A couple renovation question for a project I'm considering....

[Mike B.]

Hi all,

Im looking at a 1940s SFR that has some sort of nailed on siding, short slabs nearly square not clear that its wood or not but has a wood texture. Anyway, im considering vinyl siding. Assuming I have a per square estimate, is it common to put vinyl over existing or do they tear out the existing?

Next, the house has a furnace with duct work throughout. Window ac units. Is it common or doable to replace the furnace with a heat pump/blower and use the existing duct work?

Finally, the electric panel is screw fuse type. Wiring looks good. Can i replace the panel as is with a modern breaker panel?

Thanks for any input,

Mike
