Typically, the answer is always yes, especially if it is a question between replacement or repair due to a breakdown. Older furnaces often operate below 80% efficiency while new models run at 95%+ efficiency, saving energy and qualifying for rebates to reduce the upfront installation cost.

Most furnaces last 15–20 years. Replacement should be considered if you are faced with a large repair bill due to a breakdown, to take advantage of temporary rebates which can significantly reduce the cost of a new furnace installation, or if it is no longer providing consistent heating for your home.
