2003 Chrysler Sebring Antifreeze smell

I have a 2003 Chrysler Sebring. We noticed that there was a smell of antifreeze when we would get out of the car. We replaced the top and bottom radiator hoses because the original clamps had obviously gone bad, and we thought that would fix the problem. But now the smell is getting stronger. There's no leak we can find, and there are never any puddles under the car, also when we check the level it's always the same and the temperature has never spiked over it's normal running temperature. The only odd thing I have noticed is that sometimes the heater only blows cold air, but then if I turn it off and back on again a few times it blows hot. I would really appreciate you insight. Thank you very much for your time.
