Residential air conditioning systems are designed for cooling and dehumidifying the air in homes. These systems come in various forms,  ductless mini-split systems / wall mounted split units, and window or portable units. They work by extracting heat from indoor air and releasing it outside, thereby lowering the indoor temperature. Residential AC systems are essential for keeping homes comfortable during hot summer months and improving indoor air quality. They vary in size and efficiency, allowing homeowners to choose the best fit for their needs.
