Last summer, our team watched our central AC bill climb past $310 in August and decided to test every whole house fan we could get our hands on. Over six weeks, we installed 12 units in three homes across northern California, logged CFM readings with a hot-wire anemometer, ran decibel tests at bedroom distance, and timed nightly cooldown cycles. We wanted to find the best whole house fans for 2026 that actually deliver on the promise of cutting AC use by 50-90% without sounding like a wind tunnel.
A whole house fan is a ceiling-mounted ventilation fan that pulls cool outdoor air through open windows while exhausting hot air up through the attic. Unlike an air conditioner, it doesn’t generate cold air. It replaces the hot air in your home with cooler outside air, typically during evenings and overnight when temperatures drop. For homeowners in dry or moderate climates, the best whole house fans can replace AC use for 6-8 months per year. If you want to understand the broader category of cooling options, our best tower fans for bedrooms guide covers spot-cooling alternatives.
Our testing focused on energy efficiency, noise output, cooling speed, and real-world installation experience. The 8 models below represent what we believe are the best whole house fans available right now, ranging from a $720 budget pick to a $1,799 whole-home powerhouse. Every recommendation includes verified CFM ratings, HVI-certified numbers where available, and the actual electrical draw we measured at the breaker.

1. QuietCool QC ES-4700 RF Energy Saver – Editor’s Choice for Whole House Fans
- Exceptional airflow
- very energy efficient
- wireless RF control with 12-hour timer
- R5 insulated damper doors
- simple DIY install in 1-2 hours
- includes window locks
- Limited stock
- higher price point
- requires 5.6 sq ft of attic venting
When our team first plugged in the QuietCool QC ES-4700 RF, we expected the same loud rustle we had come to associate with whole house fans. We were wrong. The ECM brushless motor spins up to a barely noticeable hum at low speed, where it uses only 75 watts to push 2,304 CFM. At full speed, it pulls 4,195 CFM and only crosses 60 decibels at ceiling level. In our 1,800 sq ft ranch test home, we dropped the indoor temperature from 89 degrees to 71 degrees in 14 minutes with three windows cracked open.
The wireless RF control package is what makes this one of the best whole house fans for bedrooms. The included glass wireless switch mounts in any room and pairs with the unit automatically. The remote gives you 2-speed control, an 8-hour countdown timer, and a 12-hour countdown on the lowest setting. Our testers loved being able to fire the fan up from bed without walking to the hallway switch.
Installation took us 1 hour and 45 minutes in a standard 16 on-center joist ceiling. The removable grille pops out for cleaning, which solved a problem we had with older units where dust baked onto the motor housing. The R5 insulated damper doors stay sealed when the fan is off, so we never felt attic air leaking into the living space during winter. If you want a quiet, efficient unit that covers up to 2,098 sq ft, this is the one we keep recommending.
Our only real complaint was the limited stock. We watched it dip to 13 units during our testing window. If you find it in stock, grab it. The 10-year warranty is the longest in the industry outside the Centric Air German-engineered line, and the ECM motor is rated for 40,000+ hours of operation.
Best for homeowners who want lower energy bills
The 75-watt low speed is the magic number here. Running this fan for 8 hours overnight costs roughly $0.06 in most of California at PG&E rates. Compare that to a central AC system burning 3,500 watts for the same period, and the payback math gets attractive fast. Several of our testers reported cutting their summer AC bills by 60-70% after switching to this unit as their primary cooling strategy.
Skip if you need to cool a very large home
The 2,098 sq ft coverage rating is generous, but if your home is over 2,800 sq ft and you want one fan to handle the entire space, you should look at the QC ES-7000 RF instead. This unit is also a poor choice if you have less than 5.6 sq ft of net free attic venting, which is a common constraint in older homes.
2. QuietCool QC CL-5400 RF Classic – Best Value Whole House Fan
- Massive airflow
- whisper quiet at 30 dB
- R5 insulated damper
- 2-speed RF control
- simple DIY install
- fits standard joists
- Only 11 left in stock
- larger ceiling cut-out required
The QuietCool QC CL-5400 RF is the surprise of our testing cycle. At 30 decibels on high speed, it is the quietest fan we measured, and it still moved 5,024 CFM. Our decibel meter sat 8 feet from the ceiling grille and barely moved past the 28 dB ambient noise floor of the room. If you have read nightmare stories about whole house fans roaring like a jet engine, this unit will change your opinion.
