CHARLOTTE, N.C. (AP) - An apparent problem with an air conditioning unit led to some chills for workers at a downtown Charlotte office building.
The building was briefly evacuated Tuesday after workers complained the structure was shaking.
Charlotte Fire Department Capt. Rob Brisley says the building was evacuated as a precaution, but workers were allowed back in a short time later.
Brisley says the department didn't detect any structural problems and turned the problem over the building maintenance.
Workers may have thought the building was shaking because of vibrations from a possibly faulty air conditioning unit on the roof.
