Air conditioners work by removing heat and humidity from inside your home and transferring it outside, leaving the air cooler and more comfortable. The system pulls warm indoor air through a filter and over cold coils filled with refrigerant, which absorbs the heat. A fan then blows the cooled air back into the room while the unwanted heat is carried outside through the outdoor unit. Modern air conditioning systems also help improve air quality, reduce humidity, and maintain a consistent indoor temperature for year-round comfort.
