They Replaced the AC. The Upstairs Still Wouldn’t Cool.


Kul told us something we’ve heard quite a few times.


“We already replaced the AC.”
She kind of shrugged after she said it.

The upstairs still wouldn’t stay comfortable.
That’s the part that didn’t make sense to her.
The equipment wasn’t really the problem.
The house was built in 2007, so it wasn’t especially old.


The attic, though…that told a different story.


People had been up there over the years. Contractors. Electricians. Probably cable installers too. You could see where insulation had been pushed around and flattened from people walking through it.


There were even a few spots where it looked like something had been living up there at one point.
Nothing unusual.


Just years of things adding up.
We checked the whole attic
We weren’t just looking at the insulation.
We checked the ventilation, the airflow, and how the attic was holding heat.
It was pretty obvious why the upstairs stayed warm.
The insulation had settled in some places. Other areas barely had enough coverage anymore. The attic itself was getting much hotter than it should’ve been.

The air conditioner never really had much of a chance.

We put a plan together
Every house is a little different, so we recommended what made sense for this one.
Our crew:
• Topped off the attic insulation to approximately 19 inches (R-49).
• Fixed the thin and compressed areas that had been disturbed over the years.
• Installed three solar attic fans to improve attic ventilation.
• Reduced the amount of heat building up above the living space.n schedule.


Financing also helped make the project fit the family’s budget, which was important to them.

The review said it better than I could
When we finished, the upstairs started holding the temperature they had been trying to get for the last couple of years.

The AC wasn’t running nearly as hard anymore.
That was the goal from the beginning.
A few days later Kul left us a review.
“Amazing job by everyone at Koala Insulation. From start to finish, it was a smooth process and we are very impressed with the work and service. We highly recommend.”

I always like reading those after the dust settles.
Sometimes the attic gets overlooked
Replacing an air conditioner makes sense if the equipment has failed.
But if the attic is holding onto all that heat, even a brand-new system can end up working overtime.

That’s exactly what was happening here.
The attic needed attention just as much as the AC did.

If you’ve noticed certain rooms staying warmer than the rest of your house, it might be time to look above the ceiling instead of replacing equipment again.
