A commercial HVAC unit is a type of heating, ventilation, and air conditioning system designed specifically for commercial buildings. It is typically larger and more powerful than residential HVACHVAC systems, and is designed to provide heating and cooling to larger areas. Commercial HVAC units are designed to be more efficient and reliable than residential systems, and are capable of providing consistent temperatures throughout a building. They are also designed to be more energy efficient, which can help reduce energy costs. Commercial HVAC units are often used in office buildings, warehouses, and other large commercial buildings. They are typically installed by a professional HVAC technician, and require regular maintenance and servicing to ensure they are running properly.
