Can I Replace My Furnace Without Replacing My AC?

TechXpert verified by Ken Kontra

You can replace your furnace without having to replace your AC unit. While you may be considering replacing your whole HVAC system once your furnace gives out, this isn’t always the most practical solution, since each unit of the system can be replaced without significantly affecting the other.

Hold the Heat

You can save time and money by only replacing your furnace once it starts to wear out. But while it may not be necessary to replace your AC at the same time as your furnace, it’s smart to have both systems checked to see if a double replacement is the best option for your home.

Replacing both units at the same depends on certain factors, like:

The age of your units
The age of your home
Local climate conditions
Your desired HVAC features and technology

While a matched HVAC system may work more efficiently, if your current AC and a new furnace are compatible based on these factors, then you can choose to only replace your furnace and save yourself quite a bit of money.

Parts to a Whole

Your HVAC system contains separate heating and cooling units, so there’s no need to worry about one feeling left out when the other is replaced. If your AC is in great shape, it’s usually not necessary to replace it with your furnace. However, if your AC can’t handle the heat, it’s smart to consider a replacement at the same time.
