Furnaces generally have a lifespan of about 15-30 years. Of course, this will vary with each system. If your furnace has been professionally maintained, it is much more likely to last longer.

When Should I Replace My Furnace?

When a furnace is breaking down regularly, it may be time to do a little cost-benefit analysis. Does it cost you more to keep your old furnace running than it would be to buy a new furnace? If breakdowns are becoming a regular part of your furnace’s life, it may be time to replace it. An old and inefficient furnace may also be raising your heating bills. Compare your current bill to one from this same time last year. Do you notice a difference? Increased energy bills and frequent furnace repairs can mean your furnace is nearing the end of its life. 

Should I Fix or Replace?

In some cases, it will be more beneficial to fix your furnace rather than replacing it. Your furnaces’ age is a significant factor to consider.  As mentioned, most furnaces last approximately 15-30 years. If your furnace is beyond three-quarters of its life expectancy and repairs are frequent or costly—it is likely more efficient to replace it. 

Do I Need to Replace My Furnace and Air Conditioner at the Same Time?

The short answer is—maybe. It depends on what kind of system you have. Indoor and outdoor air conditioning units differ. But no matter the type of system you have, there are many benefits to replacing the furnace and air conditioner together. 

Both your air conditioner and furnace use the same blower or fan to pump air through your house. The blower is necessary for both the air conditioner and furnace to produce proper airflow for the heat exchanger and evaporator coil. Replacing your furnace and air conditioner together will make installation easier and increase your system’s efficiency. 

What Should I Look for in a New Furnace?

When looking for a new furnace, be sure to consider the annual fuel utilization efficiency—or the AFUE. This efficiency rating determines how well the furnace converts fuel into heat. Look for a rating between 85% and 95% to ensure that you have a cost-efficient unit. 

How Much Does It Cost to Replace a Furnace?

The price of a new furnace will vary. According to thumbtack.com, the national average for replacing a furnace ranges from $2,000 to $6,000. The price is based on the cost of the furnace and the labor needed to install it. There are three different types of furnaces—electric, gas, and oil.
