Our rooftop unit went down on a Friday afternoon in August with a full dining room. They answered, showed up that evening, and had it running before close. No inflated emergency pricing, just a straight explanation of the failed part.

Mechanical systems
that stay running.
American Air Control installs, services and maintains HVAC across Riverside and Orange County: rooftop packages, make-up air, cooling towers, server rooms, mini-splits and full residential systems. Diagnosed right the first time, documented, and built for the way your building actually runs.
01 / Who we work for
Three kinds of buildings.
One standard of work.
Our focus is commercial and industrial mechanical work, and we bring that same discipline into homes. Nothing gets left out, and nothing gets treated as a template job.

Commercial
Retail, office, restaurants and multi-tenant buildings. Rooftop packages, splits and controls kept on a maintenance interval so your tenants stay comfortable and your call volume stays down.
- /Package unit change-outs
- /Scheduled maintenance
- /Controls & economizers

Industrial
Warehouses, plants and distribution centres. Make-up air, exhaust and ventilation, cooling towers, process cooling and heavy equipment change-outs handled end to end, including crane sets.

- /Cooling towers & process loops

Residential
Full system replacements, mini-splits, heat pumps and ductwork done clean and left clean. Straight answers about what your house actually needs. No one-size-fits-all quote, no upsell pressure.

03 / Why American Air Control
Diagnosed right.
Not guessed at.
“We work with our customers for what their individual needs are, situation by situation. Nothing is one size fits all. We maintain our training and certifications so we diagnose faster and more accurately, and we keep the back end moving so a repeat service call never lands on your invoice.”
Trained, then trained again
NATE and NCI certifications kept current so we diagnose faster and more accurately, and you pay for the actual problem.
Specced to your building
Load, space and how you really run the building drive the recommendation. Nothing is one size fits all.
Parts and logistics handled
We keep the back end moving and order ahead, so a missing part does not turn into a second service call.
No upsell pressure
We are not here to sell you equipment you do not need. If a repair is the right call, we say so.

04 / How a job runs
A clear scope before a single tool comes off the truck.
Site walk & load review
We come out, look at the equipment, check access and take the readings that tell us what is actually happening.
Written scope & price
You get the scope in writing (equipment, work, and what is excluded) before anything is ordered or started.
Install or repair
Crews, cranes and permits coordinated around your operating hours. Nights and weekends when the building needs it.
Documentation & maintenance
Start-up readings, commissioning notes and a maintenance interval so the system keeps performing after we leave.
Certified & credentialed
The paperwork behind the work.
Licensed by the California Contractors State License Board, EPA Section 608 certified for refrigerant handling, and continually certified through NATE and the National Comfort Institute, because accurate diagnosis is a trained skill, not a guess.
NATE Certified
NCI Certified05 / Proof of work
Real jobs. Real rooftops.






06 / What customers say
Straight answers, twice as fast.
We had two other bids telling us to replace all four package units. American Air Control walked the roof, showed us readings on each one, and replaced the two that actually needed it. Saved us a serious amount of capital.
Clean install, clean job site, and they walked me through the whole system afterward. The mini-split in our upstairs addition finally makes that room usable in the summer.
They put our server room on a maintenance schedule and added a temperature alarm we did not know we needed. Zero cooling incidents since. Communication is excellent every visit.
