Fresh blown-in fiberglass insulation bringing this Naples Florida attic up to R38 for better comfort and lower energy costs. When this homeowner in Naples Florida reached out, the issue sounded pretty typical. The house just never felt quite right. The AC kept running longer than it should, and certain rooms stayed warmer no matter what. We see this a lot, especially in homes that have not had their attic checked in years. So we started where we always do. The attic.

What We Found Up There

At first glance, there was insulation, but once we looked closer, it was clear why the home was struggling. Coverage was inconsistent. Some areas were thin. Others had settled over time.
That might not seem like a big deal, but it adds up fast. When insulation is not at the right level, heat pushes into the home all day long. Your AC has to fight it nonstop. And honestly, this is where a lot of homeowners get misled. Just having insulation does not mean it is doing its job.

Why R38 Actually Matters

For homes in Florida, insulation needs to hit a certain level to work properly. That target is usually R38. Anything below that, and your home is basically leaking comfort.
That means:
• Rooms that never fully cool off
• Higher energy bills month after month
• Longer AC run times
• Uneven temperatures throughout the house
We see this exact setup all the time across Southwest Florida. According to ENERGY STAR, bringing attic insulation up to recommended levels can significantly reduce energy loss and improve indoor comfort.

The Retrofit Process

This was a full attic retrofit using fiberglass blown in insulation. When we first stepped into the attic, it was pretty clear what needed to happen. The existing insulation just was not enough to keep up with the Florida heat. We added new blown in fiberglass evenly across the attic, building it up to an R38 rating. That even coverage is what makes the difference. It fills gaps. It levels everything out. And it creates a consistent thermal barrier across the entire space. If you want to understand how insulation affects your home’s performance, the U.S. Department of Energy has a solid breakdown on how proper attic insulation reduces heat gain.

Fast, Clean, and Well Communicated

One thing that stood out on this project was how smooth everything went. From the initial visit to the final install, the whole process took about a week. The homeowner stayed informed the entire time. We shared progress photos during the job, and the crew made sure everything was cleaned up before leaving.
Her feedback says it better than we can:
“Great overall experience. Whole process took only a week for proposal to the finish product. Very thorough from start to finish. Crew kept me up to date with pictures during the insulation process and totally cleaned up before leaving.”

Why Blown In Fiberglass Works Here

Blown in fiberglass is a great fit for attics like this. It allows us to adjust depth across the entire attic so every section performs the same. No gaps. No low spots. And in a hot climate like Southwest Florida, that consistency matters more than people think. It is not just about adding insulation. It is about adding it the right way. If your attic has not been checked in a while, it might be worth taking a look. You can learn more about Koala Insulation of Southwest Florida on our website.

The Takeaway

This started as a common issue. A home that just would not stay comfortable.
It ended with an attic brought up to R38 and a home that finally feels balanced again.
Nothing complicated. Just doing the basics the right way.

If your home feels harder to cool than it should, your attic could be the reason.
