Frequently Asked Questions about Commercial HVAC

How is commercial HVAC different from residential HVAC?

Commercial and residential HVAC systems share similarities but also have key differences:

• Size and Capacity: Commercial HVAC systems are usually much larger than residential systems to handle greater heating and cooling demands of bigger spaces.
• Complexity: Commercial HVAC systems are more complex, often using multiple units, zones, and advanced controls.
• Ductwork: Commercial ductwork is typically more extensive and complex than residential ductwork.
• Refrigerant: Commercial systems may use different types of refrigerant than those used in residential systems.
• Maintenance Requirements: Regular maintenance is essential for both types of systems, but commercial systems typically require more frequent and specialized maintenance.
• Cost: Commercial HVAC installation and maintenance costs are generally higher than residential due to system complexity and specialized labor required.

What is a rooftop unit (RTU)?

A rooftop unit (RTU) is a self-contained HVAC system commonly used in commercial buildings. It is typically installed on the roof and contains all the necessary components, such as the compressor, condenser, evaporator coil, and air handler, in a single unit. Regular maintenance is important for RTU systems due to exposure to weather conditions.

What is a packaged HVAC unit?

A packaged HVAC unit combines all the essential components of an HVAC system—heating, cooling, and sometimes ventilation—into one unit. It's typically placed outdoors, either on the ground or on a rooftop. They can be less expensive than split systems.

What is an Air Handling Unit (AHU)?

An Air Handling Unit (AHU) is a major component of many commercial HVAC systems. It's a large metal box that conditions and circulates air throughout the building. AHUs regulate air temperature, humidity, and quality in commercial spaces.
