In today’s Lexington example of “the world turned upside down,” manufacturing jobs expand while financial services endures layoffs.

A Lexington company that builds large ceiling fans will invest $17.3 million to expand its headquarters and add 51 full-time jobs, officials announced Thursday.

“Big Ass Fans has become a real economic force in Lexington and the state,” said Carey Smith, president and chief executive officer of Big Ass Fans.

About 110 people work at the company’s Lexington headquarters. Average hourly wages for the new employees will be $25.27 excluding benefits.

The downside?

Chase will phase out its Lexington loan processing center by next summer and eliminate 430 jobs, the bank announced Thursday.

The decision was based on a persistent slump in new home-equity loans, which are processed at the center, said Kim Greaves, senior vice president in charge of home loan servicing for Chase.

Don’t worry. The housing slump will end… eventually.
