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.

March 27, 2026 Still great! Neil Johnson once again did an awesome job addressing and resolving my plumbing issues. I had a small leak under my kitchen sink. He quickly assessed that my faucet was the problem. We were able to get a new faucet and he installed it the same day. Neil also proactively replaced an expansion tank that was going bad to regulate my water pressure and mitigate future potential problems. R. S Andrew’s has top notch technicians that go above and beyond to get the job done and Neil is one of the best! Plumber review I contacted RS Andrew’s plumbing service requesting they send out a technician to troubleshoot and resolve a water leak that had been running all week in my garage. I had previously contacted my warranty company who sent out a plumber who could not find the source of the leak and who determined that it was not a plumbing issue. He suggested that it was an HVAC problem and I wasted valuable time and money having a HVAC technician come out to look at it without any resolution. It turns out that it was a plumbing leak after all. Neil the plumbing technician for RS Andrew’s did an outstanding job quickly uncovering the source of the leak and resolving the problem within minutes of his visit. I was very impressed with his knowledge and his ability to resolve the issue so quickly. Kudos to Neil for his professionalism and skills and to RS Andrew’s who made my problem a priority by sending out a technician on the same day of my request. I can now sleep at night knowing that this leak has been stopped and I can now move forward with repairs. I will definitely use this company for my future plumbing needs. RS Andrew’s staff is the best!
