Some manufacturers, he said, don’t seem to listen much to people in the field who actually install and service the equipment. ”They have their own engineers” and are more likely to listen to them. However, according to Porter, ”the guy in the field has a better idea of what is needed in the field.” Many air conditioning dealers he knew were not satisfied with the products available. Porter said he was encouraged to try his hand at inventing by other dealers, many of whom said, ”You build a better mousetrap and we will buy it.”
One time I had a buddy with 90 “defective” boilers; this was the guy who forgot to check the gas meters. The next time he called me he had 265 defective boilers. Of course, my first question was, “Do you have gas?” After I got called some nasty names, we proceeded with the questioning. I asked him if he had 110 V to terminal L1 and L2. This is always our starting point, making sure the electricity is turned on. I got the classic answer: “How do I know, I’m only a plumber.” I asked to speak to the electrician, who confirmed that he had power to L1 and L2. I asked what the voltage was; sometimes you have lower voltage and the system won’t work. He confirmed that he had 120 V. Next, I asked him if he had continuity through the control circuit. His answer was, “I’m a union electrician, I put power to the boiler and hook up thermostats; I don’t know about boiler wiring.” It was time for a field visit.
