How well does a whole house fan work in Arizona?

A whole house fan is used to push hot air out of a home and bring in crisp brand new air from outside in order to cool the home for the remaining hot portion of the day. These machines are great for most climates, however, they may not be best for all climates.

On days that have extreme humidity, for example, it may not be best to use a whole house fan. This is because you would likely bring in too much water vapor and cause your home to feel extremely humid albeit cool. This is why specific states can be perfect for a whole house fan and others may not be as beneficiary.

One state that is frequently inquired about is Arizona. This state is the one that there are the most questions about simply because it is one of the hottest states in America. Temperatures there can reach up to 110 degrees Fahrenheit so a whole house fan could be extremely beneficial for a home in a place that gets such extreme heat.

The downside may be that the temperature never really cools down or the humidity may be too high to use a cooling system like this in a home. However, according to Current Results, Arizona is the least humid state in the country, especially in Tuscon.

Arizona also tends to cool off in the Summer despite their extreme heat. Also per Current Results, Arizona can reach highs up to 95-106 degrees Fahrenheit in the Summer but still usually dips back down to 79-83 degrees at night. This is ideal for a whole house fan that relies on cool night in order to bring in colder air to cool the home.

So, the general answer for this question would be simple. A whole house fan works extremely well in Arizona and it may just be the perfect place to own this type of machine.
