Yes, it is possible to replace an air conditioning (AC) unit without replacing the furnace. In many HVAC systems, the furnace and AC unit are separate components that work together to provide heating and cooling.
When replacing the AC unit alone, you will need to disconnect the existing AC unit from the electrical supply, refrigerant lines, and any ductwork connections. The new AC unit can then be installed in its place, connecting it to the existing electrical supply, refrigerant lines, and ductwork.
However, it's important to note that the compatibility between the new AC unit and the existing furnace should be considered. The furnace and AC unit should be compatible in terms of capacity, airflow, and control systems. It's advisable to consult with a professional HVAC technician to ensure that the new AC unit is compatible with the existing furnace and to properly handle the installation process.
Additionally, local building codes and regulations may require certain qualifications or permits for HVAC installations. It's recommended to check with your local authorities or hire a licensed professional to ensure the installation is done correctly and complies with all applicable regulations.
