Air balancing is the process of testing, adjusting, and optimizing an HVAC system to ensure that the air distribution throughout a building or space matches the desired levels of comfort, efficiency, and performance. This involves measuring airflow from individual vents or diffusers, ensuring proper pressure in different zones, and making adjustments to dampers, ducts, or...

Air Changes Per Hour, often abbreviated as ACH or ac/hr, refers to the number of times the total volume of air in a specific space (like a room or building) is replaced with fresh air in one hour. This metric takes into account both mechanical ventilation (like HVAC systems) and natural ventilation (like windows or...

An air cleaner is a device used in HVAC systems to improve indoor air quality by removing particles and contaminants from the air. While the provided definition ("Removes airborne allergens from your home.") is partially correct, it is overly simplistic. Air cleaners do not only target allergens but also capture and reduce other airborne particles...

An appliance within an HVAC system designed to regulate indoor air temperature, humidity, and quality. Specifically, an air conditioner works to cool your home by removing heat from the indoor air and transferring it outdoors. This is achieved through a refrigeration cycle that involves a refrigerant circulating between the evaporator coil (indoor unit) and the...

An air filtration system is a component or set of components in an HVAC system designed to improve indoor air quality by removing airborne particles like dust, pollen, pet dander, mold spores, and other allergens. These systems work by using filters, which can range from basic fiberglass filters to high-efficiency particulate air (HEPA) filters. Some...

The total amount of air that moves through an HVAC system, usually measured in cubic feet per minute (CFM). Proper air flow ensures the efficiency and comfort of your HVAC system by maintaining the right balance between your indoor unit (like the furnace or air handler), outdoor unit (like the air conditioner or heat pump),...

Also known as air handling unit, is a key component of an HVAC system that helps circulate and manage airflow within a building or home. It typically consists of a blower (fan), heating or cooling elements (like a coil), filters to clean the air, and sometimes additional components like humidifiers or UV lamps for air...

An airside economizer is a system used in HVAC to improve energy efficiency by leveraging cool outdoor air for indoor cooling instead of relying solely on mechanical air conditioning. When the outside air conditions (temperature and humidity) are favorable, typically during cooler weather, the economizer brings in fresh outdoor air and reduces or bypasses the...

Ambient temperature refers to the temperature of the surrounding air or environment in which a system, equipment, or object is located. In HVAC contexts, ambient temperature is typically the air temperature surrounding an HVAC system or its components, such as an outdoor condenser unit. Understanding ambient temperature is critical because it can affect the performance...

The Air-Conditioning and Refrigeration Institute (ARI) was a trade association that developed standards for heating, ventilation, air conditioning, and refrigeration (HVACR) equipment in North America. Its primary responsibilities included creating performance guidelines, certifying products to ensure they met these standards, and promoting industry advancements. In 2009, ARI merged with the Gas Appliance Manufacturers Association (GAMA)...
