What is InterNACHI's estimation for the life expectancy of a standard gas oven?

InterNACHI estimates the life expectancy of a standard gas oven to range from 10 to 18 years. This estimation is based on typical usage patterns, wear and tear over time, and the materials used in the manufacturing of these appliances. Gas ovens have components that can be affected by heat exposure, corrosion, and general wear, which are factors that contribute to their lifespan.

While some appliances may last longer due to less frequent use or higher quality manufacturing, the general range provided by InterNACHI offers a realistic view for average consumers, ensuring they understand when they might need to consider a replacement. Other ranges provided in the choices, such as 5 to 10 years, 18 to 25 years, and 25 to 30 years, do not align with typical consumer experiences or industry standards for gas ovens.
