Air Conditioning Terminology:
Airflow:
The distribution or movement of air.
Air Handler:
The indoor part of an air conditioner that moves cooled or heated air throughout
the ductwork of your home. An air handler is usually a furnace or a blower coil.
BTU:
A British thermal unit is a unit of heat energy. One Btu is the amount of heat
required to raise one pound of water by one degree Fahrenheit. The higher the
BTU rating, the greater the heating capacity of the system.
Central Air Conditioning System:
System in which air is treated at a central location and distributed to and from
rooms by one or more fans and a series of ducts.
Compressor:
The part of the outdoor air conditioner or heat pump that compresses and pumps
refrigerant to meet household cooling requirements.
Condenser Coil:
The outdoor portion of an air conditioner or heat pump that either releases or
collects heat, depending on the time of the year.
Ductwork:
The method by which air is channeled from the furnace or the blower coil
throughout your home.
Electronic Air Cleaner:
An electronic device that filters out large particles and bioaerosols in indoor
enviroments.
ENERGY
STAR®
A label attached to HVAC systems that meet or exceed the EPA guidelines for
energy efficiency.
Evaporator Coil:
The part of the air conditioner that is located inside the air handler. Its
primary function is to absorb the heat and humidity from the air in your house.
Horizontal Flow:
A type of furnace, installed on its side, which draws in air from one side,
heats it and sends the warm air out the other side. Ideal for attic and crawl
space installations.
Humidistat:
An automatic device used to maintain humidity at a fixed or adjustable set
point.
HVAC:
Heating, Ventilation and Air Conditioning.
MERV Rating:
The MERV (Minimum Efficiency Reporting Value) rating of a filter describes the
size of the holes in the filter that allow air to pass through. The higher the
MERV rating, the smaller the holes in the filter, the higher the efficiency.
Programmable Thermostat:
A thermostat with the ability to record different temperature/time settings for
your heating and/or cooling equipment.
R410A Refrigerant:
A chlorine-free refrigerant that meets the EPA’s newest, most stringent
environmental guidelines.
Refrigerant:
A chemical that produces a cooling effect while expanding or vaporizing. Most
residential air conditioning units contain the standard R-22 refrigerant, or
R-410.
Refrigerant Lines:
Two copper lines that connect the outdoor air conditioner or heat pump to the
indoor evaporator coil.
SEER
The Seasonal Energy Efficiency Ratio is an energy efficiency rating for air
conditioners. The higher the SEER, the better the energy performance, the more
you save. The established minimum SEER rating for cooling is 13.00. This minimum
rating has changed to 13.00 in January 2006.
Single Package:
A heating and cooling system contained in one outdoor unit.
Split System:
A combination air conditioner with indoor components, such as a furnace or
blower coil. Split systems should be matched for optimal efficiency.
Thermostat:
Usually found on an inside wall, this device operates as a control to regulate
your heating and cooling equipment, allowing you to adjust your home comfort at
the touch of a switch.
Ton:
Unit of measurement for determining cooling capacity. One ton equals 12,000 Btuh.
Upflow:
A type of furnace that draws cool air from the bottom and blows the warm air out
the top into the ductwork. Designed for basement or closet installations.
Variable Speed Motor:
Automatically adjusts the control of airflow for ultimate comfort.
Zoning:
A method of partitioning a home into independently controlled comfort zones for
enhanced comfort and efficiency.

WHAT IS A SEER?
Terms like SEER, AFUE and HSPF are commonly used to describe efficiency ratings
in the indoor weather industry. Offering indoor weather equipment that ranges
from the minimum industry requirements to the world's most totally energy
efficient, your indoor weather expert can help you choose the indoor weather
equipment that's right for you.
SEER- (Seasonal Energy Efficiency Ratio) is the measure of efficiency by which
the cooling process of air conditioners and heat pumps is rated. The higher the
SEER number, the greater the efficiency, which translates into greater energy
savings. U.S. NOTE: Starting Jan 2006 THE U.S. WILL REQUIRE ALL NEW MODELS
PRODUCED TO HAVE A 13.00 SEER RATING OR BETTER.
This is a breakdown of the savings
you can except by installing a higher efficiency air conditioning system.
