No, 72 degrees Fahrenheit is generally not too cold for a residential air conditioner and is a very common temperature setting for maintaining indoor comfort during hot summer weather. However, if your home has poor insulation, leaky ductwork, or an oversized AC unit, setting the thermostat to 72 can cause the system to cycle on and off too rapidly, leading to high electricity bills and clammy indoor humidity. For optimal energy efficiency, many homeowners aim for 74 to 78 degrees. Verification: Check indoor humidity levels to ensure your AC runs long enough to dehumidify the air effectively at your chosen temperature.
