The Cheapskate’s Guide to Surviving without Air Conditioning
It’s that time of year again. The mercury is climbing…and staying there, way up at the top of the thermometer. But running an air conditioner at full blast to combat the heat can be very expensive, and for those of us on a budget, the resulting bill can be crippling.
So what can you do when the heat is on, while still maintaining a reasonable electric bill? These simple tips can help you keep your cool on even the hottest day.
Avoid heating up your house.
Many of the things that we do without thinking are unconsciously adding 5-10 degrees of heat to an already uncomfortably warm house. In the hottest part of the year, I avoid running certain appliances. Some folks say to run those heat-creating appliances at night, but I depend on the cool nighttime temperatures to bring my home down to a comfortable level for the next day.

In the summer, avoid or limit your use of the following:
- Dryer: Make use of the hot sun and hang your laundry outside. Not only will you have fresh, clean smelling laundry that no dryer sheet can top, it’s free and it won’t warm up your house! If you have a small yard, look at these space-saving umbrella style clotheslines. If you live in an apartment, these inexpensive drying racks will fit on a balcony and fold right up for easy storage when they aren’t in use.
- Washer: Washing machines can also generate a great deal of heat and humidity, particularly if you wash your clothing in hot water. If at all possible, wash your laundry in cold water during the hottest parts of the year.
- Oven: Rely on outdoor cooking methods,(solar cookers or barbecues) or if that isn’t an option, use your slow cooker. (Click HERE to learn more about hot-weather cooking methods)
- Dishwasher: Think about how hot the dishes are if you reach in the second the dishwasher is finished running to grab a plate. Now, consider how much heat that adds to your house! It is much more efficient to wash your dishes by hand in the summer. A sink full of soapy water and one full of rinse water will add far fewer degrees to the temperature of your house. (Rinse water does not have to be hot, either.)
- Lighting: Some bulbs, particularly halogen bulbs, generate a great deal of heat. If a lightbulb is hot to the touch, it’s adding to the temperature of your house. Look into LED bulbs or compact fluorescents to keep your home cooler.
Cool it down naturally.
Air conditioning is a fairly recent invention. It is only in the past few decades that most people decided that air conditioning was a “necessity.” Unfortunately now, most houses are built without consideration for natural cooling. If a new home is being built, chances are, it will have central air conditioning. While this is a nice perk, it’s important to note that in the midst of a power outage, these houses with stunning floor to ceiling windows are going to be hotter than blue blazes. Older homes have a lot of advantages over their newer counterparts when it comes to cooling them without air conditioning.
Houses that are 100+ years old are often perfectly comfortable in all but the very hottest of weather. The windows are placed across from one another throughout the homes, for optimum cooling and cross-breezes.
Here’s the technique that keeps our home pleasant when the mercury climbs into the 90s:
- As soon as it starts to cool down in the evening, I open all of the windows and blinds. There’s a ceiling fan in every room and those run all the time.
- We also have some window fans which we turn on in the evening. These pulls in the lovely cool night air.
- In the morning, the house is so cool that sometimes you need a hoodie during that first cup of coffee!
- I then go around and close all of the windows and blinds. This keeps out the heat and keeps the house from passively warming up from the sun. (In the winter, I do the opposite of this in order to heat the house using the sun.) The ceiling fans continue to run all day and we have small oscillating fans to use in the rooms we are in.
- Rarely does the temperature in my house ever rise about 85 degrees. That’s pretty warm but certainly not intolerable.
Evaporative cooling for humans
Here’s the thing – we have basically evolved ourselves right out of being able to cool ourselves down without the aid of an air conditioner. We go from an air-conditioned home to an air conditioned car to spend the day in an air-conditioned office and have lunch at an air conditioned restaurant. Then we drive our air conditioned car back home, suffer through perhaps 20-30 minutes of necessary outdoor work, and then go in, gasping for air, to cool off in front of another air conditioner.
Our bodies no longer know how to cool themselves because they never have to do so. We’re sort of like those cave fish that never experience light, so they evolved to no longer have eyeballs. We suffer far more in the heat than previous generations ever did, because we never allow our bodies’ cooling mechanisms to be used. That’s why my family has dramatically reduced our use of the air conditioner. Think about it: what would happen in a longterm grid-down scenario? People will drop like flies of heat-related illnesses.
But you can train your body to tolerate heat again.
A good friend of mine lives in the desert and has no air conditioning. It regularly gets to 110 degrees in his home and he is barely affected. That’s because his body’s cooling system is efficient – he uses it on a regular basis
On the opposite end of the spectrum, I have many other friends who do not tolerate heat well at all. (I used to be one of those people myself, but while I definitely prefer cooler temperatures, I have managed to recondition my body to withstand hot weather with less discomfort.)
I’m not suggesting that you go run a marathon in the midst of a heatwave or endure 110 degree weather with nothing but an oscillating fan. But don’t be afraid to sweat a little.
There’s a very good reason that people need to stop being so uncomfortable with sweat. Sweat is the human body’s evaporative cooling system. Here’s the rundown on how the human body cools itself from an article called “The Physics of Sweating“:
When we sweat, our skin and clothing become covered with water. If the atmospheric humidity is low, this water evaporates easily. The heat energy needed to evaporate the water comes from our bodies. So this evaporation cools our bodies, which have too much heat. For the same reason splashing water on ourselves when it is hot feels good. Being wet during cold weather, however can excessively chill us because of this same evaporation effect…
When it is very humid, our sweat does not evaporate as easily. With the body’s primary cooling process not working efficiently, we feel hotter. That is why a hot humid day is more uncomfortable than a hot dry day…
Despite the fact that sweating can make us feel unpleasantly sticky, the principles of thermal physics make sweating a very important mechanism for cooling the body in hot weather. (source)
So, by allowing yourself to get hot and letting your body cool itself, you can build up a tolerance to the heat. By avoiding heat and sticking to chilly air-conditioned rooms, you will be far more uncomfortable in a situation in which air conditioning is not available.
When the grid fails…
Speaking of those times when air conditioning is not available…what can you do if the power goes out during the biggest heatwave of the summer?
The situation that comes to mind is the Derecho storms that struck metro DC in 2012. The power was out for a week in the midst of a terrible heatwave and quite a few people died from heat-related ailments. Many others were sick, suffering from heat exhaustion and heat strokes, and millions of others were miserably uncomfortable. As mentioned above, homes really aren’t built to be cooled without air conditioning anymore, and humans aren’t used to letting their bodies cool themselves.

Do you have air conditioning at your home? Do you run it all the time? What are some techniques that you use to keep cool in hot weather?
