Run Attic Fan And Ac At Same Time

That s why the energy required to run an attic fan is wasted.

Run attic fan and ac at same time.

The attic fan consumes much more electricity than any possible saving from reduced air conditioner run time. This can cause problems with your thermostat and overall hvac system. It helps to cool your home temperatures and the attic by approximately 30 degrees. If it s 80 degrees outside that means setting the ac to run at 78 or 75 instead of 70.

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. One energy concern with whole house fans is heat loss in the winter. 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. Increasingly ceiling fans are used not as an alternative to air conditioning but as an accompaniment.

The trick is to use them wisely and on lower settings. Today ceiling fans are the best selling variety of fan in the united states. The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows. Both types of attic fans are popular as solar powered equipment.

The drawback is that you will also draw in the humidity of the outside air. 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. Essentially you can use your ac unit and your whole house fan together.

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. 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. If you were to turn on the air conditioner your air conditioner will work very hard because it will work hard trying to. Typically people who live in areas that get hot during the day and cooler at night often turn their whole h.

Since sunlight on the roof is the major source of attic heat attic fans are most useful during daylight hours. It may seem counterproductive to run your fan and your air conditioning at the same time since both use energy to operate. 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.
