Your heating system is usually the largest energy user in your home, so choosing an energy-efficient unit is especially important. When shopping for a new gas heating system, compare efficiencies and installation costs of various models. The Federal Energy Agency requires all furnaces to be given an annual fuel utilization efficiency (AFUE), which tells how much heat the system extracts from the fuel it burns during a single heating season. The higher the AFUE, the more efficient the system. Download this guide to learn more about home heating systems.
