How can you increase the efficiency of an older gas furnace?

Increasing the efficiency of an older gas furnace can effectively be achieved by enhancing insulation and sealing air leaks. Proper insulation helps to maintain the heat generated by the furnace within the living space, preventing it from escaping through walls, ceilings, or attics. When air leaks are sealed, it minimizes unwanted air infiltration, ensuring that the heated air produced by the furnace remains inside the home longer. This allows the furnace to operate more efficiently, as less energy is wasted on heating the outside air.

Increased insulation and sealing also reduce the workload on the furnace itself, promoting its longevity and reliability. This optimization of the heating system directly correlates to reduced energy bills and improved comfort levels within the home, making it a practical approach for enhancing the performance of an older gas furnace.
