If a furnace is over 15 years old and efficient, what should you do?

Considering the efficiency and age of the furnace is crucial for making informed decisions about heating systems. Checking the Annual Fuel Utilization Efficiency (AFUE) rating provides valuable insight into how effectively the furnace converts fuel into heat. An older furnace, even if it is still operational, may not be as efficient as newer models that incorporate advanced technology, which could lead to significant energy savings over time.

Understanding the AFUE rating helps in comparing the current furnace's efficiency against newer models. If the AFUE rating is low, it may indicate that the furnace is wasting energy, thereby increasing utility costs and impacting overall efficiency. By gaining this perspective, you can make a more informed decision about whether to continue using the furnace, upgrade to a more efficient model, or budget for future replacements.

This approach emphasizes a proactive stance on energy efficiency and long-term savings while also considering the current operation of the furnace.
