Summer in central Ohio often brings a combination of high temperatures and intense humidity that can make the interior of a parked vehicle feel like an oven. When the sun beats down on the asphalt near High Street, cabin temperatures in a luxury sedan or SUV can climb well past 100 degrees in a matter of minutes. While standard air conditioning systems are designed to lower the ambient air temperature, they often struggle to address the heat trapped between your body and the premium upholstery.
