AC PRO‑compatible specifications and sourcing

Prefer AC PRO components or consumables? We can build AC PRO‑compatible specifications and, upon request, source filters, coils, and other materials through AC PRO supply channels to meet your facility standards. Our focus is fit, function, and lifecycle value—so the system we deliver is easy to maintain and performs as designed over time.

Note: We do not claim dealership or endorsement; we simply support AC PRO‑compatible equipment selections when they align with your project goals.

Factory‑trained specialists for complex systems

Our commercial team is factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That training helps us solve the hard problems: uneven temperatures across floors, noise complaints in open offices, ventilation gaps after layout changes, and rising utility bills. We engineer solutions that address root causes—load, duct design, airflow balance, controls, and maintenance cadence.

Healthy air for a healthy life

Air quality is mission‑critical. We specify filtration levels that match your risk profile, optimize outdoor air to ASHRAE guidance, and implement smart schedules that reduce energy waste while keeping CO2 and particulate levels in check. The result is cleaner air, fewer hot/cold calls, and a more productive workspace.

Engineering first, sales second

Because we are a fourth‑generation family of engineers, our process is transparent and data‑driven:

• Site walk and condition assessment with photos and nameplate data
• Load calculations and ventilation analysis for right‑sized design
• Clear, code‑aware scope with options and lifecycle cost comparisons
• Clean installation with safety, documentation, and commissioning reports
• Training for your facility team and a simple, preventive maintenance plan

Rialto response you can count on

We dispatch quickly to Rialto and neighboring Inland Empire communities through our Western Riverside and Greater Los Angeles operations. Whether you need same‑day diagnostics, a temporary cooling plan, or after‑hours support, we mobilize fast and communicate clearly from first call to sign‑off.

Systems and applications we handle

• Open‑plan offices, private suites, and multi‑tenant buildings
• Server rooms and spot cooling for heat‑dense zones
• Conference rooms with variable occupancy and CO2 control
• Lobby and common areas with noise and comfort constraints
• Parking and ancillary areas with ventilation needs

We work across VRF/VRV and ductless solutions by Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier, along with high‑efficiency heat pumps and rooftop units engineered for California climates.

Preventive maintenance built for offices

A well‑maintained system costs less to own. Our office‑centric PM programs include seasonal tune‑ups, filter schedules aligned with occupancy and IAQ targets, coil cleaning, electrical checks, refrigerant and airflow verification, and proactive repair planning. You’ll see fewer breakdowns, better comfort, and predictable budgets.

Compliance and documentation

We provide code‑ready paperwork, cut sheets, commissioning records, and balancing reports to streamline approvals and protect your investment. Expect professional documentation that facility managers, owners, and inspectors appreciate.
