Things You Should Know When Making Decisions about Residential Air Conditioning | A/C Education |

Have you ever worked with an air conditioning contractor and been confused by the jargon of the industry?  Have you ever listened to a company tell you that you need a certain product or service and wondered if you really needed it or if the technician is just trying to sell you something you don’t really need? | A/C Education |

At Baton Rouge Air Conditioning & Heating we recognize that the average person isn’t an expert about how to repair and air conditioning.  That’s why we are here.

We wanted to devote this page to educating the Baton Rouge public with some key terminology and ideas that will give the layperson a basic working knowledge of how air conditioning systems work and function.  Knowledge is power and having a basic knowledge of how something works will give you an advantage when making decisions about purchases.  Below, please submit any additional questions you have or any terminology you think we should define.

A/C Education

Air Conditioning System – Is a mechanical system whereby hot air is transferred from the inside of a home to outside the home.  This is done through a process where the system changes liquid refrigerant from liquid to gas and back to liquid a gain.  This process occurs repeatedly until enough heat is removed from the indoor air and the home achieves the desired temperature.

Compressor – this component circulates the refrigerant in an air conditioning system.  The compressor is the beating heart of an air conditioning system.  Its purpose is to pressurize the refrigerant so it leaves the compressor as a hot gas.  The compressor pushes the Freon through the air conditioning system and transfers the heat to the outside of the house.

Condenser – this part turns the hot refrigerant gas back into a cool liquid.  When the gas refrigerant turns back to a liquid it is much cooler than when it was in its gas form.  The heat is then transferred into the outside air by a fan that blows the heat away from the outside unit.

Evaporator – This component turns the liquid refrigerant back into gas.  When the refrigerant turns back to a gas it absorbs the heat from the air being pushed through the evaporator coil.  When the refrigerant vaporizes it absorbs the maximum amount of heat from the indoor air.  When the refrigerant leaves the evaporator, the heat is carried in the refrigerant as the refrigerant flows back to the outside part of the air conditioning system where the heat will be expelled.

Refrigerant – A liquid used to chill the indoor air through the process of evaporation and condensation.  Refrigerant is commonly known as Freon.  However, Freon is simply a name brand of refrigerant.

Thermostat – Regulates the air temperature by controlling when the air conditioner turns on and turns off.

Filter – The main purpose of the air conditioning filter is to keep you’re a/c system clean and to remove indoor air pollutants.  An air conditioning filter should be changed at least once every 3 months.  However, in Baton Rouge Louisiana during the summer when we are running our air conditioners constantly, the filters should be changed up to once a month.  Please refer to the

Dehumidifier – Air conditioning systems function as a dehumidifier since temperature has a direct relation to relative humidity.  Actually the first air conditioner was invented primarily as a dehumidifier.

Expansion Valve – Controls how much refrigerant flows into the evaporator

Air Duct – Are paths where air travels after it is heated or cooled by an air conditioning system.

Single Speed Air Conditioning System – A single speed system only runs at 1 speed: Full Blast.  A single speed unit always runs at 100% of its capacity.

Variable Speed Air Conditioning System – A Variable speed system adjusts its speed based on the cooling load needed at a specific time.  A variable speed system does not run a 100% of its capacity if it only needs to run at 80% of its capacity.  Therefore, a variable speed system can be a more efficient system.

Evaporator Coil – is the space through which refrigerant runs that draws the heat out of the air.

Cooling Capacity – Cooling capacity is typically measured in tons.  The capacity of an air conditioning system refers to how much heat it can remove from a home in 1 hour.

Drain Lines – Air conditioning drain lines drain the condensation that is accumulated by the air conditioning system.  The drain lines can become clogged and need to be cleaned periodically because they are usually gravity flow.
