Why Is It Always Hot Upstairs, Even With an AC?

There are a few reasons for why your upstairs is too hot in summer, even with air conditioning.

Reason #1. Heat rises — it's the law of physics. So, the upper levels of your house are going to be warmer than the lower levels.

Reason #2. Most houses are not built with upstairs cooling in mind. This means that there isn't much insulation or ventilation upstairs, which makes it harder to keep cool.

Reason #3. Hot roof. In the summer, your roof can get very hot, and this heat will radiate down into your upstairs room. This is especially true if your roof is dark-colored.

Reason #4. Your AC is not properly sized. This is a common problem. If your AC unit or your HVAC is too small, or offers less BTUs than your place needs, it won't be able to effectively cool your entire house (or the rooms you are targeting), and the upstairs will be warmer than the downstairs.

How to Keep the Upstairs Cool Without an AC

There are a few ways to keep upstairs cool in summer without an AC — inexpensive, available to most of us and efficient. Here are some of our favorites:

1. Use an evaporative air cooler. Air coolers by Evapolar are an excellent option to have at home — you can stay cool in any room, and you can easily carry them to the hottest part of your house, upstairs or anywhere else. They are very energy-saving as well! Excellent tip on how to make your upstairs cooler in summer.

2. Install a ceiling fan. A ceiling fan can help circulate the air and cool down the room. When it's really hot, all that fans do is just move the hot air around but it's better than nothing — they help with ventilation and remove the stale air.

3. Use window fans. If you have more than one window upstairs, this is a very working option for ventilation and cooling. Window fans can be installed in windows on the opposite sides of the room to create a cross-breeze.

4. Plant trees or shrubs near your house. This will provide shade and keep your house cooler in the summertime. If you have several floors in your house, the shadow might take some time while the trees are growing.

5. Purchase a roof insulation kit. This is a great way to keep the heat out of your upstairs rooms, and it's not too expensive either!

6. Hang a reflective window film on your windows. Reflective window film can help keep the heat out of your upstairs rooms and save you some money on your electric bill!


7. Open the windows. This will allow cooler air to flow into the room — make sure you make the best of the coolest parts of the day and aerate as much as you can.

8. Close the curtains or blinds. This will help keep the heat out and the cool air in.

9. Add attic insulation. This one of very efficient ways to cool upstairs room and make your house more energy-efficient.

10. Paint your ceiling white. Little lifehack, with a minimalist touch — the white color reflects the heat and keeps your upstairs room cooler.
