There are sometimes circumstances where the installation cost of a high-efficiency furnace is quite high – mostly for semi-detached homes with finished basements and much increased ventilation costs- and it might actually be more feasible to replace your old furnace with a mid-efficiency furnace model.
With the rebates also on the downfall, Mid-efficiency furnaces may be the most cost-effective solution for smaller attached homes, especially where the cost of installing a high-efficiency furnace is considerably higher and more difficult.
