Converting from oil to gas heating can potentially increase a home's value, although the impact on value can vary depending on factors such as the local real estate market, the cost of energy in the area, and the specific preferences of potential buyers. Gas heating is often considered more efficient, convenient, and environmentally friendly compared to oil heating, which can make a home more attractive to potential buyers. Additionally, homes with gas heating might have lower operating costs, which can be an appealing feature for prospective homeowners. However, the increase in value might not always be significant and should be considered alongside other factors that influence a home's market value.
