Commercial Warehouse HVAC Systems in Fontana

Why warehouses in Fontana choose #1 AC Guys

We specialize in large, complex commercial spaces across Greater Los Angeles and nearby communities such as Fontana. Our focus is performance: stable temperatures, cleaner indoor air, and lower total cost of ownership. As a 4th‑generation family of engineers with 80+ years in engineering, we bring an engineering‑first mindset to every decision—from load calculations and air distribution to controls and commissioning.

• Design/build and retrofits for high‑bay, large‑volume facilities
• Optimized airflow to address racking, mezzanines, and dock doors
• Energy strategies aligned with California Title 24
• Planned maintenance that prevents downtime and protects ROI

Systems we design, install, and optimize

Every warehouse has unique heat loads, infiltration challenges, and occupancy profiles. We engineer solutions that match your operations and automation.

• Rooftop packaged units (RTUs) with economizers for free cooling
• VRF heat recovery systems for zoned comfort and flexibility
• Dedicated Outdoor Air Systems (DOAS) and make‑up air units for balanced ventilation
• High‑efficiency heaters and destratification strategies to reduce stratification
• Demand‑Controlled Ventilation (CO2) for variable staffing and shift changes
• Advanced controls, VFDs, and smart sensors for precise management

We also correct underperforming systems: resizing equipment, rebalancing ducts, improving filtration and outside air intake, and adding controls that reduce short cycling.

Indoor air quality (IAQ) that supports healthy, productive teams

Healthy air is our mission. In high‑traffic warehouses, proper ventilation and filtration are critical for well‑being and productivity.

• MERV 13+ filtration strategies and zone‑based upgrades
• Source capture and pressurization to reduce dust migration
• UV‑C and other IAQ enhancements where appropriate
• Humidity and temperature control tuned to process needs

We align ventilation rates with occupancy, loading dock activity, and process exhaust to maintain clean, comfortable conditions throughout the workday.

Energy and compliance for California facilities

Our designs reflect California’s performance requirements and best practices. We help you plan with compliance in mind while improving efficiency.

• Title 24‑aligned controls, economizers, and ventilation
• Coordination for permits and inspections as required
• Support for CALGreen and local AQMD considerations
• Fire/smoke damper labeling and access provisions

The result is a system that not only meets code but also delivers measurable savings and consistent comfort across seasons.

Our engineered process

We use a disciplined approach to reduce guesswork and accelerate outcomes.

• Site walk and discovery: racking, docks, heat sources, schedules
• Load calculations and airflow modeling for high‑bay volumes
• Concept design with energy and IAQ options
• Final engineering, controls strategy, and phasing plan
• Commissioning, balancing, and documentation
• Proactive maintenance with performance reporting

You get a clear roadmap, transparent budgets, and a single accountable team from concept to turnover.

Preventive maintenance and rapid service

Planned maintenance keeps your warehouse operating smoothly. Our service programs include seasonal inspections, filter changes, coil cleaning, economizer checks, controls calibration, and performance benchmarking.

• Reduce breakdowns and extend equipment life
• Improve IAQ with the right filtration schedule
• Catch energy waste early with data‑driven checks

When issues arise, we mobilize quickly to restore critical comfort and ventilation, minimizing disruption to receiving, picking, and shipping.

Training and technical depth

Our engineers have trained at the factories of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). This direct exposure to manufacturer standards helps us deploy advanced split, multi‑split, and VRF solutions with high reliability and excellent commissioning outcomes.

Serving Fontana from Greater Los Angeles

We are a Los Angeles family business proudly serving Fontana and nearby Inland Empire logistics hubs, as well as Los Angeles County and surrounding areas including Orange County, Ventura County, and Western Riverside County. If your warehouse is expanding, consolidating, or undergoing a retrofit, we can help you plan an HVAC strategy that scales with your operations.
