Benefits of Replacing AC and Furnace At The Same Time

October 23, 2025
Replacing AC and Furnace At The Same Time

Heating and cooling your home are important factors in maintaining a comfortable home environment. There will come a time when you will have to replace your heating or cooling system due to old age, issues beyond repair, or inefficiency. You may want to replace only one system, since replacing your air conditioner and furnace at the same time is a costly investment. However, you want to replace both at the same time if the furnace is older than 15 years, and if you are purchasing a higher efficiency AC. Furthermore, replacing both systems at the same time can lead to more efficient heating and cooling of your home that will save you money on your monthly bills. Below we discuss some of the benefits to replacing both at the same time.

Save Money

One major reason for replacing both your AC and furnace at the same is the lower installation costs resulting in money saved.  If you replace the AC and furnace separately, then you will have to pay labor costs twice. Having units of the same age can also help with repairs and maintenance visits, and both be under warranty unlike if they were mismatched. However, most of the savings will come from improved efficiency with a matched system.

Improved Efficiency

If both your air conditioner and furnace are giving you issues, they may be on their way out. Though failing units may be inconvenient it can provide the opportunity to upgrade both systems to more modern and efficient units. When both units are replaced at the same you can switch between the two systems without losing efficiency. New systems allow for improved performance and trying to mix older systems with new ones can lead to undue stress on the system and cause it to fail.

Improved Lifespan

A properly matched system means reduced strain on your furnace and air conditioner which leads to an improved lifespan overall. Not only will a matched compatible system increase the lifespan, it will also help increase the efficiency of the system and comfort level in your home.

However, there is a time when its best not to replace both at the same time. If your furnace is less than 10 years old it will most likely last until the next time your air conditioner needs to be replaced.
