Additionally, window air conditioning units do not have to be moved every now and then from one place to another. However, like any other air conditioning equipment, it produces sound, the intensity of which differs with the type and size of the window air conditioning unit. Constant noise can indeed be really disturbing and distressing to the household and surrounding residents.
It is, for that reason, advisable for the customer to compare window air conditioning units by inspecting the sound power level labels on the unit or in the literature specifications. The sound levels are frequently given in decibel ratings, and the greater the decibel level, the louder the unit will be. The sound pressure rises by a factor of ten for each 10-decibel increase. For example, 60 Decibels is 10 times louder than 50 Decibels and 100 times louder than 40 Decibels.
The compressor and the fan are combined into a single unit and mounted in the window air conditioning unit, and this is the source of all the noise in the air conditioner. The other causes of noise might be worn bearings, cabinet rattles, unclean or rusty fan blades, worn rubber mountings and compressor wear. Regular upkeep can decrease the noise to some extent, but with the passing of time, there is bound to be a rise in the level of the noise.
You should check whether your window air conditioning unit is vibrating or producing a rattling sound, and if so, then it is not a normal situation. The reason for this can be inappropriate installment or loose side panels. If, however, you hear a scraping sound, you should either take the help of an authorized service provider or you can also try to find the source, and fix it yourself http://www.alaskanhomeservices.com/ .
