One of the key aspects to consider is whether to repair or replace your furnace. Furnaces are typically made to last 15 to 30 years. It could be time to start looking for a replacement if your furnace is more than 15 years old. Although many furnaces can live up to 30 years, this usually happens after they have endured numerous repairs.
Remember, there are various techniques to lengthen the lifespan of your furnace. Routine servicing is a simple and reasonably priced strategy to extend the life of your furnace. You should change any dirty filters to keep your furnace from working too hard.
