How Much Does It Cost To Add A Vent To Existing Ductwork?

Vent placement costs are determined by where the vent is located, as well as the number of additional materials required. It usually costs between $200 and $2000 to add a vent to existing ductwork.

It is not uncommon for a vent to cost from $150 to $250 to be added to existing ductwork. It is a good idea to install a vent if you do not receive enough heat or cooling in your room.

Occasionally, this vent may need to be a return vent, which means that it can facilitate your HVAC system’s return to work. When this occurs, the system runs more efficiently.

You will pay the most for your new vent depending on how long it is from the main system to the new branch. In order for this new branch to travel far, your system configuration needs to be perfect.

Ductwork Installation Cost In An Existing Home

Ducts are typically priced between $12,000 and $18,000 to be retrofitted into existing homes. It is more challenging to install ducts in a home without any existing ductwork, which has finished walls and floors. In walls, floors, and ceilings, holes must be cut for vents and returns.

It is not uncommon for installing ductwork to require running it through or under floors, and if that is not possible, it may be necessary to run it through attics, crawlspaces, closets, and under stairs.

A significant increase in installation costs may result from this. Obtaining the right size ducts may also prove problematic. Air can be transported through larger ducts, but they require more space. It is common for retrofits to have ducts that are smaller than optimal to enable them to navigate.

Upgrading to Forced Heat

The average cost of installing or replacing a furnace is $4,500. Heat pumps can be installed for a cost ranging from $4,100 to $7,200 and provide both heating and cooling.
