Indoor Split Heat Pump System

An Indoor Split System is a geothermal heating and cooling configuration that separates the main components of the system—placing the compressor and heat exchanger unit indoors, while pairing it with a remote air handler or furnace.

This configuration is ideal for homeowners who want to retain an existing furnace or air handler but still upgrade to the efficiency and sustainability of geothermal. The indoor split unit connects seamlessly with existing ductwork and offers flexible installation, particularly in homes with limited mechanical space or unconventional layouts.

Indoor split systems are commonly used in both retrofit and new construction projects and are especially advantageous in homes that:

• Have limited space for a packaged unit
• Already have a high-efficiency furnace or air handler installed
• Require zoning or multiple air handling units
• Need a quieter, indoor-only geothermal solution

By isolating the compressor indoors and allowing you to keep your existing equipment, an indoor split system provides both flexibility and energy savings—making it a popular choice for customized geothermal installations.
