How long does duct installation take?

Full duct installation typically takes one to three days depending on home size and complexity. Extending ducts to a single room may take a day. A technician provides a timeline after evaluating your project.

Can I add ductwork to a finished basement?

Yes. Adding ducts to finished basements is common in Sandy Springs. New ductwork is routed from the existing system, properly sized for the space, and provides much better comfort than portable heaters.

What type of ductwork is best?

Most Sandy Springs homes use flex duct because it's easier to route through attics and crawlspaces. Rigid metal duct provides the best airflow but needs more space. Many homes use a combination of both.

Does new ductwork need insulation?

Yes. Ductwork in unconditioned spaces like attics must be insulated to prevent energy loss. In Sandy Springs, attic temperatures get extremely hot in summer, and uninsulated ducts lose significant conditioned air.

Can my existing HVAC handle new ductwork?

That depends on the addition size and current equipment capacity. A technician evaluates whether your Sandy Springs home's system can handle the load. If not, equipment upgrades or separate zones may be recommended.

Duct installation in Sandy Springs provides properly designed ductwork that delivers the right amount of heated and cooled air to every room. Whether you're finishing a basement, adding a room, or converting a condo space, new ducts make a real difference in comfort.

When Sandy Springs Homes Need New Ductwork

Sandy Springs homeowners commonly need new ductwork when adding living space — finishing a basement, building an addition, or converting a porch. Condo and townhome conversions often require completely new ductwork because original installations weren't designed for the modified layout. Homes undergoing extensive renovation sometimes need duct replacement because existing ductwork is too deteriorated to reuse. In older Sandy Springs homes, ductwork that has served for decades may be more practical to replace than continue patching.

Designing Ductwork for Your Sandy Springs Addition

Proper duct installation starts with designing the system to match your HVAC equipment and home layout. Each room gets the right amount of airflow based on size, location, and heating-cooling requirements. Duct runs are planned to minimize length and bends, keeping airflow strong. In Sandy Springs homes, ductwork typically runs through attics or crawlspaces, and proper insulation around ducts prevents energy loss in unconditioned spaces. The installation crew ensures every joint is sealed, every run is properly supported, and the system is balanced for even airflow.

Integrating New Ductwork with Your Sandy Springs Home

Adding ductwork to a new room requires tying into the existing system without disrupting airflow elsewhere. A technician evaluates whether your current HVAC can handle the additional load and designs new duct runs to integrate properly. Sometimes the existing system accommodates the addition with new branches. Other times, equipment upgrades or separate zones are needed. The goal is making the new space just as comfortable as the rest of your Sandy Springs home.

We called Dunn HVAC late Saturday night after realizing our air conditioning was not working. We paid the emergency trip charge and asked them to come the next morning. Cory Thrasher arrived as promised, quickly assessed the situation, clearly explained what he believed needed to be done, and repaired the unit promptly. Before he left, I asked about future maintenance because my husband and I do not always keep up with those things as well as we should. Cory was very helpful, gave us a great discount, and set us up with a maintenance agreement that includes service twice a year for both our heating and air conditioning systems. We felt very relieved knowing the system will now be properly maintained, and our air conditioner is working perfectly. Cory was professional, knowledgeable, honest, and easy to work with. We highly recommend Cory Thrasher and Dunn HVAC!

Gordon was here and did a great job servicing my ac unit. We also discussed the fungus growing in my unit and he reviewed the light packages to take care of that. He also reviewed some add one that I should consider. He very well represented One Hour AC.

Happy customer indeed. Charlene showed up and pinpointed that the Capacitor of the AC was bad. She changed it and made the house so comfortable. They are the only company that was available the same day. I am very very pleased and happy that I called them. Charlene was so kind and calm sharing me the plan they have to offer. The total was $378 and offered me the plan the silver for $16 a month and they will come to my house twice a year. I signed up for the silver plan or I Would’ve paid $478 if no plan. Thank you one hour for coming to my house.

Great job, great timing. When others could not One Hour could. They saved us just before heat wave. Our AC had to be exchanged after being hit by lighting. I used One Hour guys again, like I did when buying my house. They are great, reliable and friendly. Thanks a lot.

Brad was fantastic. He was knowledgeable and fast. He took the time to answer some questions I had that were beyond the maintenance visit and went back to check thermostats and our multi-zone system. Top notch!

The people from this organization are great to work with! Micah came out to put together some quotes for replacing our entire HVAC split system. While he was with me he found a problem with our AC and fixed it on the spot. Amazing Experience with a very personable, professional HVAC expert. He quoted 3 solutions and reviewed all of them with me before he left. He is patient and knowledgeable and answered all of my questions as we reviewed the solutions he created. I highly recommend working with Micah and his organization.
