24/7 Emergency Packaged Rooftop unit (RTU) Repair
Commercial packaged rooftop units (RTU) operate in harsh rooftop environments, making them prone to mechanical fatigue, electrical surges, and coil corrosion. We maintain fully stocked service trucks stationed throughout New York City to resolve failures on the first visit.
Critical Diagnostic & Repair Capabilities for Packaged Rooftop Units (RTUs)
- Compressor Diagnostics & Overhaul: Acid-burnout testing, scroll/reciprocating compressor replacements, and crankcase heater testing.
- Refrigerant Leak Detection & Compliance: EPA Section 608 compliant leak detection, nitrogen pressure testing, system evacuation to 500 microns, and precise R-410A / R-32 charging.
- Blower & Air Movement Systems: Variable Frequency Drive (VFD) programming, static pressure balancing, fan shaft alignment, and heavy-duty drive belt tensioning.
- Economizer & Fresh Air Controls: Repair of stuck dampers, enthalpy sensor calibration, and actuator testing to ensure NYC Energy Conservation Code (NYCECC) compliance.
- Heat Exchangers & Gas Trains: High-sensitivity flue gas analysis, heat exchanger crack detection, spark ignition repairs, and gas valve adjustments.
Enterprise Preventative Maintenance Schedules
Unplanned commercial HVAC failure is significantly more costly than scheduled maintenance. Our service contracts are structured to keep your property compliant with NYC building codes, preserve manufacturer warranties, and optimize seasonal energy consumption.
| Inspection Scope | Comprehensive Tasks Completed Per Visit | Recommended Frequency |
|---|---|---|
| Airflow & Indoor Air Quality | MERV 13+ filter updates, blower wheel pressure washing, frame sealing, belt replacement, and pulley inspection. | Quarterly |
| Refrigeration & Coils | Chemical coil restoration (evaporator & condenser), superheat/subcooling calculations, and sight glass inspection. | Semi-Annually |
| Electrical Safety | Infrared thermography on wire connections, contactor point inspection, megohmmeter compressor testing, voltage/amp draw logging. | Semi-Annually |
| Combustion & Heating | Burner manifold cleaning, flue draft verification, limit switch testing, and heat exchanger inspection. | Pre-Heating Season |
| Economizer & Dampers | Fresh air intake adjustment, CO2 sensor calibration, outdoor air enthalpy sensor verification. | Pre-Cooling Season |
Turnkey Packaged Rooftop Unit (RTU) Replacement & NYC Logistics Management
If your rooftop HVAC system is over 12-15 years old, requires frequent repairs, or utilizes phase-out refrigerants like R-22, upgrading to a high-efficiency packaged unit (such as the Daikin Rebel ) can reduce facility energy usage by 30% to 50%.
Replacing an Packaged Rooftop Unit (RTU) in New York City requires precise engineering and regulatory clearance. We manage every step of the lifecycle internally without subcontracting vital planning.
Complete Replacement Process
- Engineering Load Calculations: Conducting Manual N thermal load calculations to ensure accurate tonnage and CFM delivery without short-cycling.
- Permitting & Agency Filings: Securing NYC Department of Buildings (DOB) work permits and environmental approvals.
- Street Closure & Crane Logistics: Managing NYC Department of Transportation (DOT) street closure permits, flaggers, crane setup, and safety rigging.
- Custom Curb Adapters: Measuring and fabricating heavy-gauge galvanized roof curb adapters for direct drop-in installation without altering structural roof decks.
- Ductwork & Electrical Hookup: Sealing supply and return plenum transitions, wiring main power connections, and integrating BMS controls.
- System Commissioning: Comprehensive TAB (Testing, Adjusting, and Balancing), refrigerant charge check, and sign-off documentation.
RTU Replacement & Local Law 97 Retrofits Single Building: Exceeds 25,000 gross square feet (GSF).
If your existing rooftop unit is over 15 years old, replacing it with a high-efficiency packaged rooftop unit or heat pump RTU is one of the most effective paths toward Local Law 97 compliance.
- Load calculations sized specifically for NYC commercial spaces
- Complete turnkey crane lifting, removal, and new packaged rooftop unit installation
- Integration with modern Building Management Systems (BMS) and Programable WIFI Thermostat.

Frequently Asked Questions (FAQ)
A commercial RTU should undergo comprehensive preventative maintenance at least twice per year—once before the heating season and once before the cooling season. High-traffic commercial properties, restaurants, medical offices, and warehouses benefit from quarterly inspections to ensure indoor air quality, maintain MERV 13 filtration, and satisfy NYC commercial building standards.
Yes. Replacing a commercial rooftop HVAC unit in NYC generally requires Department of Buildings (DOB) work permits, structural evaluations for roof curb load-bearing capacities, and environmental compliance documentation. Additionally, if replacement requires street closures for crane operations, Department of Transportation (DOT) permits are mandatory. Our team handles all permit filings internally.
The typical lifespan of a commercial rooftop packaged unit is 12 to 15 years. Due to NYC’s severe urban environment, salt-laden coastal air, and intense seasonal temperature shifts, unmaintained systems often fail around year 8 to 10. Routine preventative maintenance and chemical coil cleanings can help units reach or exceed the 15-year mark.
We service and install all major commercial packaged RTU brands, including Daikin, Carrier, Trane, York, Lennox, Rheem, and Goodman. Our engineers carry diagnostic software and direct replacement components for everything from light commercial 3-ton units to heavy industrial 50+ ton packaged systems.
The primary causes of emergency RTU failure include compressor burnouts from dirty coils, clogged economizers or stuck dampers, worn blower fan belts, refrigerant leaks, and failed VFDs or control boards. Routine seasonal tune-ups prevent up to 85% of these sudden mechanical and electrical breakdowns.
Modern high-efficiency RTUs (such as Daikin Rebel or Carrier WeatherExpert models) feature variable-speed inverter compressors and ECM fan motors that reduce energy consumption by 30% to 50%. Upgrading your RTU helps commercial property owners comply with local energy reduction mandates like NYC Local Law 97 while significantly lowering monthly utility costs.
Our 24/7 emergency repair service includes rapid dispatch within 90 minutes, comprehensive diagnostic testing (electrical, refrigeration, airflow, and combustion), emergency refrigerant leak containment, compressor swaps, and temp-control adjustments to restore building heating or cooling with minimal operational disruption.
When replacing an older RTU with a modern model, the footprint rarely matches the existing roof opening. Rather than executing costly structural roof modifications, we fabricate a custom heavy-gauge galvanized roof curb adapter. This transitions air supply/return channels perfectly and maintains a watertight seal without altering the roof deck.
An economizer is an automated damper system that pulls cool outdoor air into the building when ambient temperatures permit, offering “free cooling” without running the compressor. Under the NYC Energy Conservation Code (NYCECC), properly functioning and calibrated economizers are required on most commercial RTU systems to minimize building power consumption.
