AC Duct Replacement in San Antonio, Schertz, Converse, Floresville, Elmendorf, New Braunfels, and Surrounding Cities
Few homeowners know how important ductwork is for a well-functioning HVAC system.
HVAC ductwork or air ducts are a type of conduit responsible for supplying each room with cool or warm air. While this explanation seems simple, there are several types of air ducts.
The complexity and cost of ductwork replacement projects depend on the type of ducts a system requires. HVAC units have one the following:
Sheet metal ducts: These are made from either aluminum or galvanized steel. They’re the most durable option on the market and the least susceptible to mold. Additionally, they’re virtually rustproof, especially galvanized steel options that feature zinc coating.
Flex ducts: These air ducts have a steel wire core surrounded by polymers and insulation. Flex ducts appeal to customers because they’re budget-friendly, easy to install, and lightweight. They’re also suitable for spaces where it’s challenging to install more rigid ducts.
Fiberboard ducts: These ducts feature two layers. The first is inorganic fiberglass, while the second is a fold that minimizes water vapor and air damage. These models are usually the most affordable and prevent noise without difficulty. However, one downside homeowners and tenants should keep in mind is that this air duct type may restrict airflow.

Air Duct Replacement Cost in San Antonio
Regardless of the type of ductwork a system uses, well-maintained ducts are necessary for good indoor air quality. Heating systems produce trace amounts of carbon monoxide, a highly toxic gas. However, we typically don’t have to worry about carbon monoxide inhalation because the ducts carry the gas outside the home. The good news is that routine checkups bolster home safety. A qualified technician will inspect the ductwork and determine whether it’s time for HVAC duct replacement.
Duct replacement requires a high level of technical knowledge and is not considered a DIY project. An expert will find the most durable replacement options and ensure all the connections are airtight. Additionally, they’ll inspect the other elements and ensure they’re in good condition.
Another factor homeowners should consider when replacing ductwork in attics is insulation. Unless the attic is adequately sealed, the ducts become heated and warm the cool air passing through them. Contact a professional to give the ducts sufficient support by installing quality vents.
The cost to replace ductwork varies greatly depending on the job’s complexity. For example, it can cost between $460 and $2,060 to cover air duct replacements. Typically, homeowners pay less for replacing ductwork in attics because the ductwork is more accessible. On the other hand, the project cost may double if the job involves retrofitting a home with unique layouts and closed walls.
Of course, the pricing also depends on the material. Flexible polyester options are the least expensive but have the shortest life span. Flexible aluminum ducts are more durable than their polyester counterparts but are susceptible to pest damage. While galvanized steel ducts are the most expensive, they have the longest lifespan and offer premium durability.
Signs That Air Ducts Need Replacing
Homeowners concerned that they need to replace their HVAC system’s ductwork should watch out for the following warning signs:
Hot and cold spots: Temperature discrepancies are a nightmare for everyone. One room is too hot, while another is noticeably colder. The difference can sometimes exceed three or four degrees. Measure the difference with a thermometer, and contact an HVAC company if the reading confirms the suspicions. The technician can quickly diagnose the issue and suggest the most suitable solution to eliminate hot and cold spots.
Poor airflow: Place some paper in front of the supply vent’s opening. Sufficient airflow should move the piece of paper, but it won’t bend if issues exist with the ductwork.
Higher utility bills: Under-insulated air ducts allow as much as 30% of conditioned air to escape, leading to higher electricity bills. Unfortunately, many homeowners miss this warning sign early on, as the increase tends to be gradual.
Loud noises: Although older HVAC systems produce some noise, it’s in the background. But rattling and whistling indicate that the ductwork may struggle to do its job. Call a technician who will identify whether the ducts are damaged, loose, or disconnected.
Poor indoor air quality: More dust inside the home indicates compromised air quality. Loose connections and holes allow irritants like pollen and dust to infiltrate the ductwork, causing problems for people suffering from allergies and respiratory conditions.
But what causes ductwork issues?
Air vent placement: Air vents should never be installed in remote areas like closets because the location prevents air from reaching all living areas. Similarly, furniture shouldn’t block the vents since the HVAC system will use more electricity to meet the home’s cooling or heating demands. This extra pressure can significantly shorten the system’s service life.
Twisted or tangled flex ducts: Unless the installer stretches flex ducts and cuts them to the correct measurements, the runs will be twisted or kinked. This installation mistake restricts airflow and results in costly repairs.
Unnecessary bends: Bends in the ducting is another installation flaw that creates air pockets that restrict and slow airflow.
Pests: Bugs and rodents sometimes work their way inside the ductwork and block airflow. Regular ductwork maintenance identifies problem areas, and technicians can patch holes that rodents may use as entry points.
Mold: Air ducts should always be moisture-free to prevent mold development.
Leaks and corrosion: Wear and tear erode old seals, resulting in air leaks. After moisture reaches the ductwork, it’s a matter of time before the ducting breakdown.
