That s why the energy required to run an attic fan is wasted.
Run attic fan and ac at same time.
Essentially you can use your ac unit and your whole house fan together.
This means running the whole house fan will cost approximately 90 percent less than running a central air conditioning unit for the same amount of time.
It is important to remember that you should never use the fan mode for a central air conditioning unit the same way you use a regular room fan.
During the summer there is always a benefit to a cooler attic.
It may seem counterproductive to run your fan and your air conditioning at the same time since both use energy to operate.
The attic fan consumes much more electricity than any possible saving from reduced air conditioner run time.
Today ceiling fans are the best selling variety of fan in the united states.
It helps to cool your home temperatures and the attic by approximately 30 degrees.
The trick is to use them wisely and on lower settings.
The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows.
This can cause problems with your thermostat and overall hvac system.
Running the fan for a long period of time with any system central air or window box will also increase the humidity in the room.
One energy concern with whole house fans is heat loss in the winter.
To maintain energy efficiency when it is not in use the outlet for the whole house fan should be sealed to prevent heat from escaping into the attic.
Both types of attic fans are popular as solar powered equipment.
Whole house fans work on the principle of removing the hot and humid air out of the house.
For the ac this means keeping the thermostat closer to the temperature outside.
If you were to turn on the air conditioner your air conditioner will work very hard because it will work hard trying to.
When your fans are powered by the sun and set to start automatically they ll run exactly when you need them without you having to flip a single switch.
However if the air outdoors is cooler than the air indoors it doesn t make a whole lot of sense to turn your air conditioning system on.
The drawback is that you will also draw in the humidity of the outside air.
Since sunlight on the roof is the major source of attic heat attic fans are most useful during daylight hours.
Increasingly ceiling fans are used not as an alternative to air conditioning but as an accompaniment.