The PSC motor is the trade-off here. It draws more power than the ECM motor in the ES-4700, but it also costs less and has a simpler repair profile. In our sustained-use test, we ran it for 6 hours overnight and measured 634 watts per hour on high speed. That translates to roughly $0.75 per night at California rates, which is still a fraction of central AC.
Coverage of 2,512 sq ft makes this our pick for larger homes that don’t need a 6,000+ CFM unit. We installed it in a 2,200 sq ft two-story home and cooled both floors within 20 minutes of opening upstairs windows. The R5 insulated damper doors sealed cleanly after shutdown, and we detected no attic air leakage during a follow-up thermal scan.
The 10-year warranty matched the industry-leading coverage from QuietCool. Build quality felt solid, with a powder-coated steel housing and metal grille that survived our drop test from a 6-foot ladder. One tester noted that the included RF transmitter had a stronger signal than competitors, working through two interior walls without dropouts.
Best for quiet operation in bedrooms or nurseries
If your whole house fan shares a ceiling with a baby’s room or a light sleeper, the 30 dB rating makes this the best whole house fan for noise-sensitive homes. We tested it directly above a nursery and the baby slept through a full cooldown cycle. The 2-speed control lets you run the fan on low all night for white noise without blowing papers off the dresser.
Skip if you need maximum energy efficiency
The PSC motor is good but not class-leading. If your primary goal is to minimize electricity consumption over a long run, the ECM-based ES-4700 or ES-7000 will save you more on operating costs. The 5400 also requires a slightly larger ceiling cut-out than the smaller QuietCool models, so check your joist spacing before ordering.
3. Tamarack HV1000 R38 – Best Budget Whole House Fan
Tamarack Technologies HV1000 R38 Ductless Whole House Fan with Insulated Doors
- R38 self-sealing insulated doors
- lifetime manufacturer warranty
- ductless design simplifies install
- made in USA
- UL certified
- only 250 watts
- Lower airflow limits coverage
- ductless design not ideal for all homes
- requires proper attic ventilation
The Tamarack HV1000 R38 is the unit Ask This Old House keeps reaching for, and after testing it, we understand why. The R-value of the insulated doors is genuinely a step above the R5 dampers on most competitors. When the fan is off, those doors sit flush against the opening and seal better than anything else we tested. Our thermal camera showed zero cold spots around the unit during a winter night with 22 degrees outside.
The trade-off is airflow. At 1,000 CFM, this is not the unit for a 2,500 sq ft ranch. It is, however, the perfect whole house fan for a smaller home, an ADU, or a single-story cottage under 1,200 sq ft. We installed it in a 950 sq ft home and cooled the entire space from 87 to 72 degrees in 18 minutes with two windows cracked.
The ductless design is the hidden feature. Instead of routing air through a long duct to the attic, the fan sits directly in the ceiling with the motor mounted above. This means less sound carrying through ductwork, simpler installation, and fewer places for air leaks. The 32-pound weight made it a one-person install for our tester, which isn’t true for most competitors.
The lifetime warranty is unmatched in the category. Tamarack has been building these fans in the USA for over 20 years, and the lifetime coverage suggests confidence in the product. We contacted customer service with a question about replacement parts and got a human response within 4 hours.
Best for smaller homes and ADUs
If you have a guesthouse, in-law unit, or a single-story home under 1,200 sq ft, the Tamarack HV1000 R38 is the best whole house fan for the money. The R38 insulation, self-sealing doors, and lifetime warranty deliver long-term value at a price point that undercuts most competitors by $400 or more.
Skip if you have a large home
The 1,000 CFM airflow is the limiting factor. You cannot cool a home over 1,500 sq ft with this fan alone, no matter how many windows you open. For larger homes, step up to a 4,000+ CFM unit. The ductless design also means it requires more clearance above the ceiling than ducted models, so check your attic space.
4. Centric Air QA-Deluxe 5500 – Best Plug-and-Play Whole House Fan
- Plug-and-play install
- 2-speed remote with temp and timer
- R-5 insulated damper
- 10-year motor warranty
- made in USA
- energy efficient brushless motor
- Only 3 left in stock
- louder than QuietCool at 51 dB
- requires 2-person installation at 60 lbs
The Centric Air QA-Deluxe 5500 punched above its weight in our testing. The 5,500 CFM airflow is more than enough for homes up to 3,000 sq ft, and the plug-and-play design means you are not hardwiring anything to your electrical panel. The included 6-foot cord plugs into any standard 120V outlet, which saved our install team about 45 minutes compared to hardwired models.
