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.

Set an appointment for today about six weeks ago. Received a text three days before my scheduled appointment. Nice reminder heads up. The morning of the appointment I received a text from my technician, Ivan, that he was on his way. Ivan was even early of the suggested appointment window. Ivan performed service on my three HVAC systems. Ivan outlined what he would be doing today and offered tips to get the best out of my systems and recommended potential added service in the future as my HVAC system ages. Ivan as always, was friendly, courteous, treats my home with respect and professional. Solid, dependable service. Thanks Ivan. Appreciate your wisdom and honesty. I will ask for you again.

Mr. Crosby of RS Andrews is a true professional in his field. I had an issue with my furnace that was created by a previous contractor. When Mr. Crosby arrived, I explained my problem to him. He immediately inspected my system and was able to correct it not long after. Not only that, he was able to diagnose another issue that may have created my problem in the first place. I'm very grateful to Mr. Crosby and RS Andrews for their assistance. I highly recommend RS Andrews and Mr. Crosby to assist you should if you encounter an AC problem.

Daniel came to our house after hours when we called him about a water leak in a toilet he worked on previously. Turned out the problem is not related to anything he did previously. He scheduled an appointment to replace the toilet tomorrow. Daniel has been to our house twice, and we trust him implicitly. Good employee. Toilet has been replaced. Good job!

Max B. is their best field service agent. He should honestly start his own business. It’s rare for technicians to be sufficiently sociable while still highly technical. Installed a whole new panel for us.

Mr Mays was a great plumber and a very nice guy. He did his work and explained everything along the way. When he finished, he asked me at least 3-4 times if I had any questions. I feel very confident in his work. I would like to see Mr Mays when I have any plumbing issues.
