What Summer Power Costs Look Like in Mckinney
Residents of Mckinney, TX can expect their summer energy bills to rise significantly compared to the milder spring and fall months. The average monthly electric bill from June through August hovers around $180, a steep increase from April and May. The average July electric bill in Mckinney is about $210, the peak for the year as air conditioning runs constantly to combat the Texas heat.
While exact costs will vary based on home size, cooling equipment, and electricity plans, most Mckinney households see their energy expenses double or even triple in the dog days of summer. Budgeting an extra $100-200 per month for June, July, and August is prudent for those living in single-family homes. Apartment dwellers may see less dramatic spikes but should still plan for higher-than-usual bills.
Why Are Energy Bills So High in Mckinney During the Summer?
Several factors converge to drive up electricity costs in Mckinney in the summer months. The primary culprit is near-constant air conditioning needed to maintain a livable indoor temperature. Even energy-efficient AC units work overtime to cool homes as the mercury regularly tops 100°F outside. Older homes with less insulation and aging ductwork make cooling systems strain even harder.
Other summer-specific energy needs also contribute to higher bills. Pool pumps, extra loads of laundry, fans, and refrigerators all consume more electricity. In Mckinney, abundant sunshine means lights stay on later into the evening. Those with electric vehicles may charge more often for family road trips. All of these small increases add up to substantially higher energy bills.
Utility companies also often charge higher rates in the summer months due to the increased demand on the power grid. Time-of-use pricing, where electricity costs more during “peak” hours like weekday afternoons, can inflate bills further for those without smart thermostats or the ability to shift usage to off-peak times. Mckinney utility costs reflect all of these seasonal swings.
Sample Monthly Bill Breakdown
To illustrate how summer affects specific energy costs, here’s an example of how cooling dominates a Mckinney electric bill in July:
| Category | Percent of Bill |
|---|---|
| Cooling | 55% |
| Appliances | 15% |
| Water Heating | 12% |
| Lighting | 10% |
| Other | 8% |
Based on 1,800 sq ft home with average A/C use
Expect cooling to account for 50–60% of your July energy bill in Mckinney. Air conditioning is by far the biggest contributor to summer energy expenses. Finding ways to reduce AC runtime, even slightly, can make a noticeable dent in monthly costs.
Ways to Lower Summer Energy Bills
While some increase in summer energy costs is inevitable in Mckinney, there are ways to keep bills under control:
- Program your thermostat for 78°F when home and a few degrees warmer at night or when away
- Use ceiling fans to help air feel cooler so you can set the thermostat higher
- Close blinds and curtains during the day to block solar heat gain
- Seal air leaks around doors and windows and add insulation to keep cooled air inside
- Avoid using the oven and limit opening the fridge to prevent fighting the AC
- Shift laundry, dishwashing, and EV charging to off-peak hours when electricity is cheaper
🏆 Energy Tip: Set your thermostat to 78°F during the day and use ceiling fans for comfort. Every degree higher saves 3-5% on cooling costs.
Time-of-Use Pricing in Mckinney
Some utility providers in Mckinney offer time-of-use (TOU) pricing plans. Under these rate structures, electricity costs substantially more during “peak” hours, usually weekdays from 1pm to 7pm. Off-peak hours, which include nights and weekends, have much lower rates.
TOU plans incentivize shifting flexible electricity use, like running the dishwasher or charging an EV, to off-peak times. With some thoughtful changes, a household can shave 10-40% off their summer energy bills by capitalizing on off-peak savings. However, those who can’t realistically avoid peak AC use may pay more under TOU pricing.
Summer Cooling FAQs
How much more are summer bills compared to spring?
In Mckinney, expect your July electric bill to be about double April’s, assuming similar household size and behavior. Hot weather is the primary driver, but higher summer electric rates also play a part.
Does solar reduce summer energy costs?
Yes, having rooftop solar can significantly offset higher summer bills. With Mckinney’s abundant sunshine, a right-sized solar array often generates enough to power the AC during peak times. Any excess electricity flows back to the grid for a credit.
What temp should I keep my house to save energy?
The US Dept. of Energy recommends setting your thermostat to 78°F while you’re home in the summer. Raising it to 82°F overnight or when away for more than 2 hours maximizes savings. With a smart thermostat, you can automate these changes and hardly notice the difference.
Smart Cooling Prep for Mckinney Summers

Before June arrives, prep your home by servicing the AC, sealing leaks, and programming the thermostat. Expect to pay $150-300 per month to cool an average home.
