The Financial Impact of a New HVAC System Installation
On average, homeowners can expect to recoup 5-10% of the cost of the new system in added home value. For example, if you invest $10,000 in a new HVAC unit, your home's value could increase by $5,000 to $10,000.
Ductwork has a maximum lifespan of 20-25 years, and starts to deteriorate around year 15. If your ductwork is more than 15 years old, you may need to have the ductwork inspected to see if it is time to replace it. If it is older than 25 years, you almost certainly need to replace the ductwork.
However, DIY ventilation replacement is a task you should leave to an HVAC expert. Doing this task on your own isn't recommended because: Faulty installation will waste energy. Air leaks can cause your utility bills to rise.
Homeowners insurance generally covers mold only when it's caused by a "covered peril" — an event your homeowners insurance policy will pay for, such as accidental water damage. These events must be sudden and accidental.
Highly valued items, such as jewelry, fine art, and collectibles, are often excluded from a typical policy for replacement costs.

Ductwork Replacement Cost Estimates

The Mess Is Minimal
If you don't have ducts, the spots that will see the most change are the closets and the attic, where we'll be running the ductwork. We'll have to cut a few holes in your ceiling to install vents and returns, but that's a very minor thing to do to drywall.