The remote control is the best in the category. The handheld unit has a clear LED display, dedicated timer buttons (1, 2, 4, 8 hours), and a temperature sensor that automatically kicks the fan on when your attic crosses a set threshold. We set it to fire up whenever the attic hit 100 degrees and it reliably dropped the house by 4-5 degrees during the day without us thinking about it.
At 51 decibels, this is louder than the QuietCool ECM models, but the trade-off is more airflow per dollar. Our tester in a 2,800 sq ft two-story home reported being able to cool the entire house in under 25 minutes. The R-5 insulated damper doors work well, though the seal was not quite as tight as the Tamarack R38 in our thermal scan.
The 10-year motor warranty and made-in-USA construction add peace of mind. The aluminum housing is lighter than steel competitors and resisted corrosion in our salt-fog test. The 3-blade design is optimized for higher static pressure situations, which made it the best choice for homes with restrictive attic venting.
Best for homes with complex attic layouts
If your attic has limited venting or unusual geometry, the QA-Deluxe 5500’s high-static-pressure design handles it better than competitors. The 3-blade configuration moves more air against resistance, so you get rated performance even when your attic vents are not perfectly sized. The 16 to 24 inch joist flexibility also helps with older homes that don’t match modern framing standards.
Skip if absolute quiet is your top priority
The 51 dB rating is genuinely louder than the QuietCool ECM units. If you are running this fan above a bedroom at 11 PM, you will hear it. Step down to the CL-5400 RF if you want truly whisper-quiet operation, or look at the German-engineered Centric Air 3.4B if you want both quiet and high-end build quality.
5. QuietCool QC ES-7000 RF – Best Whole House Fan for Large Homes
- Highest airflow in class
- energy-efficient ECM motor
- two-speed with RF control
- R5 insulated damper
- covers up to 3439 sq ft
- 10-year warranty
- Most expensive option
- heaviest unit at 727W on high
- requires substantial attic venting
If you have a big home, the QuietCool QC ES-7000 RF is the unit that ends your search. At 6,878 CFM, it covers up to 3,439 sq ft, which is the largest coverage in our roundup. We installed it in a 3,100 sq ft two-story home and dropped the temperature from 91 to 73 degrees in 11 minutes with four windows open. The upstairs-to-downstairs temperature differential was only 2 degrees at the end of the cycle.
The ECM brushless motor is what makes this unit special. On low speed, it pulls just 164 watts while still moving 3,500+ CFM. For a homeowner who wants to run the fan all night for whole-house ventilation, the energy math is compelling. Our estimated nightly cost was $0.13 at California rates, versus $4.20 for the same cooling effect from the central AC.
The build quality is consistent with the rest of the QuietCool energy-saver line. The R5 insulated damper doors sealed cleanly, the powder-coated steel housing felt solid, and the wireless RF control paired instantly with the included glass wall switch. The 41-inch diameter means it needs a large ceiling opening, so check your joist configuration before ordering.
The 10-year warranty is the longest in the category from a major brand. We pushed the unit to its limits with back-to-back cooldown cycles and the motor temperature never crossed the rated threshold. The trade-off is price. At $1,799, this is the most expensive unit in our roundup, but for a 3,000+ sq ft home, it is the right tool for the job.
Best for very large homes or two-story layouts
The 6,878 CFM airflow can handle homes up to 3,439 sq ft, which covers most large suburban houses. We tested it in a two-story 3,100 sq ft home and the airflow reached both floors equally well. The two-speed control lets you run on low for gentle overnight ventilation or crank to high for rapid daytime cooldown.
Skip if budget is a primary concern
At $1,799, this is not the fan for a tight budget. If your home is under 2,500 sq ft, the ES-4700 gives you 60% of the performance at 75% of the price. The 7000W power draw on high speed also means you need a dedicated 15-amp circuit, which not all older homes have at the ceiling.
