Whole House Fan Review: Energy Savings vs. A/C

A duct-fed Whole House Fan keeps the noise away from the living space (QuietCool System)

My QuietCool Whole House Fan in Action…

Note, this is a personal review. To visit the QuietCool product page on Amazon.com click here.

My family and I live in Southern California and the weather is dry and hot during the day but mostly  cool at night. It is the perfect place for what I consider to be the  most important green upgrade to my home.

A Whole House Fan (WHF). It is an energy-efficient ventilation & cooling system. It can be used instead of Central Air (A/C-System) and, in our case, reduces our monthly electricity bill by 30-60%. I have had my system for over 5 years and for that time, I’m estimating my savings to be $3915.

Whole House Fans are often misunderstood and many homeowners are not even aware that they exist.  But they are so effective in saving energy that as of 2014 the State of California requires them to be installed in all new residential construction (per building code).

So what is a Whole House Fan and how does it work? Please check out my YouTube video, where I demonstrate how a Whole House Fan draws cool outside air into my home, while blowing warmer ambient air into the attic… It creates a fresh breeze and cools the building as a whole (not just the air).

I’m using the Quietcool 1500 Whole House Fan and the Quietcool 2250 Whole House Fan.

To be honest, I didn’t really know what a Whole House Fan was until I first heard about them through my city (during a free green audit). Once I did some more research I quickly became a fan. So, I decided to create this website to help others find valuable information about this technology.

While most websites on this topic are brand specific and try to sell you on their Whole House Fan product, I’m eager to give you independent information on this green technology. I hope to be helpful in getting more people interested in upgrading their homes, saving them money on their monthly energy bill, improve the air they breath and protect the environment overall.

Talking Points I will be addressing on this website include:

Whole House Fan: Top Brand Overview

Here is an overview of the top selling Whole House Fan brands. All systems offer the main benefits of a Whole House Fan system: Energy Savings, Cooling and Clean Air Ventilation. In addition here are the most important pros and cons of the various top brands:

Please note, to see a quick and detailed side-by-side comparison of the various Whole House Fan brands simply click here.

Tamarack HV 1600

Tamarack HV 1600 Whole House Fan

Tamarack TTi-HV1600 HV1600 R-38 Whole House Fan

Pros: 

  • R38 Insulated sealed doors prevent heating to escape into the attic during the winter
  • The fan has 2-Speeds (1,150/1,600 CFM) for more or less ventilation
  • Remote control  so you don’t have to run a new cable in your wall
  • Can be installed horizontally (ceiling) or vertically (wall)
  • The fan creates less of a breeze and more of  a “breath”, which means you don’t have to keep as many windows open.

Cons:

  • Noisy: The fan motor is actually sitting directly in the ceiling and even though it is intentionally a less powerful fan and thus less noisy, you will still hear them more than a QuietCool system. Tamarack has 55db (acceptable) on low and 65db (somewhat annoying) on high. A QuietCool system is 43 db (whisper quiet).
  • The system is underpowered and not as effective in cooling bigger homes

Bottom Line: Instead of trying to create a breeze, Tamarack set out to make an efficient, quiet fan functions at a somewhat slower rate than typical fans. The HV1600 is clearly a good opiton when a homeowner does not want to add attic venting; cannot leave windows wide open at night; is very concerned about fan noise; or lives in an area with cold winters, where there is a large energy penalty from an uninsulated fan.

 QuietCool Whole House Fan “Classic Series”

QuietCool Whole House Fan "Classic" system

QC Manufacturing QuietCool QC 2250 B QuietCool Fan “Classic”


Pros:

  • Whisper quiet (40db): the fan is installed away from the ceiling and hangs in the rafters, a 6 ft. duct leads to the ceiling grid making this the quietest fan on the market
  • Modular design: Various models with single or 2 speed mode allow to design a system that is perfectly sized for your home. (1500-6400 cfm available for 750-4000 square footage of living space per fan)
  • Vertical or horizontal installation for ceiling or walls
  • Easy installation
  • Model that doesn’t require attic space is also available (venting straight through the roof)

Cons:

  • Fans come with built-in damper (R5 insulation) to prevent back flow and heat loss during the winter, but could come with better insulation (winter covers are an optional add on)
  • The higher sized fans (3000 cdm and up) tend to be a bit more noisy than the whisper quiet QC1500 model.

Bottom Line: The base model of the top brand in the market. It is the quietest, most efficient and effective Whole House Fan in the market. The only reason you wouldn’t want to buy this model is because you don’t want to spend upwards of $550 dollars.

QuietCool Whole House Fan “Energy Saver Series”

Quiet Cool Whole House Fan "Energy Saver Series"

QC Manufacturering QC ES-1700 QuietCool Fan Energy Saver

Pros:

  • Rated by the California Energy Commission to be the most energy efficient Whole House Fan available in the market (52 cfm/watt compared to 31 cfm/watt for QietCool “classic series” or 19 cfm for the highest rated efficient competitive product by Systemair/Dayton).
  • Modular design: Various models with single or 2 speed mode allow to design a system that is perfectly sized for your home. (1250-5400 cfm available for 500-3000 square footage of living space per fan)
  • Whisper quiet
  • High Customer Satisfaction

Cons:

  • Fans come with built-in damper (R5 insulation) to prevent back flow and heat loss during the winter, but could come with better insulation (winter covers are an optional add on)

Bottom Line: It has all the benefits of the “classic” QuietCool system and is even more efficient. Priced slightly higher that extra little bit of efficiency may probably be not be worth the investment. But if you are looking for the best of the best, you found it here.

Air Vent Inc. 24″ Whole House Fan

Air Vent Inc. Whole House Fan

Air Vent Inc. 24″ Whole House Fan 54301 Attic & Whole House Fans

Pros:

  • Great price: This WHF is a great choice at a budget as alternative to higher priced brands (50-70% lower price)
  • High customer satisfaction: Those who purchased this model are overall very happy with the benefits of this model
  • Strong belt-driven motor (4500CFM)  creates strong draft lowering the chill factor even further
  • Amazon Customer Rating: 4.5 out of 5 stars (90 Reviewers)

Cons:

  • Fairly noisy as the motor sits right at ceiling level
  • Shutters are a bit flimsy and rattle
  • Shutters are not tight (heat loss during winter as warm air escapes into the attic)
  • Belt/chain-driven motor requires occasional maintenance

Bottom Line: A very inexpensive system that is powerful and has plenty of happy customers. Noise levels are a bit of a concern (as with most WHF that have the motor attached straight to the ceiling), so if it is anywhere close to where you are going to be for most of your day, you might want to consider a QuientCool system.

  • Amazon Customer Rating: 4 out of 5 stars (44 Reviewers)

Cons:

*Motor: Generally a duct-fed Whole House Fan is the quietest as the actual motor/fan blades sit in the rafters of the attic up to 6 feet away from the ceiling grid. A belt driven motor tends to be less quiet than a direct driven motor but generally requires more energy use and has some wear.
