAC projects and on service contracts for mid-to-large facilities.

Direct peers

• Modine Manufacturing: Specialty manufacturer of thermal management and heat transfer solutions for industrial and commercial markets, including hazardous-location and heavy-duty applications. Closest direct peer to CAPS in engineered industrial HVAC and explosion-proof cooling.
• Lennox International: Manufacturer of commercial and industrial HVAC equipment including refrigeration and applied systems. Overlaps with CAPS on light commercial/industrial packaged units and service, particularly in the Gulf Coast territory.
• Munters: Specialty provider of air treatment and climate solutions including industrial ventilation, humidification, and air quality systems. Directly comparable to CAPS on air handling, filtration, and engineered environmental control for industrial customers.
• Greenheck Fan Corporation: Leading manufacturer of commercial and industrial fans, dampers, louvers, and air-handling equipment. Comparable to CAPS in custom fabricated ventilation and air distribution products sold to contractors and engineering firms.
• AAF Flanders (American Air Filter): Global manufacturer of air filtration and air purification products for commercial, industrial, and cleanroom environments. Directly comparable to CAPS' air purification systems and HEPA/UV-C filtration offerings.

Emerging players

• CaptiveAire: Vertically integrated manufacturer and installer of commercial kitchen ventilation and HVAC. Comparable direct-to-customer field-service-plus-manufacturing model, though focused on foodservice versus CAPS' industrial/petrochemical mix.
