Run Attic Fan And Ac At Same 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.

Run attic fan and ac at same time.

It may seem counterproductive to run your fan and your air conditioning at the same time since both use energy to operate. If it s 80 degrees outside that means setting the ac to run at 78 or 75 instead of 70. Both types of attic fans are popular as solar powered equipment. The attic fan consumes much more electricity than any possible saving from reduced air conditioner run time.

The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows. 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. The whole house fan is installed inside the attic between the living space and ceiling. It helps to cool your home temperatures and the attic by approximately 30 degrees.

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. 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. 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.

Since sunlight on the roof is the major source of attic heat attic fans are most useful during daylight hours. Typically people who live in areas that get hot during the day and cooler at night often turn their whole h. 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. If you were to turn on the air conditioner your air conditioner will work very hard because it will work hard trying to.

Essentially you can use your ac unit and your whole house fan together. This can cause problems with your thermostat and overall hvac system. For the ac this means keeping the thermostat closer to the temperature outside. Today ceiling fans are the best selling variety of fan in the united states.

During the summer there is always a benefit to a cooler attic. Increasingly ceiling fans are used not as an alternative to air conditioning but as an accompaniment. One energy concern with whole house fans is heat loss in the winter.
