Did You Know?

Air-conditioning/refrigeration was selected as one of the ten greatest mechanical engineering achievements of the twentieth century, according to a survey of members of the American Society of Mechanical Engineers.

• Troubleshoot and repair existing HVACR systems by using digital tools and visual inspection methods • Perform preventive maintenance on customers’ HVACR systems including cleaning ducts; inspecting, adjusting, and replacing belts; lubricating motors, bearings, and pulleys and adjusting as necessary; checking refrigerant (a type of chemical that is used in air-conditioners and refrigeration systems to cool air) levels; replacing filters; and adjusting humidifier settings • Follow government rules regarding the conservation, recovery, and recycling or disposal of refrigerants • Respond to emergency calls such as malfunctioning furnaces and air-conditioners, carbon monoxide leaks, etc. Green construction, or green building, is a relatively new concept that stresses energy and water efficiency, indoor environmental quality, the use of eco-friendly or fewer construction materials (when possible), and the structure’s overall effects on its site or the larger community. Green heating and cooling technicians perform job duties such as: • Conducting energy audits of homes and businesses to help reduce the amount of energy being used and identify areas of the home or business where hot or cold air is being lost • Installing and servicing energy-saving furnaces and air-conditioners (including those that are full- or partly powered by solar energy , geothermal power , or other sources of green energy), programmable thermostats, and other energy-efficient equipment and devices. You’ll like working as a green heating and cooling technician if you care about protecting the environment and helping customers reduce energy waste, enjoy solving problems, and welcome interaction with others.
