A heating, ventilation, and air conditioning (HVAC) engineer designs, installs, and maintains heating, ventilation, and air conditioning engineering systems in buildings. These can include HVAC systems in offices, stores, factories, transportation facilities such as airports and train stations, schools, hospitals, and homes.

 

HVAC engineers design HVAC systems that meet the specific requirements of the building type. This includes calculating heat load and airflow requirements, selecting appropriate equipment and components, and designing ductwork and piping systems. They must select appropriate equipment such as boilers, chillers, air handlers, and other components for those particular HVAC systems. They do this by evaluating equipment specifications, performance, and efficiency, and making recommendations based on the needs and budget available.

 

HVAC engineers also oversee the installation of HVAC systems to ensure that they are installed according to design specifications, code requirements, and industry standards. They work with contractors, technicians, and other professionals to ensure that the installation is done correctly. After installation, HVAC engineers perform testing and commissioning to ensure that the system is operating correctly and efficiently. They perform functional tests, airflow tests, and other measurements to verify that the system is performing according to design specifications.

 

HVAC engineers are furthermore responsible for maintaining and troubleshooting HVAC systems. They perform regular maintenance to ensure that the system is operating efficiently and identify and troubleshoot issues that arise, such as equipment failures, refrigerant leaks, or airflow problems.

 

In designing and maintaining HVAC systems that are energy-efficient and cost-effective, they must be aware of energy-saving measures too. Such measures include upgrading equipment, optimizing system controls, or implementing renewable energy systems.

 

With the continued growth in building worldwide, HVAC engineers are always in demand. They are typically employed by engineering, construction and real estate companies, or other service-providing companies who offer HVAC solutions.
