HVAC contractors looking for a humorous way to highlight a company newsletter or mass mailing can use an HVAC cartoon to send the message.

A Web site hosted by cartoonist Theresa McKracken (www.pioneer.net/~mchumor/) offers several samples of HVAC humor available and she can also customize the cartoon per each individual contractor's needs.

For more information, visit the Web site or e-mail McKracken at mchumor@pioneer.net.
