Glossary of terms
-
- Air Handler
- An air handler, or air handling unit, is the indoor part of an air conditioner or heat pump that moves cooled or heated air throughout the ductwork of your home. It is usually a large metal box containing important elements of an HVAC system that controls airflow and filtration. Lennox® air handlers are among the most efficient and quietest you can buy.

- Central Air-Conditioning
- Central air conditioning (or central A/C) is a system in which air is cooled at a central location and distributed to and from rooms by one or more fans and ductwork. Lennox® central air conditioners are among the quietest and most energy-efficient units you can buy.

Understanding HVAC Coils and How They Work
Coils are the most important part of your HVAC (heating, ventilation and air conditioning) system. They make your home cool in the summer and warm in the winter. Understanding how your HVAC coils work and what to do to maintain them play a big role in saving you from a broken heat pump or air conditioner.

- Compressor
- An AC or heat pump compressor is the part of an outdoor air conditioner or heat pump that compresses and pumps refrigerant to meet household cooling requirements.
Learn More -
- Condenser
- A condenser (or AC condenser) is the outdoor portion of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year.

- Decibel (dB)
- A decibel (dB) is a unit used to measure the relative intensity of sound. For example, sound levels in a library are normally about 40 dB, normal conversations range from about 50 to 60 dB, and an operating motorcycle or garbage truck can be as high as 100 dB.

- Dry-Charged Unit
- An air conditioner or heat pump that is shipped dry and charged with refrigerant at the place of installation. Dry-charged units are appropriate for homeowners who need a replacement unit compatible with R-22 refrigerant.

- Energy Star®
- ENERGY STAR® is a program of the U.S. Environmental Protection Agency (EPA) designed to help consumers and businesses save money by choosing energy-efficient products and technologies. Heating, ventilation and air-conditioning (HVAC) equipment with the ENERGY STAR® label meets or exceeds federal guidelines for energy-efficient performance.

- Evaporator Coil
- The part of an air conditioner or heat pump that absorbs the heat from the air in your house. It is located inside the air handler or attached to the furnace.
Learn More -
- Fan Coil Unit
- A fan coil unit (FCU) is a device that uses a coil and a fan to heat or cool a room without connecting to ductwork. Indoor air moves over the coil, which heats or cools the air before pushing it back out into the room. FCUs can be less expensive to install than ducted systems, and are available in ceiling, floor-mounted and freestanding configurations.

- R-22 Refrigerant
- The old standard for residential air conditioners, now being phased out by the U.S. EPA. Lennox offers dry-charged units for those who still have R-22 compatible systems.

- R-410A Refrigerant
R-410A, is a chlorine-free, hydrofluorocarbon (HFC) refrigerant originally developed as a more environmentally friendly replacement for R-22. R-410A was developed and patented in 1991 by Honeywell.

- Refrigerant
Refrigerant is the working fluid used in air conditioners, refrigeration, and heat pump systems. It is a chemical compound that changes temperature as it transitions between liquid and gas form – cooling as it vaporizes, and heating up as it condenses. It is this property that facilitated a system’s ability to heat and cool.
-
- Refrigerant Lines
- Two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil.

- Scroll Compressor
- A specially designed compressor that works in a circular motion, as opposed to up-and-down piston action.

- SEER
Simply put, this rating measures how much energy a heating and cooling system uses to operate. Learn how you can use SEER and SEER2 ratings to increase efficiency – and savings – in your home.
Proper sizing and installation of equipment is critical to achieve optimal performance. Split system air conditioners and heat pumps (excluding ductless systems) must be matched with appropriate coil components to meet ENERGY STAR criteria.
