Commercial & Industrial Systems

Rooftop packages, make-up air, exhaust and ventilation, cooling towers and critical cooling for retail, office, warehouse and plant facilities. This is the core of what American Air Control does every day.

Every service in this category

Our primary focus

Rooftop & Package Units

Package units are the backbone of most commercial buildings in the Inland Empire, and they take the worst of our summers. We install, change out and repair RTUs of every tonnage, including crane sets, curb adapters and fabricated transitions when the new unit does not match the old footprint.

Make-Up Air Units (MAUs)

Commercial kitchens, plants and shops that exhaust hard need air put back, or the building fights itself: doors that will not open, hoods that will not capture, heat that will not hold. We install and service make-up air units and balance supply against total exhaust so the building runs at the pressure it was designed for.

Cooling Towers & Process Cooling

Towers are maintenance equipment, not install-and-forget equipment. Scale, corrosion and a dirty basin will cost you capacity long before anything fails outright. We clean, rebuild and service towers, heat exchangers and process loops, and we coordinate with your water treatment program instead of working around it.

Server Room & Critical Cooling

Server rooms, IDF closets and equipment rooms carry a constant load and no tolerance for downtime. We size and install dedicated cooling with redundancy where it matters, add temperature alarming, and put those rooms on a maintenance interval so a Saturday failure never becomes a Monday outage.
