Who makes Frigidaire? Does anyone have any experience with it? I'm checking out Frigidaire because a local contractor that I trust and has very competitive prices is recommending it. I'm looking into a dual fuel source with an 80% gas furnace and a 13 SEER heat pump. I live on Signal Mountain, TN (SE Tennessee) and our climate is fairly moderate. Our natural gas prices are rising rapidly and our electric rates are about the best in the country. I do want to stick with gas as a backup source since we often have localize power outages on the mountain and a portable generator can keep the house heated. Any thoughts?
