They had a highly compensated and motivated sales force (including my older brother). I don't remember the name of the outfit, but he worked for them for around 10 years. They used to send 5 or 6 of the best sales guys on trips and cuises every year, plus lots of bonuses and so forth. Those guys were out there cold selling solar systems, pool heater systems, and later on and this is where it got quite funky - electrical repair work. And in my opinion, not one person in that outfit was qualified in any way, shape. or form to sell or do any electrical repairs But they had a mountain of tricks for getting a sale out of Joe the Homeowner, including the old "We are providing "free" fire extinguishers to all those who use our services this month.
