If you're researching an AirScape whole house fan, you've likely noticed they offer multiple models across their Sierra and Ventura product lines, each with different CFM ratings, noise levels, and price points.
With over 23 years of selling whole house ventilation systems, we've helped thousands of customers at Whole House Fan find the right fit for their homes. AirScape consistently ranks among the brands our customers ask about most, and for good reason: their fans deliver strong airflow with relatively quiet operation compared to older belt-driven models.
This guide breaks down five AirScape whole house fan options worth considering. You'll get specs, real-world pricing, and noise data so you can compare models side by side and make a confident purchase decision.
1. AirScape Sierra 3200-XR
The Sierra 3200-XR represents AirScape's most popular mid-range option for homeowners with medium to large spaces needing powerful airflow without excessive noise. This model delivers 3,200 CFM on high speed, which translates to cooling coverage for homes up to 2,500 square feet in most climates.
Key specs and coverage
Your Sierra 3200-XR pulls 3,200 CFM at its highest setting, with a two-speed control that lets you drop down to 2,200 CFM when you need less ventilation. This airscape whole house fan weighs 33 pounds and measures 24 inches wide by 16 inches tall, making it compact enough to fit in most ceiling joist configurations. The unit draws 2.9 amps on high, which keeps your electricity costs minimal compared to running central air conditioning.
Noise and comfort features
AirScape rates the 3200-XR at 52 decibels on high speed and 48 decibels on low, roughly equivalent to a quiet conversation in your living room. The direct-drive motor eliminates belt squeal and reduces vibration transfer, while the suspended mounting system isolates operational noise from your ceiling joists.
Install requirements and attic venting needs
You'll need at least 8 square feet of attic venting to handle the 3,200 CFM output without creating back pressure. Most installers recommend 10 to 12 square feet for optimal performance. The unit requires a standard 120V outlet and fits between 16-inch on-center joists, though you can modify framing if necessary.
Who this model fits best
This model works best if you own a two-story home between 1,800 and 2,500 square feet in a climate where evening temperatures drop into the 60s or low 70s. Single-story ranch homes up to 2,000 square feet also see excellent results with this CFM rating.
Price range and what you get
You'll typically pay $800 to $950 for the Sierra 3200-XR depending on your retailer and current promotions. Your purchase includes the fan unit, mounting hardware, and a basic two-speed control switch.
The 3200-XR offers the best balance of airflow, noise, and price for most medium-sized homes.
2. AirScape Sierra 1700
The Sierra 1700 serves as AirScape's entry-level option for homeowners with smaller spaces who still want quality construction and American manufacturing. This airscape whole house fan moves 1,700 CFM on high speed, making it ideal for compact homes, condos, or single-story properties up to 1,200 square feet.
Key specs and coverage
Your Sierra 1700 delivers 1,700 CFM at maximum speed with a two-speed motor that reduces to approximately 1,200 CFM on the lower setting. The unit weighs 28 pounds and measures 20 inches wide by 14 inches tall, fitting easily into standard ceiling joist spacing. Power consumption sits at 1.8 amps on high, which translates to pennies per hour of operation.
Noise and comfort features
AirScape rates this model at 48 decibels on high speed and 45 decibels on low, quieter than most refrigerators. The direct-drive motor design eliminates belt noise entirely, while rubber isolation mounts prevent vibration transmission through your ceiling structure.
Install requirements and attic venting needs
You'll need minimum 5 square feet of attic venting for proper exhaust, though 6 to 8 square feet works better for sustained use. The fan operates on standard 120V power and installs between 16-inch on-center joists without structural modifications in most cases.
Who this model fits best
This model works perfectly if you own a small home or condo under 1,200 square feet or want to cool specific zones rather than your entire house.
The Sierra 1700 gives smaller homeowners the same quality and efficiency as larger AirScape models.
Price range and what you get
Expect to pay $600 to $750 for the Sierra 1700, which includes the fan assembly, mounting brackets, and two-speed wall switch.
3. AirScape Sierra 3400
The Sierra 3400 targets homeowners with larger properties who need maximum cooling capacity while maintaining reasonable noise levels. This airscape whole house fan pushes 3,400 CFM on high speed, providing coverage for homes up to 2,800 square feet in most climate zones.
Key specs and coverage
Your Sierra 3400 moves 3,400 CFM at full power with a two-speed control dropping to roughly 2,400 CFM on the lower setting. The unit weighs 35 pounds and spans 26 inches wide by 16 inches tall, requiring standard ceiling joist spacing. This fan draws 3.1 amps on high, keeping your utility bills low despite the higher airflow.
Noise and comfort features
AirScape rates the 3400 at 53 decibels on high and 49 decibels on low, comparable to background conversation noise. The direct-drive motor eliminates belt maintenance, while vibration-dampening mounts reduce ceiling noise transfer.
Install requirements and attic venting needs

Who this model fits best
This model suits homeowners with 2,200 to 2,800 square foot properties in regions where evening temperatures drop enough for effective ventilation cooling.
The Sierra 3400 delivers top-tier airflow for larger homes without jumping to commercial-grade noise levels.
Price range and what you get
Expect to pay $900 to $1,050 for the Sierra 3400, which includes the fan unit, mounting hardware, and two-speed switch.
4. AirScape Ventura V3400G
The Ventura V3400G represents AirScape's dedicated garage cooling solution with 3,400 CFM capacity designed specifically for workshop and garage installations. This airscape whole house fan uses a wall-mounted design rather than ceiling installation, making it perfect for spaces where ceiling access proves difficult or where you need targeted ventilation.
Key specs and coverage
Your Ventura V3400G delivers 3,400 CFM at maximum speed through a single-speed motor optimized for consistent airflow. The unit weighs 42 pounds and measures 30 inches in diameter, mounting directly to an exterior wall or garage door opening. Power draw sits at 3.2 amps, keeping operational costs minimal during extended use.
Noise and comfort features
AirScape rates this garage model at 55 decibels, slightly louder than ceiling-mounted units due to the direct wall mounting. The aluminum blade construction reduces vibration, while the weather-resistant housing handles temperature fluctuations in uninsulated spaces.
Install requirements and attic venting needs
You'll mount this fan through an exterior wall or garage door panel, requiring a 30-inch circular opening. Installation needs access to 120V power near the mounting location.
Who this model fits best
This model works perfectly if you need to cool a detached garage, workshop, or storage building rather than your main living space.
Price range and what you get
Expect to pay $950 to $1,100 for the Ventura V3400G, including the fan unit, wall mounting bracket, and external weather cover.
The Ventura V3400G solves garage cooling without requiring attic access or ceiling modifications.

Who this model fits best
This model suits homeowners with 3,000 to 4,000 square foot properties or multi-story homes where strong airflow matters more than absolute quiet operation.
The Sierra 5300 delivers commercial-grade airflow for residential applications without requiring special electrical circuits.
Price range and what you get
Expect to pay $1,100 to $1,300 for the Sierra 5300, including the fan assembly, heavy-duty mounting hardware, and two-speed control switch.
Next steps before you buy
Your airscape whole house fan selection should match your home's square footage and your climate conditions for maximum efficiency. Take time to measure your existing attic venting before ordering, since inadequate exhaust space reduces performance and increases noise levels regardless of which model you choose. Most installers recommend calculating two square feet of venting per 1,000 CFM as a safe baseline for consistent operation.
Check your local building codes for whole house fan ventilation requirements, as some jurisdictions require permits or inspections for installations. Most AirScape models qualify for DIY installation if you feel comfortable working with basic electrical wiring and ceiling modifications. Professional installation typically adds $300 to $600 to your total cost depending on your region and project complexity.
