Return Air Vent Installation Cost Factors

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.

Vent Size

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

Duct Material

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 MaterialCost per Linear Square Foot
Flexible polyester$1–$4
Flexible aluminum$2–$5
Flexible insulated$2–$6
Fiberglass/fiberboard$4–$7
Sheet metal$4–$12

Labor

When adding a return air vent, labor expenses play a substantial role. 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.

DIY vs. Hiring a Pro to Install a Return Air Vent

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. Understanding the costs associated with these extras can help you plan your project effectively.

Air Duct Cleaning

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.

Duct Insulation

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.

Asbestos or Mold Problems

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:

Ways to Save Money When Adding a Return Vent

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.

Frequently Asked Questions

Return air vents can be located in any room of your house, but it's essential to choose the location strategically. Placing a return vent in a central area, such as a hallway or a larger living space, is more effective for balanced airflow and temperature control throughout your home. However, factors like the HVAC system's design, your specific heating and cooling needs, and the accessibility of ductwork may influence the optimal placement of a return air vent.
