Yes, it is possible to replace an air conditioning (AC) unit without replacing the furnace. The AC unit and furnace are separate components of a heating, ventilation, and air conditioning (HVAC) system. While they work together to provide both heating and cooling, they can be replaced independently of each other.
The AC unit is responsible for cooling the air, while the furnace handles heating. If you only need to replace the AC unit, you can do so without affecting the functionality of the furnace. The AC unit is typically located outside the house, while the furnace is typically located indoors.
During the replacement process, the HVAC technician will disconnect and remove the existing AC unit and install the new AC unit in its place. The furnace will remain untouched unless there are specific issues with it that require attention or replacement.
It's important to note that while you can replace the AC unit separately, it's generally recommended to consider the overall efficiency and compatibility of the HVAC system as a whole. Upgrading both the AC unit and furnace together can often provide improved energy efficiency and performance. However, if the furnace is in good working condition and meets your heating needs, it can be retained while only replacing the AC unit.
