FAQs About Commercial Rooftop Units (RTU)

A rooftop unit or RTU is a complete, self-contained HVAC system installed on the roof of a commercial building. These units provide heating and air conditioning to the building and are designed to be a space-saving and energy-efficient choice for commercial spaces.

Is your commercial building lacking sufficient real estate for an HVAC unit appropriately sized to heat and cool your space? If so, a rooftop unit (RTU) may be the best option for your business. 

In addition to their space-saving benefits, RTUs offer:

  • Simplified installation and maintenance
  • Energy efficiency
  • Scalability 

A quarterly maintenance schedule is generally recommended for commercial rooftop units to ensure they continue to run efficiently and to catch any potential issues before they become a problem. A different schedule may be recommended depending on your industry and the environment your RTU services. Contact our team today for more information.

Yes! Our experienced team can assess your needs and recommend a customized solution for your commercial building. Whether you are looking for an RTU with variable-speed fans, a more energy-efficient option, advanced control systems, or more, the Heritage Systems Services team is here to help.

There are several signs that your RTU may be in need of repair or possibly replacement, including:

  • Unstable temperatures
  • Strange noises from the unit
  • Skyrocketing energy bills
  • Frequent repairs
  • The RTU has reached its typical lifespan of 15-20 years

If you are experiencing issues like these, contact Heritage Systems Services today to schedule a system assessment.
