They Built This House With a dual heating system So You Get Efficient Warmth Plus air conditioner
Hydronic radiant is the efficient base heat for the whole house, but on its own it can't cool — and it's slow to recover once you've turned it down. So a full HVAC system runs alongside it: air conditioning for the hot months, and a furnace that can warm the house back up in a couple of hours when you walk in from vacation, while the slab quietly catches back up to its efficient base. Two systems, each covering the other's blind spot.
