When having a new furnace installed in Paradise, the installation cost can vary based on several factors, including the kind of furnace you want, the brand, the efficiency rating, and other installation-related costs. If you're putting in a standard unit, say a gas furnace, you might anticipate shelling out somewhere in the ballpark of $3,000 to $7,000, which includes the installation. If you're going with a high-efficiency model instead or an alternative with some neat features, you could end up spending quite a bit more. Some estimates range from $5,000 to $10,000, and others seem to have no ceiling. Hearing estimates like these makes me think of my dear old dad and some of the less-than-stellar furnace salesmen he encountered in his day.
