Hello. I am renting a house in Idaho and the gas furnace is loud when
it goes on. It is not an explosion, it seems more like some sort of
resonance similar to an old motorcycle that goes on for a few minutes
before the hot air starts blowing. I have never heard a gas furnace
this loud. The landlords have vacuumed it and it hasn't helped. Any
suggestions or similar experiences? Thanks.

You could tell the landlords that you don't feel safe and ask them to
have it professionally inspected. Offer to split the cost with them
($45 - $75 in western NY) or if you have kids, use them as an excuse.
"I'm not trying to be pushy, I'm just looking out for my family."

If they refuse, play the "I'll call the local housing authority" card.
You might **** 'em off, but if you're really concerned that it's not
safe, and they are not willing to have it inspected on the chance that
it will fail, then you don't want them as landlords anyway.
