It’s the end of the year, and we’re experiencing bone-chilling temperatures here of around … let’s see … 67°F during the day. Yes, not exactly the Blizzard of 1888 (fun facts on that, if you’re interested) and not quite the temperatures that will make you depend on your home heating system.
But the mild temperatures of winter do pose a challenge to us because finding the ideal setting on the thermostat can be tricky. Sometimes days will warm up just enough that you’ll need the AC running, and then the next day drop down just cool enough to have the heater come on. If you’re moving the thermostat setting up and down all the time, that’s probably creating energy waste without giving you the comfort results you want.
No Matter the Temperature, Remember these Two Facts…
These two facts will help you understand the “why” of how the thermostat is set.
- Heat loss or heat gain slows down the closer indoor and outdoor temperatures are to each other. This is why extreme temperature settings on a thermostat are so wasteful. Cranking the heat up too far means heat leaves the house faster. Blasting the air conditioning causes heat to move into the house faster. Aim to find a temperature inside that’s comfortable but also as close as possible to the outside temperature.
- The thermostat is a switch, not a throttle. You won’t get more heating or cooling delivered faster with extreme high or low settings. You’re only telling the heater or AC to stay on for longer. Steady settings are better for energy efficiency and comfort.
Now let’s look at the recommended thermostat settings.
When You Have the Heater On
Set the thermostat at 68°F during the day when people are home. This is a comfortable enough temperature for most people. Most of the time, the heater won’t even need to turn on or stay running for long. Lower the temperatures further at night or when the house is empty, usually around 60°F.
When You Have the AC On
The best daytime setting for staying cool is 78°F, and with proper ventilation, open windows, and fans you may not even need to have the AC running until the temperature has risen into the 80s. At night time or when the house is empty, raise the temperature by 8°F to 86°F.
A Smart Thermostat Is a Great Help
The best way to avoid having to change the programming regularly on the thermostat to adjust to days that are hot or cold is to have a special “smart” thermostat installed. This thermostat learns from your patterns of climate setting and from the house conditions to create its own programs that maximize energy use. In our area, this kind of thermostat is especially beneficial, since it adapts to our mild climate and can change between heating and cooling easily.

High on our list of ways to help lower the cost of staying cool in a Texas summer is ceiling fans. A ceiling fan doesn’t lower a room’s temperature, but it does make it easier for people in the room to stay cool. It’s the power of “wind chill”: when a breeze moves over your body, it takes away the heat envelope around you from heat escaping through your skin. When this envelope is removed, it allows for more heat to leave your body so you feel cooler than the air around you.
You won’t need 
When the winter temperatures start to drop into the 40s during the evenings in Texas, you’ll be glad you have a powerful furnace to warm your family. The reassurance of a furnace that you can depend on makes it easy to glide through the winter season, and our team is glad to help you with the finest available 
Air conditioning is the top 
In other parts of the country, winter is a time when air conditioning systems shut down for months until needed again in the spring. We don’t have that kind of climate in Texas! We have plenty of colder days, but the heat can always make a return, and air conditioners need to be ready to work at any time.
We all have in our heads an ideal version of what “October” looks like. It’s filled with autumn colors and crisp leaves and pumpkins and a slight chill to the dry air. People have this idealized October in their minds wherever they live, even if the world outside their windows never looks like it. And here in Texas, we don’t necessarily get a cool, crisp October. In fact, plenty of October days can feel close to summer days, with regular temperatures in the 80s.
Last year we wrote a post about what to do about your air conditioning system 
You probably know what Texas weather is like—summer temperatures hang around for a long time, even after the official first day of fall. We started the month of September with temperatures in the high 90s. That’s serious air conditioner weather. An air conditioner can lower the temperature inside a house by a maximum of 20°F. So when you have a 96°F day, you almost have to work the AC to the maximum to get the house down to the recommended 78°F for comfort. (Try not to set the thermostat lower than this, especially in intense heat, since it not only wastes energy, it can actually lead to the evaporator coil icing over.)
