The HVAC (heating, ventilation, and air conditioning) industry is focused on the design, installation, and maintenance of systems that control the temperature, humidity, and air quality in buildings and other enclosed spaces. HVAC professionals work with a wide range of equipment, including furnaces, boilers, heat pumps, air conditioners, and ventilation systems, to ensure that buildings are comfortable and safe for occupants. HVAC services are often in high demand, especially in regions with extreme climates, and the industry plays a vital role in the construction and maintenance of commercial, residential, and industrial buildings.
