Best Way to Heat a Split-Level Home
You live in  a state that's cold and has high electric rates, and electric baseboard heating uses a lot of juice. I'm guessing costs are your primary motivation, right?

If so, my recommendation would be to take the money you would spend on a whole new system (I'm guessing it would run $10,000-20,000) and instead buy a gigantic solar array capable of making your house net zero. New York state has a lot of incentives and subsidies, to say nothing of the 30% federal tax credit.

This approach will result in no disruption to the interior of your home, reduce your electric bill to zero forever, and be good for the environment. Depending on your current bill and the price of the array, this may be a financial no-brainer. Talk to some solar companies.
