Honeywell HW-628 Twin Window Fan

I bought three for our un-airconditioned house. We've only owned them a month or two, but they've been working beautifully so far. They're relatively quiet and move the air through the house well. I thought the thermostats were going to be superfluous. But I really like the convenience of them turning themselves on and off.

Great airflow, good size. fits in the window nicely (horizontal or vertical). I guess I was expecting a little more quiet operations. It is not bad (I sleep with the fan on) but louder than I expected.

I had this unit for about a month now and it has been it has been a workhorse in keeping me cool this summer. It has a slight audible whine and increases somewhat at higher speeds but not enough to disturb me (I had been using a 20 inch box fan that moves about the same amount of air for a penalty of 3 times the noise and didn't even fit in my window). I appreciate the temperature control which stops the rotation of the propellers when it reaches your adjusted setting then restarts them when the air goes above your comfort level. I highly recommend this unit as an alternative to running a power guzzling air conditioner.

The unit is well described by prior reviews and is good. My only comment is that it is not well designed to fit sidewas sliding windows leaving gaps at the edges, i.e. top and bottom of the unit when in place.

Even our cats like the Honeywell. Nice cooling breeze when the house heats up. We are at 8000 feet elevation in the Rockies and it is perfect for our climate to cool things down when the late afternoon heat builds up.
It's a little noisy, but it moves a lot of air and fits very well in the casement windows.
