Back in August I mentioned my fan situation in The House That Smells Like Me. A Scent Journey. That was a footnote. This is the full hearing.
I own air conditioning the way I own a fire extinguisher. I know where it is. I’ve confirmed it works. I’d be a little embarrassed to have to use it.
Everybody else treats it like a utility, like running water. You can sort a neighborhood in July by walking into the houses. Some of them hit you with a wall of cold that smells like the inside of a refrigerator. Mine hits you with a breeze, a low hum, and a curtain doing the wave. One of those houses is a showroom. The other one is lived in.
When people come over and see the windows open and a fan going in the corner, I can watch them do the math. Their eyes go to the thermostat. Then to me. Then back to the thermostat, like it might know something. Somebody always asks, “Is the air not working?” The air is working beautifully. It’s just not coming from HVAC. It’s 76 degrees. Sit down.
Every family has a thermostat rule, and the classic is, “Close the door, we’re not paying to cool the whole outside.” Somebody in your life said that sentence with complete moral authority when you were six, and you couldn’t figure out how the outside got onto the electric bill. I understand now. I just reached a different conclusion. If we’re paying to cool the outside, I’d rather let the outside in for free.
Here’s my case. Air conditioning takes the air already in your house, cools it, and sends it back around. The same air that was in the kitchen at 6 and next to Walter at 7 comes back for another lap. It’s a closed meeting with no new attendees. A breeze brings news. A window fan pulls in whatever the evening has going on. Cut grass. A grill going somewhere down the road. Rain on its way before the forecast admits it. You get a full report on the whole property without leaving the couch.
The setup matters, and cross-ventilation isn’t a phrase. It’s physics. To get a breeze, you need cooler air coming in one side and warmer air going out the other. No exit, no breeze. You just have a fan stirring a hot room. So, I run an intake fan in a room at one end of the floor and an exhaust fan at the far end of the house, and everything in between gets the draft. I also run a double window fan that trades air with the outside, one side pulling in and one side pushing out. Next to my bed I keep a Vornado, which is a fan with a master’s degree. It doesn’t blow at you. It moves the room.
Yes, I know somebody’s about to say bugs. Screens exist. A moth that gets in is a guest. A mosquito that gets in is a guest who doesn’t see morning.
Then there’s sleep. A fan is white noise with a job. The Vornado by my bed moves the air, covers every creak a house makes after midnight, and has never once beeped at 3 a.m. to announce that a filter needs changing. An air conditioner cycles on like it just remembered something, shudders, shuts off, and leaves the room ringing. The Vornado hums one note all night, like a woman humming in the kitchen while she decides what to do about you.
And the upkeep. Filters. Coils. A technician who shows up in a heat wave with the face of a surgeon and a quote like a mortgage. My fan has a cord. If it dies, I replace it for roughly the price of lunch and nobody has to come to my house and look at it gravely.
I’ve got 33 years of office buildings behind me, so I know what the other side of this argument looks like. Every building I’ve worked in kept the thermostat at a temperature meant for storing produce. Women in cardigans in July. A space heater under a desk in August. People running heaters to survive the air conditioning. Somebody paid for the cooling and then somebody paid for the heaters, and I’d love to attend that budget meeting.
Hotels are worse. I travel enough to have a complaint, and the complaint is windows that don’t open. Who is that for? A window that doesn’t open is a framed picture of a window. You can see the weather. You just can’t be included in it. I’ve stood in front of one, pressing on the glass like a woman checking a pumpkin, before I accepted that the only air in the room was the air the building had decided I deserved.
Let’s talk money, because I like a receipt. By one 2026 estimate, a box fan costs about 1.8 cents an hour to run. Central air at full blast costs about 63 cents. Over a 90-day summer, that’s $13 for the fan and $180 to $280 for the air, at minimum. I run a small fleet of fans and I’m still nowhere near $180. The difference buys a very nice dinner. Alone. Medium rare ribeye, good jazz.
There’s a harder number sitting under the joke. A 2020 report from the American Council for an Energy-Efficient Economy, built on 2017 Census housing data, found that Black households spend 43% more of their income on energy bills than non-Hispanic white households. So, when somebody tells me cold air is a basic need, I agree, and I’d like the utility company to agree with us both. A fan isn’t a political position. At those numbers, though, running fans isn’t a quirk. It’s a strategy.
The car is where I’m told I’m at my worst. I almost never touch the AC. Windows down, one hand out riding the wind like an airplane wing, music loud enough that the car next to me at the red light gets a free concert and a little of my business. Then, the federal government weighed in. The Department of Energy says air conditioning can cut a conventional car’s fuel economy by more than 25% in very hot weather, especially on short trips. Their advice is to roll the windows down at lower speeds and use the AC on the highway. So, the (pre-stupid era) government of the United States agrees with me around town and disagrees with me on the interstate. I’m in the fast lane on the interstate. Put your foot on the gas or move to the middle lane, and the Department of Energy can take its advice up with whoever’s behind me.
Then there’s the passenger. There’s always a passenger who says, “Can you put the air on?” in the voice other people save for asking to borrow money. I say, “It’s on. It’s called a window.” They look at me the way you look at someone who just handed you a coupon for a store that closed.
At interstate speed with the windows down, you’re standing inside a hair dryer that’s yelling at you. I turn the music up. The wind loses.
I’m not a fanatic. I’m a woman with a ceiling, and my ceiling is 80 degrees. I also have a calendar. No AC before June 1 and none after October 1, which makes the thermostat decorative for 8 months of the year. Science says a fan quits helping around 95, the point where the EPA says electric fans won’t prevent heat-related illness and the CDC and the WHO say don’t lean on them alone. I beat the experts there by 15 degrees. Older adults sweat less, which means a fan helps them less, which is a rude thing for science to tell a woman on the other side of fifty. At 80, I walk to the thermostat the way you walk into an emergency room. Reluctantly, quickly, and with an attitude.
Walter gets a vote too. He’s a French Bulldog, so his airway is built like a kazoo and he overheats if you look at him wrong. When the house hits 80, the AC runs, he lies directly in front of the vent like it reports to him, and he has never once said thank you. Same story in the Gambia when the night heat and the humidity show up together. A breeze is a wonderful thing until it’s just warm air with ambition.
I’m writing this with the double window fan going and the Vornado turned my way. The room smells like cut grass and a grill going somewhere down the road. A curtain is moving. The central air conditioner is still there, being looked at by no one, off since October 1 and waiting on June. The forecast says it’s supposed to climb this week. I could check how high. I’m not going to. There’s a curtain moving and I’m staying right here.
Fan, AC, or windows down? Who won the thermostat war in your house, and who’s still wearing a cardigan in July? Tell me in the comments.
