First of all, you can't count on door hangers as a primary source of advertising. Secondly and secondary it will help generate top of mind awareness to the prospective customer. My technicians place these on doors of 4 homes that surround the customer we are working. We have had a few calls, but not alot to write home about. But everytime we go back to that same house we remind all the neighbors that we were there. Each time we do this our odds get better that when the neighbor needs work, he/she will call us.
AS for cost to perform, it is alomost free advertising.
