Tex’s Guide to Thermostat Settings That Actually Save Money

Howdy, neighbors. It is Tex here from Wrangler Air Conditioning. We have been a family-owned outfit here in San Antonio since 2014, and if there is one thing we know, it is that Texas heat does not play fair. Right now, we are looking at temperatures hitting 90 degrees this Tuesday. That is a bit early for that kind of heat, even for us. With the way the weather is moving, we are all starting to feel that itch to reach for the thermostat and crank it down as low as it will go. Before you do that, I want to share some straightforward advice that will keep your home cool and your wallet full.

We are currently facing some real challenges in our neck of the woods. San Antonio is in its seventh month of extreme drought. We have only seen about 0.44 inches of rain this March, which is way below what we usually get. On top of that, CPS Energy is looking at a 4 percent rate increase, and SAWS is proposing an 8 percent hike. When you add up the heat, the dry air, and the rising costs, it is more important than ever to be smart about how you run your cooling system. I am not here to sell you something you do not need. I am here to give you the same advice I would give my own brother over a cup of coffee.

Best Thermostat Settings San Antonio Homeowners Should Use

The question I get asked most often is what the magic number is for the thermostat. If you want to save the most money while staying comfortable, the Department of Energy suggests setting your thermostat to 78 degrees when you are at home. I know that might sound a little warm to some of you, but in our San Antonio climate, it is the sweet spot. When you are away from the house for more than a few hours, you should let that number climb up to about 82 or 85 degrees. This keeps your AC from working overtime to cool an empty house.

The reason this works is simple physics. The smaller the difference between the temperature outside and the temperature inside, the lower your overall cooling bill will be. When it is 90 degrees outside like it is expected to be tomorrow, your AC has to work a lot harder to keep the house at 68 than it does to keep it at 78. By keeping that gap smaller, you are taking a huge load off your equipment. This is not just about saving a few bucks today. It is about making sure your system stays dependable for years to come. A system that runs constantly is a system that breaks down sooner.

How to Thermostat Save Money During San Antonio Heat Waves

One of the biggest mistakes I see folks make is what I call the refrigerator method. They come home to a warm house and set the thermostat to 60 degrees, thinking it will cool the house down faster. I am going to be honest with you: it does not work that way. Your air conditioner is like a light switch, not a gas pedal. It is either on or it is off. It blows the same cold air whether you set it to 60 or 70. Setting it lower just means it will run longer and likely overshoot your comfort zone, wasting energy and money along the way.

With the projected average residential electric cost hitting 13.6 cents per kWh this March, those extra hours of running your AC really add up. Instead of cranking it down, try using ceiling fans. A good fan allows you to raise the thermostat setting by about 4 degrees without losing any comfort. Just remember that fans cool people, not rooms. If you leave the room, turn the fan off, or you are just wasting electricity. It is these small, dependable habits that make a real difference in your monthly budget.

Dealing with San Antonio Humidity and Extreme Drought

We are currently seeing humidity around 53 percent. While that is not as high as it gets in July, combined with the extreme drought, it creates a unique challenge for your HVAC system. When the air is dry and dusty like it is now, your outdoor coils can get dirty much faster. A dirty coil is like trying to breathe through a thick blanket. It forces your system to work harder and run longer to achieve the same cooling effect. This is why regular maintenance is so important for every San Antonio family.

Another thing to watch is your thermostat fan setting. Make sure it is set to Auto rather than On. When the fan is set to On, it runs all the time, even when the cooling cycle is finished. This can actually pull the moisture that was just removed from your air back into the house before it has a chance to drain away. In a humid place like San Antonio, keeping that fan on Auto ensures that your home stays dry and comfortable, which makes 78 degrees feel a lot cooler than it actually is.

Incentives and Credits for San Antonio Residents

Since we are talking about saving money, I have to mention the programs available right here in town. CPS Energy has a program called WiFi Thermostat Rewards. If you have a smart thermostat and you sign up, they offer a one-time 150 dollar bill credit. They also have the Power Player program which helps manage demand on the grid during those blistering summer afternoons. It is a fair deal for anyone looking to offset those upcoming rate increases. If you do not have a smart thermostat yet, now might be the time to look into one. They take the guesswork out of scheduling and can be controlled from your phone while you are at work or at the grocery store.

For those of you looking at the bigger picture, there is also a 30 percent federal tax credit available for high-efficiency heat pump installations in 2026. If your old AC unit is struggling to keep up with these 90-degree days and you are tired of the repair bills, a heat pump is a reliable and energy-efficient option. It handles both cooling and heating, and it is perfect for our San Antonio weather where we do not get too many hard freezes. It is a smart way to invest in your home comfort while taking a big bite out of your energy usage.

Preparing for the Easter Sunday Cold Front

Now, don't get too settled into the heat just yet. The forecast says we have some strong thunderstorms coming late Wednesday night, and a significant cold front is moving in by Saturday. Easter Sunday is expected to have highs only in the mid-60s with breezy conditions. This is the classic San Antonio weather roller coaster. When these fronts come through, it is a great time to give your AC a rest. Open the windows if the air is clear, but keep an eye on the dust if the drought continues.

When the temperature drops like that, you might be tempted to switch over to heat. If you do, just be aware that you might smell a little dust burning off the heat strips if you have an electric furnace. That is normal for the first few minutes. However, with a high of 60, you might find that your home stays plenty warm just by keeping the windows shut and letting the Texas sun do the work. Being mindful of these temperature swings is a straightforward way to keep your bills from spiking during the transition between seasons.

The Importance of Maintenance for Efficiency

I can talk about thermostat settings all day, but if your system is not running right, those numbers on the wall do not mean much. A system that is low on refrigerant or has a clogged filter will run and run without ever reaching your target temperature. That is why we always tell our neighbors that a little bit of maintenance goes a long way. Checking your filters once a month is the easiest thing you can do to keep your system honest. If you can't remember the last time you changed it, it is probably time.

At Wrangler Air Conditioning, we believe in being thorough. During a maintenance visit, we check the electrical connections, clean the coils, and make sure the drain lines are clear. With the drought and the lack of rain, we are seeing more dust and debris than usual getting trapped in those outdoor units. Keeping those components clean is the most dependable way to ensure your AC survives the long summer ahead. We have been serving this community since 2014, and we have seen plenty of systems fail simply because they were neglected during the spring.

Final Thoughts from the Comfort Cowboy

Saving money on your cooling bill in San Antonio does not require any fancy tricks or expensive gadgets. It comes down to being consistent and making smart choices. Set your thermostat to 78, use your fans, and take advantage of the credits CPS Energy is offering. Keep an eye on the weather and adjust your settings when those cold fronts roll through. Most importantly, treat your HVAC system with respect, and it will return the favor by keeping your family cool when the Texas sun is at its worst.

We are proud to be a local, family-owned business. We live in the same neighborhoods you do, and we deal with the same electric bills. If you ever have questions about your thermostat or you feel like your system is not performing the way it should, give us a holler. We will give you a real, honest assessment without any sales pressure. That is the Wrangler way. Stay cool out there, San Antonio, and have a blessed Easter weekend.
