Benets
• Indoor comfort during warm weather — Centralairconditioninghelpskeepyourhomecoolandreduceshumiditylevels.
• Cleaner air — Asyourcentral air conditioningsystem draws air outof variousroomsinthe housethroughreturnairducts,
the air is pulled through an air lter, which removes airborne particles such as dust and lint. Sophisticated lters may
removemicroscopicpollutants,aswell.Thelteredairisthenroutedtoair-supplyductworkthatcarriesitbacktorooms.
• Quieter operation — Because the compressor-bearing unit is located outside the home, the indoor noise level from its
operationismuchlowerthanthatofafree-standingairconditioningunit.
