What Kade is checking here isn’t the part most people notice.
But it is the part they feel later.
Airflow.
Placement.
Balance.
How the system will work once the family is actually living with it.
Most of what makes a system work well happens before anyone starts changing the temperature.
That’s the difference between:
“It turns on.”
And:
“It feels right.”
Mid-winter is when that difference shows up.
