David Aronson, the owner of Kool Kars, likes to tell people, "We cooled the Mayflower." He hasn't actually been in business quite that long, but he has been providing cooling systems and air conditioning for all types of vehicles since 1992.
Kool Kars is conveniently located off South Meadow Road, directly across from the Plymouth Municipal Airport, and offers free parking in its lot. It is very easy to get to and is just minutes from the highway.
