Frequently Asked Questions about Commercial HVAC

Find answers to common questions about commercial HVAC systems, services, and finding the right contractor for your business in USA.

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. RTUs are convenient and space-saving, but they can be more exposed to the elements and may require specialized maintenance.

What is a chiller, and how does it work?

A chiller is a refrigeration system that cools water or other fluids to a low temperature. This coolant is then circulated through pipes to air handling units or fan coil units, which cool the air in the building. They are typically more energy-efficient for large cooling applications compared to standard air-cooled AC units.

What is retro-commissioning (RCx)?

Retro-commissioning (RCx) is a systematic process for identifying, analyzing, and correcting operational deficiencies in existing buildings. RCx aims to improve energy efficiency and reduce operating costs without replacing major equipment. It can be a beneficial strategy for improving sustainability and reducing a company's carbon footprint.

What is commissioning (Cx) for commercial HVAC?

Commissioning (Cx) is a quality assurance process for commercial construction and renovation projects. It is performed during the design, construction, and post-construction phases to ensure system performance, energy efficiency, and compliance with project specifications.
