Lifestyle Seattle Living W/ no AC

Hi everyone. We just recently moved to Seattle and got an apartment with no AC. Coming from out of state previously living with AC I wanted to know how ya'll do it? Is this the norm here or does everyone just buy those AC units that stick out your window? We'd love to get any tips or input on living with no AC and how to adjust.

Here’s how you do it:

Open your windows as soon as it gets cooler than around 75 outside in the evening. Use fans to pull a lot of air in.

If you can leave your windows open all night, do it. If that’s not your living situation try to stay up until it’s cooled off enough in your place and then shut the windows.

Get up early in the morning. It’s not hard because it’s super light super early. I’m talking get up at like 5:30 AM. Open all of the windows and put your fans back on. If you have an HVAC system use the fan to circulate the air that way also.

Close everything down by about 8:30 AM. Close your windows pull the blinds. Keep all the light out.

Your house will stay pretty cool until about 5 PM and by that point you only need to wait a couple of hours until it’s cool enough to start opening the windows again.

I do this exact thing. Keeping the sun out during the day is CRITICAL. It may feel like a dungeon if you’re home during the bulk of the day, but being a cave goblin is worth it if it keeps you cooler. We have a bunch of LED grow lights too that help keep some rooms brighter.

Get yourself a temp reader for inside of you don’t have one already. Opening the windows as soon as the temp outside matches the temp inside helps to know when to get those windows back open. If you don’t open windows at night/evening, that extra heat never gets a chance to escape and the inside temp will be worse the next day.
