A whole house fan is an energy-efficient ventilation system that cools your home by pulling in fresh outdoor air and exhausting hot, stale air through the attic. It works by creating a negative pressure system, producing a breeze that flows through open windows, instantly making the space feel 5-10 degrees cooler. 

The long answer is that a whole house fan will save you money! On average users save 50-90% directly on AC related costs plus extend the life of their HVAC unit and roof, both of which are very costly to repair or upgrade. 

The upfront cost to install a whole house fan in the greater Los Angeles area depends on a few factors such as the size  of your home and consequently the size fan required. The total cost may range from $2600 to $6000. 

In addition to cold hard cash saved, a whole house fan provides numerous functional and health benefits to your home. By completing 15-22 full air exchanges per hour, the whole house fan improves indoor air quality, reduces indoor allergens and minimizes the spread of viruses or bacteria. The active breeze provides instant comfort and can help to quickly clear odors or remove excess moisture.
