- Four (4) HVAC mini splits at the Kessler 4-plex housing area (one per housing unit)

- One (1) HVAC mini split at the Rocking L house.

- One (1) HVAC mini split at the Hole in the Wall Visitor Center.

Each of the buildings is equipped with 240 volts / 100-amp electrical service. New branch circuits will need to be installed for the new HVAC units.
