Why Your Summer Electric Bill Is So High — and What Actually Helps

A high summer bill in Leander usually isn't one big problem — it's several small ones stacking up during a five-month cooling season. The encouraging part: the fixes with the best payback are often the cheapest. Here's how to spend your money in the right order.

Why summer is so expensive here

Air conditioning is the single largest summer load in most Central Texas homes, and our season is long and hot. That means anything making your AC work harder than it should — restricted airflow, lost cool air, an aging system — gets multiplied across months of runtime. Fix the multiplier and the savings compound.

The fixes, ranked by payback

Start here (free or nearly free):

• Replace the air filter monthly in summer. A clogged filter chokes airflow and is the #1 cheap cause we find.
• Set a smart thermostat schedule. Letting the house drift a few degrees while you're out saves real money over a season.
• Block the sun. Close blinds on west- and south-facing windows during peak afternoon heat.
• Clear vents and the outdoor unit. Don't block supply registers; keep two feet of clearance around the condenser.

Then invest where it counts:

• Seal leaky ducts. Duct leakage commonly wastes 20–30% of your cooled air into the attic — one of the highest-payback fixes in our climate.
• Get a professional tune-up. Dirty coils, low refrigerant, and a weak capacitor quietly raise runtime and bills. See our maintenance plans.
• Add attic insulation. Many Central Texas attics are under-insulated; topping up reduces heat gain all summer.

Bigger picture:

• Right-size and modernize. An aging or oversized system runs inefficiently. If yours is 12–15+ years old and bills keep climbing, weigh repair vs. replace and review SEER2 efficiency.

When high bills mean something's wrong

A sudden jump without a heat wave or rate change often points to a real fault — low refrigerant from a leak, a failing component, or a system struggling to keep up. If your home also isn't cooling well, start with Why Your AC Isn't Cooling.
