Setting the House Up for Warm Weather

Do the window routine before you buy a single fan. Most houses get hot in summer because of heat that arrives through glass during the day and then has nowhere to go at night, and no amount of air movement fixes a room that has been absorbing afternoon sun for five hours. The warm season swap in my house is mostly about timing and fabric, with the fans doing the last twenty percent.

Here is the changeover, in the order I do it, usually over one Saturday in late spring.

The daily rhythm that does the heavy lifting

The habit is simple and it feels wrong the first few days. Shut the house up during the hot part of the day, and open it wide once the outside air is cooler than the inside air.

• Morning. Windows open on both sides of the house while the air is still cool. Get as much of that air through as you can.
• Late morning. Close the windows on the sunny side and pull the blinds or curtains there. Keep the shaded side open if there is a breeze.
• Afternoon. The sunny side of the house stays shut and covered. This is the part people resist and it is the part that works.
• Evening. Once it is cooler outside than in, open everything and get a cross draft going. A fan in a window pointing out, on the warm side, pulls the hot air out and drags cool air in through the other windows.

I keep a small thermometer just outside the back door and one in the hallway, which sounds fussy and takes the guessing out of when to open up. Some evenings it is much later than it feels.

The fabric swap

Heavy curtains come down and go into storage. Sheers go up on the windows that need daytime privacy, and the blackout panels stay in the bedroom, since west light in the evening and early sunrise are both worth blocking.

Rugs are the change I underestimated for years. Taking the wool rugs up in the living room and the bedroom makes those rooms noticeably cooler underfoot and easier to keep clean when doors are open and dust is blowing through. They get rolled with the pile facing in and stored on their sides rather than flat, because a rug stored flat with things on top of it develops a crease that never comes out.

Bedding goes light in the same session: percale sheets, the light duvet insert, and the wool blanket out of the rotation entirely.

Storing a rug flat under a stack of boxes is how you get a permanent ridge across it. Roll it pile in, stand it upright, and it comes back out in the autumn looking like nothing happened.

Fans, placed properly

Fans do not cool a room. They cool a person, by moving air across skin, which means a fan running in an empty room is doing nothing but adding a small amount of heat from its motor. That one fact changed how I use them.

What works in my house:

• A box fan in a window on the hot side of the house, facing out, running in the evening. That is an exhaust setup, and it moves far more air out of the house than a fan blowing inward moves in.
• A ceiling fan set to turn counterclockwise in summer, pushing air down. If you cannot tell, stand under it, and you should feel a direct breeze.
• A small fan aimed at where people actually sit, on low, rather than a large one aimed at the middle of the room.

Turn them off in empty rooms. I say that to myself constantly and I still find the bedroom fan running at four in the afternoon.

Heat you are making yourself

Warm season prep includes moving what generates heat. The oven is the big one. From June onward I cook more on the hob, outside, or not at all, and if I do bake I do it early in the morning rather than at six in the evening when the house is already at its peak.

The dryer is the second one, and it is the easy win, since a drying rack outside or by an open window costs nothing and does not vent heat and moisture into the house. Switching over is part of my changeover day: the rack comes out from behind the basement door and lives in the back room for the season.

Incandescent bulbs, if any survive in your house, run genuinely hot. Mine are down to one fixture in the hall and I keep meaning to change it.

The rest of the changeover list

• Wash and swap the entry mats to the lighter set.
• Check the window screens for tears before you need them, and repair or replace before the first warm night with insects around.
• Clean the fan blades and the ceiling fan tops, which are furred with dust after a winter of sitting still.
• Move the heavy throws off the sofa arms and into the storage basket.
• Reverse the ceiling fan direction while you are up there with a cloth.
• Check that the dehumidifier is off and the basement is not being cooled and dried at cross purposes.

What I stopped bothering with

I used to do a full deep clean as part of the summer changeover, on the theory that it was the season for it, and it turned a two hour job into a lost weekend every year. Now the swap is the swap: fabric out, fabric in, fans placed, screens checked. The deep cleaning happens on its own schedule when a room needs it.

I also stopped storing the heavy curtains and rugs in the attic, which in summer becomes hot enough to be hard on wool. They go in the bottom of the wardrobe in the spare room instead, and they come out in October smelling like nothing at all, which was never true when they lived upstairs.
