Important to size the fan for the SF of your living space. Also need to make sure whatever attic space the fan is located in has adequate venting.

He basically said that the swamp cooler could be used as a whole house fan when it's on vent (no cooling) mode, but it had the option to cool if you wanted to use it in the daytime. He also said that the swamp cooler was on the roof and he could barely hear it during the night (Breezeair is very quiet, evidently).
We have a swamp cooler and two whole house fans (we're in a one story ranch). Right now the fans are on and sucking in nice cool air. We'll shut them off when it's bedtime or else we'll freeze

The fans are a bit noisy (installed in '96, so a bit old now), but work great if the air cools down at night. We don't have a lot of muggy nights, so it's usually pretty good. They pull air into the attic, so there are extra vents on the roof to help exhaust the air.

The swamp cooler works so well it's scary. I really don't know why these things aren't used more in newer developments in Colorado. A/Cs are expensive to install and run, swamp coolers are not. We can easily get the inside temperature down in the 60F no problem when it's in the 90s outside in the day. However, if it's hot and humid, we are SOL. The swamp cooler does push air down a single vent and rooms not immediately around that don't get the full benefit. And during the day we have to crack windows to allow the swamp cooler air to circulate around the house, but our pack of rabid, gun-toting ninja wolves keep us safe.

The swamp cooler maintenance is pretty easy, drain all the water and blow out the line before the first hard freeze in the fall. Hook up the water line in the spring. Every few years get new pads or clean them (I put in synthetic pads last year, we'll see how they hold up).

We don't really run the swamp cooler to pull in cold air, probably because we have the two fans that can move *a lot* of air.

Well, the house fan installer came by today to have a look. It turns out, the attic space on either side of our finished attic bedrooms aren't big enough to install the fan we wanted. Not even a 24 inch fan could be properly installed.

The installer offered a pretty cool, but much more expensive solution - the QC1500 from Quiet Cool Whole House Fans - Installs in your attic. Very interesting - it has a smaller grille attached to a soundproof/vibrationproof duct that connects it to a 1500 CFM fan that is suspended from the roof. This makes the fans very quiet, much quieter than a traditional fan.

The problem is that they only move 1500 CFM so you need multiple units and that gets expensive (i.e. 500 + installation for each). Lot's of money, but with 4 of them I'd have 6000 CFM and one very amazing feature. We could install one to each of our 3 bedrooms and one to the hallway. Each would have their own switch and could be run independently, or they could all work together to vent the house. Our attics (kneewall type) is just right - we could get a vent into each bedroom no problem.

I am considering getting 3 of these and maybe even 4. Anyone seen or heard about these units? They are fairly new but what little review/feedback I can find on the Internet is very good.

We have a Quiet Cool Quiet Giant 4500, which is the largest version of the fan you are considering. It has two speeds and works beautifully. Installation of our unit was very quick (the crew was done before lunch) and mess-free. We also had additional roof vents cut into the eaves at the same time.

That is good to hear. I am hoping that 3 separate units - one intake in a 2nd floor hallway, one on a 2nd floor bedroom, and one in the small finished attic (hottest place in the house). We will add 6 new vents. The house is 2000 sq ft. How large is your house?

Never had the chance to test the one out in the home we were under contract with, but our realtor swore by his as a great alternative to running the A/C all night, enough so that we added it to the list of desires in our housing search

We have just under 1800 sq. ft. in an open two-story. The fan is installed in the attic space at the top of our stairs. The grill is probably 18"x24" and to winterize the system, we just unscrew it, place a piece of solid insulation in the open space, and replace the grill.

Based on your experience, do you see any reason that 3 1500 CFM units shouldn't work in the same way as one 4500 CFM unit? I am really liking this whole approach and it's very economical.

I really don't have any idea. I would have to defer to your installer's expertise in the matter. Perhaps you could find another ventilation specialist to give you a second opinion?

We are very happy with our whole house fan, and we wish we had done it sooner. It does a fantastic job of cooling our house in the evening and keeps our energy bills manageable. Bonus: when somebody goes a little crazy in the kitchen and burns something, it quickly disperses the smoke. (Yes, that happens frequently, as my oldest is learning how to cook.)

These quiet ones must be a big improvement over the older models. We call ours "the train". We've been in our house 21 years, and the fan was here when we bought it, so it's at least that old. You have to turn up the TV when it's on. Even a few years ago, DH inquired about the noise levels of the new ones at Home Depot, and was told, yes, they're noisy.

Anyway, we're looking at a swamp cooler now. Our house does get hot during the day, especially if we're home and coming/going a lot. The second story bedrooms don't always cool off well, even with "the train", ceiling fans, etc.
