The acronym HVAC is often used to refer to heating, ventilation, and air conditioning systems. Because heating and cooling your home are too of the largest bills that you have to contend with, it makes sense to do whatever you can afford to improve the efficiency of your HVAC system. Installing a house fan is a good way to help provide some cooling relief and save money at least during the summer months:
What Is a House Fan?
The term house fan does not simply describe a fan that is designed for use inside a home. Instead, a house fan is one that is designed to cool your entire home. That's right, one fan to cool your entire house. To accomplish this feat, workers cut a hole into the attic of your home. They then place the house fan in the hole thus created so that the house fan can vent heat out of your home through the attic. In order to not overheat your attic, you may need to install more vents or even an attic fan to evacuate the heat from your attic.
How Does a House Fan Work?
A house fan works best when it can replace the air in your home with air from outside. Using a house fan during the hottest hours of the day is not advisable, as you will simply be pulling heat into your home as you run your house fan. On the other hand, once the outside temperature starts to fall, you can open your windows and use your house fan to pump all of the hot air in your home out in a matter of minutes and replace it with cool outside air.
Thus, instead of making your AC system chug along for hours trying to cool your home, you can cool your home in a matter of minutes. Furthermore, if you run the house fan through the night, you save money because a house fan uses 90% less electricity than an AC system. Finally, a house fan can help to cool the structure of your building, and the colder this structure is in the morning, the longer it takes for your home to heat up during the day.
By using a house fan to relieve your AC system from the evening through the early morning hours, you can put a big dent in your cooling costs. While a house fan might not be right for everyone, if one is a good fit for your home, it is definitely worth looking into buying one. Talk to an HVAC contractor to see if a house fan could work in your home.
