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.

Lang wasn't able to arrive until 6:30pm as I had requested an undefined window. At first he couldn't find anything wrong with our brand new Lennox Elite compressor or unit. But it's as if he took it as a personal attack. Lang worked past 7pm, in a rainstorm, to discover two faulty coils in the compressor. Once he found the issue, it was repaired in minutes. I would highly recommend this tech.

The service tech, Waqas Shafqat, from RS Andrews performed winter system maintenance on our two HVAC units. We received a courtesy call about 30 minutes before he was due to arrive and he got here right on time. After a brief review about what to expect today, he got right to work. He was careful to put on shoe covers so as to not track in any mud or grass and checked the electrical portion of our downstairs unit. He also cleaned the thermo whatever it is that determines when to turn on and off the blower. He set the thermostat to a very warm temperature and let the furnace run. He then went to the upstairs unit and repeated the process. By the time he had finished with the electronics upstairs, he was able to return to the downstairs unit and determine that it was heating properly. When he had finished and closed up the downstairs unit, he was able to check that the upstairs was heating properly too. I followed along with him through the entire visit. While I may not know the names of all of the parts, I have seen enough of these visits to know that he checked everything and did all of what was expected very well. This is the second time that Waqas has been here. I was pleased to see that he was going to be performing our maintenance check today and would highly recommend him for any HVAC maintenance, service or inspection.