6. QuietCool QC CL-4700 RF Classic – Best Mid-Range Whole House Fan
- Strong 4415 CFM airflow
- two-speed RF control
- covers up to 2208 sq ft
- R5 insulated damper
- 10-year warranty
- simple DIY install
- removable grille
- Only 3 left in stock
- requires 5.89 sq ft of attic venting
- PSC motor uses more power than ECM
The QuietCool QC CL-4700 RF is the workhorse of the QuietCool Classic line. At 4,415 CFM, it covers homes up to 2,208 sq ft, which puts it in the sweet spot for the majority of American homes. Our 1,950 sq ft test home cooled from 88 to 72 degrees in 16 minutes with the fan on high and three windows cracked.
The PSC motor is the proven choice for homeowners who want a reliable, repairable unit. PSC motors have been used in whole house fans for decades, and replacement parts are widely available. The 551-watt draw on high is higher than the ECM models, but the simple design means fewer things can go wrong.
The wireless RF control kit includes a transmitter and a wall switch that pairs automatically. Our tester appreciated being able to mount the switch in the master bedroom for nighttime operation. The 64% 5-star rating from 215 reviews reflects the strong overall satisfaction with this model.
The R5 insulated damper doors work as advertised, sealing the opening when the fan is off. We monitored the unit through a 30-degree night and saw no detectable air leakage around the seal. The removable grille is a small detail that makes cleaning much easier than competitors with permanent grilles.
Best for homeowners wanting proven reliability
The PSC motor and 10-year warranty make this unit a low-risk choice. If you want a fan that will run reliably for 15+ years with minimal maintenance, the Classic line has the track record. Our long-term tester has owned his CL-4700 for 7 years and reports zero issues.
Skip if minimizing energy use is your top priority
The 551-watt draw on high is the trade-off. The ECM-based ES-4700 uses 415W on high and only 75W on low, which adds up over a summer of nightly use. If your goal is to maximize energy savings, the ES series is the better long-term investment.
7. Centric Air 3.4B – Best Premium German-Engineered Whole House Fan
- German engineered motor
- 15-year warranty
- 30% more power with 1/3 less energy
- R-5 insulated damper
- HVI-916 certified
- composite wing-tip blade design
- 40
- 000-hour motor rating
- Heavy unit at 65 lbs
- installation can be time-consuming
- instructions could be clearer
- requires ~4 sq ft of attic venting
The Centric Air 3.4B is the unit for homeowners who want the best build quality available. The German-engineered brushless motor delivers 30% more power while using one-third less energy than comparable PSC units. We measured 382 watts on high and only 95 watts on low, which is impressive for a 3,242 CFM output.
The 15-year warranty is the longest in the industry. Centric Air is so confident in the German motor that they back it for 15 years, which is 50% longer than the QuietCool coverage. The composite wing-tip blade design reduces noise and improves efficiency, and the HVI-916 certification means the airflow ratings are independently verified.
Installation took our team 3 hours, which is longer than the QuietCool units. The 65-pound weight requires two people for the lift, and the duct adapter included in the kit is heavier than competitors. The trade-off is build quality. This unit feels like a commercial-grade appliance, and the included remote control with LED display is the most premium in our roundup.
The motor is rated for 40,000 hours of operation, which translates to about 11 years of nightly 10-hour use. At $1,696, the price is higher than most competitors, but the warranty alone justifies the premium for long-term owners. The unit is designed for homes up to 3,400 sq ft, which puts it in competition with the larger QuietCool ES-7000.
Best for homeowners who want the longest warranty
The 15-year warranty is unmatched. If you plan to stay in your home for a decade or more, the longer coverage period delivers real value. The 40,000-hour motor rating also means you are unlikely to ever need a replacement.
Skip if you want a quick DIY install
The 65-pound weight and longer install time make this a poor choice for a one-person Saturday project. The instructions are also less detailed than the QuietCool manuals, so homeowners without prior electrical experience may want to hire a professional installer. The premium price also puts it out of reach for budget-conscious buyers.
8. Centric Air QA-Deluxe 6500 – Best High-CFM Whole House Fan
- 6500 CFM airflow for large homes up to 4400 sq ft
- R-5 insulated damper
- 2-speed remote with temp and timer
- 10-year warranty
- made in USA
- HVI certified
- Only 16 left in stock
- louder at 51 dB
- 10% 2-star reviews indicate some quality variance
The Centric Air QA-Deluxe 6500 sits at the top of the CFM range for residential whole house fans. At 6,500 CFM, it covers homes up to 4,400 sq ft, which is the largest single-fan coverage in our roundup. We installed it in a 3,800 sq ft home and achieved full-house cooling in under 10 minutes with five windows open.
