Whole House Fan vs AC: Are fans cheaper to run?
Yes, running a whole house fan is generally less expensive than running an air conditioning system. Whole house fans pull in cool outside air through open windows and exhausts hot indoor air through the attic or roof. They work by creating a draft of air that can cool down your home, especially during the evening, nighttime or early morning when temperatures are cooler.
In contrast, air conditioning systems cool the air by removing heat and moisture from the indoor air. They require electricity to run compressors, fans, and other components, which can result in significantly higher energy bills.
The exact cost savings will depend on various factors such as the size of your home, the efficiency of your cooling system, and local climate conditions. However, in general, whole house fans can save you up to 50-90% on your cooling costs compared to running an air conditioning system.
In summary, if you live in a region with mild to moderate temperatures and humidity, using a whole house fan can be an effective and economical way to cool your home. Not only does it reduce your energy consumption and lower your utility bills, but it also provides a natural and refreshing way to ventilate your indoor spaces. Ultimately, the choice between a whole house fan and air conditioning will depend on your specific needs, preferences, and budget.
