For cooling and heating systems to be installed in commercial buildings, you need a large space. The HVAC system may be placed to the side of the back of buildings. This solution works well if you have enough space. However, it does not take into account a simpler solution: placing an HVAC roof unit on the top of your building.

What’s an HVAC Rooftop Unit, and How Does It Work?

HVAC rooftop units (RTUs) are common heating and air conditioning systems. These units are small and compact. They are often called a “package unit”, as the whole HVAC system is contained in one unit. RTUs are often used on the roofs of shops or small commercial buildings. They deliver conditioned air through air ducts to the designated areas.

What is it like other commercial HVAC Systems?

RTUs differ from other HVAC units as they don’t split system components in different places around the building. Rooftop units are a type o Air Handling Unit. The main difference is that they are smaller and can be installed on the roof. Rooftop units have been designed to be weatherproof and more robust so they can withstand the elements like rain, snow, wind, sun, and even snow. Because they are fully self-contained rooftop units, external chillers and boilers are not used to heat or cool them.

HVAC rooftop units can be packaged with all parts in one unit. This distinguishes it from conventional units that are divided into indoor and outside units. A rooftop HVAC platforms unit can provide many benefits for your building, including a lower installation cost.

Energy-efficient HVAC system

Additional controls include energy-saving features. Air volume control, dampers, energy recovery wheels, and air volume control all help to improve the HVAC’s efficiency. A thermostat that can be controlled by an automatic controller allows for the synchronization between operation and seasonal changes.


Modular rooftop HVAC units allow you to adapt to changing building needs. Based on the heating needs of your building, you can add an air conditioner module to replace one or take out an older one. The set-up can be modified without the need to replace the entire system.


The HVAC system is placed on the roof to deter theft and vandalism. The mechanism is protected from dust, dirt, and other debris. It also reduces the need to maintain the air conditioner.

Optimized area

Rooftop air conditioners can be mounted on the roofs of buildings. This is a great way for businesses to save space. Many rooftop HVAC systems can be moved around to accommodate different roof sizes.

While air conditioners are an essential business asset, indoor units can take up much more space than necessary and may cause more intrusion than their value. Rooftop air conditioners help reduce noise pollution and make it more comfortable for customers. Rooftop

Less noise pollution

HVAC systems that are used commercially require a specific setup. It must emit extreme noise. The rooftop location reduces unwanted sounds entering the building.

Improved Durability

Being a business owner can be difficult. Your business must manage staff, finances, and clients. You have enough responsibilities to worry about the air conditioner. Rooftop HVAC systems make it easy for busy business owners to maintain their units.

Rooftop air conditioners also have less exposure to dust and dirt than units at ground level. As such, they are less likely to sustain accidental damage due to dirt buildups. Because they are difficult to reach, they are also less likely to be vandalized or stolen. Rooftop HVAC units should be serviced annually. But, because they are not within your business, a technician will be able to fix any issues quickly.
