Preventive replacement of Honeywell Ignition Module/HSI?
My HVAC service person is coming soon.
I am the second owner of the home. Previous owener had HVAC Co. replace the Honey Ignition Module in 1999 because of "no heat".
So my guess is that 8 years is the approx. life of the Honeywell Ignition Module/HSI? Is this correct?
I hate to have no heat in the middle of the night, so is it a good idea to ask the service person to replacement of Honeywell Ignition Module/HSI, knowing that these parts are now 9 years old?

You didn't say why the service tech is coming out. But due to the apparent age of your furnace, besure that he/she checks your heat exchanger.
In answer to your question, electronic parts are difficult to justify replacing on a non-specific problem. I other words, they are usually a fail or no fail part.( Short of a loose/cold solder joint). I don't replace them unless they are bad, because some last 10 plus years others shorter. No way to tell, until they fail.
Oh, forgot to mention that the service person is coming out for routine winter tune-up.
