Split system air conditioners boast essential features for efficient cooling. They consist of two main units: an indoor unit with an evaporator coil and fan, and an outdoor unit housing the condenser coil and compressor. Refrigerant lines connect both units, circulating the cooling agent that absorbs indoor heat and releases it outside. With remote control functionality, you can easily adjust temperature settings, fan speed, and operating modes. Some models offer energy-saving options and the ability to create cooling zones. Split system air conditioners are renowned for their quiet operation and often come with air filters to improve indoor air quality.
