They were quick to get out to a leak issue, inspect the problem and figure out exactly what needed to be done. Price was very reasonable and affordable. Joe and his team showed up on time, work was efficient and clean up was perfect! They were done in about 5 hours inspection and everything! I’m so glad this is done and our problem is solved. Will definitely use this company for future projects and refer to all family and friends. Thank you so much!

Commercial Rooftop HVAC FAQs

What is a commercial rooftop HVAC system?

A commercial rooftop HVAC system, also known as a rooftop unit (RTU), is a type of air conditioning and heating system that is installed on the roof of a commercial building. It combines all the components of a traditional HVAC system, including the compressor, condenser, evaporator, and air handler, into a single unit.

What are the advantages of a rooftop HVAC system?

Space-saving: Rooftop units free up valuable interior space by installing them on the roof.
Easier maintenance: RTUs are easily accessible for maintenance and repairs without disrupting building occupants.
Flexibility: Rooftop systems can be easily expanded or modified to accommodate changes in building layout or usage.
Energy efficiency: Modern RTUs offer high energy efficiency ratings, reducing operating costs.

How long do commercial rooftop HVAC units last?

With proper maintenance, commercial rooftop HVAC units typically last between 15 to 20 years. However, factors such as usage, climate, and maintenance practices can impact their lifespan.

How often should a rooftop HVAC unit be serviced?

It is recommended to have your rooftop HVAC unit serviced at least twice a year, once before the cooling season and once before the heating season. Regular maintenance helps ensure optimal performance, energy efficiency, and longevity of the equipment.

What are the energy efficiency ratings for rooftop HVAC units?

Energy efficiency ratings for commercial rooftop HVAC units include the Seasonal Energy Efficiency Ratio (SEER) for cooling and the Annual Fuel Utilization Efficiency (AFUE) for heating. Higher ratings indicate better energy efficiency. Current minimum standards are SEER 13 for air conditioners and 80% AFUE for gas furnaces.
