What is an RTU Unit?

Property owners have a lot on their plates when it comes to maintaining a building, and effective heating, ventilation and air conditioning (HVAC) is a priority for any well-functioning property. A key component that can often fulfill this need is a rooftop unit, better known as an RTU. But what is an RTU unit, and why should property owners consider it for their buildings? Van Drunen Heating & Air Conditioning helps answer these questions and more. 

What is an RTU?

An RTU, or Rooftop Unit, is a compact and self-contained HVAC system installed on the roof of a building. Unlike traditional HVAC systems that take up interior space, RTUs are designed to manage heating, cooling and ventilation efficiently from above. 

Components of an RTU

RTUs generally include the following components: 

• Compressor: Responsible for pressurizing the refrigerant to cool or heat air. 
• Fan: Helps circulate air throughout the building. 
• Condenser Coils: Aid in transferring heat for efficient climate control. 
• Filters: Maintain clean airflow by trapping dust and particles. 
• Economizer (optional): Brings in fresh outdoor air, improving energy efficiency. 

How Do RTUs Work?

RTUs intake air from the outdoors, heat or cool it based on the building’s requirements, and distribute it through the property’s ductwork. Once the air has circulated through the rooms, it is sent back to the RTU, where the process begins again. 

What Are the Benefits of RTU Units?

RTUs offer several key advantages, making them an excellent option for commercial property owners who want both functionality and efficiency. 

1. Space-Saving Design

Because RTUs are installed on the roof, they free up valuable indoor space that would otherwise house HVAC equipment. For property owners, this means more room for tenants, inventory, or operational needs. 

2. Energy Efficiency

Many RTUs come with energy-efficient features, such as economizers or advanced thermostatic controls. These functions help reduce energy consumption while still maintaining a comfortable indoor environment, leading to lower utility bills. 

3. Cost-Effectiveness

RTUs simplify heating and cooling operations in a single unit, reducing installation and maintenance costs. Their durability also helps property owners avoid frequent replacements or repairs, saving money in the long run. 

4. Easy Maintenance

Positioning the unit on the roof keeps it out of daily operations, while its accessible components make periodic maintenance and troubleshooting simple for professionals. 

Suitable Buildings for RTU Units

RTUs work exceptionally well for low-rise commercial buildings where rooftop installation is practical. They are often used in spaces like:

• Restaurants where maintaining a comfortable indoor temperature is essential for both diners and cooks. 
• Warehouse Facilities that need large-scale temperature control. 
• Retail Stores and Supermarkets where efficient air distribution spans wide open spaces. 

However, RTUs are not recommended for taller structures such as high-rise buildings. The height can complicate rooftop access and impact their efficiency in serving multilevel spaces. 

Maintenance and Accessibility

Regular upkeep is crucial to keeping an RTU running effectively. Routine maintenance tasks include cleaning filters, inspecting refrigerant levels and checking for wear and tear. Since RTUs are roof-mounted, proper and safe roof access is paramount for ongoing service and repairs. 

Installation and Compatibility

One of the greatest benefits of RTUs is their compatibility with existing ductwork in most buildings. Installation is relatively straightforward, and when done by experienced professionals, it causes minimal disruption to the property’s operations. Experienced HVAC companies like Van Drunen Heating & Air Conditioning ensure the process is efficient and stress-free. 

Why RTUs Are a Smart Choice

Choosing an RTU for your building combines convenience, efficiency and cost savings in one system. For property owners keen on reducing operational headaches while improving climate control, RTUs are a compelling option.
