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.

Travon was very knowledgeable and professional. The company however needs more cohesion between electrican, plumber and the timely process of providing estimates. It's been over two weeks now and I still do not have a comprehensive quote for HVAC system installation with gas furnace. Competitors have been able to give me a quote upon initial consultation.

Will Macon was totally awesome! I’m a caregiver for my 89 year old mother who just came out of the hospital on Sunday. Our furnace went out on Tuesday. I called R. S. Andrews on Tuesday. Will was at our home on Wednesday morning. He examined our system and got us a GREAT DEAL on a new furnace and AC. It was awesome. The new system was installed on Thursday. By Thursday afternoon we had heat from a NEW FURNACE. Thank you Will and thank you R. S. Andrews for all that you do. You may have saved a life. Thank you!!!! Alane L. Sullivan

I found R.S. Andrews plumbing service through the TrustDale service guide. They sent out Pau Sam and he was so professional, polite and knowledgeable. He was able to locate the leak in my wall quickly and efficiently. I will now be recommending this company to my HOA to use in the future for their plumbing needs. I now have a plumbing company to recommend to my friends and family.

David Stitt did a fantastic job installing a tankless reverse osmosis system for me. He arrived early in the time window, which was greatly appreciated. I did have some concerns whether the RO system would fit under my farm sink, but David assessed the situation and came up with a plan that led to a successful installation. He works efficiently and neatly and conducts himself in a professional manner. This is the third time over the last 4 1/2 years that we have had David do various plumbing work for us and each time he has done a terrific job. I can highly recommend David Stitt of RS Andrews for all your plumbing needs.
