Texas is known for scorching summers, but winter can catch homeowners off guard. Sudden cold snaps, ice storms, and freezing temperatures can drive energy bills through the roof and even threaten the power grid. Whether you are a longtime Texan or new to the state, a little preparation goes a long way toward keeping your home warm and your energy costs manageable.
Why Texas Winters Are Unpredictable
Texas weather can swing from 70 degrees to below freezing in a matter of hours. Unlike northern states where homes are built for sustained cold, many Texas homes have lighter insulation and heating systems that were designed for occasional use. When a major cold front moves through, furnaces and heat pumps work overtime, and electricity demand across the state spikes dramatically.
Events like Winter Storm Uri in 2021 showed just how vulnerable the Texas grid can be during extreme cold. While grid improvements have been made since then, individual preparedness is still your best defense against high bills and uncomfortable temperatures.
Seal Air Leaks Before the Cold Arrives
One of the most cost-effective things you can do is seal air leaks around windows, doors, and any openings where pipes or wires enter your home. Weatherstripping and caulk are inexpensive and easy to apply. Even small gaps can let in a surprising amount of cold air, forcing your heating system to work harder than it needs to.
Pay special attention to attic access doors, garage-to-house doors, and older windows. If you can feel a draft when you hold your hand near the edges, it is time to seal them up.
Use Your Thermostat Strategically
Setting your thermostat to 68 degrees while you are home and lowering it a few degrees while you sleep or are away can make a noticeable difference in your bill. If you have a smart thermostat, set up a winter schedule that automatically adjusts temperatures throughout the day. Every degree you lower your thermostat can save roughly two to three percent on your heating costs.
Avoid the temptation to crank the heat up high when you first come home. Your system heats at the same rate regardless of the thermostat setting, so turning it to 80 will not warm your house any faster. It will just overshoot and waste energy.
Prepare for Power Outages
No matter how well you prepare your home, power outages are always a possibility during severe winter weather. Keep flashlights, extra batteries, and blankets easily accessible. If you have a fireplace, make sure it is clean and ready to use. Stock up on bottled water and non-perishable food that does not require cooking.
If you rely on electric medical equipment, have a backup plan in place before the storm hits. Know where your nearest warming center is located, and keep your phone charged so you can receive emergency alerts.
Lock In a Competitive Rate Before Winter
Energy prices in Texas tend to rise as demand increases during cold snaps. If you are on a variable-rate plan, your costs could spike significantly during a winter storm event. Locking in a fixed rate before the cold season begins gives you price predictability when you need it most.
