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.

Brandan delivered the customer care I expected. I am very satisfied with his work performance and detailed attention he gave to improve the performance of my hot water tank. I mentioned to Brandan my tub faucet was leaking and he did not hesitate to inspect the leak and repair the leak right away. I was happy to get both my hot water tank flushed and the leak repaired during Brandan’s visit. He followed up with explanation of causes and preventive work he did to improve the life span of my hot water tank. He had the right parts on his truck to fix the leak. So, I saw he was prepared to offer customer service when necessary. Brandan was pleasant and courteous. I welcome Brandan back again for future services. I always appreciate R S Andrews time and response management systems because I’m always notified when the technician is in route to my home. For years, I have been pleased with both products, services, and customer service delivered by the company. I am pleased to be an R S Andrews Club Member.

James was the absolute best! He was very knowledgeable and super informative on the plumbing that needed to be fixed! He was super trustworthy and very thorough while doing the work being completed! He was able to replace a few copper lines and add a new pressure reduction valve on my home within a few hours. I highly recommend R.S. Andrews!

I had the most unusual electrical gremlin at my house. Justin was absolutely AMAZING!!!! I cannot speak highly enough of the effort he put into finding the gremlin. He never gave up and found the issue preventing me from having to rewire the entire upstairs. I cannot thank Justin enough. I would HIGHLY RECOMMEND JUSTIN if you have an unusual electrical concern that no one else can figure out. Justin is your man.

The service was top tier as always. All three of the gentlemen that came out to service my system (Colin French), sales (Ladarian Raymond) and installation (Carlos Perry) were all very knowledgeable about the equipment. They had excellent customer service and were thorough in their explanation of the systems. The company returns your calls and set appointments in a timely manner. I have used them in the past and they have always delivered the same outstanding service.
