Repair appliance or replace?

[Sean Kuhn]

When do you guys know when to repair an appliance, or replace it. My appliance guy is a minimum 65 per visit. Most guys do this. My theory is I take the original price of the appliance, divide it by the number of years I've had it. A/B=C If the cost to repair the appliance is greater than C, I replace the appliance. If its less than C, I repair it. What do you think?
