Ideal Thermostat Setting for Fall in Texas

If you’re just looking for a hard number to set your thermostat to for fall in Texas, we can jump straight to it. Fall in Texas can get quite hot during the day and quite cold in the evening, though, so a one-size-fits-all number isn’t going to be a good option. It’s best to set an upper limit before your air conditioning kicks in and a lower limit before your furnace gets to work.

The experts at Total Air & Heat recommend:

  • 68 degrees for heat
  • 78 degrees for the air conditioner

Thermostat Settings vs. Energy Costs in Texas

Deviating the temperature of your home or business a single additional degree from what it wants to be naturally costs a certain amount of power. Each degree of deviance costs more money each month. The Department of Energy, for example, estimates savings of 3% per month per degree you reduce your heat in cold months. Other estimates go higher, to 5% or more.

Healthy Temperatures

Our numbers above come from a combination of Department of Energy recommendations and health research. Temperatures between 68 and 78 degrees may not feel comfortable for everyone, but they should be healthy for anyone. It’s a good idea to try these temperatures and see if you can adjust to them before you begin adjusting up or down for heat or AC, if you’re aiming to save as much money as possible.

Of course, comfort plays its own role in health. If you’re cold all the time or hot all the time, you’re going to be stressed, which is unhealthy in and of itself. Don’t suffer excessively to save a few dollars!


Even if you’re comfortable bundling up for cold times or sweating it out when the temperature pops up a few degrees, you’ll want to keep in mind factors independent of temperature in your property such as air quality, and most notably moisture.

A moist home feels hotter when it is hot because your body can’t properly evaporate sweat to cool off when the air is saturated. A more moist home feels colder when it is cold, because the moisture in the air can pull heat from your body in the same way a swimming pool might. Moisture also contributes to mold growth and a host of other threats to health and property.

While You’re Out

It’s worth noting that you can save a huge amount of money by readjusting your thermostat when you’re going to be out, or setting your programmable thermostat to do it. If you don’t have pets, consider setting your thermostat to 85 degrees or so while you’re out on a hot day.

You can’t go as extreme for cold days, as Texas is quite humid and you’ll work your system hard to clear out the moisture when you get home — 60 degrees is a good compromise for heating, though you could go as low as 55 or so degrees safely for extended absences such as a fall vacation, depending on how efficiently your system deals with humidity.
