There is something to be said for understanding the lingo when it comes to central air conditioning systems. When you start to meet with professionals and also just do your research online, what you are going to find is that there is going to be a lot of terminologies you may not be too sure about. To fully understand everything that you are reading, you need to know the standard air conditioning terms out there.

Air Flow

One of the most common terms that you are going to hear when you start to talk about a central air conditioning system is that of airflow. The airflow is going to be a measure of just how much air the duct system that you have is going to be able to move.

The airflow is critical when you are talking about an HVAC in Jacksonville FL because it will focus on how much cold air will circulate. For every ton of air conditioning capacity, the expectation is that the system is going to be able to move around about 400 cubic feet per minute of air. When you get to a climate that is more humid, that number is going to lower a bit.

The System Charge

You are going to hear professionals refer to the system charge all of the time when talking about a central air conditioning system. Checking the charge is simply a term that relates to checking the refrigerant levels of the system. The refrigerant that is within your central air conditioning system’s unit is what is going to allow for the cold air to be created. The pressure of the refrigerant will be checked so that the pro will give you assurance the system will do what you wish.


The compressor is part of the air conditioning system that usually sits outside. It is a noisy unit that can condense the air. It increases the temperature and pressure of the refrigerant to get it circulating throughout the home.


Just what does HVAC Jacksonville FL stand for? The term HVAC does have a full name, and it is called the heating, ventilating, and air conditioning system. Those words make up the abbreviation that we refer to all of the time as HVAC. It is a general name that is going to cover the entire space.


One of the other prevalent terms that you are going to see as you begin to shop for a central air conditioning system is that of the SEER. The SEER is a rating that is assigned to a central air conditioning system. It is a measure of the energy efficiency of the system. To come up with the SEER number, the BTU/HR of cooling the system can generate is divided by how much electricity is needed to run it. The bare minimum SEER rating you will see is going to be 13. The higher you go, the better the energy efficiency of the system. The higher-rated systems usually will have an increased price tag though as well.
