What are Some Common HVAC Terms That You Should Know?
There are many HVAC terms that you will learn about in an HVAC program at CyberTex. Here are a few common HVAC terms that you should know:
ABS (Acrylonitrile Butadiene Styrene): This is a type of plastic piping used for waste, drain, and vent applications. It’s appreciated for its strength, temperature resilience, and resistance to impact.
Aerator: A device typically attached to a faucet that mixes air with water. It helps reduce splashing, conserves water, and often improves water pressure.
Angle Stop: A shutoff valve, found under sinks or toilets, that controls the water flow to these fixtures. It’s angled 90 degrees, hence the name.
Air Gap: A safety feature designed to prevent backflow of dirty water into clean water supplies. It’s often seen in dishwashers and sinks.
Air Handler: the indoor part of an air conditioner or heat pump that moves air throughout the ventilation in a structure.
Adapter: A fitting that connects pipes of different sizes or materials together, ensuring a seamless flow within the system.
Anode Rod: A sacrificial rod made from magnesium or aluminum with a steel core, found in water heaters. It’s designed to corrode instead of the water heater tank itself.
Auger: Often known as a plumber’s snake, an auger is a flexible tool used to dislodge clogs in drains and pipes.
Atmospheric Vent: A type of exhaust system that uses air from the surrounding environment to assist in venting waste gases from appliances like water heaters.
Air Lock: A blockage in a pipe caused by an air bubble, often resulting in reduced or stopped water flow.
Air Admittance Valve: A one-way valve designed to allow air to enter a drainpipe for proper venting, while preventing sewer gases from escaping into a building.
Auxiliary Drain: Secondary drainage system typically seen in air conditioning units to prevent water overflow if the primary drain is blocked.
Adjustable Wrench: A commonly used tool in HVAC, whose jaw width can be adjusted to grip nuts and bolts of different sizes.
Anti-Scald: A feature often seen in faucets and shower valves that prevents water from reaching dangerously high temperatures.
Balancing Valve: A valve used in a heating or cooling system that accurately controls the amount of water flow to various parts of the system for optimal performance.
Barb: A section of pipe with a rough edge used to connect hoses in an HVAC system.
Boilers: a device that heats water and provide hot steam for heating. The steam is distributed by pipes to a steam radiator.
Bushing: A fitting used to connect pipes of different sizes.
Check Valve: A type of valve that allows fluids to flow in one direction but closes automatically to prevent flow in the opposite direction.
Chiller: a refrigeration system used to lower the temperature by removing heat from the system and transferring it outside.
Compressor: part of an air conditioner or heat pump that compresses and pumps refrigerants to cool the inside of a structure.
Condensate: The water produced when air is cooled by an air conditioner or heat pump.
Coupling: A short fitting used to join two pieces of pipe.
CPVC (Chlorinated Polyvinyl Chloride): A type of plastic pipe used in HVAC systems for the distribution of hot and cold water.
Cut-off Valve: A valve that completely stops the flow of water through a pipe.
Dampers: Devices used in ductwork that regulate air flow.
Decibel: A unit used to measure the intensity or loudness of sound.
Deliming: The process of removing lime scale buildup from a boiler, water heater, or any HVAC fixture.
Dielectric: A type of fitting designed to prevent corrosion caused by dissimilar metals touching.
Direct Vent: A method of venting exhaust gases from an appliance directly outside, without using a chimney.
Drain Valve: A valve at the bottom of a water heater that allows the tank to be drained for maintenance or replacement.
Drip Leg: A pipe installed at a low point in a gas piping system to collect and remove condensation or foreign material.
Dual Element Water Heater: A water heater with two heating elements that provides a quicker recovery time.
Expansion Tank: A tank designed to absorb excess pressure due to thermal expansion in a closed water heating system.
External Vent: A vent that leads outside to allow gases to escape safely from your home.
Fitting: A general term for any piece that joins together sections of pipe.
Flare Fittings: Fittings used to connect pipes made of different materials, often used in gas piping.
Galvanized Pipe: Steel pipe that is coated in zinc to resist corrosion.
Heat Exchanger: A device in a boiler or furnace that transfers heat to the surrounding air or water.
Heat Pump: A device that uses electricity to transfer heat from a cool area to a warm area.
ID (Inside Diameter): The measurement of the inside diameter of a pipe, which determines the volume of fluid the pipe can carry.
Impeller: A rotating part of a centrifugal pump or compressor that moves fluid by rotation.
Joint: The location where two sections of pipe or HVAC components are connected.
Jacket: The outer shell of a water heater or boiler that protects the insulation from physical damage.
Jumper: A short length of conductor or flat metal used to bypass a portion of an electrical circuit.
Kilopascal (kPa): A metric unit of pressure measurement.
Pressure Regulator: A valve that automatically cuts off the flow of a liquid or gas at a certain pressure.
Relief Valve: A safety valve that releases excess pressure.
Roof Vent: A pipe that allows gas to escape from your home’s plumbing system.
Sleeve: A pipe that is passed through a wall for the purpose of inserting another pipe through it.
Tankless Water Heater: A type of water heater that heats water directly without the use of a storage tank.
Threaded Fitting: A type of fitting that screws onto the threaded end of a pipe
Zone: In the context of HVAC systems, a zone is a space or group of spaces within a building with heating and cooling requirements that are sufficiently similar so that desired conditions can be maintained throughout using a single controlling device.
Zone Valve: A device, usually placed near the heater or cooler, which controls the flow of water or steam to parts of the building.
Zone System: A method of controlling the distribution of heating or cooling in a system by dividing a home into zones controlled by separate thermostats.
