The old saying "the bigger the better" isn’t always accurate, especially when you’re discussing the probability of an oversized heating and air conditioning system for your Atlanta, Georgia, home. Although Georgia experiences diverse weather throughout the four seasons, if your heating and air conditioning unit is too large, you aren’t getting the maximum effects it is designed to provide for energy efficiency. 

Increased Monthly Utility Bill

There are several indicators that your heating and air conditioning system is too large for your home. The first and most costly reason is an increase in your monthly utility bill. An oversized unit does not run through its cycles as it should, creating a stop/start or short cycle situation. Because the system is too large, it reaches the cooling or heating level too quickly versus reaching the correct room temperature setting on the thermostat.

Uneven Heating or Cooling

An oversized system running short cycles creates the problem of inconsistent heating or cooling in the rooms. A short cycle runs for a limited time — an average of eight to 10 minutes versus the normal cycle time of 15 to 20 minutes. This results in some rooms being warmer or colder than others. The frequent on and off process not only increases energy usage, it also puts unnecessary strain on the unit, which is continually attempting to adjust the temperature.

Higher Humidity Levels

You will most likely notice the humidity in your home has increased. When the heating and air conditioning system is running short cycles, the unit does not have enough time to dehumidify the home. This increase in the humidity level can easily lead to signs of discoloration on the walls and ceiling because of biological growth.
