PROJECT EXPERIENCE
Commercial & Industrial Projects
Althoff Industries works with facility owners, property managers, general contractors, and project partners throughout Chicagoland to deliver coordinated HVAC, plumbing, electrical, piping, sheet metal, building automation, and renewable energy projects. Explore examples of the types of work our teams support.
High School | North Shore, Illinois
1 MW Rooftop Solar Installation
Althoff Industries installed a 1.01 MW rooftop solar system across multiple roof elevations while the active school remained fully operational. Detailed logistics, lift planning, and coordination among multiple union trades allowed the project to be completed safely and on schedule.
Medical Office Building | Oak Park
Medical Office Building Rooftop Unit Replacement
Althoff Industries replaced four 90-ton rooftop units serving an occupied medical office building. Work was completed over two consecutive weekends to provide four new systems without disrupting the facility’s normal business operations.
Mixed-Use High-Rise | Downtown Chicago
High-Rise Sanitary Pipe Rehabilitation
Althoff Industries partnered with NuFlow Midwest to rehabilitate deteriorated sanitary piping inside an occupied 60-story high-rise. The combined lining and selective replacement approach restored the piping while avoiding extensive demolition and disruption to commercial and residential occupants.
Temperature-Controlled Storage | Northwest Suburbs
Critical Facility Standby Generator
Althoff Industries installed a 175 kW standby generator and automatic transfer switch to protect critical refrigeration and freezer operations. Careful prefabrication and cutover planning limited the facility’s final power interruption to approximately two hours.
RESTAURANT | CHICAGO’S GOLD COAST
Tankless Water Heater System Conversion
Althoff Industries replaced two aging domestic water boilers with six tankless water heaters, using staged isolation and system overlap to maintain hot-water service and keep the restaurant operating throughout the project.
Country Club | McHenry
Country Club Heating & Domestic Water Upgrade
Althoff Industries replaced aging heating and domestic-water equipment with two new boilers and a heat exchanger. Careful multi-trade coordination delivered a clean installation within a compact mechanical room while minimizing downtime.
