In simple terms, commonly used systems include RTUs (rooftop units), split systems, mini-split systems and solar HVAC. Rooftop units are self-contained packaged systems that are located in weatherproof casing and installed on a commercial building’s roof. Split systems are a lot like residential central HVAC units but are contained to the building’s ductwork. Mini-split systems are slightly newer to the U.S. and are ductless heat pump systems that take up less space and are 30% more effective than ducted HVAC systems. Solar HVAC utilizes solar panels to harness the sun’s energy and convert it into power for heating and cooling.
This depends on many factors and there isn’t a definite answer, but usually, commercial systems can last about 20 years with appropriate routine maintenance.
According to the Air Conditioning Contractors of America (ACCA), the proper sizing and design of commercial HVAC systems like air conditioning systems relies on considering four distinct elements:
Application: Is the building an office, restaurant, grocery store or retail outlet?
Building Type: Is the space a single-story building, multistory building, a warehouse or another building type?
Square Footage: What is the size of the space to be heated or cooled?
HVAC Equipment Type: Does the building use gas or electric heat? Will it be a water-cooled or an air-cooled system?
