Theory is that a house with underfloor heating shouldn't be cleaner per se but there is less dust moving around. Dust lying still in a corner is not causing allergies, but when it moves around, it will.
I have no idea how well underfloor cooling works, so far I know noone who has it. It was first put in in more expensive apartment buildings using a geothermical form of heatpump. But nowadays you see it more and more appear in ads for the middle market segment. The temperature difference is likely not very big, but don't know any details of these systems.
