Duct, Duct, Duct, Insulate - Insulating Your Ductwork

Have you ever taken a shower and the mirror starts to fog up? For almost all of us, we have experienced this at least one time in our life, probably more often than not. You might open a window, wipe it down with a towel, or think to yourself that you need a better exhaust fan (Air King can help with that!). What a lot of people dont think about is that same steam that is causing your mirror to fog over is also going through your ducting. This presents a prime opportunity for condensation to form within your ducting. Condensation in the ducting forms when the hot steam from the shower passes through the cooler ducting, causing the steam (water vapor) to turn into a liquid form (water). This is especially true in cooler climates of the country. A very simple fix is to use insulated ducting as well as placing insulation around and on top of the actual exhaust fan (Make sure to check the rating of your exhaust fan as to how much insulation can be placed on top of it. Generally fans are rated for at least an R40 factor). By using insulated ducting it does not allow the air flowing through it to cool fast enough to cause condensation.

What is the big deal with condensation? Condensation can be harmful in many ways. Anytime you have sitting water, the potential for mold and bacteria growth exists, so you are working against one of the main reasons you have an exhaust fan in the first place. Another issue is depending on the situation you could cause enough condensation to form that it starts to drip out of your fan and possibly cause damage to the ceiling material around the fan.

Air King, as well as the Home Ventilation Institute and ENERGY STAR® all strongly recommend that insulated ducting be used with all exhaust fans, so take a minute and check to see if your fans ducting is insulated or not. Your fans ducting will thank you!

Clean-Up on aisle 5 – using fans to help dry floors

You just finished washing the floor and the shine of a clean surface is glistening in the sunlight. A job well done. Then you hear it, the kids, the dog, your spouse. With cat like reflexes you protect the area yelling – THE FLOOR IS STILL WET! Then you see your family standing in the middle of the floor as they turn to you and say – what did you say?

Okay maybe it’s not that dramatic in your home, but there is an easy way to help the drying process. Have you ever considered using a pivoting floor fan or utility fan to speed the drying process?  By placing a fan or two around the area, the force of the air rushing across the floor will speed the evaporation process along, drying the floor in a fraction of the time. Now getting them to remove their muddy shoes before coming in the house, unfortunately we can’t help with that. We’re a fan company not miracle workers.

The best fans for the job are ones where you can pivot the head of the fan down towards the floor. This way the airflow is going directly towards the wet floor. Just a note of caution – whenever you are using an electronic devise and water is involved, make sure the power cord and the fan are not sitting in any puddles of water. Also do not have the fan running while you are cleaning the floor to avoid any water splashing up into the motor area. Always check your owners manual for any additional warnings before using your fan.

Having a floor or utility fan in the home can be a great tool. Not only can you use it to help dry the floors, but it can also be used to circulate air throughout the home, help dry a damp basement or garage and many other uses.
