Removing an old heat pump requires careful disconnection of refrigerant lines, electrical wiring, and any related valves. This step must comply with all local safety codes and environmental regulations, especially when recovering refrigerant to avoid harmful emissions. Licensed HVAC professionals use specialized equipment to safely handle these materials.

Placement

Proper placement of the units is essential for performance and longevity. The heat pump unit should be installed in a location with sufficient clearance for airflow and easy access for maintenance. It’s typically mounted on a level pad or brackets above ground level.

Connections

Once the units are in place, the installer connects the system components. Electrical lines are carefully run between the heat pump and the indoor unit and connected to the main power supply, typically with the addition of a disconnect box for safety. Refrigerant lines are then connected and charged to ensure proper flow between components for heating and cooling.
 
Additionally, a condensate drain line is installed on the indoor unit to carry away moisture generated during cooling. All connections must be pressure-tested and sealed to prevent leaks, and the system is inspected to ensure it meets manufacturer specifications and code requirements.

Testing and Calibration

After the heat pump installation, the technician will thoroughly test the system to ensure it is functioning properly. They will check for any refrigerant leaks, verify the airflow, and calibrate the settings to match your desired temperature preferences.

Owner Education and Maintenance

Finally, the technician will provide you with a comprehensive explanation of the installed system, its features, and how to operate it efficiently. They will also offer heat pump maintenance tips to help you keep your heat pump in optimal condition for years to come.
