Almaden Valley sits in a sun-exposed pocket of South San Jose with some of the longest afternoon sun exposure in the Bay Area. Many homes here were built in the 1970s through 1990s — solid construction, but designed before energy costs became what they are now. West-facing windows on the back of the house take direct afternoon sun from 2 PM until sunset. Two-story floor plans trap heat upstairs. And the valley geography means evenings cool down beautifully — but only if your home has a way to let that cool air in and push the day's heat out.
This is exactly the problem a whole house fan and exterior solar screens solve together.
Problem 1 — Heat getting in through west-facing windows.
Solar screens block 80–90% of that heat before it ever hits the glass. The difference in a west-facing room on a 95°F afternoon is 10–15°F — without changing anything else.
Problem 2 — Heat trapped inside after sunset.
Your walls, furniture, and attic store the day's heat and release it slowly into the evening. A whole house fan flushes all of that out in 10–15 minutes when the outside air cools down — usually by 8–9 PM in Almaden.
Most Almaden homeowners see their AC runtime drop significantly in the months before and after peak summer (April–June and September–October), and their upstairs bedrooms become genuinely comfortable at night.
We install QuietCool and AirScape whole house fans, sized for your specific square footage and floor plan. Most Almaden homes (1,800–3,200 sq ft, two stories) use the QuietCool ES-4700 or ES-7000 series — powerful enough to exchange the full home air volume every 3–4 minutes on high speed, and quiet enough to sleep through on low.
We install exterior solar screens on the windows that matter most — typically south- and west-facing windows, which take the most direct sun in Almaden homes. Screens are custom-measured and built for your specific window dimensions. Installed on the outside of the frame, removable seasonally if preferred.
Most of our Almaden customers do both. We assess the whole home during your free visit and recommend where each upgrade will make the biggest difference for your specific floor plan and sun exposure pattern.

Yes — Almaden is one of the better climates in the Bay Area for whole house fan performance. Afternoons regularly reach 90–100°F in summer, but evenings typically cool into the 60s by 8–9 PM. That temperature swing is exactly what makes a whole house fan effective. The bigger the swing between daytime high and nighttime low, the better the results.
San Jose building code generally requires a permit for whole house fan installation, as it involves an electrical connection and attic penetration. We handle the permit process for you when required — it's included in your written quote, no hidden fees.
Homes from that era in Almaden Valley commonly have adequate eave and ridge ventilation, but we always verify before installation. We calculate the required vent area for your specific fan model during your free assessment. If additional ventilation is needed, we include it in the quote.
Yes. Aluminum frame windows are actually one of the easier window types to work with for exterior screen installation. We custom-measure each window and fabricate the screen to fit.
