How to Lower Your Summer AC Bills in the Central Valley

Central Valley summers are brutal on both your comfort and your electric bill. The good news: the biggest savings don't come from a new AC — they come from stopping heat from getting into your home in the first place. Here's where to focus, in order of impact.

Start with the attic. An under-insulated attic is the single largest source of summer heat gain. Getting to R-38 or higher with even, gap-free blown-in insulation is the highest-ROI upgrade for most homes here.

Air seal before you insulate. Sealing top plates and penetrations stops your cooled air from leaking into a 150°F attic. It's cheap and it multiplies the value of your insulation.

Add a radiant barrier. In our intense sun, a reflective barrier under the roof deck bounces radiant heat back out before it ever loads your attic — a strong complement to insulation.

Run a whole-house fan in the evenings. A QuietCool pulls cool evening air through the house and flushes hot attic air out, dramatically reducing AC runtime during the coolest hours.

Do these together and most Central Valley homeowners see a real, measurable drop in summer cooling costs. We can assess which combination makes the most sense for your home, free.
