Enjoy today's weather — because it isn't going to last. Western Massachusetts already recorded 99°F last week, and forecasters say New England is heading into one of its hottest summers in years. When those 90-degree days arrive at your door, the homeowners who prepared in advance will barely notice. The ones who didn't will feel it in both their comfort and their electric bill.
Why Preparing Now Is the Smartest Move You Can Make
Massachusetts health data shows the first heat wave of the season is always the worst. Your body hasn't adjusted yet, leading to significantly more heat-related emergency room visits than later heat waves — even when temperatures aren't as extreme. The same logic applies to your home. If you wait until it's already 92°F to think about this, you're already behind.
Boston and Southern New England typically see two to three heat waves per summer, and last summer delivered three across many parts of the region. Massachusetts electricity rates are already sitting at $0.30 per kWh — 67% above the national average. Every degree of preparation you make today costs you nothing. Every degree of unpreparedness in July costs real money.
1. Learn Your Peak Hours Before You Need To
This one piece of information can save you $100 to $200 this summer — and it takes 30 seconds to know. Eversource charges its highest rates between 12pm and 8pm Monday through Friday. National Grid's peak window runs 8am to 9pm Monday through Friday. Running your air conditioner, dishwasher, laundry, or EV charger during those hours costs significantly more per kilowatt-hour than any other time of day.
Set a phone reminder right now for 11:45am on weekdays. That's your signal to raise the thermostat, pause the laundry, and let the house coast on the cool air you've already built up. Do this consistently and you'll never think about it again.
Takeaway: Know your utility's peak window. Treat it like a daily schedule, not a crisis response.
2. Pre-Cool Your Home Before Noon — Then Coast
The single most effective air conditioning strategy for a hot Massachusetts day costs you nothing extra. Set your thermostat to 70–72°F before peak hours begin. Let your home absorb that cool air into the walls, floors, and furniture. Then raise it to 76–78°F when peak pricing kicks in and let the thermal mass do the work.
This approach — called pre-cooling — can cut your AC runtime during the most expensive hours of the day by 30 to 40 percent. Your system works hard when electricity is cheap and barely runs when it's expensive.
Takeaway: Cool hard before noon. Coast through the afternoon. Your bill will show the difference at the end of the month.
3. Close Everything by 9am
Once outdoor temperatures start climbing, an open window works against you. Seal up your home before the heat outside exceeds the cool air inside — typically by 9am on a hot day. South- and west-facing windows are your biggest vulnerability, taking direct sun during the hottest afternoon hours.
In Massachusetts, heat often comes with high humidity, which makes hot weather feel significantly hotter than the actual temperature. Keeping that humid air outside matters just as much as keeping the hot air out. Blackout curtains or heavy shades on west-facing windows can reduce indoor heat gain by up to 77 percent compared to uncovered glass.
Takeaway: Think of your home like a cooler. Seal it in the morning, keep it sealed until outdoor temperatures drop below indoor temperatures — usually after 8pm.
4. Check Your Ceiling Fan Direction Right Now
Your ceiling fan has a small switch on the motor housing that most people set once and never touch again. For summer, you want air blowing directly down on you when you stand underneath it — that downdraft creates a wind-chill effect that makes the room feel up to 4°F cooler without changing the actual temperature at all.
The easy test: stand under the fan while it's running. If you feel a clear breeze hitting you, you're set. If you feel nothing, flip the switch on the motor housing and try again. Find the direction that creates that downdraft — that's your summer setting regardless of which way the blades appear to spin.
Takeaway: A correctly set ceiling fan lets you raise your thermostat 4°F with no drop in comfort — cutting roughly 10 percent off your AC energy use every single day.
5. Stop Charging Your EV During Peak Hours
A Level 2 home charger pulling 7 to 11 kilowatts during Eversource or National Grid peak hours is one of the most expensive habits a Massachusetts homeowner can have in summer. A full 60 kWh charge at peak rates costs over $18 in Massachusetts — one of the highest figures in the country. Shift that same charge to after 9pm and the cost drops significantly.
This summer's El Niño-driven heat pattern means more peak demand events, more strain on the grid, and more pressure on peak-hour pricing across New England. Schedule your EV to start charging at 9pm every weeknight and you'll save $300 to $600 over the course of a summer without changing anything else about how you drive. EnergySage
Takeaway: Set your EV charge schedule tonight. Most Level 2 chargers and EVs have a built-in timer in their app. Set it and forget it.
6. Get Your HVAC Serviced Before It's 90 Degrees Outside
The worst moment to discover your air conditioner has a problem is the first afternoon it hits 92°F. HVAC technicians are fully booked within hours of the first heat wave. Scheduling a tune-up now — while the weather is forgiving and calendars are open — costs a fraction of an emergency call and keeps your system running at peak efficiency all summer.
A dirty filter alone can reduce your system's efficiency by 10 to 15 percent, meaning your AC works harder and longer to produce the same result. Clean filters, clear drain lines, and properly charged refrigerant are the difference between a system that coasts through a heat wave and one that runs nonstop and still can't keep up.
Takeaway: Book your HVAC service this week. Don't wait until everyone else is scrambling for the same appointment in July. Lela homelife
7. Solar Owners — Understand What This Summer Means for You
Forecasters expect at least a few notable heat waves this summer, with interior valleys across Massachusetts potentially seeing several stretches in the 90s. Every one of those days is a day your panels are producing at their peak — between 11am and 3pm — which falls directly inside the most expensive pricing window for both Eversource and National Grid customers. EnergySage
While your neighbors are paying top dollar per kilowatt-hour during the hottest part of the afternoon, your panels are covering that load for free or banking net metering credits worth nearly a third of a dollar each. The hotter this summer gets, the more clearly solar proves its value to a Massachusetts household.
Takeaway: If you've been on the fence about solar, pull your last three electric bills and look at your summer usage. That's exactly what the payback calculation is built around.
8. Battery Owners — Enroll in ConnectedSolutions Before Summer Peaks Begin
If you have a home battery and you are not yet enrolled in ConnectedSolutions, do it this week. The program pays Eversource customers $275 per kilowatt and National Grid customers $225 per kilowatt annually in exchange for discharging your battery during peak summer demand events. With El Niño driving a hotter, more demand-heavy summer across New England, the number of those events — and the payment opportunities that come with them — is only going up. EnergySage
Enrollment takes minutes through your utility's website or your battery installer. The summer payment window is open right now. Every week you delay is a week of potential earnings you cannot recover.
Takeaway: Enroll in ConnectedSolutions today. It costs nothing, takes minutes, and pays you for something your battery is already capable of doing automatically.
The Bottom Line
The beautiful weather outside right now is your window to act. Massachusetts data is clear — the first heat wave of the season hits hardest precisely because most people aren't ready for it yet. The eight moves above cost little to nothing and can protect your family's comfort and your electric bill through what forecasters are calling a hotter-than-average summer across all of New England. At Lela Homelife, we help Massachusetts homeowners build homes that handle the heat — from solar and batteries to HVAC tune-ups and EV charging. If you'd like to know what your home could actually save, a free assessment takes 15 minutes and comes with zero obligation.
