At the present moment, there are three different types of systems that we can utilize. One is our air-source heat pumps that we can utilize. Another is a water-source heat pump where we can draw energy from the ground. And third is our ductless independent head-mounted units that we can place in many different locations throughout the home.

This arrangement provides a clear and concise explanation of the different types of systems available for utilization. Let me know if you need any further adjustments!
