Question DetailsAsked on 2/13/2014

How much does it cost to replace ductwork in a 1500 sqft 1 story home?

We are replacing it because we are buying the home and want a fresh start with the duct work. We are also going to get a clean and sanitizing of the furnace and all vents.

Can run from $1000 range at extreme low end (though I don't think I have ever seen it that low except for a quonset hut type building with exposed ducts) to several thousand $, depending on difficulty of access and length and number of duct runs. Accessibility is by far the biggest factor affecting cost. I would expect not often less than $2000.

I would question replacing ductwork unnecessarily - unless it is badly torn (flex duct) or rusted (metal duct), there is little benefit in replacing it. For sheet metal duct, a good brush and airjet cleaning followed by seam sealing should make it near as good at a small fraction of the cost. Flexible duct can also be airjet cleaned, though a camera run should be made afterward to identify any rips or joint separations from the cleaning, and fix them.

Duct and furnace cleaning (aside from annual cleaning of firing chamber and A/C evaporator, is really overhyped - unless the dust accumulation is really bad and mildewing due to excess moisture (which is normally indicative of an A/C problem, not a duct problem), you are breathing cleaner air than if you walk outside, on the average, as long as you maintain your filters.

If it is rigid ductwork....leave it and they can be professional cleaned. If it is flex line, replace it with rigid.
