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.

Pau Sum did an outstanding job at my home. He installed three faucets, two toilets, a new shower head, and new shower faucets, and everything was done perfectly. Pau was extremely professional, kind, and courteous throughout the entire process. He took the time to make sure everything was installed properly and working well before he left. It’s not always easy to find someone who does excellent work and is also such a genuinely pleasant person. I highly recommend Pau Sum and RS Andrews Plumbing.

Absolutely amazing experience with Raymond from RS Andrews. He was incredibly professional and kind and was very transparent with information both good and bad. When he left, I felt empowered with the right information to make the right decisions without feeling like I was “sold” anything. I’ve not had any actual services done yet, but as far as sales professionals go, I would absolutely have him back for other quotes.

My technician was Michael PowellI have never been more impressed with any technician. He not only completed the task that he came to take care of but he also found a couple of other things that could eventually be larger problems. Those things have been scheduled to be completed soon. Thank you Michael.
