Arizona homeowners face a unique challenge when it comes to setting the thermostat. With scorching summers that regularly reach triple digits and cooler desert winters, finding the best house temperature in Arizona isn’t always straightforward. The right thermostat setting can make your home more comfortable, protect your HVAC system, and reduce energy bills.
So, what temperature should you keep your house at in Arizona? Today on the blog, our Mesa HVAC Professionals are breaking it down by season and by day vs. night.
Best House Temperature in Arizona During Summer
Summers in Phoenix, Mesa, and the surrounding areas are hot, dry, and relentless. Running your air conditioner constantly can put strain on the system and your wallet, but you also don’t want to sacrifice comfort.
Daytime Summer Settings
The U.S. Department of Energy recommends keeping your thermostat at 78°F when you’re home during the day in summer. This strikes a balance between comfort and efficiency.
If you leave for work or errands, you can bump the thermostat up to 85–88°F to reduce energy use. With a smart thermostat installation in Mesa, you can program these changes automatically so your home cools back down before you return.
Recommended setting: 78°F when home, 85–88°F when away.
Nighttime Summer Settings
When the sun sets, desert temperatures drop quickly. Many Arizona homeowners find comfort keeping the thermostat around 74–76°F at night for better sleep.
If you’re willing to use ceiling fans in the bedroom, you can keep the thermostat closer to 78°F to save money without sacrificing too much comfort.
Recommended setting: 74–76°F at night (78°F with fans for energy savings).
Best House Temperature in Arizona During Winter
Arizona winters are mild compared to other parts of the country, but nights in December and January can get surprisingly chilly, especially in Mesa, Chandler, and Gilbert.
Daytime Winter Settings
For winter days, the DOE recommends setting your thermostat to 68–70°F while you’re home. If you’re out for most of the day, lowering the thermostat to 62–65°F can save energy.
Recommended setting: 68–70°F when home, 62–65°F when away.
Nighttime Winter Settings
Most people sleep better in cooler conditions. Lowering your thermostat to 65–66°F at night can save on heating bills while still keeping you cozy under blankets.
Recommended setting: 65–66°F at night.
