When the Jacksons moved into their 1,800 square foot home in Henderson last year, they were shocked by their first summer electric bill. “I couldn’t believe it was over $300 in July,” said Erica Jackson. “We expected higher costs for A/C, but not double our spring bills.” Unfortunately, the Jacksons’ experience is common—summer energy bills in Henderson often climb to $250-350 per month for an average home.
What Summer Power Costs Look Like in Henderson
As the Jacksons discovered, the average July electric bill in Henderson is about $325. Bills tend to rise sharply in June as temperatures regularly top 100°F, and stay high through September. Over the June–August period, Henderson residents typically pay $250–350 monthly to keep their homes cool.
While exact costs vary based on home size, A/C efficiency, and thermostat settings, most Henderson households see their energy bills double in summer compared to spring. An electric bill that was $140 in April can easily hit $280+ during peak cooling months.
Why Are Energy Bills So High in Henderson During the Summer?

Several factors drive Henderson’s high summer energy costs. The primary culprit is near-constant air conditioning. As outdoor temperatures soar above 100°F for days or weeks, A/C systems and heat pumps work overtime to maintain indoor comfort. Many homes have older, less-efficient cooling equipment and minimal insulation, forcing A/C to run almost nonstop during daylight hours.
Other summer-specific energy needs can include pool pumps, landscape irrigation systems, and extra refrigerator or freezer use for chilled drinks and treats. Electric vehicle charging may also increase if summer road trips are on the agenda. While cooling remains the dominant expense, these combined demands add to already-strained summer electric bills.
Sample Monthly Bill Breakdown
To put Henderson’s summer energy costs in perspective, here’s a typical breakdown for an 1,800 square foot home with average A/C use:
Component | Cost | % of Bill |
---|---|---|
Cooling | $178 | 55% |
Appliances | $55 | 17% |
Water Heating | $36 | 11% |
Lighting | $23 | 7% |
Other | $33 | 10% |
Expect cooling to account for 50–60% of your July energy bill in Henderson. Air conditioning is by far the biggest contributor to summer electric costs. Refrigerators, dishwashers, and other major appliances are the next largest slice at 15-20%.
Ways to Lower Summer Energy Bills
While some summer bill shock is nearly unavoidable in Henderson, there are ways to minimize the damage. Consider these tips:
- Sign up for off-peak billing, if offered by your utility. Shift A/C, laundry and other uses to lower-priced hours.
- Install a smart thermostat to optimize cooling. 🏆 Energy Tip: Set your thermostat to 78°F during the day and use ceiling fans for added comfort.
- Have your ducts inspected and sealed to improve A/C efficiency. Leaky ducts can waste 20-30% of cooled air.
- Plant shade trees or add window awnings to block solar heat. Exterior shade can lower cooling costs 15-35%.
Time-of-Use Pricing in Henderson
Some Henderson utility providers, like NV Energy, offer optional time-of-use (TOU) pricing. Under TOU plans, electricity rates vary based on time of day and demand. Summer weekday peak hours, usually 1pm-7pm, have the highest prices, while off-peak and weekend rates are 30% or more lower.
If your home and habits allow shifting energy-intensive activities like cooling, laundry, and dishwashing to off-peak times, a TOU plan may help lower your summer bills. However, TOU pricing can backfire if your A/C needs to run during expensive peak hours.
Summer Cooling FAQs
How much more are summer electric bills compared to spring in Henderson?
Summer cooling bills are often double spring costs. A $140 April bill typically rises to $280+ in July.
Does solar reduce summer energy expenses?
Yes, a right-sized solar PV system can offset 40-60% of A/C costs. However, solar savings depend on panel output aligning with cooling needs.
What temperature should I keep my house at in summer to save energy?
The US Dept. of Energy recommends setting thermostats to 78°F while at home and 85°F while away. Every degree above 72°F saves 3% on cooling costs.
