What is a Whole House Fan? 

A Whole House Fan is a fan that is mounted above your ceiling. The fan is typically mounted up in the attic on the  joists. The ceiling on the upper Floor of the house is used.  For example if it’s a two-story house the second floor ceiling would be where the fan is mounted.  A cut out In the ceiling drywall is required. 

Why would you install a Quietcool whole house fan?

Installing a Whole House Fan is a efficient way of lowering electricity bills during months when the outside temperature is perfectly acceptable. running a fan uses much less electricity than your HVAC air conditioning unit. The fan can be used along with radiant barriers to minimize heat buildup. 

Where would you position the Quietcool Whole House Fan?

It’s a good idea to place the Quietcool fan in a location that is centralized. although it would be a good idea to place the fan further away from where the noise may be an issue for some people.  For example, close to a TV room as it may be harder to listen to the TV due to the humming sound from the fan.  It would also be a good idea to place the fan further away from the colder side of the house.  This way the windows can be open on the colder side, or cooler side of the house, that is not being cooked by the Sun.  That cool air can travel a much further distance before it’s exhausted out the fan.  This will cool off the rooms along the way as the air travels.  The hot sides of the house would have the windows and curtains closed to keep heat out.

The three biggest issues that would hold some back from installation would be:

  1. Weight of the fan.  Carrying it up the ladder and screwing it to a rafter.  This would be alot easier with 2 people.
  2. Drywall – Cutting the wall or ceiling.
  3. Electrical – If hard wiring it for the multispeed switch which costs extra.  A electrical outlet is required for the plug.  Hiring a Electrical contractor or electrician for the hard wiring or outlet installation is a good idea.  Working with electricity is dangerous.  This would have the electrical portion installed up to code as well.

QuietCool ES-2250 Fan Speeds and Wattage:

CFM= Cubic feet per minute of airflow.  A general rule of thumb is to double the square footage of your house and that is the best choice for CFM.  Example a 2000 square foot house would need a 4000 CFM Fan or more for the best airflow in the highest of outside temperatures.

Whole House Fan Installation steps

  1. First decide where the fan will be located.
  2. Next gather all your equipment. Be sure to use the proper dust mask P100 filters are a goo choice.  Safety glasses are essential as well. Have good shoes with string grips and a long sleeve shirt  Gloves with rubber palms are helpful to grab things, like rafter and metal fan parts, and protect hands.
  3. Some tools that are required would be a small drill with screw bits, a drywall saw, caulk, a awl or hole punch, screwdrivers.  See the whole house fan installation video.
  4. Find the location in the Attic and Trace the template cutout area. Use a awl, or small drill bit to make a small hole at one corner .  Now look at it from the living area.  Do that again for another corner of the template area.  Remember the damper box must be mounted and screwed into at least one joist.
  5.  After the cutout in the drywall, (sheetrock, gypsum board) is made then it’s time to put the damper box in the cutout to see if it fits.  If Damper box fits properly then caulk the area and put the damper on top of the caulk.
  6. Next screw the damper box into the floor joist or ceiling joist depending how you look at it.
  7.  Now it’s time to put two screws into the attics rafter(do not screw in fully) or whatever piece of wood you are mounting it to.  When putting the screw into the rafter be sure not to screw it in all the way and leave space to hook on the metal strap that will hold the fan.  After hooking the fan strap and its angled how you want then tighten screw fully.
  8. Now it’s time to connect the duct between the fan and damper box.
  9. The final step in the Attic will be to attach the support strap to the whole house fans flexible duct. you can use the screws or a staple gun with the proper staples.
  10. The last step is to install the vent grill by using a few screws to screw the grill into the damper box.
  11. The unit at this point was either hard wired or needs to be plugged in.
  12. To add to simplicity and convince. I used a Amazon smart plug that is plugged into a surge strip.   The amazon smart plug works with Alexa to turn the fan on and off.

QuietCool Whole House Fan ES-2250 Review

A whole house fan is something I should of purchased many years ago.  It has saved alot of money by cutting my electric bill by as much as half or more depending on the time of year.  There are many months in Florida (at least 8).  During these months the fan can be used all day, or in early morning or at night when the sun goes goes down.

The Quietcool fan when installed with the CFM matching the square footage of the house (1 to 1 ratio) provides good airflow on lower temperature days such as 84 degrees and less.  This would be with moderate humidity.  If cooling and a breeze is required on hotter days such as 87+ degrees then 2 of these Quietcool Fans installed would be ideal.  Keep in mind that a single fan with double CFM could work as well but provide less flexibility with strategic fan locations.  Such as one over a Master bedroom and one in a Hallway.
