Should I install a whole-house fan?
A whole-house fan pulls cool outdoor air through open windows and exhausts hot air through the attic, effectively cooling your home without air conditioning. It works best in climates with cool evenings, like South Jersey. It can reduce AC use significantly and costs about $500 to $1,500 installed. However, it requires adequate attic ventilation and is not effective during hot, humid nights.
Why It Matters
A whole-house fan can dramatically reduce summer cooling costs by letting you run the AC less often. It is a cost-effective alternative or supplement to air conditioning.
