The answer to 'AC or AC' is that 'AC' refers to air conditioning, while 'AC' can stand for alternating current. Air conditioning (AC) is a system that cools and dehumidifies the air in a home or building, providing comfort and improved indoor air quality. Alternating current (AC) is a type of electrical current that periodically reverses direction, in contrast to direct current (DC) which flows in a single direction.
Air conditioning systems come in various types, such as central air conditioners, window units, and ductless mini-splits. They work by removing heat and humidity from the indoor air and transferring it outside, using a refrigerant and a compressor. The benefits of air conditioning include improved comfort, better indoor air quality, and reduced humidity. Costs can vary depending on the size of the unit, its efficiency, and the complexity of the installation.
