8 hacks to cool your home without air-con

1. Cover the outside of your windows

“If you have south-facing windows, you might want to consider putting sheets on the outside of the windows to stop the sun from touching the window and getting into your house,” suggests Kevin Pennington, owner of Lancashire Air Conditioning, who has partnered with Sharps to share home cooling tips.

“It looks absolutely horrendous, but is massively effective. It can reduce the heat gain by up to 80/90% with the right sheet.”

2. Stop any zombie appliances from creating heat

“Try not to leave anything plugged in that produces a lot of heat, such as phone chargers, laptops and desktop computers that are running and charging even though they’re not being used,” says Pennington.

“In addition, I would try to also avoid using/reduce your use of tumble dryers, washing machines and dishwashers in the really hot weather because they produce a lot of heat.”

3. Open windows early in the morning and late at night

“Get those windows and doors open early in the morning, while it’s still cold, then close them throughout the day and reopen them late at night when the air temperature drops,” recommends Pennington.

4. Cook outside

“Using an oven to cook adds a lot of heat to the home which you then need to try and get rid of, so you could try to avoid that by cooking outside by using a barbecue, for example,” suggests Ciaran Murphy, CEO of Dimplex Consumer Products.

Pennington agrees and adds: “Consider having ham, cold cuts and some salad for dinner instead of cooking, as that can be a great way of avoiding putting the oven, the air fryer or the grill on.”

5. Move your bed

Many houses are built from brick to retain heat in winter and if the sun is hitting the wall by your bed all afternoon, the brick absorbs the heat and effectively becomes a large heater,” says Pennington.

“It holds onto that warmth and releases it at night, which causes the room to get significantly hotter than it should be. Therefore, pulling the bed away from the wall should really help.”

6. Point a fan outside

“If the temperature outside is lower than it is inside, having a fan at the window pointing outwards will have the effect of pulling cooler air into the home,” says Murphy. “At the same time, you could also have another fan inside pointing at you to cool you directly.”

7. Make a DIY air conditioner

“If you have a chest freezer in the garage, you can fill an empty ice cream tub with water and freeze it, and then blow a fan on it in your living space,” says Pennington. “As the air blows towards the ice, the ice absorbs heat from it, and it is noticeably cooler.

“However, this is only effective for a short amount of time because eventually it just turns to warm water as you’re blowing energy at it and warming it up.”

8. Give your curtains an upgrade

“You can get reflective backers on your curtains that will bounce away more of that sunlight to help stop some of it from getting into your home,” says Murphy.
