Pat: Don't fool yourself cigarette smoke was not the only thing you were cleaning. Grease from cooking and fine dust among other things mix to look like that, outdoor car exhaust and other pollutants all mix to cause the buildup. If your house has blown in insulation, it degrades over time and deteriorates into dust which is picked up by the output cooled air ducting. Small leaks in the ducting will pull it right into the cool air being circulated into you system.
That is the major reason for fires in heating systems and why air conditioning people urge consumers to clean their systems once a year plus keep the filters changed regularly. One thing the building code requires that is often ignored is the addition of a positive flow vent. Put a vent with a filter into the return air vent, and the filter on the inlet. I will bet that guy didn't have that and had blown in insulation. Mix it all together without the cigarette smoke and you have more potent allergy causing agents than you can imagine. Add the cigarette smoke and that increases allergies in susceptible individuals. You did the right thing buying a new one. 73 Jim de W5JO ----- Original Message ----- From: "patrick jankowiak" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Sunday, December 14, 2003 8:28 AM Subject: [AMRadio] blowers and smokers > I learned about heavy smoke in blowers in an interesting way; > > I needed a furnace unit to be the air conditioning blower for my shop > (don't need heat in Texas), and I got an old 3-ton one from a friend's > dad who had used it for 40 years and smoked constantly. > > It was pretty nasty, so set it outside and hooked up the blower motor > to AC.
