Climate control in a car is the system that keeps the temperature inside the car even and comfortable. This includes the car's heating and cooling systems as well as their controls.
Modern automobiles use computers to provide exacting climate control. A combination of heating and air conditioning are standard in most vehicles for temperature control. Fan speed and air circulation are also controlled through the climate control system. High-end vehicles feature extra climate control components, such as humidity controls and clean-air systems with integrated high-efficiency air filters and ionizing air cleaners. Car climate control systems require regular maintenance to function properly. The first car climate control was a heater invented by Thomas Ahearn in 1890.
