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.

My 87 year old mom’s 23 year old AC went out on a 95 degree day. I called RS Andrews at 7 AM. Repairman was onsite by lunchtime. The system was beyond repair. Sales rep was onsite before 5 PM. New Lenox system purchased by 6 PM. Installers and electrician onsite the next morning and project complete before 1 PM. Just WOW! Thanks RS Andrews.

First time using RS Andrews and Pau Sum was absolutely wonderful! He was extremely informative, sent pictures and videos of his work, and tested everything before leaving to make sure it was working properly with no leaks. I will be using them much more in the future!

David Stitt and his team did a great job today figuring out what was going on in our home with some complicated plumbing issues. Many other plumbers could not figure it out. Very knowledgeable and friendly. Thanks!

Upon coming home from a short trip on a Sunday we discovered that our AC was down. RS Andrews was able to send out a technician by mid-day Monday (during a heat wave). Anthony French was able to troubleshoot the problem and make the repair onsite. He was very pleasant, efficient & professional, and answered my many questions. He took the necessary time to help me understand the repair proposed and costs involved. Excellent job!

RS Andrews keeps my home systems working...waking up and finding a large pool of water on your kitchen floor can be frustrating! However, I called RS Andrews and they had an opening at that time...James Mays arrived 45 mins later replaced a faulty faucet and within the hour everything was back up and running smoothly! Thank you RSAndrews/Mr. Mays!

Excellent service from technician Waqas. Punctual, courteous, knowledgeable, patient and thorough. Everything you’d want! Completely satisfied! Plumber Zeke has been here twice. A third and possibly fourth visit are expected. First was an emergency response to a leak- he determined that the issue was HVAC rather than plumbing. For today’s visit he removed the water heater-necessary so that the HVAC installation team can put in a new system tomorrow. As before he was friendly, knowledgeable, efficient and effective. He made it look easy. Having assisted with this unit’s installation I’m fully aware that it’s far, far from easy. I expect that the subsequent new water heater installation will be of equally high caliber.

Great experience having the HVAC unit replaced in my condo. Max was very professional, from start to finish he kept me informed about each step, tested the unit thoroughly, and did a great job. Amber from sales was great as well, explaining the options and making the process super easy and efficient. Highly recommend.

I contacted RD Andrews to inquire about getting the attic above my garage insulated. Terry Taylor was assigned and he come to my place and gave me a very thorough opinion of the need and what I might consider. By the time he was ready to leave, I had decided that I would definitely move forward with the work as we discussed. I was pleasantly surprised to learn that the work could be done the following day and that Terry would be the installer. As promised, the next day Terry and his associate arrived when promised and within 2.5 hours, the work and all associated cleanup was complete. He provided me with photos of the "before and after". Terrific work! I am very happy with all that was done. You can bet that future need will be offered to RS Andrews. The photos are before and after.

I would highly recommend RS Andrews. I've used them in the past, but it had been a while. I needed a quote for something, and Loren Palmer came out and did a fantastic job. He was on time, early even, polite, professional, he came in and looked at what we needed done, and gave a quote on the spot, which was very competitive. They had great communication, highly recommend.

I had the pleasure of working with Jonathan Balom from RS Andrews when I encountered an issue with my air conditioner. From the moment he arrived, Jonathan demonstrated the utmost professionalism—he was punctual, polite, and incredibly efficient in diagnosing the problem. While the final recommendation was to replace my unit—an unexpected and potentially overwhelming outcome—Jonathan handled the situation with compassion and care. He gave me a moment to process the news and then took the time to thoroughly walk me through all of my options. What impressed me most was how clearly and simply he explained everything. He avoided technical jargon and made sure I understood why a replacement was the best course of action. Jonathan’s expertise, patience, and respectful demeanor made a difficult situation much easier to manage. I’m truly grateful for his help and highly recommend both him and RS Andrews to anyone in need of HVAC services.

Kwame Kilgore was a wonderful technician. He was pleasant, polite and kept us well informed about the work he was doing clearly and often. Earlier this year we had RS Andrews install a new water heater and after Kwame came to our home this time for the air conditioning repair we knew then using RS Andrews was the right choice for us. We will be your customer for as long as we own our home. 5 STARS!

Had a couple of small punch list items from a Home Inspection we needed to complete before Closing. Contacted R S Andrews on phone and their Call Center (Alison) was so helpful. Set an appointment for the next morning Received a super nice call (Ashley), first thing, to check all was still okay for the Electrician to come. Electrician arrived on time (Travon Jackson). He was extremely professional and friendly. Provided a quote for all work, and as it was acceptable, he did the work right away. In and out in 30 mins. A great experience and one I would recommend to people looking for fast, efficient, professional service for any electrical job. Travon had a ceiling fan replacement and a bathroom fan to fit later that day to give an idea of the breadth of jobs they are able to accommodate.
