12 Best Tips for Keeping Your House Cool With or Without AC

Summertime may bring many wonderful things but the extreme heat is not one of them. For many using air conditioning is not affordable nor available. Here are some tips for keeping your house cool in the summer heat, with or without AC. We use these techniques in steamy South Carolina to reduce our air conditioning bill.

Note: See the post “Heat Stroke – Symptoms, Treatment and Prevention” for more tips on staying safe in high temperatures.

#1 – Dehumidify

If you live in an area with dry heat your body perspires, your sweat evaporates, and you cool off – just the way nature intended. If you live in an area with lots of humidity (which I do) you sweat and it doesn't evaporate. Instead it soaks your clothes leaving you feeling hot, wet, sticky, and miserable.

To feel cooler in high humidity:

Wear loose cotton or other natural fabric that breathes
Choose breathable bedding such as cotton or bamboo
Use a dehumidifier

A dehumidifier helps remove excess moisture from the air, which leaves you feeling cooler even in hot temperatures. You can find dehumidifiers at most big box stores, Craigslist, classifieds, and online. Get a small dehumidifer on Amazon.

#2 – Unplug

Everything you plug into a socket produces heat. Unplug all unnecessary appliances or electronics when not in use. Even those little red glowing lights that stare at you in the middle of the night indicating the item is turned off drain energy and produce heat. Turning something off is not enough – unplug.

#3 – Use Natural Light and High Efficiency Lighting

Take advantage of daylighting or use energy efficient light bulbs, such as LEDs, in your high use areas. A traditional 1oo watt light bulb can increase the heat by 11 degrees per hour in a small room.

Some utilities offer rebates on LED lightbulbs, making them more affordable. You can view a list of LED rebates by region and bulbs that qualify for rebates at LED Light Bulb Rebates | ENERGY STAR LED Rebates.

#4 – Don't Cook or Cook Outdoors

During the summer months, try to pre-plan meals so that you don't need to use the oven during the day. Either cook on the grill, in a microwave, or in a crock pot. If you have to use the oven, try to cook your meal before noon or after the heat of the day. I would suggest around 4 pm.

Editor's note: GNOWFGLINS has an e-course on outdoor cooking options include using portable appliances outdoors, propane camp stove cooking/canning, charcoal grill, solar oven, open fire cooking, smoking, and more.

#5 – Close your blinds from late morning until early evening

“Let the Sun Shine In” is a cute song for children, but not helpful for keeping your home cool. Close your blinds from late morning until early evening. This simple act can keep a room 10-15 degrees cooler.

You can purchase blackout shades, use window tint film on your windows (easy to install), or good blinds. If covering your windows during the day makes it too dark, you can lower the top of your shades 6″ from the top of the window to let light in but not the heat.

#6 – Use Ceiling Fans – The Right Way

Did you know there is a right way and a wrong way to use your ceiling fan?

The base of your ceiling has a small switch that changes the direction of the air flow. During the summer months your ceiling fan should blow forward in a counter-clockwise direction, forcing air down and making you feel cooler. During the winter months your ceiling fan should blow in a clockwise direction circulating the air through the room without blowing directly on you.

#7 – Shade the outside of your windows

A completely dark house during the summer with all of the shades closed makes me depressed and drives me crazy. My husband, (aka energy police who I swear has some vampire blood running through him) would paint our windows green polka-dots if it saved on our electricity, so we made a compromise. I found this very affordable and stylish shade that we installed on the outside of our house over our windows that still lets the light through, but blocks the heat. You can click on this link to see the one we bought. You can also put up an umbrella outside your window to block the afternoon sun and pretend you're at the beach!

This cool triangle shade keeps our dinning room cooler without blocking all of the natural light.

#8 – Vent the Hot Air Out

Use stove top vents, bathroom and laundry room vents to dump hot, humid air from cooking and showering outside.

Being frugal and trying to save on your electric bill isn't just about your wallet. With every watt you save you are reducing your environmental impact.

#9 – Cool Only One Room or Get a Personal Cooling Fan

Close off rooms that are not in use, and focus your cooling efforts only where you need them. Cold air fans and personal fans targeting a small area use a lot less energy than cooling an entire home. This portable handheld fan comes with a rechargeable battery to provide cooling in your home or on the go.

#10 – Plant Shade

This takes some time to establish and a little bit of planning but will provide you win-win results. A tree in full bloom can block over 70% of solar radiation from entering your home. Sun-loving, shade providing plants, trees and shrubs in front of windows that receive the afternoon sun to cool down your house and add beautiful landscaping to your yard.

Keep any trees/plants in pots that need to be brought in during winter months or that have an aggressive root system.

Heat Tolerant Plants that Help Provide Shade:

Sunflowers
Corn
Banana Plants
Palms
Cannas
Dwarf Fig tree
Lemon Grass
Crape Myrtle Tree
Mimosa tree

Editor's note: In cooler areas of the country, just about any deciduous plant will do.

#11 – Cool Your Roof, Cool Your Home

Cool the top of your house, that is. Have you ever gone out in the sun in a black t-shirt? Or thought about why DIY solar heaters are painted black? Because they absorb heat. So why are all shingles black?

Most shingles are black because they are made out of tar. Cool Roofs are ones that reflect sunlight. They stay cool and reduce the amount of heat transferred to the home. According to the CRRC (Cool Roof Rating Council) if you do not have air conditioning, Cool Roofs can drastically reduce a home's internal temperature. If you do have air conditioning, adding a cool roof can save the you up to 15% off your cooling bill.

So how do you get a cool roof? One of the most affordable ways is to paint your roof with a light colored paint specifically for roofs. Almost every type of roofing can be painted, even shingles, but before you start slinging a paint brush make sure you check with your roofing manufacture to see if painting it voids your warranty.

#12 – Invest in Better Doors, Windows and Insulation

While you're checking out the roof, consider more energy efficient options for windows, doors and insulation. Better insulation and tighter seals will help you keep your home cooler in summer and warmer in winter with less energy.
