You say that both the HW tank and HVAC air handler are in the basement.
What provision was made for the HW tank leaking and the condensate "drip"
from the AC. *Surely there is some sort of drain there ?

Around here, NJ, new construction, in a basement the condensate is
normally handled by a small pump taking it outside. The water heater
TPV valve is plumbed with a pipe to a few inches of the floor. No
basement floor drain required by code and rarely are they found. I
think floor drains introduce as many problems as they solve, ie
[potential backflow issues.

The houses do have sump pump pits, but the builder usually only
includes the actual pump if there is groundwater so that it is
required.