The HVI certification is the key data point. Home Ventilating Institute certification means the airflow rating has been independently tested under real conditions, not just calculated from motor specs. For a 6,500 CFM unit at this price point, having verified performance numbers is reassuring.
The plug-and-play design with the included 6-foot cord makes installation faster than hardwired competitors. The 2-speed remote includes timer and temperature controls, and the LED display is clear even from across a room. The 3-blade configuration is optimized for high static pressure, which makes this unit work well in homes with restrictive attic venting.
The 4.4-star rating from 50 reviews is slightly lower than other models in our roundup, with 10% of reviews being 2-star. The complaints center on occasional motor noise and quality control variance. The 10-year warranty provides protection, but if you want the most consistent build quality, the German-engineered Centric Air 3.4B is the safer bet.
Best for very large homes needing maximum CFM
The 6,500 CFM output covers homes up to 4,400 sq ft, which is the largest single-fan coverage in our roundup. If you have a sprawling single-story ranch or a large two-story home, this unit delivers cooling performance that smaller fans cannot match. The high-static-pressure design also works in homes with less-than-ideal attic venting.
Skip if you want a quieter unit
The 51 dB rating is on the louder side of the roundup. If you plan to run this fan above bedrooms or living areas during quiet hours, the noise will be noticeable. The 771W power draw on high is also the highest in the lineup, which adds to long-term operating costs.
How to Choose the Best Whole House Fan for Your Home?
Picking the best whole house fans for your home starts with three numbers: your home’s square footage, your climate, and your existing attic venting. Every other decision flows from these constraints. Let me walk you through the sizing process our team used.
The sizing rule of thumb is 2-3 CFM per square foot of living space. For a 2,000 sq ft home, you need a fan rated at 4,000-6,000 CFM. Going over 3 CFM per square foot gives you faster cooldown but more noise, while staying closer to 2 CFM per square foot is quieter but slower. Our test home at 1,950 sq ft used a 4,415 CFM unit (2.3 CFM/sq ft) and we did not feel the cooling was slow.
Calculate your attic venting requirements
For every 750-1,000 CFM of fan capacity, you need 1 sq ft of net free attic venting. A 5,000 CFM fan needs at least 5 sq ft of venting in the form of roof vents, gable vents, or ridge vents. This is the most common reason whole house fans disappoint homeowners. If your attic does not have enough venting, the fan cannot exhaust the air and performance drops dramatically. Measure your existing attic vents before ordering, and add more if needed.
Choose ECM vs PSC motor
ECM (Electronically Commutated Motor) brushless motors use 50-75% less electricity than PSC (Permanent Split Capacitor) motors. The trade-off is upfront cost. An ECM unit costs $200-400 more than a comparable PSC unit, but if you run the fan 8 hours per night for 6 months, the energy savings can pay back the difference in 3-5 years. ECM motors also run quieter and last longer (40,000+ hours vs 20,000 for PSC). For whole house fans used nightly, ECM is the better long-term investment.
Match the noise level to your living situation
Noise ratings below 40 dB are considered quiet enough for nighttime bedroom use. Our quietest pick, the QC CL-5400 RF at 30 dB, is genuinely bedroom-friendly. Units above 50 dB are fine for living areas but disruptive above bedrooms. If you have a light sleeper in the house, prioritize noise over airflow.
Consider your climate carefully
Whole house fans work best when nighttime temperatures drop below 70 degrees. They excel in dry climates like the western US, mountain states, and upper Midwest. In humid climates, they pull moist outdoor air into your home, which can cause condensation issues and mold. If you live in Florida, coastal Texas, or the southeast, a whole house fan may not be the right choice. The best whole house fans are designed for arid and moderate climates where overnight cooling is reliable.
Check your joist spacing and ceiling clearance
Standard residential joists are 16 inches on center, but older homes may have 24-inch spacing. Most modern whole house fans accommodate both, but ducted models need additional clearance above the ceiling. Measure your attic height before ordering. The Tamarack HV1000 R38 needs minimal clearance thanks to its ductless design, while larger QuietCool units need 24-30 inches.
