If your second floor feels more like a sauna than a bedroom retreat, you’re not alone. Many homeowners struggle with uneven cooling, especially in multi-story homes. The good news? The culprit is often hidden in plain sight — inside your air ducts — and there’s a proven way to fix it.
Why the Second Floor Stays Hot
Air conditioning systems are designed to deliver even cooling throughout your home, but several factors can prevent that from happening:
- Leaky Ductwork
Over time, small gaps, cracks, and loose joints can develop in your ducts. Conditioned air escapes into attics, crawl spaces, or walls — meaning less cool air actually reaches your upstairs rooms. - Dust and Debris Build-Up
Dirt, dust, and even construction debris can accumulate inside ducts. This narrows airflow, forcing your system to work harder and leaving upper floors underserved.
- Poorly Balanced Airflow
If your system wasn’t balanced properly at installation (or if dampers have shifted), airflow might be directed unevenly — first floor rooms may hog the cold air while upstairs rooms barely feel a breeze. - Insulation Issues
In some cases, ducts running through hot attic spaces may lose cool air before it even reaches the rooms. This is especially common in older homes.
How Duct Cleaning Improves Cooling
Professional air duct cleaning removes accumulated dust, allergens, and blockages that reduce airflow. When ducts are clean:
- Air moves freely, so each room gets its fair share of cool air.
- Your AC works less hard, which can lower energy bills.
- Indoor air quality improves, since you’re not recirculating dust and debris.
For many homes, cleaning alone can noticeably improve comfort — especially if it’s been years (or decades) since the last service.
Why Aeroseal May Be the Ultimate Fix
Even clean ducts can leak. Studies show that the average home loses 25–40% of conditioned air through duct leaks. That’s air you’re paying to cool — wasted in attics and crawl spaces.
Aeroseal is a patented technology that seals leaks from the inside out:
- A safe mist of sealant particles is blown through your ducts.
- The particles find and plug leaks — even ones hidden deep inside walls.
- It seals holes as small as a pinhole and as large as 5/8 of an inch.
- In just a few hours, leaks are reduced by up to 90%.
The result? More cool air upstairs, lower energy bills, and less strain on your AC system.
