If you are looking for a way to cut down on your air-conditioner use and still keep your house cool, one option is to use a full-house ventilation fan. These fans are generally installed on the top floor of your house and in the ceiling. When you install one of those fans, you will need to make sure that it is wired into your house's electrical systems. Most people prefer to have a switch or knob to turn on the fan. 

How to Wire in a Full-House Ventilation Fan

Working with electricity can be dangerous. If you feel unsure at any point that you can't handle what you are doing, you should immediately hire an electrician to do the job. That way you know the job will be done correctly and safely. You should only try to do this if you have done a lot of DIY projects in the past. 

Turn off the breaker: You don't want power running through the circuit the fan uses while you are working. If you aren't entirely sure what circuit the fan is on, turn off the power to the whole house. Test the circuit before you start anything to make sure that you have turned off the power.

Find the right place for the switch: There are certain things that you are looking for when you decide where to put the switch. One is that it needs to be on the wall near the fan, and the second is that you want to use an existing outlet. If you have an existing outlet, using it will make your job easier. If not, you are going to have to add in more steps. 

Remove the outlet cover: This step actually has several parts. The first one is to remove the cover. The next part is to open up a slot in the back of the outlet box to run a wire to your new switch to. Make sure your new electrical cable is long enough to run from the outlet to the hole for the new switch. In fact, you may want to make sure the cable is longer than you need. You can always cut it down as necessary. 

Connect the appropriate wires: You will want to match up the appropriate wires between the existing outlet and the new cable and then run the cable up through the wall to the hole for the new outlet and into its own wire box. After that, wire up the switch. Then run a cable from the fan itself and down into the switch's wire box and do the same thing. 

Turn the power back on: Once you are sure that everything is connected correctly after you have double-checked your work, it's time to turn the power on and check that it works. 

A whole-house ventilation fan can help you fight the heat and keep your cooling bills down. If you feel like you can handle this electrical-construction project yourself, you can wire things on your own. Otherwise, you should hire an electrician to install and wire your fan .
