The cost to add a return air vent is between $200 and $750 per vent, with the average cost being about $350. Adding a return air vent can be a valuable upgrade to your home's HVAC system, improving air circulation and overall comfort. However, before you break ground on this project, you should understand the factors that influence the cost of adding a return air vent.
When it comes to adding a return air vent, several crucial factors can impact the final cost. Understanding these factors will help you budget appropriately and ensure that you get the most value out of your investment. While we explore the different factors that play into the final cost of this project below, speaking with a local duct installer near you is the best way to get an accurate estimate.
The new duct that connects your new return air vent to the existing ductwork can be a variety of materials and can also influence the overall cost. Different types of ductwork have varying price points and offer unique benefits. For example, while flexible polyester ducts range from only $1 to $4 per linear foot, they tend to be less durable and have the shortest lifespan. Sheet metal ductwork, on the other hand, is much more durable, but it has a higher price point of $4 to $12 per linear square foot.
| Duct Material | Cost per Linear Square Foot | Qualities |
|---|---|---|
| Flexible polyester | $1–$4 | Least expensive but shortest life span. |
| Flexible aluminum | $2–$5 | Not as expensive as other options, but prone to pest damage. |
| Flexible insulated | $2–$6 | Lightweight and durable, though prone to air leaks around the seams. |
| Fiberglass/fiberboard | $4–$7 | Well insulated and fire-resistant, but needs to be cleaned more often. |
| Sheet metal | $4–$12 | Most expensive option but less prone to mold growth than other ductwork options. |
The size of the return air vent plays a significant role in determining the cost. Larger vents require more materials and may involve additional labor, leading to a higher overall expense. In general, the cost to install a return air vent is between $10 and $20 per square foot
Labor expenses play a substantial role when adding a return air vent. Ductwork installation labor costs typically range from $5 to $10 per linear foot. In cases where the ductwork is situated in hard-to-reach areas, such as a cramped crawl space, additional labor or specialized tools may be necessary.
Deciding whether to undertake the installation of a return air vent as a DIY project depends on various factors. If you’re a skilled DIYer with some HVAC experience, installing the new return vent yourself will certainly save on labor costs. However, this project can be complex. It may involve cutting drywall and ductwork as well as considerations such as proper ductwork placement and sizing to ensure efficient airflow.
Local duct installers have the expertise to handle these intricacies, ensuring optimal performance and safety. For those lacking HVAC knowledge, hiring a pro is recommended, as it reduces the risk of costly mistakes and ensures the job is done correctly. Ultimately, the choice between DIY and professional installation should align with your comfort level, skills, and budget.
In addition to the primary installation costs, there are a few common add-ons that you might consider when adding a return air vent. Speak with your local ductwork installer to understand the costs associated with these extras.
While adding a return air vent, it's an ideal time to consider having your existing air ducts cleaned to remove any dirt and debris. Air duct cleaning costs between $150 and $780, depending on the type and size of your ductwork.
Insulating your ducts can have long-term benefits for your HVAC system's energy efficiency and performance, and it can help keep your home at a comfortable temperature. Air duct insulation costs roughly $1 to $6 per square foot.
If mold or asbestos is found during the process of adding a return air vent to your home, addressing them immediately is crucial. These hazardous substances can be dangerous to the health of you and your loved ones, so incurring the cost of testing, inspection, and removal is necessary:
Mold inspection costs between $200 and $650
Mold remediation costs between $450 and $6,000
Asbestos inspection costs between $250 and $700
Asbestos removal costs between $700 and $2,200
Saving money when adding a return air vent is a goal for many, so here are some cost-saving tips:
DIY if you can: If you have the necessary skills with drywall repair and the necessary HVAC knowledge, consider doing the installation yourself to save on labor costs.
Choose the ideal location: When deciding on a location for your return vent, choose a spot that minimizes the need for extensive ductwork modifications.
Go with an affordable duct material: Select cost-effective duct materials like flexible polyester or aluminum.
Bundle HVAC projects: If you have other projects on your HVAC to-do list—like air duct cleaning or HVAC inspections—consider bundling them together to potentially reduce overall costs.
