Regarding heat, air is an insulator only if it is not moving and only for width of the layer up to 2 cm.
Regarding electricity, air can become a conductor if the voltage is high. It also has to do with humidity. As moisture rises, air becomes a conductor. Think of the thunder and lightning. A spark of electricity goes through the air.

True, remember lightning. Given enough potential, current will flow. Actually, the air get heated, which initiates the start of flow.
