Our Trane RTU Services in Brooklyn
Comprehensive maintenance, repair, and replacement — keeping your Trane rooftop units running year-round across Brooklyn's commercial buildings.
Emergency Trane RTU Repair
When your Trane unit goes down, every hour costs you. Our certified technicians reach Brooklyn sites typically within 4 hours, fully stocked to diagnose and repair on the first visit.
Trane RTU Preventative Maintenance
Custom maintenance plans starting from $396/year — designed around your specific Trane units, building load, and NYC seasonal demands. Catch failures before they happen.
Trane Controls & Tracer Integration
We integrate Trane rooftop units with Tracer and third-party BAS platforms, unlocking scheduling, economizer optimization, and fault detection Trane's controls are built to support.
LL97 Compliance Optimization
NYC's Local Law 97 targets buildings over 25,000 sq ft — exactly where most Brooklyn Trane RTU systems live. We assess your carbon exposure and implement HVAC-side solutions that reduce fines.
Trane RTU Replacement & Retrofits
When repair no longer makes economic sense, we handle full Trane RTU replacement — engineering-grade spec, NYC DOB filings, and startup commissioning included as standard.
Air & Water Test and Balance
Certified TAB reports delivered post-service, confirming your Trane system meets design specifications and satisfies NYC building code — documentation your building manager needs on file.
From breakdown to back online
One partner handles every step. Here's how we do it.
Same-day site assessment
You call, we respond. A certified Trane technician reaches your Brooklyn location within 4 hours, equipped with diagnostic tools and common RTU parts to resolve most issues on the first visit.
Root cause diagnosis
We don't replace parts until we understand the failure. A full diagnostic — electrical, refrigerant, mechanical — identifies the real cause rather than masking symptoms that resurface later.
Fixed-price proposal
Before a wrench turns, you receive a clear, itemized quote with no hidden line items. What we quote is what you pay — we absorb any unintended costs.
Certified repair & commissioning
Factory-certified technicians execute the repair to Trane's OEM specifications, followed by a full startup and commissioning check — verifying airflow, refrigerant charge, and performance before we leave the roof.
