I have an 1100sq ft house in a mild climate, Oregon. The house was build in 1974 and has the original electric furnace. Gas is not available on my street so electric is my only option. I wanted to upgrade the furnace to something newer and more efficient. I have gotten a couple quotes from local companies and they have no interest in selling me a new furnace. They both said that something new wouldn't be any more efficient than what I have now. They both are trying to sell me a heat pump system. I understand the benefits to this but I have trouble believing that electric furnaces of today are not more efficient than the 38 year old one that I have. Please advise, I am so confused.
