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.

A Variable Refrigerant Flow (VRF) system is a type of HVAC system that provides highly efficient and customizable heating and cooling for commercial spaces. They offer precise temperature control and enhanced comfort. A qualified HVAC professional can help determine if a VRF system is right for your business.

An Air Handling Unit (AHU) is a key part of many commercial HVAC systems. It's a large metal box that contains a blower, heating and/or cooling elements, and filters. AHUs regulate air temperature, humidity, and quality in commercial spaces.

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. Chillers are often used in large commercial buildings, such as office towers and hospitals.

A Variable Air Volume (VAV) HVAC system adjusts the volume of air based on the heating and cooling needs of specific spaces. This provides greater temperature control and improves energy efficiency by only delivering the precise amount of air needed. A VAV system is often used in large commercial or office buildings.

A Building Automation System (BAS) is a computerized system that controls and monitors building mechanical and electrical systems, including HVAC, lighting, security, and fire safety. A BAS integrates various building systems and equipment, allowing building managers to control and optimize their operations from a central location. Using a BAS enhances building operations and allows for preventive maintenance and system optimization.

An Energy Management System (EMS) is a system designed to optimize energy use in a building. An EMS can monitor energy consumption data, identify areas of waste, and automatically adjust building systems to reduce energy use and costs. It can be a valuable tool for businesses seeking to reduce their environmental impact.

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. In short, it confirms that a building's systems and components meet the project's stated objectives and the owner's operational needs.

Retro-commissioning (RCx) is a cost-effective way to optimize the performance of an existing HVAC system. It involves evaluating the building’s HVAC systems and controls, identifying energy-saving opportunities, implementing corrective measures, and verifying improved performance. Retro-commissioning can significantly reduce energy waste, enhance comfort, and extend the life of existing HVAC systems.

Indoor air quality (IAQ) significantly affects employee health, comfort, and productivity. Poor IAQ may contribute to various health issues, such as allergies, asthma, headaches, and respiratory illnesses. By prioritizing IAQ, businesses can create a healthier and more productive work environment, reduce sick leave, and potentially attract and retain top talent. A well-maintained and properly designed HVAC system is essential for providing good IAQ.

These are some ways to enhance your IAQ:

• HVAC Maintenance: Ensure regular maintenance, including filter replacements, coil cleaning, and ductwork inspections.
• Ventilation: Increase ventilation rates to bring in fresh outdoor air.
• Air Purification: Install air purifiers with HEPA or other high-efficiency filters to remove airborne particles.
