Our AAON RN Series Services in Long Island City
Comprehensive maintenance, repair, and replacement for AAON's self-contained RN Series units — keeping Long Island City's commercial buildings running year-round.
Emergency AAON RN Series Repair
When your RN Series unit trips offline, our AAON-trained technicians reach Long Island City sites typically within 4 hours, stocked with genuine AAON components to resolve most failures on the first visit.
AAON RN Series Preventative Maintenance
Custom-scheduled inspections built around your unit's tonnage, filtration package, and economizer configuration — catching bearing wear, belt fatigue, and refrigerant drift before they cause downtime.
Controls & BAS Integration
We integrate RN Series units with 75F, Honeywell, or your existing BAS platform, unlocking demand-controlled ventilation and setpoint optimization that AAON's variable-speed drives are built to support.
LL97 Compliance Optimization
NYC's Local Law 97 targets buildings over 25,000 sq ft — exactly the class of Long Island City properties running RN Series rooftop fleets. We assess your carbon exposure and tune the units accordingly.
AAON RN Series Replacement & Retrofits
When a legacy RN Series unit reaches end of life, we handle the full replacement — engineering-grade spec, rigging and crane coordination, DOB filings, and startup commissioning.
Air & Water Test and Balance
Certified TAB reports confirm your RN Series system is delivering its designed airflow and capacity — documentation your Long Island City building manager needs on file for code and insurance purposes.
From breakdown to back online
One partner handles every step. Here's how we do it.
Same-day site assessment
You call, we respond. An AAON-trained technician reaches your Long Island City location within 4 hours, equipped with diagnostic tools and common RN Series parts to resolve most issues on the first visit.
Root cause diagnosis
We don't swap components until we understand the failure. A full diagnostic — electrical, refrigerant, mechanical, controls — identifies the real cause rather than masking a symptom that resurfaces next season.
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 AAON's OEM specifications, followed by a full startup and commissioning check — verifying airflow, refrigerant charge, and controls response before we leave the roof.
