AC PRO Commercial Boiler Installation in Fontana, CA

As a Los Angeles–based, family‑owned HVAC engineering firm, #1 AC Guys brings deep hydronic expertise to Fontana’s commercial properties. We specialize in AC PRO commercial boiler installations that deliver efficient, even heat with outstanding indoor air quality—ideal for offices, healthcare, education, hospitality, manufacturing, and multifamily common areas. Our mission is healthy air for healthy living, and hydronic heat supports that mission with quiet, dust‑free comfort.

Design‑Build Expertise You Can Measure

Every building is unique. We perform detailed heat‑load analysis, pump head calculations, and distribution design to ensure the boiler plant is precisely matched to your loads. Our engineers optimize primary‑secondary or variable primary flow, specify VFD pumps, and plan piping to reduce air binding and cavitation while maximizing condensing efficiency where applicable.

• Right‑sizing to eliminate short‑cycling and premature wear
• Low‑NOx solutions compliant with SCAQMD for the Inland Empire region
• Title 24 documentation and energy modeling support
• Controls integration with existing BAS (BACnet, Modbus)
• Seismic anchorage per California Building Code for Fontana inspections
• Balanced hydronics: air separators, expansion tanks, and dirt separation

We install AC PRO commercial‑grade boilers and supporting hydronic components with clean, serviceable layouts—clearances respected, valves labeled, and instrumentation placed for accurate diagnostics.

Our Fontana Commercial Boiler Installation Process

• Assessment & Scope: Site survey, existing plant evaluation, and risk plan to minimize downtime.
• Engineering & Submittals: Load calcs, equipment selections, drawings, Title 24, and permit package.
• Procurement: Timely sourcing of AC PRO boilers, pumps, vents, controls, and water treatment.
• Installation: Demolition, rigging, pipefitting, flue/condensate, gas line, electrical, and controls.
• Commissioning: Factory‑recommended checks, gas combustion tuning, sensor calibration, and flow balance.
• Handover: O&M manuals, owner training, warranties, and a preventive maintenance plan.

Need a weekend or overnight cutover? We phase changeouts, provide temporary heat when required, and coordinate with your GC or facilities team to protect operations.

AC PRO Equipment Options

From non‑condensing workhorses to high‑efficiency condensing models, AC PRO solutions can be configured for single‑boiler or staged plants with lead‑lag controls. We match heat exchangers, venting materials, and water treatment to your water quality and duty cycle to extend life and maintain efficiency.

• Condensing boilers for high return‑water efficiency
• Staged systems for redundancy and part‑load savings
• Integrated outdoor reset and BAS connectivity
• VFD pumps and ECM motors for reduced electrical use

Our team is factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Hier (China). This background strengthens our controls, diagnostics, and integration skills across complex mechanical systems.

Safety, Code, and Environmental Compliance

We design and install to California Building Code, mechanical and plumbing codes, and applicable City of Fontana requirements. We plan for combustion air, venting clearances, condensate neutralization (for condensing systems), and gas pressure stabilization. Low‑NOx strategies align with South Coast AQMD rules for cleaner operation.

• Seismic bracing and anchorage
• Pressure relief discharge routing and labeling
• Backflow prevention and makeup water control
• Flue materials and clearances per listing
• Combustion analysis and documentation at start‑up

Water treatment is non‑negotiable for longevity. We specify chemical treatment or filtration to curb scale and corrosion, supported by side‑stream filters and dirt separators to protect pumps and heat exchangers.

Industries We Serve in Fontana & Greater LA

• Office and medical buildings
• Schools, campuses, and places of worship
• Industrial and logistics facilities
• Hospitality and retail centers
• Multifamily common areas and amenities

Whether you operate a distribution center near I‑10 or manage a mid‑rise on Sierra Avenue, our team tailors a boiler plant to the realities of your site, schedule, and budget.

Signs It’s Time to Upgrade

• Rising gas/electric spend and frequent lockouts
• Uneven heat, noisy operation, or short‑cycling
• Corrosion, leaks, or obsolete controls
• Inability to meet current low‑NOx or Title 24 standards

Proactive replacement preserves uptime, improves comfort, and can unlock energy savings that shorten payback. We provide clear ROI analyses so you can make confident decisions.
