Running your air conditioner all summer long — only to still have to deal with parts of your home still hot and stuffy — is frustrating and expensive. Many Naperville and Chicagoland homeowners assume their “failing” AC is the problem, but the real culprit is often hiding behind the walls and above the ceiling: old or underperforming insulation.
At ARC Insulation, we’ve helped hundreds of local homeowners solve summer comfort issues with insulation replacement and air sealing. If your insulation is outdated, damaged, or has settled over time, upgrading it can transform your home into a cool, energy-efficient haven this summer… and also keep it warm when winter returns.
Why Homes Struggle to Stay Cool in Chicagoland
Our region is known for hot, humid summers and wet, cold winters — extreme swings that put a lot of pressure on your home’s structure as well as its heating and cooling systems. Without proper insulation and air sealing, cool air escapes during the summer and hot, humid air sneaks in.
Over time, insulation can settle, compress, or lose effectiveness, especially in older homes. This means your AC works harder, your energy bills rise, and you still don’t get the comfort you deserve.
How Insulation Replacement Keeps Homes Cooler
1. Keeps Cool Air from Escaping
When insulation is performing at its best, it forms a barrier that prevents the conditioned air inside your home from escaping. This means you maximize the cool air from your AC, without having to keep it running 24/7.
2. Blocks Heat from Entering
Good insulation works both ways — it prevents hot outdoor air from infiltrating your home, reducing the strain on your air conditioner.
3. Works Hand-in-Hand with Air Sealing
If your home is drafty or has air leaks, insulation replacement combined with professional air sealing can eliminate these gaps, creating an even more efficient thermal envelope.
Signs Your Insulation May Need Replacing
- Uneven temperatures between rooms or floors
- AC runs constantly, but still struggles to keep the house cool
- Higher-than-normal or continuously rising summer energy bills
- Drafty areas near windows, doors, or attic access points
- Sounds carry easily between rooms (poor soundproofing is a sign of settled or thin insulation)
If you notice any of these signs, it’s time to have your home evaluated by a building science and insulation expert.
