About Air Conditioning

Fortunately, there are options to cool your home that do not require a generator large enough to power the central air conditioners. You can buy portable 9000 BTU air conditioner that will cool off a 20’ x 20’ room easily. The rule of thumb if you need 20-25 BTUs per square foot. Every 10 BTUs uses one watt of power. To cool a 450 square foot room with a portable AC unit you will need 9000 BTUs and this will pull about 900 watts of power. Window and “through the wall” AC units draw the same wattage as portable AC units. If you have window or “through the wall” ac units, that are not normally used, then it is advisable to make sure they are in good working order before hurricane season. Powering a couple of high efficiency AC units will be an effective way to increase the comfort levels without guzzling all your fuel.

Note: When looking at window and wall generators, watch out for the plug types, there are generally four plug types on room air conditioners 115 volt 15 amp (115/15), 250 volt 15 amp (250/15) and 250 volt 20 amp (250/20) and 250 volt 30 amp (250/30) they all require different connectors. The 250/20 and the 250/30 are generally used on window ac units that also have heaters included, not something we need in Florida.
