What Is an RTU?
An RTU (rooftop unit) is a packaged commercial HVAC system installed on the roof of a building. These self-contained systems typically manage heating and cooling for:
- Restaurants
- Retail stores
- Warehouses
- Office buildings
- Government facilities
- Multi-tenant commercial properties
RTUs combine heating and cooling components in one cabinet and distribute conditioned air through ductwork. Because they serve entire spaces, downtime impacts comfort, staff productivity, and customer experience quickly.
