You have to be well versed in "selling" the work to the warranty company or the customer gets killed. They will refuse work if you say ONE work incorrectly.

I have already done a dozen or so evap cores this year. The average cost is greater than 2,5oo dollars. Most of my customers have the warranty and they get out for 400...
