A Heating, Ventilation and Air Conditioning (HVAC) Technician job ad on LinkedIn might read something like: “HVAC Technician needed for busy residential/commercial service company. Must have 3-5 years of experience and EPA certification. Company offers competitive salary and benefits package.”
Types of HVAC systems
The three most common types of HVAC systems are central air conditioners, furnaces, and heat pumps.
Central air conditioners are the most popular type of AC system. They use a system of ducts to distribute cool air throughout your home. Furnaces are the most common type of heating system. They use a system of ducts to distribute warm air throughout your home. Heat pumps are a type of HVAC system that can be used for both heating and cooling. They work by transferring heat from one place to another.
HVAC system components
The three main components of an HVAC system are the air handler, the furnace, and the air conditioner. The air handler is responsible for circulating air throughout the home. The furnace heats the air that is circulated by the air handler. The air conditioner cools the air that is circulated by the air handler.
Ductwork
Ductwork is a system of channels and pipes used to distribute heating, cooling, and ventilation (HVAC) throughout a building. The ductwork is typically made of sheet metal, fiberglass, or other materials that are easy to work with and can be formed into the desired shape. The ductwork is then connected to the HVAC equipment using insulation to minimize heat loss.
Thermostats
A thermostat is a device that controls the temperature of a space by turning heaters and cooling devices on or off as needed. The temperature is set using a knob or push-button interface. Thermostats typically have sensors that measure the temperature of the air in the space and use this information to turn the heaters and cooling devices on or off.
Thermostats are used in homes, offices, and other buildings to maintain a comfortable temperature. They can also be used in industrial settings to control the temperature of machinery or processes. Thermostats are an important part of HVAC (heating, ventilation, and air conditioning) systems and can save energy by turning off heaters and cooling devices when they are not needed.
Zoning
Zoning is the process of dividing land into sections for different uses. For example, a city may have a residential zone for houses and an industrial zone for factories. Zoning helps to keep neighborhoods safe and organized.
Energy efficiency
Energy efficiency is using less energy to provide the same level of service. For example, a more energy-efficient refrigerator uses less electricity than a less energy-efficient model.
Energy efficiency can be improved by using energy-saving devices and appliances, improving insulation, and sealing air leaks. These measures can save money on energy bills and help to protect the environment.
Indoor air quality
Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. IAQ can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mold, bacteria), or any mass or energy stressor that can induce adverse health conditions.
There are a variety of sources of indoor air pollution, including combustion sources such as oil, gas, kerosene, coal, wood, and tobacco products; building materials and furnishings as diverse as insulation, wallpaper, upholstery, and carpeting; glues, adhesives, and cleaning products; central heating and cooling systems and humidification devices; and outdoor sources such as radon and pesticides. In addition, there are a number of biological pollutants that can be found indoors, including mold, bacteria, viruses, and dust mites.
The most common symptoms of poor IAQ are headaches, nausea, dizziness, irritability, fatigue, and difficulty concentrating. More serious health effects can include respiratory diseases, heart disease, and cancer. Improving IAQ involves identifying and controlling sources of pollution, improving ventilation, and using air cleaners and purifiers.
Ventilation
Ventilation is the process of moving air in and out of a space. The purpose of ventilation is to remove contaminants from the air and to replenish the supply of fresh air. Ventilation can be achieved through natural or mechanical means. Natural ventilation relies on wind and temperature differences to move air, while mechanical ventilation uses fans and other mechanical devices to move air.
Refrigeration
Refrigeration is the transfer of heat from a colder object to a hotter object. By doing this, it makes the colder object colder and the hotter object hotter. The most common use for refrigeration is to keep food cold. When food is refrigerated, it slows down the growth of bacteria, which can cause food poisoning. Refrigeration also helps to keep food fresh for longer.
