HOW TO KEEP YOUR HOME COOL IN THE SUMMER?
It’s that time of the year again – the sun’s blazing, temperatures are soaring, and your house feels more like a sauna than a sanctuary. Sound familiar? Whether you’re dealing with your first proper heatwave in your new build, or you’ve been through a few sweaty summers, knowing how to keep your home cool during summer isn’t always easy.
But don’t worry – staying comfortable doesn’t mean you have to break the bank installing air conditioning. With a few cheeky tricks and a little bit of know-how, you can create a cool, comfortable space that you’ll actually look forward to coming home to at the end of a hot day.
What’s the fastest way to cool a hot house?
When your house feels like an oven and you need results fast, it’s all about smart airflow and blocking out the heat. One of the quickest and easiest fixes? Close the curtains or blinds on any windows that catch the sun – you’d be surprised how much heat builds up just from sunlight streaming through the glass.
Once the temperature outside drops below what it is inside, open windows on opposite sides of your home to create a cross-breeze. This helps shift that warm, stuffy air and brings in some much-needed freshness. If you’ve got fans, position them strategically – one pulling cool air in from a shaded window, another pushing hot air out.
And here’s a handy little trick: pop a bowl of ice in front of a fan. As it melts, the fan will blow a cooler breeze around the room – a simple, budget-friendly way to take the edge off the heat.
Should you open or close windows in hot weather?
It’s a common question – and surprisingly easy to get wrong. The answer? It all comes down to timing. When it’s hotter outside than it is indoors (usually mid-afternoon), keep those windows firmly shut. Opening them just lets in all that heat – and before you know it, your home’s a sauna!
As soon as the sun dips and the outside air cools below your indoor temperature, that’s your moment to throw those windows wide open. Timing’s everything here – keep an eye on the weather and plan ahead. If you know it’s going to be a scorcher, close your windows and curtains before heading out for the day.
How can I keep my house cool without AC?
If you’ve just moved into a new home, you might be wondering, “Do new build homes stay cool naturally, or will I need some extra help?” Not everyone has air conditioning, and even if you do, running it constantly can send your energy bills through the roof. Luckily, there are plenty of ways to keep things comfortable without cranking up the air con. Here are our best tips on how to keep your home cool naturally
- Be smart with your windows and doors
During the day, keep curtains and blinds closed on south and west-facing windows – these get the most intense sun. Heavy curtains or blackout blinds are your best friends here. At night, open windows on the coolest side of your house (usually north-facing) and close doors to hot rooms to prevent warm air from spreading.
- Make the most of your fans
Got a ceiling fan? Make sure it’s spinning counter-clockwise in summer – that pushes cooler air down. If you don’t have ceiling fans, portable fans can be just as effective when positioned correctly. Try the ice trick we mentioned, or point a fan out of a window during the hottest part of the day to push hot air outside.
- Avoid creating heat
Your oven, washing machine, and even light bulbs are all pumping out heat. Try cooking outdoors when you can, wait till the evening to run appliances, and swap out old bulbs for LEDs – they run much cooler and save on energy too.
- Create cool zones around your home
Rather than trying to keep the whole house chilly, focus your efforts on one or two rooms. Close the doors to any spaces you’re not using, add draught excluders to keep the cool air where you want it, and spend time in north-facing rooms – they tend to stay naturally cooler throughout the day.
- Think outside the box
Sometimes it’s the simple things that help the most. A quick cold shower, a damp flannel on your neck, wrists, or ankles (areas where blood vessels are closer to the skin, helping you cool down quickly), or even popping your pillowcase into a clean plastic bag and then in the freezer for a few minutes before bed – they’re all easy tricks that can make you feel a whole lot more comfortable when the heat’s relentless.
Are fans ineffective during a heatwave?
Here’s the thing – fans don’t lower the temperature, they just move air around. So if all they’re doing is blowing hot air back at you, it can feel a bit pointless. But used the right way, fans can still make a big difference – and learning how to keep your home cool in summer often comes down to smart fan placement.
Fans are great for helping your body cool itself down. When air moves across your skin, it speeds up evaporation – and that’s what helps you feel cooler, even if the room itself isn’t any colder.
If you’re curious how to keep your house cool in a heatwave, try using fans to create a flow of air through your home. Position one to draw in cooler air from a shaded spot, and another to push warm air out. This kind of setup can help circulate air more effectively and help drop the temperature inside.
At night, fans can be especially helpful by circulating the cooler evening air and preventing heat from settling in your room, making it easier to sleep comfortably. Knowing how to keep a new build cool at night is key to enjoying a comfortable, restful sleep during warmer months.
How do I stop my house from getting so hot in the first place?
When it comes to summer heat, prevention really is the best approach. If you’re thinking about how to keep your home cool in summer, the best approach is to stop the heat from building up in the first place – rather than trying to cool everything down once it’s already sweltering inside.
Start by blocking out the sun before it even hits your windows. Outdoor options like shutters, an awning or external blinds are ideal, as they stop the heat before it hits your windows. If you’ve got a garden or patio, add a pergola with climbing plants or tall, leafy greenery – it’s a natural way to keep things cooler while adding character to your garden. For more ideas like this, take a look at our guide.
If none of these are an option, reflective window film or even well-fitted blackout curtains can still make a real difference. Sacrificing a bit of natural light is often worth it when you’re focusing on how to keep your home cool in summer.
A well-insulated home keeps warm air out just as well as it keeps heat in during colder months. If you’re in a new build home, you’ve likely got the best insulation possible (alongside other energy efficiency features), but if you’re in an older property, it’s worth checking your loft and wall insulation.
Everyday habits also matter. Avoid using your oven during the hottest part of the day, and try not to run too many heat-producing appliances at once. These small tweaks can help keep your indoor temperature down.
