My home needs a new gas furnace. We plan to stay in this home for approximately 7 more years. Is it worth spending more on a Trane or Lennox furnace or would I be better off saving the extra money and getting a Goodman or Rheem furnace? The Goodman is considerably cheaper, but I have heard mixed reviews. However, if it will last 7 years then I don't see why not to get it and save the extra cash. Any thoughts?
