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?
