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.

David Rosati was very professional and checked out our new heat pump. He added vibration dampers to help with the noise the system was making and then proceeded to make sure it was working well. This was very much appreciated as we have been experiencing temperatures as low a 8 degrees. I'm always happy when David comes to service our HVAC. Terrell Thomas was very thorough and professional. i was very pleased with his service. He checked out both heat pumps and the three zones in my house and assured me all was working properly, a necessity with 24 degree weather. Both David Rosati and Amber Magnus were exceptional! Amber Magnus was very professional and quite helpful and knowledgeable! David was very thorough and did a great job as usual for R.S. Andrews employees. David explained everything he was doing and I enjoyed the time he spent explaining everything. Terrell did a great job and explained all he was doing and why the capacitor needed to be replaced. i was very happy with him. Nick Husley did a very thorough job. He was prompt, friendly, and answered all questions wel. Nikia was very thorough in checking out the AC system. I feel he was extremely honest in pointing out future repairs that may be needed. Nakia again was very thorough checking out the heating system. Ivan Medina was prompt and thorough in maintaining the AC system. He explained what he was doing and why some part needed to be replaced. He showed me the readings of the failing parts and the readings on the replacement parts.
