Maximizing Comfort with R38 Fiberglass Insulation Upgrade in Clovis, CA

Juling reached out to us because her home in Clovis was struggling to maintain a stable indoor temperature. Her air conditioner was running non-stop in the summer, yet the house remained warm, leading to rising energy bills. After inspecting her attic, we found only 3 inches of old cellulose insulation—well below the recommended level. This inadequate insulation was allowing heat to seep into the home during summer and escape during winter, making her HVAC system work overtime.

To resolve this, we first air-sealed all major leakage points, including gaps around plumbing, wiring, and HVAC registers, using closed-cell foam. This step is crucial in preventing unwanted airflow between the attic and living spaces. Once the attic was properly sealed, we installed high-quality blown-in fiberglass insulation, bringing the attic up to an R38 level, which meets Energy Star recommendations for optimal efficiency.

Thanks to this insulation upgrade, Juling’s home will now maintain a more consistent temperature throughout the year, leading to lower heating and cooling costs and a significantly improved level of comfort.
