Typically, you might assume that an improperly sealed window or a poorly framed door is the culprit. However, you may need to consider that another potential source of heat loss in your home can be your exhaust fans.<\/p>\n<p>Exhaust fans are a necessary part of your home&rsquo;s ventilation system. They remove unwanted airborne particles and moisture from the room and send them outside into the air. The exhaust duct should only operate as a one-way traffic route for these particles. However, our cold St. Louis winter weather may find itself able to stealthily creep in the wrong way, causing heat loss.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/heat-loss-exhaust-fans-2.jpg\" alt=\"Causes of Heat Loss\" width=\"586\" height=\"274\" class=\"aligncenter size-full wp-image-1076\" srcset=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/heat-loss-exhaust-fans-2.jpg 586w, https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/heat-loss-exhaust-fans-2-300x140.jpg 300w\" sizes=\"auto, (max-width: 586px) 100vw, 586px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Importance_of_Exhaust_Fans\"><\/span>The Importance of Exhaust Fans<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>As mentioned, your home&rsquo;s exhaust fans serve important purposes. In kitchens, they are the mechanism that helps rid the room of smoke, oil, and particularly strong odors. Your kitchen exhaust also has the duty of carrying the steam from your pots of boiling water away, which is vital to protecting the walls and ceiling near your stove from moisture damage. If you are cooking on a gas range, your kitchen exhaust also helps draw away the fumes from lighting the stove. Additionally, a helpful hint for the summer is that your exhaust fan can draw hot air out, letting your air conditioner run with a bit less constraint.<\/p>\n<p>In the bathroom, the exhaust fan serves as a prime function for mold and mildew prevention. Its main job is to remove the warm, moist air from the room after a hot shower or bath, thereby making it harder for mold or mildew to thrive and protecting your walls from moisture damage. It can even allow you to get out of the shower to a clearer mirror, void of an abundance of fog, if the fan is properly sized for the bathroom.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Preventing_Heat_Loss_by_Your_Homes_Exhaust_Fans\"><\/span>Preventing Heat Loss by Your Home&rsquo;s Exhaust Fans<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/heat-loss-exhaust-fans-1.jpg\" alt=\"Heat Loss in Your Home\" width=\"260\" height=\"319\" class=\"alignright size-full wp-image-1077\" srcset=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/heat-loss-exhaust-fans-1.jpg 260w, https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/heat-loss-exhaust-fans-1-245x300.jpg 245w\" sizes=\"auto, (max-width: 260px) 100vw, 260px\" \/><\/p>\n<p>Though more modern exhaust fans are being created with technology that features timers or heaters to limit heat loss, many homes still have regular fans.
