Heat pumps in Philadelphia area?

I am in upstate NY and not really familiar with southern PA winters. Do heat pumps with electric (or gas?) back-up work out well there?

Outside of Philly they work fine!!!Newer ones much better than the old ones.

Agreed...heat pumps are a hard sell to some here in PA, but they do very well here.

A dual fuel would do you well.
