5 Home Depot Whole House Fan Models: Specs, Prices Compared
If you're browsing Home Depot whole house fan options, you've probably noticed the range of CFM ratings, brand names, and price tags. Making sense of these specs matters because the wrong fan size wastes money, either on a unit that can't cool your home or one that's overkill for your square footage.
This guide compares five whole house fan models sold at Home Depot, breaking down their airflow capacity, noise levels, and pricing. You'll get the practical details needed to narrow your choices before heading to the store or placing an online order.
At Whole House Fan, we've spent over two decades helping homeowners find the right cooling solution. That experience means we can offer an unbiased look at these products, what works, what doesn't, and how each model stacks up against modern alternatives.
1. QuietCool QC CL-4700 advanced whole house fan
This QuietCool model sits in the mid-range capacity tier, offering 4,700 CFM that works for homes between 1,800 and 2,350 square feet. You'll find it positioned as a step up from basic whole house fans, with features aimed at reducing noise and simplifying installation.
Airflow, coverage, and sizing basics
The 4,700 CFM rating handles most two-story homes comfortably, pulling enough air to create 15 to 20 air changes per hour when you crack open a few windows. Your coverage depends on ceiling height and floor plan layout, but this capacity typically works for homes up to 2,350 square feet with standard 8-foot ceilings. Homes with vaulted ceilings or open floor plans might need a higher CFM model to maintain effective cooling.
Noise level and comfort factors
QuietCool rates this fan at 52 decibels on the highest speed, which lands somewhere between normal conversation and background music. The company uses a damper box design to reduce vibration noise, though you'll still hear the airflow itself. Lower speed settings drop the noise level, but they also reduce the cooling power you're getting from the unit.
Expect noticeable fan noise during operation, though it's quieter than older direct-drive models.
Controls, speeds, and day-to-day use
You get a two-speed wall switch that lets you adjust airflow based on outdoor temperature and how quickly you want to cool your home. The higher setting pulls maximum CFM for rapid cooling during evening hours, while the lower speed works for overnight use when you want gentler airflow. Some installations add a timer, but that's a separate purchase.
Installation fit, attic requirements, and venting needs
This unit needs 24 inches of joist space and at least 30 inches of vertical clearance in your attic. Your attic requires 1 square foot of net free ventilation for every 750 CFM, which means you need roughly 6.3 square feet of gable vents, ridge vents, or turbine vents. Most older homes need vent upgrades before this fan works properly.
Home Depot price range and what's included
The Home Depot whole house fan listing shows this model between $599 and $699 depending on seasonal sales. Your purchase includes the fan unit, damper box, and mounting hardware, but you'll buy the wall switch separately. [Professional installation](https://www.wholehousefan.com/blogs/wholehousefans/whole-house-fan-installation) adds $300 to $500 to your total cost.
2. QA-Deluxe 6500 CFM energy efficient whole house fan QA-Deluxe 6500 R2
The QA-Deluxe model pushes 6,500 CFM, making it suitable for larger homes that need stronger cooling capacity than entry-level units provide. This fan targets homeowners with square footage that exceeds what smaller models can handle effectively.
Airflow, coverage, and sizing basics
You get 6,500 CFM of airflow that covers homes up to 3,250 square feet with standard ceiling heights. The higher CFM rating creates faster air exchanges, which means your home cools down in 20 to 30 minutes instead of an hour or more with weaker fans.
Noise level and comfort factors
This unit operates at higher noise levels than the QuietCool model, typically around 60 to 65 decibels on full speed. Your comfort depends on whether you value maximum cooling power over quiet operation.
Controls, speeds, and day-to-day use
The two-speed controller lets you dial back airflow when outdoor temperatures drop or when you want less noise during sleep hours.
Installation fit, attic requirements, and venting needs
Your attic needs approximately 8.7 square feet of net free ventilation to support this home depot whole house fan model's capacity. Most installations require additional venting beyond what existing homes provide.
Insufficient attic ventilation causes hot air buildup that cancels out your cooling gains.
Home Depot price range and what's included
Pricing ranges from $450 to $550 at Home Depot, with the fan housing and basic mounting hardware included in your purchase.
3. QuietCool classic QC CL-7000 RF advanced whole house fan
This QuietCool model delivers 7,000 CFM with remote control operation, targeting homeowners who need high-capacity cooling without getting up to adjust settings. Your investment gets you one of Home Depot's stronger whole house fan options with modern control features.
