It helps to inspect the data structures.

Try:

specials = %w( of or w AC ).
inject({}){|h,s| h.update({s.downcase,s}) }

p specials

text = DATA.read.downcase
p text.split( /([^a-z]+)/ )
puts text.split( /([^a-z]+)/ ).map{|s|
  specials[s] or s.capitalize }.join

__END__
ADDITIONAL SPA  (ONLY AVAILABLE W/PURCHASE OF POOL OR SPA)
SELLER HEAT/AC/DUCTWORK
