AFUE

Annual Fuel Utilization Efficiency. AFUE is a rating that reflects how efficiently a gas furnace converts fuel to energy. An AFUE of 90 means that approximately 90 percent of the fuel is utilized to provide warmth to your home, while the remaining 10 percent escapes as exhaust.

 

Air Cleaner (also Air Filtration System)

A device that removes allergens pollutants and other undesirable particles from air that is heated or cooled.

 

Air Handler

The indoor component of your air conditioner or heating system that moves air throughout your home.

 

Allergen

All-In-One System (also Packaged System)

An air conditioning and/or heating system in which all components are located in one cabinet. Used in certain localities and for certain building types, the all-in-one system is installed either beside or on top of your home.

 

BTU

British Thermal Unit. In scientific terms, it represents the amount of energy required to raise one pound of water one degree Fahrenheit. One BTU is the equivalent of the heat given off by a single wooden kitchen match. For your home, it represents the measure of heat given off when fuel is burned for heating, or the measure of heat extracted from your home for cooling.

 

CFM

Cubic feet per minute, a standard of airflow measurement. A typical system produces 400 CFM per ton of air conditioning.

 

Capacity

The output or producing capability of a piece of cooling or heating equipment. Cooling and heating capacity are normally referred to in BTUs.

Home Automation (also smart home)

Anything that gives you remote or automatic control of things around your home including but not limited to your HVAC system, lighting or security system.

 

Hybrid comfort system

A home comfort system that combines a  heat pump with a gas furnace (also available in packaged systems). For areas with colder temperatures, combining electric heating (heat pump) with gas heating (furnace) lets you choose from two fuel sources in order to respond to fluctuations in utility costs.

 

Humidifier

A device that adds moisture to dry indoor air during wintertime and in hot, dry climates.

 

Humidity

The amount of moisture in the air. Variable speed systems can reduce this moisture for added comfort.

 

HSPF

Heating Seasonal Performance Factor. Refers to the efficiency of the heating mode of heat pumps over an entire heating season. The higher the number, the more efficient the unit.

 

HVAC

The classic acronym for Heating, Ventilation and Air Conditioning. Today, an HVAC system also includes air cleaning and moisture control.

 

Indoor Coil

The other, less visible half of your outdoor unit. It's attached to your furnace or air handler. As indoor air flows across it, heat and moisture are drawn out, leaving air that is cool, comfortable and conditioned.

 

Indoor/Outdoor System (also Split System)

Refers to a comfort system consisting of components in two locations. Common examples include an outside unit, such as an air conditioner, and an indoor unit, such as a furnace with a coil.

 

Load Calculation

A detailed analysis of your home's energy needs conducted by your dealer to help determine which comfort system is best for your home.

 

Matched System

A heating and cooling system where all of its components are matched in capacity and efficiency. This enables your system to perform at its best, and most efficient, for longer.

 

NATE

North American Technician Excellence. It's the nationwide certification program for home heating and cooling technicians. It's the only certification that is recognized by the entire industry.

 

Nexia™ Home Intelligence

Nexia Home Intelligence is a home automation system that, when paired with an American Standard AccuLink Platinum XV Control or AccuLink Remote Control, makes it possible to manage your home’s HVAC system, locks, lights, security and more by computer or most web-enabled cell phones.

 

Outdoor Unit

The outdoor portion of a split system such as an air conditioner or heat pump. May also be a packaged air conditioning and/or heating system in which all components are located in one cabinet.

 

Packaged System (also All-In-One System)

An air conditioning and/or heating system in which all components are located in one cabinet. Used in certain localities and for certain building types, the packaged system is installed either beside or on top of your home.

 

Refrigerant

A substance that produces a cooling effect. It's used in most air conditioning and cooling systems.

 

SEER

Seasonal Energy Efficiency Ratio, a rating that measures the cooling efficiency of a heat pump or air conditioner. The higher the number, the more efficient the unit.

 

SEET

Seasonal Extreme Environmental Test. It's the American Standard testing facility for heating and air conditioning systems, where the equivalent of five years of operation is condensed into 16 weeks of testing under harsh conditions. American Standard Heating & Air Conditioning wants to ensure your new system will be as reliable as possible.

 

Smart home (also home automation)

A smart home features an advanced system that offer remote or automatic control of the things around your home including but not limited to your HVAC system, lighting or security system.

 

Spine Fin™

A revolutionary technology that makes stronger, more efficient cooling coils. Spine Fin™ consists of thousands of tiny fins bonded to continuous aluminum refrigerant tubing. The tiny fins create a greater surface area, helping it to transfer more heat from your home, more efficiently. American Standard Heating & Air Conditioning features Spine Fin™ coils in many of our outdoor products.

 

Split System (also Indoor/Outdoor System)

Refers to a comfort system consisting of components in two locations. Common examples include an outside unit, such as an air conditioner, and an indoor unit, such as a furnace with a coil.

 

Thermostat (also control)

A temperature-control device, typically found on a wall inside the home. It consists of a series of sensors and relays that monitor and control the functions of a heating and cooling system. American Standard Heating & Air Conditioning's programmable thermostats allow you to program different levels of comfort for different times of the day.

 

Modulating Heating

Fully modulating heating provides greater fuel efficiency and ideal comfort control by constantly adjusting to changing temperatures in your home.

 

Ton

A unit of measurement used for determining cooling capacity. One ton is the equivalent of 12,000 BTUs per hour.

 

Two-stage Heating / Two-stage Cooling

Two-stage heating and cooling is considered to be more efficient, because it operates at a low, energy-saving speed most of the time. However, on days when more heating or cooling is required, it switches to the next stage for maximum comfort.

 

Variable-Speed Motor

The fan motor inside higher efficiency indoor and outdoor units is designed to change its speed based on your home's heating and air conditioning requirements. Working in conjunction with your thermostat, it keeps the appropriate-temperature air (e.g., warm air on cold days) circulating throughout your home, reducing temperature variances. The variable-speed motor also increases dehumidification and is quiet because it runs at a lower speed most of the time. Plus, the consistent air circulation eliminates noisy startups and shutdowns.
