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.

Called to get an appointment for one of my heating units that was not coming on (during a cold snap). Fortunately I could get an appointment with the technician who performs my routine maintenance, every spring and fall. . My appointment was for a four hour window the next business day. I received a call and a text of my technician, Ivan, arriving at the beginning of that four hour window. After his arrival we discussed the situation. He analyzed the situation and explained to me why the unit was not working properly. A blower motor was not working. Ivan ordered the part(s) and will be installed as soon as they come in. Pleased for a quick turnaround appointment and a quick answer to my concerns. RS Andrews works hard to keep their customers smiling.

From the initial phone call to the actual visit on-site, everyone was professional, kind, and responsive. I was scheduled a same day visit after hours! Ezekiel was quite helpful in not only locating but sharing his knowledge and expertise as he helped navigate my burst pipe and caved in ceiling. He made an overwhelming situation feel like it was going to ok and under control.

This review is based on a home visit. RS Andrews provided a plumbing estimate to my husband yesterday morning. We were very pleased with the experience with our tech, Mohamed. He came out to our home first thing Friday morning and provided a quote for a major plumbing repair. During his time with us he listened to exactly what we needed and provided information for what we specifically asked for without demanding extra unnecessary fees from the client who is already faced with a stressful and expensive situation. He was very polite and knowledgeable during the visit and provided a quick and detailed quote for the requested job. Regardless of outcome of our particular situation, they have gained an ambassador. We appreciate great customer service. I would certainly recommend calling RS Andrews for any plumbing or HVAC needs!

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

Not only is Mohamed a master plumber, he is a very nice and caring individual. When it was discovered that I purchased the wrong type of water heater, and started to get upset, he was calm and reassuring. He went out of his way for us, in many ways. We couldn’t be happier with the service and our purchase of a new water water heater thru Mohamed and RS Andrews and will be a customer for life.

Zoned HVAC was running non stop, not cycling off and one zone was not distributing heat adequately. Terrell arrived as scheduled . He was very thorough in investigating the issues I was experiencing. His troubleshooting efforts identified the problem/resolution which required a part to be ordered. Terrell answered my questions and explained next steps after order placed. . This was my time using RS Andrews. Very satisfied with the diagnostic services performed and the expertise of the technician.

I had my ducts cleaned by RS Andrews. Jose and Jayquon did a fantastic job. They were on time, thorough, respectful of my home, and answered any and all questions I had about the procedure. They cleaned up when finished, leaving no traces of the job behind. I highly recommend this company and Jase and Jayquon.
