Your HVAC system might be working overtime without you even realizing it—all because of tiny cracks and gaps in your ductwork. These hidden leaks can cause uneven temperatures, dusty indoor air, and energy bills that keep creeping upward. That’s where our duct sealing services come in. The team at R.S. Andrews tracks down inefficiencies and seals them with precision, helping your home stay comfortable year-round. Better airflow, healthier air, and a more efficient system start with attention to what’s behind the walls.

Signs Your Ducts Might Be Leaking

Even well-maintained HVAC systems can lose efficiency if the ductwork isn’t sealed properly. Leaks can develop over time and quietly chip away at comfort and performance. Spotting these warning signs early can help you avoid bigger issues.

  • Uneven temperatures between rooms: If some areas of your home are consistently warmer or cooler than others, leaky ducts could be diverting airflow.

  • Unexplained spikes in energy bills: Higher heating or cooling costs may be a result of conditioned air escaping before it ever reaches your vents.

  • Excessive dust or poor air quality: Leaks often pull in attic or crawl space air, introducing allergens, dirt, and contaminants into your living space.

  • Noisy vents or airflow problems: Whistling sounds, weak airflow, or pressure issues may point to gaps or disconnected duct joints.

  • Longer HVAC run times: If your system seems to run constantly, it might be working harder to compensate for air loss in the ductwork.

Schedule today! We’re ready to deliver expert service and a smile to your door.

Duct Sealing Services We Provide

Comprehensive Leak Detection

We begin with a detailed inspection of your duct system using advanced tools to locate even the smallest leaks. This step helps us identify problem areas often hidden behind walls, ceilings, or insulation.

Professional Duct Sealing

Using mastic sealant, metal tape, and proven sealing techniques, we patch and reinforce weak points throughout your ductwork. Our goal is to stop energy loss and restore strong, balanced airflow to every room.

Airflow Testing & Balancing

After sealing, we test your system’s performance to make sure airflow is evenly distributed. Balancing your system helps reduce strain on your HVAC and improves temperature consistency throughout the home.

Attic & Crawl Space Duct Insulation

If your ducts run through unconditioned areas, we recommend insulating them after sealing. This added layer prevents energy loss and keeps your system operating efficiently in every season.

Our tech, Mohamed, did a great job checking the gas line to the fireplace. We are grateful to him, and RS Andrews, for helping us on such short notice so we could prepare for a winter storm event.

Very good job! But charging me $413 for less than two hours of inspections and some work seems pretty high. I should have listened to my wife to get several estimates first.

RS Andrews is an Atlanta institution and continues to be an excellent service.provider. After our kitchen sink clogged, two handymen failed to show up. On the 6th day I called RS Andrews and they arrived promptly the next morning. The gentleman arrived worked diligently, explaining to me, each step of his work, and what he had found, discovered that he needed a additional tool, and instead of leaving, he called another Service technician to bring the tool and join him. The sink clog was severe, and the two of them worked for several hours, until it was finally resolved. Both young men were pleasant, manly, did not speak on their cell phone and a loud voice while they were in the house, they were intrusive. They were considerate of me when I was on the phone and most importantly, they did not abandon the job because they needed another tool. I believe that they will both be fine businessman, and they were wonderful in their performance. I would not hesitate to use them again. My husband had scheduled the handyman, thinking it would be less expensive. Lesson I wish I had learned in my teenage years instead of in my 30s is that one is merely Pennywise and pound foolish to Attempt To Find inexpensive labor or paint offense when time is precious and in the end, you spend more trying to get the work done, buying the materials, etc. RS Andrews is a good value. Time is all that we have, once spent it can never be recovered. The real cost of services is time, dollars, solutions and whether the work lasts.

Update Friday 01/23/26: After going with Paul’s recommendation to replace 2 parts above the water heater tank, it seems like it is not leaking anymore in the drip pan! Gave it 24hours to see if the pan was dry, and it is! Greatful for Paul’s expertise and saving us $$$ to not replace the entire unit yet. We will monitor it for another few days. Thanks again, Paul! Paul was very knowledgeable and gave his expert advice on our water heater issue. We are going with his recommendation to replace 2 parts instead of the whole water heater. I am confident that he is right. Thanks Paul and see you in the morning for completion!

Chris Jones - a hard-working employee of R.S. Andrews. Reported a water leak issue. Chris arrived and went right to work to determine to source of our leak. For further assistance he referred us to a company who specializes in water damage repair etc. Chris followed up with a phone call to inquire how we were progressing with our problem. We appreciate his concern and his experience in these matters. Thank you, Chris! Michael
