A spa system includes a tub supported by a chassis, an enclosed space formed between the tub and the chassis, first and second vents through the chassis leading to the enclosed space, water heating and cooling devices coupled in series to a circulating system adapted to withdraw and return water relative to the tub, and a thermostat operatively coupled to the heating and cooling devices. The cooling device incorporates a fan operative for drawing air into the enclosed space through the first vent in response to activation of the cooling device, and a blower is operative for expelling air from the enclosed space through the second vent currently with the operation of the fan of the cooling device.
