The answer to 'what does AC do' is that an air conditioning (AC) system cools and dehumidifies the air in your home. AC systems work by transferring heat from the inside air to the outside, using a refrigerant to absorb heat and a compressor to circulate the refrigerant. This process lowers the temperature and removes moisture from the indoor air, providing a comfortable, cool, and dry environment.
AC systems also help improve indoor air quality by filtering out dust, pollen, and other airborne particles. They can also help control humidity levels, which is important for preventing mold and mildew growth. Proper maintenance and regular servicing of your AC system is essential to ensure it continues to operate efficiently and effectively.
