Interestingly enough a big AC may not be your ideal answer to the summer heat. It might, in fact, provide you less cooling than a smaller unit, since smaller units run longer than bigger ones which tend to click on and off. Running longer permits smaller units to maintain a regular room temperature, remove moisture from the room (thereby getting rid of humidity) and ultimately gives you greater comfort. Even you are selecting a machine for central air-conditioning size is of considerable importance. This sizing however needs to be done by a pro. When dealing with a central air-conditioning system for your home make sure that the fan shuts off along with the compressor, that is, do not make the central fan for circulate the cool air, use circulating fans for each room instead.
Following are a few cooling tips which will save your air conditioning systems from breaking out in a sweat
