Should I replace my furnace and air conditioner at the same time?

People often ask us if they should replace their furnace and air conditioner at the same time. The answer is, it depends.

In about 70% of situations, it makes sense to replace your furnace at the same time as your AC unit. Here are the times in which you should seriously consider doing so:

  1. If your furnace is 10-15-years-old or older, then you should consider replacing your furnace as well. That is because the average lifespan of an air conditioner is 10-15 years, and the average life of your furnace is around 20-30 years. If your furnace is less than 10 years old, strongly consider keeping it.
  2. If you are purchasing a new, high-SEER air conditioner (above 16 SEER), then you will need a variable speed blower motor in your furnace to power the AC.
  3. Also consider replacing your furnace if your HVAC equipment is in a difficult to reach location, or if you reside far away from your local contractor.
  4. If you are retiring, or planning on doing so soon, consider replacing your furnace at the same time as your air conditioner so you won't have to worry about it when you are living on a fixed income.
Otherwise, you should put careful consideration into keeping your existing furnace...it has a lot of life left in it! For more information on this topic, try:
