If you’ve ever wondered why 78 degrees became the “ideal” summer thermostat setting, you’re not alone—and in this summer’s intense heat, many New Englanders are questioning that number more than ever.
Back in 2019, ENERGY STAR (a joint program of the U.S. Department of Energy and EPA) recommended setting your thermostat to 78°F during warmer months to balance comfort and energy efficiency. But five years later, with heat waves making headlines and more people spending time at home, that number feels... well, a little too toasty.
What New Englanders Are Actually Doing
Despite the energy-saving advice, most Americans keep their homes closer to 71°F, according to a Consumer Reports survey. Why? Because while you’ll save roughly 3% on your cooling costs for every degree you raise the temperature, comfort still reigns supreme—especially during a sticky Boston summer.
So, What’s the Right Temperature?
According to DR Richardson, a Massachusetts-based expert and founder of Elephant Energy, there’s no one-size-fits-all answer. Every home (and homeowner) is different. Your ideal temperature should depend on:
-
Your home’s HVAC efficiency
-
The layout of your home
-
Your daily routines and sleep habits
-
Whether your system provides even cooling across rooms
It might mean 70°F during the day and a cooler 68°F at night—or maybe a couple degrees warmer if your system struggles during peak hours.
Heatwave Tips from Local Pros
With Boston and much of New England expecting hotter-than-average temperatures this summer, HVAC specialists like Alex and Steve (featured on Boston 25 News) are urging homeowners to be proactive. Here's their expert advice to help you stay cool and cut costs:
-
Run fans frequently (especially if you have a Nest or Ecobee) to circulate air and prevent hot spots upstairs.
-
Use blackout curtains during the day and limit AC use in rooms flooded with sunlight.
-
Check your filters monthly and rinse outdoor vents to remove debris and improve airflow.
-
Schedule annual HVAC maintenance—March and April are best, but even now is better than never.
-
Stick to the cooler areas of your home during peak heat, like shaded rooms or basements.
-
Think mini-splits if your current system isn’t cutting it—these flexible units offer zoned comfort without the need for full ductwork.
Cutting Electricity Costs Without Losing Your Cool
This summer, the average U.S. electric bill is expected to hit $787—up nearly 20% from just three years ago. In a region like New England, where older homes and inefficient systems are common, being strategic about your cooling could mean serious savings.
Here are some impactful ways to use less electricity while keeping your home comfortable:
✅ Close blinds during the day to reduce solar heat
✅ Seal air leaks around windows and doors
✅ Use fans to feel cooler without lowering the AC
✅ Change air filters monthly during the summer
✅ Upgrade to a programmable thermostat for smarter cooling
✅ Add insulation (especially in the attic) to lock in cool air
✅ Plant shade trees or install exterior awnings
✅ Unplug unused electronics to avoid “phantom” energy use
Want to take it a step further? Installing a high-efficiency HVAC system or heat pump, or adding smart home upgrades can not only lower your bills—it can also increase your home’s resale value. According to Freddie Mac, homes with energy-efficient features sell for 3% to 5% more on average.
