Full Load vs. Partial Load: What’s the difference?

Full-load—or whole-home—

heat pumps will do all
of the heating and cooling in the home or building.
For replacement situations, your existing heating-
and-cooling systems are no longer required.
Full Load

Responsible for 90-120% of the
heating load

In partial-load applications,

your new heat pump
will supplement your existing heating system, as
well as cool your home during the warmer months.
Partial Load

Responsible for less than 90% of the
heating load
