QuietCool Trident Pro 5.5X: Cool the Whole House With Evening Air
In much of Southern California, evenings cool down fast even after hot days. A whole house fan takes advantage of that: open a few windows, turn it on, and it pulls cool outside air through the house while pushing hot air out through the attic. The 5.5X suits the average single-story or two-story home, and California’s Title 24 energy code includes whole house fans as a prescriptive requirement for new homes in several inland climate zones.

How It Saves Money
The fan draws a few hundred watts; a central air conditioner typically draws several thousand. Running the fan on cool evenings lets you skip or shorten AC run time.
Venting Matters
The attic must have enough exhaust vent area (about 6.76 sq ft net free area for this model) or the fan can’t move its rated air. We check and add venting as part of the installation.
