Juan Torres A career in HVAC requires years of training and certification. This field requires technicians to be able to work with people in confined spaces, lift heavy equipment, and manage installations and repairs. HVAC technicians also need to be able to work under varying weather conditions, handle high-rise construction, and maintain safety standards. They must also be knowledgeable about the nuances of HVAC systems.
HVAC systems move air in many ways, but the most common method is through a system of ducts. However, modern systems do not require extensive renovations or the installation of large-scale duct systems. Some models can be installed with inconspicuous vents or insulated mini-ducts. And some do not even need ducts at all.
HVAC systems may also include ventilation systems, humidifiers, dehumidifiers, and air purifiers. These components are controlled by a thermostat, which can be conventional or smart. The latter allows for the homeowner to receive alerts whenever a set point is reached. Smart thermostats may even share diagnostic information with an HVAC contractor.
Air quality is a critical concern, so HVAC systems must be designed to address these issues. Many schools in the United States strive to reduce outdoor air pollution. For example, the American Society of Heating, Refrigerating, and Air-conditioning Engineers has set a minimum amount of outdoor air ventilation for classrooms. These minimums are easy to meet through basic engineering principles.
