If your July and August statements make you wince, you are not alone. Homes across Killeen, Harker Heights, and Copperas Cove routinely see cooling account for more than half of a summer power bill. The good news: most of that cost is controllable. Here is how to lower your summer electric bill in Central Texas without sweating through the season.
Your air conditioner is the single largest energy consumer in a Central Texas home during summer. A system that is dirty, low on refrigerant, or running with a failing capacitor can burn 20 to 30 percent more electricity to deliver the same cooling. A few basics move the needle fast:
Every degree you raise the setpoint saves roughly 3 percent on cooling costs. Most Bell County families land comfortably at 76 to 78 degrees while home, with a modest setback of 4 to 6 degrees when the house is empty. Avoid deep setbacks: an air conditioner that has to pull a 90-degree house back down to 74 in August often works harder than the setback saved. A programmable or smart thermostat automates the swing so you never have to think about it.
Ceiling fans help, but only when someone is in the room. Fans cool skin, not air. Running them in empty rooms simply adds motor heat and a few dollars a month.
Central Texas attics can hit 140 degrees in August. If your ductwork leaks, and in older Killeen and Belton homes it very often does, you are paying to air condition that attic. Duct leakage of 20 to 30 percent is common in houses built before the mid-1990s. Warning signs include rooms that never quite cool, dust streaking around supply registers, and a system that runs nonstop well after sundown. Sealing duct connections and bringing attic insulation up to about R-38 are two of the highest-return improvements available in our climate.
An aging system that limps through summer on repeated repairs is usually the most expensive option on the table. If your unit is 12 to 15 years old, still uses R-22 refrigerant, or has needed multiple AC repairs in a single season, it is worth running the numbers on a high-efficiency replacement. Modern variable-speed equipment can cut cooling costs substantially, and Deane offers financing from $89/mo along with a 10-year parts and labor warranty through JB Warranties, so monthly savings can offset much of the payment. Proper sizing matters just as much as efficiency ratings, because oversized equipment short-cycles and wastes power, which is why our AC installation team performs a load calculation before quoting.
