8. On August 18, 2019, Nillis replaced the HVAC (Heating, Ventilation & Air Conditioning) system in its office building. The office building was purchased in 2014 and was being depreciated over a 30 year life. The new HVAC system cost $27,000. The new system will not extend the life of the building, but it is much more efficient than the old system. In addition, the installation included new venting that will make the building's temperature much more consistent from room to room and increase employee comfort. No depreciation has been recorded on the building or the new HVAC system for 2019
