Engineers for Complex Mechanical Rooms

Big and complicated projects are our specialty. Our four‑generation team leverages 80+ years of engineering experience to untangle legacy piping, mixed‑temperature loops, primary/secondary arrangements, and cascaded high‑efficiency boilers. We routinely stabilize systems with short cycling, temperature swings, nuisance lockouts, and uneven heating—restoring reliability while lowering energy spend.

Our engineers are trained at manufacturer facilities of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). That background sharpens our troubleshooting on modern controls, variable speed pumping, and advanced heat exchange—skills that translate into faster repairs and longer system life.

Healthy Air and Safer Buildings

Our mission is healthy indoor air for a healthy life. Properly maintained boilers help reduce airborne dust compared to forced-air heat, while correct combustion and ventilation protect occupants from combustion byproducts. We verify draft, combustion, and ventilation, and tune burners to support cleaner operation and better indoor environmental quality.

Our Repair Process

• Assessment: We arrive prepared, review recent faults, alarms, and maintenance logs, and perform targeted diagnostics.
• Root-cause diagnosis: Using instrumentation and system schematics, we isolate the true cause—controls, hydraulics, gas supply, or mechanical wear.
• Clear options: You receive a transparent estimate with repair paths, timelines, and risk considerations.
• Precision repair: We execute code‑compliant work, verify combustion, calibrate controls, and balance flow.
• Performance validation: Post‑repair testing confirms stable operation, efficiency, and safety.
• Prevention plan: We recommend adjustments or maintenance to minimize future downtime.
