Commercial Boiler Service and Repair — What We Do
Steam Tech covers the full lifecycle of your boiler system. Here's a breakdown of our core services:
Emergency and Scheduled Boiler Repair
When a boiler goes down, response time matters. Our technicians are dispatched around the clock throughout our service territory, arriving with diagnostic tools and stocked parts to diagnose and address problems fast.
- Wide Dispatch Coverage: We respond to service calls across Los Angeles, Orange, Riverside, and surrounding counties.
- Thorough Diagnostics: Leak detection, pressure testing, combustion analysis, and fault code review.
- On-Site Parts Replacement: Common components are carried on our trucks; specialty parts are sourced or fabricated quickly.
- Every Repair Includes a Written Report: You'll know what was fixed, what was found, and what to watch for next.
For high-capacity systems, we also handle industrial boiler repair for facilities with heavier demands.
Commercial Boiler Installation
Replacing an aging system or outfitting a new facility? Steam Tech manages the process from initial load calculations through final inspection and operator training.
- Right-Sized System Design: We calculate your facility's actual load requirements before recommending any equipment.
- High-Efficiency Options: Low-NOx burners, economizers, and modulating controls can reduce long-term fuel costs.
- Code-Compliant Work: All installations follow NFPA and applicable local standards—including AQMD requirements for Southern California.
- Full Project Management: We coordinate the work from start to finish so you're not juggling multiple contractors.

Temporary Boiler Rentals

- Skid-Mounted Trailer Units: Self-contained with controls, pumps, and safety devices already in place.
- Flexible Terms: Short-term and long-term rental contracts available depending on your timeline and budget.
- Performance Monitoring: Steam Tech tracks system performance throughout the rental period to keep the unit running reliably.

Frequently Asked Questions about Commercial Boilers

How often should I schedule preventive maintenance?
We recommend seasonal tune-ups (at least twice per year) to ensure safe, efficient operation and comply with insurance requirements. Regular service also allows technicians to catch developing issues before they turn into unplanned outages. For high-usage facilities, more frequent intervals may make sense depending on operating hours and system age.
What brands of commercial boilers do you service?
Our technicians work on all major manufacturers, including Cleaver-Brooks, Fulton, Hurst, Miura, Clayton, Babcock & Wilcox, and more. We carry diagnostic references for a wide range of makes and models, so brand rarely limits our ability to respond. If you're unsure whether your equipment is covered, call us before scheduling and we'll confirm.
Can you upgrade my existing boiler for better efficiency?
Yes—our solutions include burner retrofits, economizer installations, and control system upgrades to reduce fuel costs. In many cases, older commercial boilers can be meaningfully improved without a full replacement, which keeps upfront costs lower. Our technicians will assess your current system and give you an honest estimate of what upgrades are practical and what the payback looks like.
Do you also service industrial boiler systems?
Yes. Beyond commercial work, Steam Tech provides full-scope support for high-capacity industrial boiler services—including repair, installation, and ongoing service contracts. Our industrial clients include manufacturing operations, processing plants, and large-scale utility applications throughout Southern California.
What's included in a preventative maintenance program?
Steam Tech's maintenance visits are scheduled around your facility's operating calendar and cover the checks and adjustments your boiler manufacturer recommends to keep the system running safely and efficiently. Visit our industrial boiler preventative maintenance page for a closer look at what's included, or call us to discuss a plan tailored to your equipment.
