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.

Michael Powell approached issues systematically, carefully analyzing symptoms and collaborating with me to identify causes. He had a knack for explaining complex technical concepts in simple, understandable terms. When he left, I felt more confident and better prepared to manage my system, having gained a clearer understanding of how it works through his cooperative and patient approach.

* changing my review Nick was outstanding

After having a pretty bad experience with a previous RS Andrew’s tech (see below) I will say that working with Nick was refreshing. He kept me posted the entire time during the work process. He was extremely clear in his communication and apologetic for the behavior of the other tech (not something he needed to apologize for). He stayed to make sure that everything worked as it should prior to leaving and was extremely thoughtful and polite in the way he communicated to me and helped me arrive at a decision. I could not have asked for a better technician and am extremely grateful for his professionalism and his outstanding work.

Old review…
Second time I have had this issue despite having the service plan and having had spent nearly a grand when it was a supposed heat pump talking to panel issue and had to have whole new panel installed on a new HVAC system. Now that winter has come back around after my Winter Service my heat began running all the time. Today’s technician could not explain to me why when I set my heat on 65 it would continue to run even when it got to above 65. He thought he fixed it yet I alerted it to him that the system has once again reset once he had worked on the unit outside and was ready to walk out the door. I now am awaiting a call from RS Andrews for another technician (no 2nd tech fee at least) just an electric bill that is 3 times its normal rate and a house that keeps trying to heat and no clear explanation. Technician was extremely polite but concerned about service needs especially given what I have paid. However I came to learn that the technician did not note that someone needed to come back out. No one called me. I called and there are no notes. They can not get a hold of the technician after I called for the second time.
