Steve Ottley of Clark & Rush said he and his partner were conducting an HVAC installation in September at the home in Sacramento when they stumbled upon 12 baby food jars filled with gold dust, KOVR-TV, Sacramento, reported Thursday.
"I still can't believe it today," Ottley said of the discovery. "It's unreal. We kind of just looked at each other and said 'wow'.'"
The gold was given to the homeowners, who asked that their names not be reported.
Clark & Rush said workers conducting an installation in the 1980s discovered about $25,000 worth of gold coins in a home.
