If your electric bill just made you do a double take, you’re not alone.
When summer arrives in Arizona, it’s not just the temperatures that soar—it’s utility bills, too.
One month, your home (and your expenses) feel manageable. The next, your AC is running nonstop, your pool pump is working harder, and your electric bill looks like it belongs to someone with a much larger house.
So, why is your electric bill so high in Arizona right now?
There are a few key reasons:
- Your AC runs longer.
- Your home uses more electricity overall.
- Peak hour and seasonal pricing can raise costs.
Let’s break down what’s really behind high summer energy bills.
Your AC Is Doing the Heavy Lifting
In Arizona, air conditioning is not a luxury. It’s survival. And the summer months are when it works the hardest.
During the summer, your AC system has to work against extreme daytime heat, of course. But beyond that, it has to deal with warm nights, direct sun exposure, attic heat, and doors opening and closing as real life keeps happening.
Even if you keep your thermostat at the same setting year-round, your system may need to run much longer in summer months than it does in spring or fall, just to maintain your desired temperature. This is especially true for homes with:
- Older or less-efficient AC units
- Poor attic insulation
- West-facing windows
- Kids home during summer break
This extra runtime doesn’t necessarily mean something is wrong with your system, your house, or your temperature preferences. It just means that your AC is doing exactly what you asked it to do—keeping your home livable even when temperatures are at their highest.
Arizona Homes Use More Power in Summer
Even beyond AC use, Arizona homeowners tend to use more electricity in the summer than they do the rest of the year. That’s especially true for homes with:
- Pool pumps
- Electric water heaters
- Multiple refrigerators or freezers
- EV charging
- Smart devices and electronics running all day
None of these may seem like a huge deal on their own. But together, they add up.
A pool pump running for multiple hours every day. A teenager doing laundry at 4 p.m. A garage fridge fighting to stay cold through 110-degree heat. It all becomes part of the same bill.
How Time-of-Use Plans Affect Your Energy Bill
Here’s where things get a little more complicated.
Many Arizona homeowners are on rate plans that raise electricity costs during certain peak hours. For example:
- APS has time-of-use plans with higher “on-peak” rates from 4–7 p.m. on weekdays.
- SRP also offers plans that encourage customers to use less energy during peak windows like 5–10 p.m. or 6–9 p.m. (depending on the plan).
In other words, your energy bill not only reflects how much energy you use; it also reflects when you use it. So even though homeowners may be careful to use less energy overall, their timing may be working against them.
This is especially true for appliances with high energy use—like a dryer, dishwasher, oven, pool pump, or EV charger. Using these things during peak hours can have a significant impact on your energy bill.
Summer Rates and Rising Energy Costs Add to the Pressure
Part of the reason your summer energy bill feels higher likely has nothing to do with your usage, but rather with the rising cost of energy—both seasonally and generally.
Many utility plans in Arizona use seasonal pricing, with energy actually costing more in the summer than it does in the cooler months. Both APS and SRP structure their residential price plans around this seasonal usage.
Translation: your home may be using the most energy at the time of year when energy is priced the highest.
That’s a frustrating combination. And it’s not the whole picture.
In fact, energy costs have been moving upward more broadly as well.
According to the U.S. Energy Information Administration, average U.S. residential electricity revenue per kilowatt-hour in March 2026 was up 10.2% compared to March 2025.1
Regardless of the many factors that may affect an energy bill for any one specific home, there is certainly a bigger trend at play. So if your bill feels heavier than it used to—you’re not imagining things.
How to Lower Your Electric Bill in Arizona
Because there are so many variables in this equation, there isn’t really one simple way to ensure that your Arizona summer energy bill is lower. But there are a couple practical things you can try to take some of the pressure off.
1. Check your utility plan
Start by getting familiar with your utility plan. Are you on a basic plan, time-of-use plan, demand plan, or solar-specific plan? Knowing your plan—including when your energy costs the most and how much it costs—can help you understand whether your biggest issue is total usage, peak-hour usage, demand charges, or a mix of all three.
2. Shift big energy use out of peak hours
If your plan includes peak hours with higher energy costs, try to run the dishwasher, laundry, pool pump, and EV charger outside of these peak windows when possible. And yes, these small changes in timing really do matter, especially in the summer.
3. Give your AC a fighting chance
AC maintenance is crucial if you want your system to perform its best when you need it the most. If your AC unit is older or has struggled in the past, it may be worth having it checked to make sure it’s in shape for the hottest stretch of the season.
Other things you can do to help your AC out:
- Replace filters regularly
- Keep vents clear
- Seal obvious air leaks
- Keep doors and windows closed as much as possible
- Use blinds or shades during the hottest parts of the day
4. Watch the pool pump
Pool pumps run in the background, making them easy to forget. But in summer, they typically need to run for longer stretches of time, which means they can be a meaningful part of your bill.
Make sure your pool pump is running at times that match your utility plan and your family’s needs for your pool.
5. Use a smart thermostat wisely
A smart thermostat can help keep your energy bill in check—but only if it’s set up around your real schedule and rate plan.
For example, some homeowners prefer to pre-cool their homes before peak hours begin, reducing energy use when it costs the most.
With the right settings for your smart thermostat, you can easily make adjustments that have a positive impact on your utility bill without making your house miserably warm.
6. Look at your whole-home energy picture
Figuring out your home’s energy usage can feel like guesswork, but it doesn’t have to be. An energy monitor, energy audit, or professional review can help identify where your home is using the most power. From there, you can focus on making changes that will actually make a difference.
Can Solar Lower Your High Arizona Electric Bill?
The honest answer is: it depends.
For Phoenix homeowners who want to make a real dent in their summer energy bills, solar may seem like the ultimate solution.
Yes, solar is one way for a homeowner to reduce how much electricity they need to buy from the grid—especially during the sunniest (and most expensive) months of the year.
Still, solar is not a magic wand that will instantly lower all your energy costs. And it’s not the right option for every house.
Solar probably makes more sense for your home if:
- Your summer bills are consistently high
- Your roof gets strong sun exposure
- You plan to stay in your home long enough to benefit from the savings
Even if you decide to explore solar, a good solar setup is not a one-size-fits-all package. A truly beneficial home solar setup starts with designing the right system for your specific home and lifestyle.
Sometimes that means a larger system designed to offset most of your energy use. Sometimes it means a smaller system paired with energy management technology. Either way, your system should be based on your real energy usage, roof layout, utility structure, and long-term goals—not whatever happens to lead to the biggest sale for the solar company.
