Do you use your air conditioning as efficiently as possible? Check out these great ideas window ac units to keep you cool while saving energy and money this summer! Few things are more frustrating than unpleasant heat, especially when this heat is wet and moldy. It is even worse when you turn to your air conditioner for delivery, only to find that it doesn’t help all that much. Or maybe it helps, but you crawl in anticipation of the energy bill.
The first, and perhaps worst, mistake you could make is before you even turn on your AC for the first time. All AC window units are designed with a certain amount of “airspace” in mind, and your unit may not be effective if your room is too large or too small.
All window units have a British thermal unit (BTU) rating, typically in the order of 5,000 to 15,000. The most common rule of thumb is that each square foot of space requires 20 BTUs plus 600 BTUs for each person who regularly occupies the room. It may be necessary to increase it by up to 10 percent if the room has high ceilings, gets a lot of sunlight, etc.
