A whole house fan is a powerful ventilation unit installed in your ceiling — typically in an upstairs hallway. It connects to your attic. When you open windows and run the fan, it pulls cool outdoor air in through every room and pushes hot indoor and attic air out through your roof vents. On a typical California evening when outdoor temperatures drop into the 60s or low 70s, the fan can bring your home down to that temperature in 10–15 minutes.

An attic fan only ventilates the attic — it has no effect on your living space temperature. A whole house fan moves air through every room in your home and then out through the attic. It moves 10–20× more air than a typical attic fan and actually cools the spaces where you live. They solve different problems.

Modern whole house fans from QuietCool and AirScape run at 35–45 decibels on low speed — roughly the same as a quiet conversation, quieter than most ceiling fans, and much quieter than old whole house fans from the 1970s. High speed is louder (55–65 dB), but most homeowners use low or medium for evening cooling. We bring decibel specifications to every assessment.

No — during active smoke events, keep the fan off and windows closed. A whole house fan pulls outdoor air in, so you don't want to use it when air quality is poor. On clear-air days, which is the majority of the year in most California markets, it's excellent. We cover this thoroughly during the installation walkthrough.

Yes — they're designed to complement each other, not compete. Use your AC during the hottest midday hours when outdoor air is too warm to use the fan. Switch to the fan in the evening when outdoor temperatures drop. Most homeowners find they run their AC far less once the fan is installed.

Yes — and it's actually an ideal pairing. Your solar panels produce peak power during the day. Your whole house fan runs in the evening when the sun is down and your solar production has stopped. There's no technical conflict, and the combination is one of the most efficient setups available for a California home.

Yes — two-story homes are one of the best applications. Hot air rises and collects on the upper floor, making upstairs bedrooms miserable at night. A whole house fan installed in the top-floor ceiling draws that hot air up and out, pulling cooler air up from the ground floor. This is one of the most common problems we're asked to solve.

A quality QuietCool or AirScape whole house fan should last 15–25 years with minimal maintenance. There are no filters to replace, no refrigerant to recharge, and no compressor to fail. The motor is the primary mechanical component and is built for continuous seasonal use.

Exterior solar screens are installed on the outside of your window frames using a tightly woven mesh fabric — typically 80% or 90% shade factor. They intercept solar radiation before it passes through the glass and converts to indoor heat. Because the energy is stopped at the source — outside the glass — the heat never enters your home and your AC never has to remove it. This is the most efficient place to stop solar heat gain.

Interior blinds and shades stop light — but solar energy has already passed through the glass and is already inside your home. You're trapping heat between the blind and the window, not stopping it. Window film performs better than blinds but still allows some heat through the glass. Exterior screens stop solar energy at the outside surface, before it converts to indoor heat. They're significantly more effective at reducing actual heat gain — because they stop it before it enters, not after.

They reduce incoming light — that's part of how they reduce heat. However, on an 80% screen, most homeowners retain clear outward visibility and the room gets slightly dimmer, not dark. On a 90% screen, the reduction is more noticeable. We bring fabric samples to your assessment so you can hold them against your own windows before deciding.

Yes. Solar screens are installed on the exterior frame and don't interfere with window operation. You can open and close your windows normally.

Yes — sliding glass doors are one of the highest-impact applications because they represent a large glass area with direct sun exposure. We custom-fabricate screens for sliding door openings including oversized panels.

Yes. They install with standard screen clips and can be removed and stored seasonally. Many California homeowners leave them year-round since winters are mild, but seasonal removal is straightforward if preferred.

Quality solar screen mesh and aluminum frames are rated for 10–15 years of exterior use in California climates. The mesh may need re-stretching or replacement after many years if physically damaged, but frames are typically reusable.

From outside, solar-screened windows have a clean, dark mesh appearance — similar to a standard window screen but darker and more uniform. Most homeowners find they look professional and intentional rather than modified. They don't read as reflective or makeshift the way some window film treatments do.

No — we quote them together and separately. Many homeowners start with one product and add the other later. We'll give you an honest recommendation during your assessment based on your specific home, your hottest problems, and your budget.

The combined system addresses both sides of the cooling problem — heat entering through windows (screens) and heat trapped inside the home (fan). Homeowners who do both typically see 40–70% reductions in AC runtime during shoulder seasons and report that their homes are comfortable at night in ways they couldn't achieve with the AC alone.

Usually yes. A combined installation typically takes 6–8 hours. We schedule a full installation day and handle both products in a single visit — one assessment, one crew, one day.

Installed cost varies based on the model, your home's size, and whether any attic ventilation work is needed. We give you a complete written quote during a free in-home assessment. We don't quote blind over the phone because every home is different.

Cost depends on the number of windows, their sizes, and the fabric specification. We quote per screen during your free assessment after measuring each window.

Whole house fan installation typically takes 4–6 hours. Solar screen installation for a whole house (8–15 windows) takes 2–4 hours. Both together usually take 6–8 hours. Most jobs are completed in a single day.

Whole house fan installation in most California cities — including San Jose — requires a permit due to the electrical connection and attic penetration. We handle the permit process for you when required. It's included in your written quote with no hidden fees. Solar screen installation typically does not require a permit.

We warranty our workmanship on every installation. Equipment warranties vary by brand and model — QuietCool and AirScape both offer manufacturer warranties we explain during your assessment.

We typically schedule free in-home assessments within 2–5 business days. We send an email confirmation and follow up within 1 business hour (Monday–Saturday, 8 AM–6 PM).
