A heater will keep you warm on those cool days. If you need to get some relief from the heat and humidity add a fan. Some of the units are portable and others can be mounted. Most of these fans and or heaters run off your golf cart battery. The hook ups are easy. Some have sensors to shut down the unit when exiting your cart. We carry the Climate Caddy, Maradyne Fan, and the Breezeasy. Control the climate in your golf cart by adding a cooling fan or installing a heater.
