technically, it can
. But without it, your heat pump will not deliver warm or cool air into your home—so running your heat pump is pointless. Running a heat pump without Freon can also damage essential components and potentially ruin the system altogether.

a lack of refrigerant will hinder the evaporator coil's ability to absorb heat
. This hindered ability to absorb heat causes the moisture on the evaporator coil to freeze.
Do heating systems use Freon?
The earliest systems used chemicals that were either toxic or flammable, but
modern heat pumps use safe blends referred to by the general name “Freon”
(a trademark of DuPont). The main blend used today is R410A and is replacing an earlier blend, R22.
