Is it cheaper to use a whole house fan than ac?
A whole house fan is much more cost-effective to run than a traditional A/C system.
While an A/C system runs at 3000 watts or more for smaller homes and much higher for larger homes, a whole house fan runs at under 1000 watts for the largest models and most models at under 500 watts.
This means that a whole house fan costs just pennies in hours, versus an A/C system that runs for dollars an hour.
Think about it like a car. A whole house fan is the green alternative to A/C, just like how an electric car is the green alternative to gas guzzling vehicles.
There are a lot of savings from the initial investment as well. A whole house fan costs between $1500 and $3000 installed, while a new A/C system can cost upwards of $20,000! Combine this with the cost to run, and a whole house fan becomes a no-brainer compared to A/C.
