What is an RTU?

Apr 15, 2021 | RTU - Rooftop Units

While you already might be familiar with an HVAC unit, the term RTU may still be confusing. A lot of people ask the question, what is an RTU HVAC?

The answer is quite simple! RTU is an abbreviation for rooftop units. It’s easy enough to guess that this is essentially HVAC equipment that goes on the roof. RTU systems are becoming increasingly more popular, especially in commercial use.

If you’re in the market for an HVAC unit, you’re probably receiving several recommendations to buy an RTU. However, before you make a decision, it’s important to understand the differences between an RTU and a traditional unit.

What Parts Make Up an RTU HVAC?

Before you purchase an RTU HVAC, it’s important to know what parts make up the machine. Your typical RTU is a rectangular machine that has parts assembled adjacent to each other on the inside. On the outside is a metal casing.

Air Hood

On one side of the unit, you’ll notice the presence of an air hood. The purpose of an air hood is to allow outside air to enter. The air is then warmed or cooled depending on the settings and is then distributed inside the building.

Dampers, Filter, and Coils

Once the air enters through the hood, it makes its way to the dampers. These are rotating metal sheets that help prevent air from escaping. They can also potentially run at different speeds to control how much air enters. These dampers are also what cool the air when necessary and heat the air as well!

The air then went through the filter and distributed to different areas of the building via the fan!

How is an RTU Different From Other HVAC Systems?

RTUs are also known as package units in the industry. They are set apart from the traditional split systems because they house all the machinery in one box. The unit sits on top of the roof and connects directly to the building’s ventilation system.

There are certain advantages to investing in an RTU over traditional HVAC systems. Here are a few benefits of using an RTU system.

Use Less Energy

One of the biggest advantages of using an RTU HVAC system is that it takes less energy. The units are assembled to provide optimal performance and remain efficient at the same time. As a result, you’ll get lower utility bills.

No Indoor Space

As the RTU is placed on the roof, it doesn’t take up any indoor space.

The RTU HVAC systems already come assembled from the factory; that’s why it costs less and takes less time to set them up, and a good HVAC company like Shriver can do it quickly.
