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.

Sun. Jan. 11, 2026 3:00 P. M. This is my original survey text I sent Mon Dec. 29, 2025 3:44 P. M. after service was completed, text returned and R. S. Andrews sent me website to post survey. R. S. Andrews Technicians Luke & (Amir, who was in training) were absolutely great. Luke called me as Nick told me he would. They were prompt, courteous, and presented well. No problem when I mention to wear shoe covering (booties). They checked out all they were looking for to start and complete job. Luke is a great, skilled, and to the point guy. Amir listened, took notice to what Luke requested of him, so the process was thoroughly done right. Luke did not mind me asking questions and answered extremely well. He made me aware of a possible hazard he came upon in the chimney. He was able to relay information over the phone to homeowner, Mr. C., who was on his way home. He also told Mr. C. he had tightened a loose wire on wall by dryer. We thanked them both. We were/are pleased with R. S. Andrews service and we will definitely refer them to others. Superb technicians and service today. Thank them for respecting me and my home. We thank Trust Dale Cardwell for letting us know about this awesome company. Cordially, The C & H families
