Fresh Air In
Open a few windows 2–6 inches. The fan pulls cool outdoor air through living spaces, replacing hot, stale indoor air with fresh air in minutes.
- Creates a gentle, comfortable breeze
- Lowers indoor temps without compressor use

QuietCool Whole-House Fans
QuietCool Whole-House Fan Installation in Anaheim
Bring in cool outdoor air, flush out heat, and give your AC a break. A QuietCool whole-house fan rapidly pulls fresh air through open windows and exhausts hot, stale air through the attic—delivering a fast cooldown, cleaner indoor air, and lower energy use in our Southern California climate.

How a QuietCool Fan Works
Hot Air Out
The remote-mounted fan pulls air into the attic and out through existing attic vents, flushing trapped heat and helping the home & ductwork start cooler the next day.
- Reduces attic heat that radiates into rooms
- Helps AC start cycles with cooler return temps
Best Times to Run in Anaheim
Use during the **evening, night, and early morning** when outdoor air is cooler than indoor air (typically spring, summer nights, and fall). Many homeowners run on low to refresh air daily, then a short burst on high for rapid cooldown.
- Open 2–3 windows in occupied rooms before starting
- Close fireplace dampers & isolate garage doors for safety
- Adjust speeds for comfort, sound, and airflow
Quick Sizing & Venting Guide
Right size = right results. We size by floor area, layout, and local temperatures, then verify attic venting so the system can breathe.
| Home Size (sq ft) | Rule-of-Thumb CFM* | Typical Window Openings | Attic Venting (NFA)** |
|---|---|---|---|
| 1,000–1,500 | ~2,000–4,000 CFM | 2–3 windows partially open | ~3–6 sq ft NFA |
| 1,600–2,200 | ~3,200–6,000 CFM | 3–4 windows partially open | ~5–8 sq ft NFA |
| 2,300–3,000+ | ~4,600–9,000+ CFM | 4+ windows or multi-zone | ~7–12+ sq ft NFA |
*Common design target is about 2.0–3.0 CFM per sq ft; layout, stories, and climate may shift sizing. **NFA = net free attic vent area; a common guideline is ~1 sq ft per ~750 CFM. We verify onsite.

Our Installation Process
1
Home Walkthrough & Sizing
We confirm square footage, layout, attic conditions, and existing venting to choose the right fan size(s) and grille locations.
2
Prep & Layout
Mark grille opening(s), verify framing clearances, and plan a short, straight duct path for quiet, efficient airflow.
3
Mount & Duct
Install vibration-isolated fan in the attic, connect insulated duct, and fit the low-profile ceiling grille with a clean finish.
4
Electrical & Controls
Wire to dedicated switch/timer per code and label controls to remind users to open windows before operation.
5
Commissioning & Walkthrough
Run test at each speed, check for smooth airflow and sound, review usage tips, and confirm attic venting is adequate.
Cost, Savings & Value
- Uses a fraction of AC energy; many homeowners report reduced AC runtime during evenings and shoulder seasons.
- Helps bedrooms cool quickly after sunset; improves sleep comfort on hot days.
- May qualify for local incentives/financing; we’ll advise on current programs.
Actual savings vary by weather, house design, and how you operate the system.
Safety & Best Practices
- Open windows before starting to prevent excessive negative pressure
- Close dampers on fireplaces; isolate garage air from the living space
- Do not operate during poor outdoor air conditions (smoke, heavy smog)
Maintenance
- Annual check of grille, duct connections, and attic vents
- Wipe grille; ensure clear soffit/ridge vents for airflow
- Ask about adding to your Freedom Comfort Club tune-ups
QuietCool vs. AC — How They Work Together
| Feature | QuietCool Fan | Air Conditioner |
|---|---|---|
| Primary Purpose | Bring in cool outdoor air & exhaust heat | Cool & dehumidify indoor air mechanically |
| Best Time to Use | Evenings/nights/mornings in Anaheim | Hot daytime hours & high-humidity periods |
| Energy Use | Low (fan motor only) | Higher (compressor & blower) |
| IAQ Impact | Fresh air exchange; removes indoor odors | Recirculates indoor air; filters particulates |
Warranty
Manufacturer warranty on the fan assembly plus our workmanship warranty on installation. Documentation provided at completion.
Code & Permitting
We follow local codes for electrical and ventilation. Some jurisdictions require permits; we’ll advise and handle as needed.
QuietCool — Frequently Asked Questions
Will a QuietCool replace my AC?
It’s a powerful complement, not a full replacement. Use the fan when outdoor air is cooler to reduce AC usage; use AC during hot daytime or high humidity.
Is it really quiet?
Yes. The motor mounts in the attic with insulated duct to the grille, so sound at the grille is a soft whoosh—much quieter than traditional whole-house fans.
How long does installation take?
Most homes are completed in a single visit. Multi-zone systems or attic access challenges can add time; we’ll provide a clear schedule.
What if my attic venting is insufficient?
We’ll measure net free area (NFA). If vents are lacking, we can add ridge, gable, or roof vents so the system can breathe properly.
Can you install with spray foam or sealed attics?
Sealed attics require special design or are not recommended for standard whole-house fans. We’ll evaluate and propose the right solution.
