The Community Energy Project is a great organization that has the most up to date information about heating and cooling your home in the most energy efficient and cost-effective way.
Give them a call and are able to provide great information over the phone. Additionally, in some cases (I'm not sure what their requirements are) they will send someone out to look at your place and make suggestions as to the best set up to use for your property. Additionally, they often have discounts and financing programs available only through them!
