What age is recommended for considering a gas furnace replacement?

The recommendation to consider a gas furnace replacement at around 15 years of age is rooted in the average lifespan and efficiency of gas furnaces. Typically, gas furnaces last between 15 to 30 years, but as they reach the 15-year mark, they may start showing signs of decreased efficiency, higher energy bills, and increased repair costs.

At this age, a furnace is more likely to encounter issues due to wear and tear, and newer models often offer enhanced technology and improved efficiencies, which can lead to significant savings over time. Additionally, advancements in safety features and environmental regulations can make newer units more desirable from both a safety and ecological standpoint. Therefore, the 15-year guideline serves as a practical benchmark for homeowners to assess their heating system's performance and consider a replacement to ensure reliability and efficiency in heating.
