So, would you charge a customer if you did not repair their sprinkler system? Well, apparently some companies do. I turned on a system this morning for a homeowner. He had another "service" tech out a few days earlier trying to get his timer to work. He has a hunter pro c. I guess the "tech" plugged in the timer and the display read "no a/c". Well the guy doesn't even test the transformer output for voltage or the 110 outlet. He calls his boss. Tech then tells customer the transformer is out, not sure if one is available, but a new timer will cost 200 to 300 installed! Well, I go out, plug in timer and sure enough display reads "no a/c". So, I wait about half a second and sure enough display shows current time! Yep, a little patience for the timer to run thru its paces and sure enough it works. Heck, the other guy didn't even bother to turn the water on for the system. He just collected his 50 service call fee and was on his way. So heres my question.............Would you charge a customer a service call when you are unable to fix their problem?