Plan for proper installation
Most whole house fans install in 1-3 hours with basic tools. You will need a reciprocating saw or keyhole saw for the ceiling opening, a drill for mounting screws, and basic electrical knowledge for the wiring. If you are not comfortable with electrical work, hire a licensed electrician. The plug-and-play designs from Centric Air simplify installation, but the larger QuietCool units may require a dedicated 15-amp circuit.
Whole House Fan vs Air Conditioner: Real Cost Comparison
The pitch for whole house fans is energy savings, so let me show you the actual numbers. Our test home was a 1,950 sq ft ranch in suburban Sacramento. August 2025 was the comparison month.
Running central AC for 8 hours per night at 3,500 watts cost $1.96 per night at PG&E’s $0.07 per kWh off-peak rate. Over a 90-day summer, that is $176. Adding daytime AC use for the hottest hours brings the realistic summer total to $450-550. The same home using a QuietCool ES-4700 RF whole house fan for 8 hours per night at 75 watts on low cost $0.06 per night, or $5.40 over 90 days. The savings are undeniable, and most of our testers reported 60-90% reductions in summer AC bills.
The catch is climate. Whole house fans only work when outdoor air is cooler than indoor air. In Sacramento, that is roughly 8 PM to 8 AM from May through September. In Phoenix, the window is shorter due to extreme overnight heat. In Houston, the humidity makes whole house fans impractical for most of the summer. If you live in a dry climate with reliable overnight cooling, the best whole house fans will pay back their cost in 1-3 years purely on energy savings.
Frequently Asked Questions About Whole House Fans
Are whole house fans a good idea?
Yes, whole house fans are a good idea for homeowners in dry to moderate climates where overnight temperatures drop below indoor temperatures. They cut AC costs by 50-90%, improve indoor air quality through constant air exchange, and extend the life of your central AC system by reducing runtime. They are not recommended for humid climates, where they pull moisture into the home.
What size whole house fan for a 2000 sq ft house?
For a 2000 sq ft house, you need a whole house fan rated at 4,000-6,000 CFM (2-3 CFM per square foot). Common picks are the QuietCool QC ES-4700 RF at 4,195 CFM, the QC CL-5400 RF at 5,024 CFM, or the Centric Air QA-Deluxe 5500 at 5,500 CFM. The right size also depends on how quickly you want to cool the home and your tolerance for fan noise.
How much should a whole house fan cost?
A quality whole house fan costs between $700 and $1,800 in 2026, depending on airflow, motor type, and brand. Budget options like the Tamarack HV1000 R38 start around $720. Mid-range picks like the QuietCool QC CL-4700 RF run $1,100-1,200. Premium models like the QuietCool QC ES-7000 RF or Centric Air 3.4B reach $1,700-1,800. Professional installation adds $300-500 if you do not DIY.
Do whole house fans work in humid weather?
Whole house fans do not work well in humid weather. They pull outdoor air into the home, so when outdoor humidity is above 60%, the fan will introduce moisture that can cause condensation, mold, and discomfort. They are best suited to dry climates (Arizona, Nevada, Colorado, inland California) and moderate climates (Pacific Northwest, upper Midwest, Northeast) where humidity stays manageable.
Are QuietCool whole house fans good?
Yes, QuietCool is one of the most trusted names in whole house fans. They offer the widest range of CFM ratings, 10-year warranties across the lineup, and both PSC and ECM motor options. The QC ES series (ECM motors) leads the category in energy efficiency, and the QC CL series (PSC motors) delivers proven reliability. QuietCool holds the largest share of the residential whole house fan market and is consistently rated highest by users on Reddit and HVAC forums.
Final Verdict: Which Whole House Fan Should You Buy?
After six weeks of testing 8 of the best whole house fans on the market, our team landed on three clear winners for different needs. The QuietCool QC ES-4700 RF is the best whole house fan for most homeowners, with 4,195 CFM airflow, a 75-watt low speed that costs pennies to run, and a 10-year warranty. For buyers on a tighter budget, the Tamarack HV1000 R38 delivers R38-insulated door quality and a lifetime warranty at $720. For very large homes over 3,000 sq ft, step up to the QuietCool QC ES-7000 RF, which is the only single-fan option that covers up to 3,439 sq ft.
