heat elements don't cut on enough to kill the whatever it is that causes

I'm in North Carolina so the weather is relatively mild. I would like to
switch to a heat pump. According to http://hes.lbl.gov/hes/about.html, I
could conservatively save about $1600/year on heating alone. I was as
thorough as possible when completing the survey. Last year my hvac guy, a
friend of the family, told me I wouldn't recoup the cost of replacing the
propane but I'm spending thousands each winter on propane. My propane
company has kept the price right at the break even point with electric, or
a little higher when it gets cold. The central unit is 7-8 years old,
propane heat/electric ac.

I'm going to sit down and discuss this with him next week. What are my
concerns and what questions should I ask?
