A rooftop unit (RTU) is a heating and cooling system installed at the top of a building. It’s ideal for commercial and industrial properties because it maximizes air conditioning and heating capabilities in large areas.
Since they’re placed on the roof, RTUs are great for saving valuable indoor space. They’re also conveniently located and built for trouble-free maintenance, ensuring the business below can run smoothly.
If you’re looking for a reliable, efficient, and space-saving solution for your facility’s climate control, consider an RTU. Cassell Brothers Home Services employs licensed, bonded, and insured technicians who provide comprehensive solutions.

Benefits of a Rooftop Unit
RTUs offer specialized benefits to commercial and industrial facilities, including:
- Their consolidated unit components allow for hassle-free maintenance and troubleshooting.
- They're located out of site and improve your building’s aesthetic.
- Some have additional heating components that enhance humidity regulation.
- They heat or cool large areas like factories, offices, etc.
- Some use 100% outdoor air, which is sent through a filter, ensuring fresher-than-normal air.
- They’re made with stronger materials than typical outdoor HVAC units, meaning they won't fail because of weather conditions.

Who Needs a Rooftop Unit?
Rooftop units are best for commercial buildings, especially those with larger spaces like warehouses or factories. They simultaneously provide superior cooling or heating levels while preserving that valuable indoor space.
RTUs are efficient and effective but may not be suitable for all buildings due to potential roof damage and vulnerability to severe weather. Before choosing an RTU, assess your roof’s integrity and consider your local climate to determine if it’s the right move for your building’s heating and cooling needs.
