I have a great relationship with all of the guys in my area. I always try to help them out, and they help me. I have a relative who has been in business for 40 years like myself. Both of our fathers were in appliance repair, and we used to all help each other out. Him and me talk daily at least 10 times a day. Talk about calls, where were're going. Bad service calls, good service calls, etc.
I have one tech who doesn't like to work on dishwashers, gives me referrals or my relative. Another one doesn't like to work on new whirlpool washers, so gives calls to me. I get coin op and commercial calls from most of techs in my area and parts store. I give calls to others when I don't want to drive to certain areas that are far. It helps, believe me.
Believe me, it's better to have a good relationship with other techs than adversarial. Only one recently that was a jerk was a sears tech. Was at parts counter, and I asked him a question about a a test code for a kenmore oven that didn't have a tech sheet. Kept telling me "I don't know". Wouldn't give me any info. I guess he thought he was protecting his job. But I feel differently, I like to help people and have a good repor with 10 good techs in our area.
