Is the family thermostat stressing you out this time of year? Is it too hot for the heater but too cool for the A/C, and too inconsistent to pick one over the other day to day? If so, you may be suffering from Seasonal Thermostat Switching Syndrome, or STS Syndrome, a common condition that can affect you as the seasons change.

Ask yourself:

  1. Do you feel that your indoor temperature is either too warm or too cool in the span of the same day?
  2. Do you feel torn between leaving the A/C versus the heat on when you leave the house?
  3. When you’re at home, do you ever feel the urge to switch off the HVAC and leave the windows open to heat or cool your home?
  4. Have you recently disagreed with someone else in your home over whether it was too warm or too cool, or do you feel frustrated or unsure about it yourself?
  5. Have you recently changed from either cooling to heating and back or vice versa at home within the same day, or are others in your home urging you to do this?

If you answered "yes" to one or more of the previous questions, you may be suffering from Seasonal Thermostat Switching Syndrome, a condition that typically affects Texas electricity customers — and customers in similar climates — as the seasons change each year.

Tips For Neutralizing Seasonal Thermostat Syndrome:

Use an advanced programmable thermostat — some of these allow you to select a range of temperatures for your home, and they automatically switch between heating and cooling for you. And, some allow you to use your smartphone like a remote control for the thermostat — whether you’re at home or away.


If you don’t have access to an advanced thermostat, these tips may help:

  • Establish whether you can you stand being slightly warmer or cooler if you had to choose and select heating or cooling system based on this.
  • Know what indoor temperatures are most comfortable for you in summer and winter and compare this with the forecast. Choose heating or cooling based on which one is more likely to keep you closer to the indoor temperature you prefer.
  • Relax. You have options, whether you change your mind on your thermostat settings or look into a more automated alternative this time of year.
