• Verify that carpet is or will be installed (carpet will increase the temperature by three degrees).
• Add insulation between the floor joists.

• Install additional insulation to the indoor unit (glass wool insulation >13/32 inches thick).
• Install additional insulation to the refrigerant piping (insulation >13/16 inches thick).
• Seal all gaps between the indoor unit and the ceiling tiles (make the area air tight) so that humidity does not transfer from the plenum to the
conditioned space. Also, add a ceiling grille for ventilation.
