Heat loss in attic

I have a two story house with vaulted ceillings on both ends. The roof will have frost were the vaulted ceillings are, but little to no frost over the attic area. Snow also melts quickly from this area, I have a heat pump with ducts in the attic and fiberglass insolation in the ceilling. Any idea were all the heat loss may be coming from. Is it being lost back thru the ducts? Is there any way to test it to find were the loss is?

More than likely your ducts and/or the openings for your registers are leaking air. For the ducts the standard test is known as a "Duct Blaster" and for the registers registers and/or recessed lights the standard test is known as a "Pan Test". this can be done by an "Air Sealing" company and some HVAC companies too. However, you do have to ask first if they can perform those tests.
