What causes duct leaks in Peachtree Corners homes?

Age, settling, vibration, and poor installation create seams that separate. Corrosion, rodents, and physical damage also cause holes. Spring and fall temperature swings stress old ductwork. Inspection identifies the source so repairs address the root cause, not just the symptom.

Can duct leaks be repaired or must ducts be replaced?

Many leaks can be sealed or patched. Small holes receive mastic sealant or metal repair tape. Moderate damage gets fiberglass mesh reinforcement. Severe crushing or extensive corrosion may require section replacement. A technician assesses damage and recommends the most cost-effective repair.

How much energy do duct leaks waste?

Significant leaks can lose 20–30% of conditioned air before it reaches the room. This forces the system to run longer and harder, raising energy bills and reducing comfort. Sealing leaks improves efficiency immediately, lowering cooling costs during Peachtree Corners' hot summers.

What is the difference between duct repair and duct sealing?

Duct repair fixes physical damage like holes, disconnections, and crushed sections. Duct sealing closes air leaks at seams and connections using mastic or tape. Both services often work together to fully restore ductwork integrity and performance.

How long do duct repairs last?

Professional repairs using mastic sealant and quality tape typically last 10+ years. Homes with ongoing settling or vibration may need re-sealing sooner. Regular inspections help monitor durability and catch new damage early.

Duct Repair in Peachtree Corners, GA

One Hour Heating & Air Conditioning® of North Atlanta

Peachtree Corners neighborhoods vary widely—70s subdivisions sit near modern developments, and each housing style presents unique duct challenges. Leaks, gaps, disconnections, and damage waste energy and reduce comfort. Professional duct repair restores efficiency and airflow across all home ages and neighborhood types.

Duct Problems in Established Neighborhoods

Original ductwork in 1970s-1980s Peachtree Corners homes shows wear: sagging ducts pull away from connections, tape fails and peels, and metal corrosion creates holes. Temperature swings between spring and fall stress old systems. Older homes also experience settling and shifts that flex ductwork, creating gaps at seams. Identifying and repairing these age-related issues prevents energy loss and temperature imbalances between rooms.

New Construction and Installation Issues

Newer Peachtree Corners developments sometimes suffer installation mistakes: loose connections, improper hangers, and undersized ducts. Settling of new homes can also shift ductwork and disconnect flex ducts. Even minor misalignment reduces airflow and causes hot or cold spots. Inspection and repair of newer systems catches issues early before major performance problems develop.

Common Duct Damage Signs

Visible damage includes holes, crushed sections, disconnected flex ducts, and peeling tape. Performance signs include uneven temperatures across the home, weak airflow in distant rooms, and higher energy bills. Dust around ductwork joints indicates leaks. A professional inspection uses visual checks and pressure testing to locate hidden damage inside walls and attics that affect system efficiency.

Dean did a great job helping us out. Between Dean and Daniel out in the field, and Caren and Heather up in the office, this company has helped us feel that not only do we matter as customers, but also that they care about their employees and want to see them thrive. 10/10, highly recommend.

We had an unexpectedly stressful situation where we needed to replace our HVAC system, and One Hour Heating & Cooling was one of several companies we contacted for an estimate. From the very beginning, Rob, the owner, stood out. He was incredibly down-to-earth, honest, and took the time to explain everything to us in detail without making us feel pressured. After meeting with several companies, Rob was by far our favorite, and we felt very comfortable choosing his team for the job. It truly felt like we were becoming part of a family rather than just being another number at a large company, and that made a huge difference to us. The installation team was just as impressive. They were professional, respectful, clean, and truly top-class guys. They did an excellent job and left everything neat and tidy. We’re really looking forward to working with Rob and his team going forward. It’s refreshing to find a company you can genuinely trust, and we’re very happy to recommend One Hour Heating & Cooling to our friends and family! Thank you, Rob and team, for making an unexpected and stressful situation so much easier!

1) When our air conditioner failed after hours, we actually reached a real person who scheduled our repairs for the next day. 2) Greg Nieves was the expert who arrived, and we were immediately impressed with his reliability, knowledge, and efficiency. He knew what he was doing, quickly gained our trust, and guided us to the best option. When one finds integrity and pride in a job well done, it is important to acknowledge that. We didn't know about One-Hour before yesterday, are well satisfied and have now become a regular client.

Zo was fantastic! He came to my home to diagnose an issue with my AC and immediately impressed me with his knowledge, professionalism and decades of experience. He arrived prepared with the right tools, took the time to explain what was happening and helped me understand the different options available. Most importantly, he genuinely cared about finding the right solution for both my needs and my budget rather than simply pushing the most expensive option. I really appreciated his honesty, expertise and willingness to help and I would highly recommend Zo from One Hour Heating & Cooling to anyone in need of HVAC service!

Excellent service and top quality repair technicians. We brought out another company and they insisted we needed to spend over $10,000 for a new A/C system and for $267 One Hour Heating and Cooling repaired our A/C. We are so grateful to work with a trustworthy company. I highly recommend them!

Gage did an amazing job with repairing my HVAC unit. He had the part I needed a day before he came out to my home. He explained everything he was doing and answered all of my questions. I needed a blower motor. He completed the job in about 45 minutes. Gage arrived when he said he would. I will most definitely be calling One hour heating and AC again. Reasonable pricing and awesome customer service. Thanks again Guys

Jammie was very personable and professional. She took pictures of the HVAC unit and explained everything in great detail. She even wore shoe covers before entering my home showing great respect for my property. She was a delight to deal with and is definitely an asset to your company.
