The Texas summer is coming. Here’s a straightforward, no-nonsense guide to what actually works — and what doesn’t.
There’s no shortage of advice out there about saving money on electricity. Some of it is genuinely useful. A surprising amount of it is either trivial or actively misleading. After eight weeks of going through how the Texas electricity market works, this column takes a turn toward the practical: what should a regular East Texas household or small business actually do to keep summer bills under control?
The honest version is that there are no magic tricks. Most of the savings come from a handful of straightforward steps that anyone can do, plus a few investments that pay back over a year or two. Here’s the rundown.
The Big Wins
Cooling is where the money goes. In the average East Texas home, air conditioning accounts for roughly half of the summer electric bill. Everything else — refrigerator, water heater, lights, appliances — is splitting the other half. That means almost every meaningful saving is going to come from how you manage your cooling.
Set the thermostat realistically. Every degree warmer you can tolerate saves real money. The standard recommendation is 78 degrees when you’re home and a few degrees warmer when you’re away or sleeping. A programmable or smart thermostat handles this automatically and is one of the fastest-paying upgrades you can make. A $150 thermostat that saves $20 a month pays for itself in less than a year.
Change your air filter monthly during the summer. A dirty filter forces your system to work harder, costs you money, and shortens the life of expensive equipment. Set a reminder on your phone for the first of every month from May through September.
Get an HVAC tune-up every spring. A trained technician can spot problems — low refrigerant, dirty coils, failing components — that quietly cost you 10 or 20 percent on your cooling bill. The hundred dollars or so spent on a tune-up almost always pays for itself within the first month.
The Quick Fixes
- Seal the obvious leaks. If you can feel air coming in around a door or window, you’re paying to cool the outdoors. Weatherstripping and caulk are inexpensive and easy. Don’t forget the gaps around plumbing under sinks and where wires come into the house.
- Use ceiling fans when you’re in the room. A ceiling fan doesn’t cool the air — it cools the people standing under it through evaporation. That means you can comfortably set the thermostat several degrees higher when fans are on. Just remember to turn them off when you leave the room.
- Close the blinds on the sun-facing windows. Direct sunlight through a window can add a remarkable amount of heat to a room. South-facing and west-facing windows are the worst offenders during the long summer afternoons. Cellular shades or thermal curtains make a noticeable difference.
- Run the dishwasher and dryer at night. Both produce heat, and running them in the evening reduces the load on your air conditioner during the hottest hours of the day. They also tend to be cheaper to run during off-peak hours if you’re on a time-of-use plan.
There are no magic tricks. Most of the savings on a Texas summer electric bill come from a handful of simple steps almost anyone can do. The mistake is doing none of them.
The Investments That Pay Back
Attic insulation. Most Texas homes built before the early 2000s are under-insulated by today’s standards. Adding insulation in the attic — bringing it up to current code — typically pays back in two to four years through lower cooling bills, and it makes the house more comfortable on extreme days.
Radiant barriers. A radiant barrier is a foil layer installed in the attic that reflects heat away from the living space below. In hot, sunny climates like East Texas, it can reduce attic temperatures by 20 or 30 degrees and cut cooling costs measurably. Often paired with insulation upgrades.
LED lighting. If you still have any incandescent or CFL bulbs in your house, replacing them with LEDs is one of the easiest upgrades available. The bulbs use a fraction of the electricity, last for years, and have come down dramatically in price.
Smart thermostats. Mentioned earlier, but worth repeating. The newer models learn your patterns and adjust automatically, and most can be controlled from your phone.
What About the Bigger Stuff?
Solar panels, whole-home generators, battery storage — all of these can make sense for the right household, but they require more careful analysis. The economics depend on your roof orientation, your usage patterns, your retail plan, available incentives, and a number of other factors. Anyone selling you on these systems with a quick pitch and a fast close is not your friend. A proper analysis from someone who doesn’t depend on the sale to make their living is worth the time.
For Small Business Owners
All of the above applies. A few additional items specifically for businesses:
- Look at your operating hours. If you have flexibility on when energy-intensive equipment runs, shifting it out of the 4-to-8 p.m. window can reduce both your demand charges and your contribution to grid stress.
- Consider a commercial energy audit. Most utilities offer them at low or no cost, and they can identify specific opportunities tailored to your operation.
- Review your contract terms with the seasons in mind. A contract that worked great when you signed it three years ago might not be the right structure for your current operation.
None of this is exotic. It’s the boring, fundamental stuff that adds up over time. The households and businesses that get serious about a few of these items consistently pay less than their neighbors. That’s not theory. That’s what the data shows, year after year.
