Commercial Boiler Installation in Los Angeles

Why choose #1 AC Guys for your commercial boiler project

We’re a Los Angeles family business in its 4th generation, backed by 80+ years of hands‑on engineering. Our mission is simple: healthier indoor environments and reliable comfort, delivered with craftsmanship and safety. We specialize in large and complex commercial projects—occupied retrofits, high‑rise plant upgrades, multi‑boiler lead‑lag systems, and mission‑critical facilities.

• Licensed, bonded, insured; safety‑first culture.
• Design‑build or plan‑spec delivery with transparent pricing and scheduling.
• Factory‑trained engineers (Fujitsu, Mitsubishi Electric, Midea, Gree, Haier) and experience integrating with major boiler and control OEM platforms.
• Seamless BAS integration (BACnet/Modbus), commissioning, and owner training.
• Turnkey permitting with LADBS and SCAQMD; Title 24 documentation included.

What we install and optimize

• High‑efficiency condensing hot‑water boilers (90–98%+), primary‑secondary or variable‑primary flow.
• Low‑NOx and ultra‑low‑NOx gas boilers to satisfy SCAQMD requirements.
• Modular/stackable boiler plants with intelligent lead‑lag sequencing.
• Traditional high‑mass and mid‑efficiency systems where appropriate.
• Steam boilers for process and humidification with proper DA tanks and traps.
• Electric and hybrid solutions for decarbonization initiatives.
• Pumps (ECM/VFD), heat exchangers, separators, expansion, and water treatment.
• Flue/chimney systems (Category II/IV), combustion air, and gas trains.

Design‑build engineering that pays off

Our process begins with a detailed site assessment and load analysis guided by ASHRAE standards. We right‑size capacity, model part‑load operation, and select equipment for seasonal efficiency—not just nameplate ratings. Expect stamped calcs where required, isometric piping, valve schedules, and clear submittals.

• Hydronic design: primary/secondary or variable‑primary with delta‑T targets.
• Pump head calculations, VFD selection, and air/dirt separation for longevity.
• Outdoor reset, supply temperature trimming, and lead‑lag staging to cut runtime.
• BAS integration: BACnet/Modbus, alarms, trending, and remote optimization.
• Flue and combustion design: materials, condensate neutralization, and drains.
• Seismic bracing, anchorage, and housekeeping pads per CBC and local amendments.

Los Angeles code, permitting, and compliance

We handle the maze so you don’t have to. From LADBS permits and inspections to SCAQMD compliance, your installation will be documented, tested, and ready for approval.

• Title 24 energy compliance and acceptance testing as applicable.
• SCAQMD Rule 1146/1146.1/1146.2 guidance for applicable sizes/emission limits.
• Low‑NOx/Ultra‑Low‑NOx burner selection and commissioning.
• Combustion analysis, start‑up reports, and owner O&M manuals.
• OSHPD/healthcare coordination where required and strict hot‑work protocols.

Industries and properties we serve

• Office towers, mixed‑use, and multifamily
• Hotels, hospitality, and entertainment venues
• Healthcare and labs
• Education and municipal
• Retail centers and warehouses
• Industrial/process and data facilities (process hot water/steam)

Project delivery and timeline

We minimize downtime with careful sequencing, prefabrication, and weekend or off‑hours changeovers. Typical timelines:

• Assessment & concept options: 2–5 business days.
• Engineering & submittals: 1–3 weeks, based on scope.
• Permitting & procurement: parallel path where feasible.
• Installation & start‑up: often 1–5 days for replacements; larger plants vary.

We coordinate crane picks, rigging, temporary heat, and tenant communications to keep your building operating.

Rebates, incentives, and budgeting

Our team helps you evaluate total cost of ownership with real numbers—fuel savings, maintenance, and lifecycle. Where available, we assist with utility rebates (e.g., SoCalGas programs), potential tax incentives, and documentation for sustainability goals and LEED strategies.

Maintenance, monitoring, and warranty support

A great installation deserves great care. We offer customizable preventative maintenance, water treatment, combustion tuning, and seasonal start‑ups. Ask about remote monitoring for alarms, runtimes, and efficiency trends. You’ll receive manufacturer warranty support plus our labor warranty, with clear SLAs for response times.

Healthy air and safer combustion

Our family’s mission is healthier indoor environments. Properly designed boilers improve comfort while protecting air quality with sealed combustion, correct venting, and verified CO/NOx performance. We add ventilation and monitoring strategies to complement your IAQ program.

Proudly serving Greater Los Angeles
