Summer is around the corner, and it’s shaping up to be a scorcher.
According to the Farmers’ Almanac’s summer 2025 forecast, most regions in the United States can expect the hottest temperatures in recorded history. The Almanac predicts a warm, hot, and muggy summer for most of the nation, except the Northwest region, where more seasonable summer temperatures are expected.
The Southwest and Pacific Northwest are expected to see dry conditions for most of the summer. New England and most areas east of the Mississippi River are on track to have yet another wet summer. Thunderstorms are predicted to be plentiful in the Great Lakes and Midwest region.

Kiplinger talked to home experts on how to prepare your home for this summer’s weather conditions.
1. Tune up your HVAC system
An inefficient HVAC (heating, ventilation, and air conditioning) system can drive up summer cooling costs. If you haven't serviced your HVAC system, hiring a professional HVAC technician to give your system a tune-up before summer begins ensures it will run smoothly during the hot months.
According to Angi data, a tune-up costs an average of $250 — less than half of the cost of the average HVAC repair bill.
2. Change HVAC air filters
“A clean HVAC filter can reduce allergens in your home and help your HVAC system run easier,” Micetich says. For best results, she suggests changing your HVAC filter at least once every three months.
3. Rotate ceiling fans counterclockwise
When used properly, a ceiling fan can help keep a room cool. In the summer, you should set your ceiling fans to rotate counterclockwise. “This will help circulate cool air and push it down into your room, creating a cooling effect throughout,” Kate McKenna, a senior editor at home improvement site The Spruce, tells Kiplinger.
4. Plug air leaks
A poorly insulated house can jack up your utility bill, but you can combat it with a combination of air sealing and proper insulation. Check your home’s attic, windows and exterior doors for gaps, and seal them before the summer months to help keep cooled air inside your home.
Bonus: Adding insulation also means you’ll save money in the winter by keeping warm air inside. Homeowners can save an average of 15% on heating and cooling costs by air sealing their homes and adding insulation in their attic, floors over crawl spaces and basements, the EPA estimates.
5. Program your lawn sprinkler system
Your lawn might need extra hydration to sustain long, hot summer days.
“A professional can help make sure your sprinklers are functioning with proper rotation and power and you’re not over-watering your lawn, as many homeowners are guilty of doing,” says David Steckel, head of product and innovation at Sears Home Services.
For best results, Micetich suggests running your sprinklers in the evening or early morning to avoid the hottest part of the day.
6. Aerate your lawn
Aeration entails making small holes in your yard to allow for better water penetration, helping the soil breathe and soak up nutrients.
You can do it yourself by renting a core aerator from a local home improvement store, or hire a professional aeration service. Depending on the size of your lawn, aeration typically costs from $75 to $205, according to Angi data.
7. Deep clean your outdoor grill
Cookouts are synonymous with summer, so make sure your grill is ready for barbecuing. If you have a gas grill, first scrub the grates with a grill brush, then soak them in a mixture of 2 cups of vinegar and 1 cup of baking soda.
Dust off any cobwebs from your grill, which can cause a flare-up if they ignite, and clean the outside of the lid and bowl with soap and water.
Cleaning methods can vary based on the type of grill you own. Home Depot provides step-by-step cleaning guides for gas, charcoal and pellet grills.
8. Clear out gutters
Heavy rainfall can spell disaster if your gutters are clogged. Clearing out dirt and debris can help prevent water backups.
“This is a project that really should be left to the professionals, as it can be dangerous for the inexperienced and can also cause damage to your home if done incorrectly,” Steckel says.
A professional gutter cleaning costs from $119 to $234, on average, HomeAdvisor reports. (Gutter cleaning for two- and three-story structures tends to cost more than single-story homes.)
9. Keep indoor humidity in check
Generally, your home’s indoor humidity level should stay around 40% to 50% in the summer. Humidity levels of 60% or higher can lead to mold and dust mites, according to the EPA. If necessary, purchase a dehumidifier to draw excess moisture from the air.
10. Consider getting flood insurance
Floods can happen anywhere; more than 25% of flood insurance claims are filed by people who live outside high-risk flood areas, according to FEMA. However, flooding isn’t covered by most standard home insurance policies.
You can purchase flood insurance coverage through the National Flood Insurance Program (NFIP). Nationally, the average annual flood insurance premium is $947, according to NerdWallet; rates for homes in areas with low-to-moderate risk of floods typically cost $628 per year. That’s a worthwhile investment when you consider that the average NFIP insurance claim is over $32,000.
