Heat Pumps in Athens GA – What You Should Know About Efficiency Terms and Components

Published on: July 20, 2012

As the main form of heat redistribution in the average household, the heating element is an especially important part of the overall comfort and health of the people in your living space. In especially volatile weather conditions, like those that exist in Athens GA for example, it is especially important to keep the heat pumps in your various appliances in good working order.


Heat pumps serve as a type of air purifier, making sure that the indoor air quality of your living space remains as safe as it can be. If you ever experienced a dip in the indoor air quality of your living space, the problem could be traced to your heat pump system.


The extreme humidity and dramatic temperature changes in places like Athens, GA can negatively affect the health of the heat pumps in your home, meaning that the overall health of anyone in that living space will be negatively affected. Below are some of the things that you must know about the heat pumps in your house and how to take care of them.


Just because heat pumps are more simplistic in nature than other types of HVAC oriented redistribution systems does not mean that they are easier to take care of. Many people believe that because the components in a heat pump system are more simple than in an HVAC system, they do not need a properly licensed technician to perform services. This is quite a dangerous stance to take and not one that is espoused by the more stringent state regulatory bodies in places like Arizona, California, Florida and Arkansas.


Below are the most important components with the most direct effect on your indoor air quality as an air purifier system:

The coils – Coils act in opposition to each other in a heat pump, with one acting to absorb heat and the other to disseminate the heat that the first coil gathers.

The compressor – Perhaps the most important part of the heat pump, the compressor concentrates the energy and circulates the materials through the coils.

The expansion valve – This part of the heat pump depressurizes the refrigerant, which converts it to a gas.

The refrigerant – This is the bloodline of the heat pump. It must be kept as pure as possible.


Make sure that any service that you have done to your heat pump system is done by a fully licensed technician.

Too often, people do not realize the importance of the heat pump as an air purifier, which directly affects the indoor air quality of the living space. The efficiency of your heat pump system is directly related to the indoor air quality of your living space and the ability of your entire ventilation system’s ability to act as an air purifier. There are four different types of efficiency ratings on heat pumps which will be described below.

COP – This acronym stands for coefficient of performance. COP determines the efficiency of a system in both cooling and heating modes.

SEER – This is the seasonal energy efficiency ratio. This metric measures efficiency in a range of temperatures relative to the peak season (the hottest and coldest times of the year). If you have a heat pump with a SEER rating of 20, then you have one of the best heat pumps that money can buy.

EER – This stands for energy efficiency ratio. You want your EER to be as high as it can possibly be.

HSPF – This is an expression of heating efficiency which is based on a calculation of the number of British thermal units that a unit uses.


You want to measure your heat pump by all four of these standards, in order to maximize the value of each metric that your heat pump has. Check your state regulations for any minimums that correspond to the weather conditions in your particular geographic area. The higher the ranking that your heat pump has, the better of an air purifier it becomes.
