Save Money by Replacing Your Furnace!

If your heating equipment is older, you may actually save money by installing a new high-efficiency furnace. Modern furnaces are more environmentally responsible and boost comfort by producing heat more steadily than older furnaces. If you upgrade to a new furnace, today’s more efficient gas systems can save you around $17 for every $100 spent on fuel. A gas furnace manufactured in the early 1970’s averages an AFUE of around 65%. Today, the lowest efficiency permitted by law for new gas furnaces is 78%, and some top manufacturers offer units with 98%, near-total efficiency.
