One System. Heat In Winter, Cool In Summer.
Modern cold-climate heat pumps deliver 100% of rated heat down to 17°F and keep running below zero — no gas line, no combustion, and up to 3× more efficient than a furnace.
One refrigerant loop. Reversible.
A heat pump doesn't create heat — it moves it. That's why it's up to 300% efficient (a furnace tops out at 98%).
Summer Cooling
Refrigerant absorbs heat from indoor air and dumps it outside — identical to a standard AC.
Winter Heating
The refrigerant cycle reverses. The outdoor coil now absorbs heat from cold outdoor air and moves it inside.
They actually work in Philly winters.
"Heat pumps don't work when it's cold" was true in 2005. Today's inverter-driven cold-climate models are rated for continuous operation well below Philadelphia's coldest recorded temperature.
Cold-climate models maintain full heating output down to 17°F.
Continues heating in Philadelphia's worst polar vortex days.
Higher HSPF2 = more heat per kWh consumed.
Automatic. Backup heat kicks in during defrost.