Airflow, coverage, and sizing basics
The 7,000 CFM capacity handles homes up to 3,500 square feet, making it suitable for larger two-story houses or homes with open floor plans. You'll see cooling results in 15 to 25 minutes during typical summer evenings.
Noise level and comfort factors
QuietCool rates this unit at 53 decibels, which puts it slightly above their 4,700 CFM model despite moving significantly more air. Your noise experience depends on attic acoustics and installation quality.
Controls, speeds, and day-to-day use
The RF remote control lets you adjust two speed settings from anywhere in your home, eliminating trips to the wall switch. Battery life typically lasts six months to a year before replacement.
Remote control convenience works well for bedrooms where you want to adjust airflow without leaving bed.
Installation fit, attic requirements, and venting needs
Your attic needs roughly 9.3 square feet of net free ventilation area to support this home depot whole house fan model's output.
Home Depot price range and what's included
Expect pricing between $749 and $849, with the remote control included in your purchase.
4. Master Flow 4500 CFM 24 in. direct drive whole house fan with shutter WHFS24M
This Master Flow unit represents the budget-conscious option among Home Depot's whole house fan selection, offering 4,500 CFM in a traditional direct-drive design. You'll find basic functionality here without the acoustic dampening features that higher-priced models include.
Airflow, coverage, and sizing basics
The 4,500 CFM rating covers homes up to 2,250 square feet, making it suitable for smaller two-story houses or single-story layouts with standard ceiling heights. Your cooling time runs between 25 and 40 minutes depending on how many windows you open and outdoor temperature conditions.
Noise level and comfort factors
Direct-drive construction means you'll experience louder operation than belt-driven or damper-box models, typically running at 65 to 70 decibels on full speed. This noise level compares to a running vacuum cleaner or busy street traffic.
Controls, speeds, and day-to-day use
You get single-speed operation with a basic on-off switch, which limits your ability to fine-tune airflow for different cooling needs throughout the evening.
Installation fit, attic requirements, and venting needs
The 24-inch diameter requires standard joist spacing, and you need 6 square feet of attic ventilation to support the CFM output. Built-in shutters close automatically when you turn off this home depot whole house fan model.
Direct-drive fans cost less upfront but generate more operational noise than modern alternatives.
Home Depot price range and what's included
Pricing sits between $299 and $349, with the fan, shutter assembly, and mounting hardware included in your purchase.
5. Air Vent 3500 CFM automatic shutter whole house fan WH242MLX
The Air Vent model provides the lowest CFM rating among these five options, delivering 3,500 CFM for smaller homes or budget-limited projects. This unit represents the most affordable home depot whole house fan choice, trading cooling capacity for upfront savings.
Airflow, coverage, and sizing basics
Your 3,500 CFM capacity works for homes up to 1,750 square feet, making it suitable for single-story houses or small two-story layouts. Cooling times run longer than higher-capacity models, typically taking 40 to 60 minutes to flush hot air from your living spaces during summer evenings.
Noise level and comfort factors
Expect operational noise between 60 and 65 decibels with this traditional direct-drive design. The lack of sound dampening features means you'll hear motor noise alongside airflow, which can disrupt sleep or quiet activities.
Controls, speeds, and day-to-day use
Single-speed operation limits your flexibility, giving you an on-off switch without variable airflow control. Automatic shutters close when you power down the unit, preventing heat loss during winter months.
Installation fit, attic requirements, and venting needs
The 24-inch mounting diameter fits standard joist spacing, and you need roughly 4.7 square feet of attic ventilation to support this model's output.
Lower CFM requirements mean less extensive attic vent modifications for older homes.
Home Depot price range and what's included
Pricing ranges from $249 to $299, making this the most economical option with fan housing, shutters, and basic mounting hardware included.
Final take
These five home depot whole house fan models span capacities from 3,500 to 7,000 CFM, each targeting different home sizes and budgets. Your decision comes down to matching CFM capacity to your square footage, balancing noise levels against cooling power, and deciding whether features like remote control or variable speeds justify higher upfront costs.
The CFM-to-square-footage ratio determines whether a fan works effectively or runs constantly without delivering results. Undersized units struggle to cool your home, while oversized models waste energy and create unnecessary noise. Price differences reflect acoustic engineering, control sophistication, and build quality beyond just raw airflow numbers.
Modern alternatives offer advantages these traditional units can't match.
