When you’re looking for real estate in Smyrna, assessing the HVAC system is always a significant part of assessing the property on the whole. In recent years, you might have heard the term “whole-house fan” come up more often. Whole-house fans are growing in popularity throughout the nation, as they can significantly reduce the cost of cooling a home. While the principles of operation for these fans are no different than they are for any other fan, the way they’re employed is clever and quite effective.
Whole-house fans are mounted in the attic space of a house. These are large units; large enough to get air flow going through the entire home. The airflow they create is the key to how they cool the home.
If you’ve ever spent a hot Georgia day sitting in front of a box fan, you know that there’s only so much the fan can do. It can create a wind-chill effect, cooling you off a bit, but if it’s just blowing hot air around the room, the effectiveness is pretty limited. Hence, most residents in Smyrna use AC during the hottest part of the summer.
Whole-house fans won’t necessarily replace AC, though they might do the trick in some properties, but they can make things easier for your AC system.
When you fire up the whole-house fan, it starts pulling air into the house through your windows. At the same time, that airflow starts forcing hot air out of the house through the attic and roof vents. Think about how, even late at night, an overheated house will have spots, usually near the ceilings and on the upper floors, that are superheated, even after the rest of the house has cooled off. Whole-house fans create an air current that pushes that superheated air out, pulls cooler air in, and that reduces the load on your AC.
Advantages and Disadvantages
For a whole-house fan to work most efficiently and effectively, it generally has to be around ten degrees cooler outside than it is inside. This is why they usually cannot entirely replace an AC unit. If it’s 80 degrees outside and 85 degrees inside, you’re not going to get much relief by pulling that hot outside air in. However, combined with good cooling, whole-house fans really can make a difference, both in terms of how fast your house cools and how much your AC has to work to finish the job.
