An AC unit is an efficient way to cool a home, but even a properly sized AC unit can struggle to cool a home down after a long day of combatting heat gain. On the other hand, a whole house fan can cool a home in a matter of minutes. While it would not be wise to replace your AC unit with a house fan, you can save money on operating costs if you add a house fan to an already existing AC unit.
The Strengths and Weaknesses of an AC Unit
An AC unit cools air by using a fan to push the hot air inside your home over evaporator coils. The refrigerant vaporizing inside the coils will absorb heat from the air, and the air thus cooled will then cool your home. This means that no matter how hot it gets outside, your AC unit will be able to provide at least some cooling to your home. On the other hand, an AC unit is one of the most expensive home appliances to operate. Furthermore, an AC unit can only process so much air at a time, so it can take your AC quite a while to catch up when the temperature inside your home climbs.
How a House Fan Can Help
It is important to note that a whole house fan is not the same thing as a ceiling fan. While a ceiling fan is designed to move air around one room, a house fan is designed to cool your whole house. It accomplishes this by venting hot air out of your home through the attic. For the best cooling, you should wait until the outside temperature falls below the temperature inside your home. You can then open your windows, turn off your AC unit, and use your house fan to pump cool air into your home as it pumps hot air out. In this way, a house fan can cool your home in a matter of minutes. Furthermore, because a house fan uses 10% of the electricity that an AC unit requires, you can save money by using your house fan whenever possible.
During the hottest times of the day, an AC unit is exactly what you need to fight off the heat. On the other hand, once the outside temperature starts to fall, your AC unit can labor for several minutes or hours to cool your house down. By way of contrast, a house fan can cool your home in a matter of minutes. Thus, combining an AC unit with a house fan will improve your ability to keep your home cool and save you money in the process.
