Professional Packaged Rooftop Unit Service in The Bronx

Rooftop HVAC units work hard year-round to heat, cool, and ventilate Bronx buildings. When a packaged unit stops working properly — whether it’s blowing warm air, not cooling, leaking water, or making loud noises — it can disrupt daily operations fast. Air Duct Co LLC provides expert rooftop unit repair, diagnostics, and maintenance for commercial properties, offices, retail spaces, restaurants, and multi-unit buildings.

Our technicians service all packaged units including Carrier, Trane, Lennox, York, Daikin, Goodman, and Rheem. From small rooftop units on mixed-use buildings to large commercial RTUs, we handle everything from electrical issues to coil cleaning, airflow problems, defrost issues, and refrigerant repairs.

How Packaged Rooftop Units Work — And What Causes Breakdowns

Packaged rooftop units operate as a self-contained HVAC system, handling cooling, heating, and air circulation for large spaces. Because the entire system sits on the roof, it’s exposed to heat, cold, rain, debris, and long run times — especially in a high-demand area like The Bronx.

Inside every RTU, several components work together:

  • The refrigeration circuit that cools the air

  • The heating section (gas or electric)

  • The blower and distribution system

  • Electrical boards and control modules

  • Safety sensors, drain system, and dampers

When even one component becomes stressed or dirty, the entire unit struggles.
Common triggers for RTU failure include:

• Outdoor exposure — Bronx weather, rooftop dirt, and construction debris wear equipment faster than indoor systems.
• Long daily run times — Businesses operate 8–16 hours a day, pushing rooftop units harder than residential systems.
• Poor airflow — Dirty coils or clogged filters reduce performance and raise energy costs.
• Electrical strain — Older buildings often have voltage fluctuations that damage rooftop units.
• Lack of scheduled maintenance — Most RTUs are out of sight, out of mind… until they fail.

At Air Duct Co LLC, we evaluate how the entire rooftop system is performing — not just one part — to deliver long-lasting, reliable repairs.
