Had the furnace serviced today and we were told there is fungus in the fuel tank,that the fluid tested positive for it. Does this mean we need the vents cleaned,as in the fungus was traveling throughout the house? We've noticed a worsening of our daughter's asthma and a relative who has been staying with us is currently having testing done for some shortness of breath. Everyone else in the house is fine. Furnace guy says no,it would have vented out as a byproduct of the combustion. What say you?
I'm not 100% confident of the answers here..
Fungus usually relies on spores, heat is one way for them to release their spores (one of the reasons there is usually a large "bloom" after a forest fire).
Which way those spores go after traveling through the combustion chamber would be a guess.
I assume combustion chambers are seperate from heating vents, through heat exchangers.. If that is working properly no spores should have a way to get into your house BUT spores can be mighty small and sneaky..
I WONDER if it would be possible to test your filters to see if any spores are floating around the inside of your house..
But these are just my ramblings..
My mom had/has respiratory issues and they ended up converting from an Oil Forced Hot Air system to a hot water system.. NO air ciculation, from her doctor's recommendation.
