The Chico (California) Unified School District is replacing 105 HVAC systems at five different locations, including Chico High.
KNVN-TV reports that the district has needed to replace the systems because of their age, and federal funding to pay for the upgrades is set to expire this year.
The Chico district is funding the project using Covid relief funds. The money has to to be used before September 30.
Recent surveys of community members identified working and efficient HVAC systems in schools as a top priority.
Joe Morris, Chico's director of operations and maintenance, said the new systems will be more energy-efficient than the older ones.
