Why Is My Electric Bill So High This Summer in OKC?
Most "why is my bill so high" advice is the same everywhere: change your filter, nudge up the thermostat. That advice isn't wrong, but in Oklahoma City it skips the single biggest factor most homeowners never think about. Here, your summer bill isn't only about how much power your AC uses. It's about when you use it. Under OG&E's summer pricing, the exact same kilowatt-hour can cost very different amounts depending on the time of day.
So the real answer has two halves stacked on top of each other: Oklahoma's punishing cooling season makes your air conditioner the biggest energy user in your home, and OG&E's peak pricing makes the power it burns from 2–7 p.m. on summer weekdays the most expensive of the day. Address both, the how much and the when, and the bill comes down.
In Oklahoma, your AC isn't just a big cost. It's most of the bill
Cooling is the single largest driver of a summer electric bill here, often around half of a home's total summer usage. That's a climate problem before it's an equipment problem: our cooling season stretches roughly five months, and during the 100°F-plus stretches your AC runs almost continuously just to hold its setpoint. A system that looks fine in April can quietly double your usage by July simply because it never gets a break.
That's also why the same house in Tulsa, Dallas, or Wichita sees a similar summer spike. It's the regional heat load, not necessarily anything broken. The opportunity is that a long, hard-running season is exactly where efficiency and timing improvements pay back the most.
The part most OKC homeowners miss: OG&E charges more from 2–7 p.m.
If you're on one of OG&E's SmartHours plans, and more than 120,000 area customers are, you get discounted, nearly half-price electricity for 19 hours a day on weekdays, plus all day on weekends and holidays, from June 1 through September 30. The trade-off is a higher price during peak hours: 2 to 7 p.m. on summer weekdays. Run your AC hard during that window and you're buying the most expensive power of the day; shift that same usage earlier or later and it costs a fraction as much.
There are a few flavors of the plan, and which one you're on changes your strategy:
- SmartHours Fixed: one set peak price for every weekday afternoon.
- SmartHours Daily: the peak price changes day to day (Low, Standard, High, or Critical), and OG&E notifies you a day ahead. On rare "Critical Event" days, prices are at their highest, usually for about two hours (4–6 p.m.) on a summer weekday, with at least two hours' notice.
- SmartHours Overnight: adds even cheaper "super-off-peak" power from 11 p.m. to 6 a.m., ideal if you can shift big loads to overnight.
OG&E's own advice is the move here: pre-cool your home before 2 p.m., then let the thermostat drift up a few degrees during the 2–7 p.m. window.
What's quietly inflating your bill ranked by how often it's the culprit
Beyond timing, a handful of issues make your AC work harder than it should. Roughly in the order we'd check them:
- 1A dirty air filter. The cheapest, most common offender. A clogged filter chokes airflow and forces longer run times. Replace it every 30–60 days in summer.
- 2Low refrigerant from a leak. A system that's undercharged runs much longer to reach temperature and never quite catches up on the hottest days.
- 3Leaky ducts baking in a hot attic. This is an Oklahoma-specific money pit, ductwork running through a 130°F+ attic loses cooled air into space you don't live in, and pulls superheated air back in.
- 4An oversized or aging system. Oversized units short-cycle (cool fast, shut off, leave humidity behind); aging ones simply use more power for the same result.
- 5A choked outdoor unit. Cottonwood, grass clippings, and dust on the condenser coil.
- 6Thermostat habits. Cooling an empty house all afternoon, or setting it very low, piles on cost, especially during peak hours.
How to actually lower it
You'll get the most relief by combining a timing change, a quick fix or two, and one service visit:
- 1Pre-cool, then coast through peak. Cool the house before 2 p.m. and set it a few degrees warmer from 2–7 p.m. on weekdays.
- 2Automate it with a smart thermostat. It handles the pre-cool/coast cycle for you. OG&E's Option to Connect program offers a bill credit for enrolling a qualifying smart thermostat, and rebates are listed at OGE.com/efficiency.
- 3Change the filter every 30–60 days through cooling season.
- 4Book a tune-up. A technician verifies refrigerant, cleans the coil, and restores airflow. The things you can't see that quietly run up the bill.
- 5Seal your ducts so you stop paying to cool the attic.
- 6Move big loads off-peak run laundry, the dishwasher, and the oven after 7 p.m. or on weekends.
When it's time to call a pro
If your bill jumped without any change in your habits, your AC runs nonstop, or the airflow feels weak, that's a system problem, not a usage problem, and it's worth a professional look before the worst of the heat. A maintenance visit catches refrigerant, coil, and airflow issues that no thermostat trick can fix. And if your AC has stopped cooling entirely during a heat wave, that's a same-day repair situation, not something to wait on.
Direct Air is a family-owned Oklahoma City HVAC company, and we'd rather help you get your current system running efficiently than sell you one you don't need. If your summer bills have crept up, a tune-up is the cheapest place to start. Book AC maintenance in Oklahoma City and we'll get your system back to pulling its weight.

Frequently asked questions
What are OG&E's peak hours in the summer? For SmartHours customers, peak hours are 2 to 7 p.m. on weekdays from June 1 through September 30. Electricity used in that window costs more than power used overnight, in the early morning, or on weekends and holidays.
Does pre-cooling my home before 2 p.m. actually save money?On a time-of-use plan like SmartHours, yes. Cooling your home before the 2–7 p.m. peak and easing back during it shifts your heaviest AC usage to cheaper hours, which is exactly the behavior the pricing is designed to reward.
Why is my electric bill high even though my AC is new?A new, efficient unit still can't overcome heavy peak-hour usage, leaky ductwork, poor insulation, or cooling an empty house all afternoon. The equipment matters, but timing and the home around it matter just as much.
Can an AC tune-up really lower my bill?Yes. Restoring airflow, cleaning the coil, and confirming proper refrigerant levels let the system reach temperature faster and run less, which shows up directly on your usage.
