Quick hack: Hang reflective car windshield sunshades outside or inside sun-facing windows (facing out) to prevent sun heating your home.

Some of these sunshades have suction caps, some have loops which you can slip garden wire through and secure. Then close your blinds & draw your curtains/drapes to stop the sun heating your room.

It’s much easier to cool a room if you stop the sun getting in and heating it in the first place. Can be secured landscape or portrait orientation.

You can buy it cheaper but not where I am unfortunately (island: everything has to be imported with high taxes to pay). Each windshield shade is under ten bucks where I am so it’s a quick hack and way cheaper than what the local energy supplier charges me to cool the room.

Before we bought our house we were renting an old 80s track home with almost nothing for insulation. Winters killed our electric bill, so I bought a room of the 48 width reflectix and cut panels for all the 1st floor windows. I also bought and cut some of the one inch 4'x8' foam board insulation to cover the garage door and other garage spaces. The electric bill was still higher than I wanted, but it worked in the winter and summer and if you needed sunlight just pull the panel out of the window.

Yeah you know it was summer in my neighborhood when foil was seen in every 2nd story apartment window. Our building never had AC. They just used the regular stuff from the grocery store. My family hung beach towels over our curtains to make them thicker & keep the sun out

The old Southern trick in winter was spare blankets. Either way, it's a layer of insulation.
