Hot surface igniter education

The hot surface ignitor is a electrical component that is wildly used in most newer manufactured gas furnaces, like Bryant, Trane, Carrier, Rheem, and lennox just to name a few. Every time your furnace comes on the hot surface igniter is electrically energized with 120 volts and glows red hot for about thirty seconds igniting the gas at your furnace, similar to the way your kitchen counter top toaster works, when you push the lever down the element in the toaster turns red hot to toast your bread. Because your furnace may cycle on and off, up to four to six times per hour during the winter season, the hot surface igniter gets used a lot. Like the equivalent of you using your toaster 25,920 times in a six month period. Because it gets used so much the hot surface igniter is the only component of the gas furnace that needs to be replaced routinely, about every four to six years on average. There are two types of hot surface igniters that are used, the first one is a hot surface igniter made from material called silicon carbide, and this is the older style ignitor that should be handled with care because it is very fragile. The second newer type hot surface igniter is made from material called silicon nitride; this is a more durable material and is not as fragile as the silicon carbide, the more durable silicon nitride igniter will last longer, giving you sometime twice the life span. If your furnace has the old silicon carbide ignitor and you have a technician replacing it, you may want to ask about upgrading to a newer hot surface silicon nitride ignitor that may last longer.

Mysterious black streaks around furnace supply vents

Friday, January 22nd, 2010

Every once and a while I will have a customer ask me a question, like why is my air filter for my furnace getting so black and dirty so quickly after replacing it, this is usually followed up with another question like, do you know why I have these mysterious black streaks coming out of my supply vents, or maybe they point out black spots around the floor vents that shows up a lot more on white carpet. Well after years of hearing these same questions over and over again, I am very pleased to give you what I think maybe the answer to this mysterious question, please can I have a drum roll? If this is your same question and you have these symptoms in your home, I would be willing to bet you or someone in your home burns scented candles, I found that just about everyone of the customers that asked me about these mysterious black streaks in their homes, burned scented candles. So there you go, if this is you and you have these mysterious black streaks, give this a try. Clean up the black streaks or paint over them and clean your carpet, put in a fresh clean air filter, and the hardest part will be to give up your scented candles for a short time. If the mysterious black streaks don’t return you have your answer, if you still are getting the black streaks my advice to you would be have a licensed heating company come out and inspect your furnace for safety reasons.
