The Klamath Falls City School District is undergoing a heating, ventilation, and air conditioning (HVAC) replacement project at four of its schools over the next two years. Pelican Elementary and Roosevelt Elementary are planned to be renovated first, with Mills Elementary and Conger Elementary to follow. The schools are currently heated with geothermal, steam and diesel boilers. All the heating systems have reached the end of their expected equipment lifespan and are due for replacement. Additional upgrades are planned to upgrade the lighting and renovate the bathrooms.
