A lot of the guys got out of the repair end of things. The supply house sells them and hands off the repair referrals to me. The repair end of things leads to other work too. Went to what was thought to be a generator problem, turned into all day rodent chewed wiring repair on overtime.
Go to some of the local sales gatherings that Generac puts on from time to time. Speak to the other guys who just do sales only. Networking.
I got into the service side because I didn't like sending work to others either. Thing is, you are either in or out. Takes a financial commitment to be in it, classes, parts kits. Need to be doing it regularly to keep the skills sharp and to make some of that money back. Some guys just want the installs, that's fine too. I do more service than installs.
