I live in a 250 year old home sans central air. This past week when my husband lugged the window units into my daugthers’ rooms and their once perfectly pitched black rooms became sun filled, I was determined to find a solution. 15 minutes, one roll of packing tape, and one $5.97 redi-shade blackout blind later their rooms are back to their cave like state. I simply cut 18 inches from the bottom of the shade and then cut it in half to divide it into two sections (one for each side of the AC). I made sure that they were taller than the actual air conditioner so that they would over lap a bit when the main shade came down. I taped these side peices with the “accordions” in the vertical direction to both the window frame and the air conditioner. I was careful to use as little tape as possible on the frame as I do not want to mess up the paint! I then took the top portion of the blind, cut it to fit my window, stuck it up using the self adhesive, and voila – a perfectly dark window with air conditioning unit! Best of all when the main shade is clipped up you can not see it at all. I also have vinyl pull down shades that typically go under my fabric black out curtains which I will pull down too over the top black out shade to the top of the AC unit (yes, I am obsessed with a dark room!). Also, please note the pink card tape on one side as a flap that goes over the LED lit control panel. Those little lights can reek havoc too and it is a good practice to cover up any in bedrooms rooms. Happy Summer everyone and stay cool!
