Furnace service.

[SteveSkinner]

I'm about to hit the road for 8 weeks heading as far north as Boston and Niagara falls.
Is it reasonable to assume that since the furnace worked perfectly when I last used it in October that it will perform perfectly.
Does it need servicing or do you only fix it if it's broke
Thanks in anticipation

Givin it a quick blow is always a good option to just pull the cover and blow it all out is never a bad idea

I've had several RV's and never even thought about servicing a furnace.

And still won't.

I think it's a non issue and wouldn't worry about it.

Thank you thank you. These are the answers I love.
If it ain't broke don't fix it
