It depends on how old your furnace is and the cost to get a new furnace. A good rule of thumb is, no matter the age of the furnace, if the cost to repair is 50% of the cost of a new furnace, you should replace it. But for less expensive repairs, you should be less resistant to replacing the furnace the older it is. So if the furnace is 20 years old, and the cost to repair the furnace is only 10% of the cost of a new furnace, you should probably replace it (because itâs more likely to break down again soon).
If your furnace were old and worn out, your decision would be easyâbuy a more efficient modelâbut the average life of a well-maintained furnace is 25 years, so yours still has plenty of life in it. If you did replace your furnace with a 97 percent efficient system, you'd cut your heating bills around 20 percent.
