Thermostat Wars: How to Set the Best Temperature This Summer
It’s a familiar scene in households throughout Southern California: one person walks by the thermostat and drops it to a crisp 68°F, hoping for fast relief from the heat. Minutes later, someone else nudges it back up to 75°F, trying to save on energy costs—or because they’re freezing under a ceiling fan. And just like that, the thermostat wars begin. These quiet battles over comfort and control play out daily in homes everywhere, especially during the height of summer when temperatures soar and energy bills follow suit.
At Shalom Heating & Air, we see it all the time. Finding that perfect indoor temperature is about more than just preference—it affects your comfort, your monthly utility bills, your HVAC system’s performance, and even the lifespan of your equipment. Striking a balance between staying cool and keeping costs under control can feel like a real challenge, especially when multiple people in the house have different comfort levels—and with summer 2026 shaping up to be another scorcher across SoCal, that challenge is only growing.
But the good news is that you don’t have to pick sides. With the right strategy and a few smart adjustments, you can manage your thermostat in a way that keeps everyone relatively happy—without wasting energy or putting unnecessary strain on your air conditioner. Whether you’re dealing with a household of thermostat tamperers or just want to optimize efficiency this season, we’re here to help you take control—and restore peace to your home this summer.
Tips to Stay Cool Without Cranking the Thermostat
Finding balance is about more than just the numbers. Use these smart strategies to stay comfortable this summer:
These habits support your cooling system and help maintain comfort even at higher thermostat settings. Small, consistent changes throughout your home can make a noticeable difference in how cool and comfortable your space feels—without touching the thermostat dial.
What’s the Ideal Temperature for Summer?
According to the U.S. Department of Energy, the ideal thermostat setting for summer is 78°F when you’re home and awake. This temperature keeps most people comfortable while helping reduce energy consumption and avoid unnecessary strain on your air conditioner. That guidance remains consistent heading into 2026, and it’s a solid benchmark whether you’re dealing with a mild coastal breeze or a full-on SoCal heat event.
When you’re away from home, setting the thermostat 7–10 degrees higher (around 85°F) can help lower your cooling bill without affecting comfort. If you have a programmable or smart thermostat, setting temperature schedules is a simple way to automate these changes—so your home is already cooling down by the time you walk through the door, without running the AC at full capacity all day.
Why Not Set It Lower?
We get it—78°F might not feel cool enough, especially during a SoCal heatwave. But every degree below that mark increases your energy use by about 3–5%. So, if you’re setting the thermostat at 70°F all day, you’re likely driving up your monthly bill far more than you might expect—and with energy costs continuing to rise in 2026, those extra degrees add up fast.
Lower settings can also cause your AC system to cycle more frequently or run constantly, leading to faster wear and tear and a greater chance of a breakdown when you need it most. That kind of strain shortens the lifespan of your equipment and can turn a minor maintenance issue into a costly repair call in the middle of summer.
Smart Thermostats: A Peacekeeper in the War
Want to end the thermostat battle for good? Consider upgrading to a smart thermostat. These devices learn your habits, automatically adjust temperatures, and allow remote control via smartphone. They also provide energy usage data, helping you make smarter decisions about cooling. Many of today’s models also integrate with home automation systems and voice assistants, giving you even more flexibility and control over your comfort.
Our team at Shalom Heating & Air installs and configures smart thermostats that work seamlessly with your current HVAC system—so you can enjoy both comfort and control. Whether you’re upgrading an older unit or setting up a brand-new system in 2026, we’ll make sure everything is dialed in from day one.
