Commercial Boiler Installation in Fontana, CA

In Fontana’s industrial and logistics-driven environment, heat is mission-critical. #1 AC Guys delivers commercial boiler installations that combine efficiency, emissions compliance, and durability — engineered for long run hours and peak reliability. Our mission is simple: healthier, safer indoor environments for your teams and customers, supported by precision-built mechanical systems.

Systems We Design and Install

• High-efficiency condensing hot-water boilers for maximum fuel savings and low-NOx performance
• Non-condensing and copper-fin boilers where return water temperatures or budget require
• Modular and cascaded plants for redundancy, scalability, and high turndown
• Steam boilers and clean steam solutions for process, sterilization, and humidification
• Complete hydronic packages: pumps, separators, expansion, low-loss headers, venting, water treatment

Every installation is right-sized using load calculations, diversity factors, and real operating profiles — not rules of thumb. This reduces short cycling, improves comfort, and extends equipment life.

Our Proven Process

• Discovery and assessment: site survey, existing equipment review, and risk analysis
• Engineering and submittals: heat load, pump head, venting, gas train sizing, and controls architecture
• Code and compliance: Title 24, CalGreen, and South Coast AQMD low-NOx requirements
• Installation: pipefitting, flue systems, seismic bracing, gas, power, and controls integration
• Commissioning: combustion tuning, safety checks, water quality balancing, and performance testing
• Training and turnover: operator orientation, O&M documentation, and warranty registration
• Lifecycle support: preventative maintenance plans and 24/7 emergency response

We manage permitting and inspections end to end, coordinating with local authorities and utilities to keep your project on schedule and compliant.

Smart Controls and Integration

We integrate boilers with building management systems for optimal sequencing and monitoring. Features include outdoor reset, lead-lag rotation, demand-based staging, VFD pump control, and remote alarms. BACnet and Modbus connectivity allow seamless data sharing with your BMS for actionable insights and energy reporting.

Our team is factory-trained with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), bringing advanced HVAC controls and system-level expertise to every boiler plant. This holistic approach ensures the heating system works in harmony with ventilation and air quality goals.

Compliance and Safety

• Low-NOx solutions aligned with South Coast AQMD rules for Inland Empire facilities
• Title 24 documentation and acceptance testing support
• Seismic supports and anchorage per California requirements
• Combustion air, venting, and gas safety interlocks for safe operations

We also implement water treatment programs to protect heat exchangers, limit scale and corrosion, and maintain efficiency. Proper chemical dosing, filtration, and regular testing are built into our maintenance plans.

Upgrades That Pay Back

• Boiler plant optimization: high-turndown burners, outdoor reset, and condensing return strategies
• Hydronic improvements: primary-secondary piping, low-loss headers, and hydraulic separation
• Redundancy and resiliency: N+1 strategies to keep heat on during peak demand or service
• Flue and venting: Category II–IV venting, condensing drain management, and corrosion control
• IAQ alignment: proper ventilation and humidity strategies for comfort and health

Industries We Serve in Fontana

• Distribution centers and cold storage
• Manufacturing and light industrial
• Healthcare and medical offices
• Schools, campuses, and public facilities
• Hospitality, retail, and offices
• Multifamily and mixed-use buildings

Whether you are upgrading a legacy plant or designing a new facility, we execute complex scopes with minimal downtime. Night and weekend work windows are available to keep operations moving.

Service Area

We are a Greater Los Angeles family business serving Fontana and much of the Inland Empire by appointment, with regular coverage across Los Angeles County and nearby regions including Orange County, Ventura County, and Western Riverside County. If you operate multiple sites, we can standardize specifications and maintenance to simplify your portfolio.
