My wife and I both work every day and leave the air conditioner off while we are at work in order to save on our electric bill.
The problem was, when we arrived back home about 5:30 PM, the whole house would be unbearably warm, and it would take our air conditioner on full power until at least 9:00 PM before it would be comfortable downstairs. The upstairs bedrooms would still be too warm at bedtime.
We installed QC-1500 fans in each of our 3 bedrooms upstairs. Now, when we arrive home, the first thing we do is open a couple of windows downstairs and turn on all 3 fans. Within 10 to 15 minutes, the entire downstairs is very cool and comfortable, and at bedtime we close the downstairs windows and open a window in the bedrooms. Immediately the bedrooms cool right down and by midnight we have to them turn off to keep from being too cold.
We now never turn our air conditioner on except weekends when we are home. Even then, the air conditioner is only on from about 2:00 PM until 5:00 PM when we turn it off and start our QC-1500's. We wish to thank QuietCool Mfg. for such an innovative product, and we want them to know that they didn't lie to us about how quiet they are. We sleep in the same room with them on and never even hear them.
