With the surprising surge in the use of air conditioners to cool the house temperatures, whole house fan installations are bringing a revolution. Substituting the air conditioners in most climates to save more energy and cool more efficiently are why people are preferring to use these more. The combination of whole house fans with the normal ceiling fans and circulating fans create a temperature and moisture balance inside the house that makes the stay indoors comfortable and replenishing even during summers. The benefits of whole-house fans can be felt best when the heat ducts and the cooling systems are modified to suit the temperature. But due to the technology being comparatively new, there had been several questions revolving around it and here we are trying to answer a few.
Do attic fans cool down a house?
The main function of attic fans is to draw the warm air present in the house and throw it outside through the vents on the attic. This is only possible when the windows are open in the house. As the cold air rushes in, the warm air is lifted to the upper area of the house or the attic and the heavy cold air pushes it out. The result is the presence of cold air inside the house that makes the temperature drop and creates a cooling effect throughout. The whole house fans Hawaii work on this principle that looks forward to utilizing natural air and reduce energy consumption.
Is a whole house fan cheaper than AC?
The biggest benefit of whole house fan lies in the fact that they are considerably cheaper and a lot greener than AC. The installation might cost a bit but that is not an incurring cost. And another plus point remains that unlike ACs the whole house fans do not demand to be operational the whole day. Whenever it is turned on, it does not take more than 5 minutes to effectively start cooling the house.
Do whole-house fans work?
Whole house fan installations can be tricky and you must understand the whole usage procedure to make them work correctly. These fans are known to provide their best results when the surroundings and their operational tactics are just proper and perfect. It works best when the surrounding temperature is lower than the temperature inside the house. When the attic vents are opened out, the windows inside the house must be opened too for the cold air to enter the house and push the accumulated warm air out of the attic. Unless the windows and doors are properly opened, this cycle of air replacement is not going to work effectively, resulting in the improper functioning of the whole house fans. The ceiling fans too can be operated at this time for the cold air to spread effectively in and around the house.
How many windows should be open when using a whole house fan?
For the system to work efficiently, the windows, as well as the doors which have an open facing are advised to keep open. The windows must be opened in a fashion that does not counter the air current flow heavily and that will help the entered air to rise proportionately to the attic. However, depending on both the internal and external temperature, the decision of opening the windows must be taken. The more the windows are opened, the faster will be the cooling.
How long does it take a whole house fan to cool a house?
This is an entirely variable concept where the rate of cooling depends on the size of the house, the temperature inside and outside the house, the number of windows opened, and what is the rate of airflow outside. When the whole house fan Hawaii is switched on and simultaneously the windows are pulled open, cold heavy air gushes in and pushes the hot air above to the attic to get instantly vented out of the house. This is a very quick process and does not require more than 5 minutes to start the cooling actions in ideal conditions.
In this way, the mechanism is superbly built for the energy to get saved and the cooling to be efficient.
