Here are some points to consider:
In Southern California, we often do not use our furnaces enough to recover the added expenses of a high-efficiency model through energy savings.
High-efficiency furnaces have a smaller carbon footprint. They use more of the produced heating energy to heat the home, and less heat leaves through the flue. However, when we consider the externalized carbon footprint from higher upfront cost, maintenance, repairs, etc., the carbon footprint argument may not hold. In Southern California, we usually recommend an 80% efficient furnace to strike a good balance between total cost & efficiency.
High-efficiency systems often qualify for significant rebates, making them financially more attractive.
For a ‘greener’ alternative, consider a heat pump system.
