Tips For Finding The Right Window Air Conditioner For A Master Bedroom With Small Bathroom

Air conditioning is more of a necessity than a luxury during the hot summer months. If your home lacks central air conditioning, or has a less than effective unit, then you might be shopping for some window air conditioners soon. The sizing of window units is based on the square footage of the room which seems easy enough. But that calculation and proper installation gets a bit more complicated when dealing with a master bedroom and a small attached bathroom.

Add the BTUs and then Round Up

Air conditioner output is measured in British Thermal Units, or BTUs. You usually want to measure your square footage then multiply that number by 20 to find the minimum number of BTUs you need for a given room. When you're dealing with a main room and an attached room, you need to start by adding the square footage of the rooms together then doing the multiplying. Then round up to the next strongest unit.

Why round up? It's doubtful that your rooms lead straight into each other perfectly. So there are going to be some corners and turns to navigate. Window units don't swivel so you need more output in order to compensate for those additional architectural elements that might not be found in a standard room such as a living room or kitchen.

Consider whether You Need Two Units

If your attached bathroom has a shower, the warm humid air is supposed to be whisked out by the exhaust fan. But that method isn't always effective particularly during the warm summer months. You can counteract this added heat by placing the bedroom air conditioner in a window directly across from the bathroom so that extra air will end up in that room when the door is open.

But if you don't have a window across from the bathroom, you might need to buy a smaller secondary unit to perch in the bathroom window. Use the BTUs calculation to find the minimum air conditioning strength needed. You might want to turn the unit on only after a hot shower to keep from freezing yourself when you're going in for that shower. Only running the unit occasionally will save on utility costs and might help you run the bedroom unit less often. You can always supplement the units with light-blocking curtains and overhead fans to make smaller units more productive.
