Replacing an AC and a furnace at the same time can be costly. Yet, the only way to ensure that your air conditioner performs at its rated efficiency is by replacing your furnace simultaneously.
There’s just one problem. The average AC lifespan is about 15-20 years, whereas the average furnace lifespan is about 15-30 years. This means your furnace generally lasts longer than your AC.
In this post, we'll explain why simultaneous furnace and air conditioner replacement is perhaps the best choice. We'll also explore a few reasons why it may not be ideal to replace both systems together. Plus, we'll take a look at factors affecting furnace and air conditioner replacement costs, the process of professional services, and so on.
Wondering why simultaneous furnace and air conditioner replacement works best? Here are the three common reasons:
A furnace lasts much longer than an air conditioner. This means, if you installed a new furnace and AC together and the AC is aging, most likely you don’t really need to replace your furnace for another 5 or so years. However, if you only replaced the AC years ago, it is clearly time to replace your furnace as well.
Think of your furnace and AC as conjoined twins: each of them has their own separate compartment, but they share the indoor unit (i.e. the blower motor). If you spend extra money to upgrade your AC but leave the furnace and blower motor as is, you’re really wasting money.
This is because the AC is really only half upgraded and won’t work as efficiently as it’s designed to. So, consider upgrading the furnace as well if you’re upgrading to an AC with SEER above 16.
If you’re planning to retire soon or have a big investment in waiting, you perhaps won’t be able to afford the cost of a furnace and air conditioner in the next few years. So, it’s best to go ahead and replace both units now. This way, you can be at ease knowing that your new HVAC system will work fine for the next decade or more.
The biggest reason to not replace your furnace together with your AC is because the furnace is less than 10 years old.
Generally, if the furnace is less than a decade old, waiting until your next AC replacement is the best decision. This is because the furnace will probably last for two or three decades, whereas the AC should be replaced every 10 to 15 years or so.
The Cost of a Furnace and AC Replacement
Wondering what the average cost of furnace and air conditioner replacement is? AC and furnaces can be categorized into three groups depending on their efficiency and performance.
Here are a few factors that affect the average cost to replace furnace and AC units:
At the end of the day, the decision is yours, but we highly recommend hiring a professional furnace and AC replacement service to help you make the final choice.
A heating and cooling specialist can help you find a furnace that matches your new air conditioner, maximizing your system’s efficiency, reducing your energy bills, and extending the life of your new system.
