San Jose’s Mediterranean climate treats homeowners to warm days, breezy evenings, and ever-rising energy bills. A properly sized whole house fan can slash cooling costs by up to 90 percent, purging trapped heat in minutes and letting evening air do the heavy lifting. CountBricks brings this technology to life with AI-driven estimating, voice-powered job site data capture, and seamless residential construction execution.
Our cloud platform records a real-time conversation—on site or over the phone—turning your priorities into a structured scope within seconds. No clipboards. No delays.
The scope feeds directly into CountBricks.com/services where live material pricing and regional labor rates generate a line-item estimate for your whole house fan San Jose project before we leave your driveway.
If you have existing plans, upload them for an automated attic measurement. Our AI highlights joist bays, electrical runs, and roof vent locations to confirm proper fan placement and CFM sizing.
Electronically sign your quote, approve the final materials list, and lock in a build date—all without printing a single sheet of paper. Transparency is baked in; you see exactly what we see.
CountBricks engineers calculate CFM by multiplying conditioned floor area by 2.5 to 3.0 for San Jose’s climate zone. A 2,000 sq ft home typically lands between 5,000-6,000 CFM. We then confirm adequate attic venting to exhaust that airflow.
• Square footage and ceiling heights
• Existing attic vent square inches
• Typical evening temperature drop
• Noise tolerance and fan speed preferences
Our two-person crew arrives with pre-cut framing materials, fire-rated gaskets, and the pre-wired fan assembly. A standard retrofit takes four to six hours.
1. Protect living areas with sealed plastic sheeting
2. Cut the ceiling opening and reinforce the joist bay
3. Position the fan, dampers, and insulated cover
4. Run dedicated electrical to a smart wall switch or Wi-Fi controller
5. Balance attic ventilation to maintain warranty compliance
6. Perform a 10-point airflow and sound test documented in the CountBricks field app

No. It complements AC by pre-cooling the home each evening, letting you delay or avoid compressor use.
Not with CountBricks. We include a MERV-rated filter box on every unit to capture pollen, ash, and valley dust.
Probably. We verify R-value during the site inspection and offer blown-in top-offs through CountBricks.com/services if needed.

1. Evening indoor temperature dropped from 82 °F to 73 °F within 25 minutes of first run
2. July utility bill fell by 38 percent compared to previous year
3. Attic humidity normalized, reducing roof deck moisture risk
“The process was unbelievably smooth. I approved the quote on my phone during lunch, and the crew was done before dinner the next day. CountBricks’ portal even showed me airflow test numbers in real time.”
• Open multiple downstairs windows 3-4 inches to balance airflow and prevent back-drafting gas appliances
• Run the fan only when outside air is at least 5 °F cooler than indoors for optimal efficiency
• Clean the grill and filter every spring to maintain rated CFM and keep sound levels low
• Pair with a smart thermostat so your AC and fan never run simultaneously
