As leaders in the HVAC industry, we have been serving home and business owners since 1950, and can help you with all of your furnace questions, from &ldquo;Why does my heater smell bad?&rdquo; to more.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Types_of_Smells_Does_Your_Heater_Produce_and_Why\"><\/span>What Types of Smells Does Your Heater Produce and Why?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are many different smells that can come from your furnace, and they all have different meanings and causes. So if you find yourself asking &ldquo;Why does my heater smell bad?&rdquo;, it is important to look at the particular type of smell. Some common problems include:<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Musty_Smell\"><\/span>Musty Smell<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This type of musty smell occurs due to high humidity in the air acting upon the heater, or water retention inside the heater. It can smell very stale and when the heater works, the musty smell may spread around the house. Mildew growth in the ductwork is another reason for musty smells from your heater.<\/p>\n<p><strong>What to do about it?<\/strong> \u2013 If you notice a musty smell from your heater, you will need to get your ducts, vents, and filters cleaned completely. Ensure that any mildew is removed and make sure the heater is completely dry on the inside.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Burning_RubberPlastic_Smell\"><\/span>Burning Rubber\/Plastic Smell<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\/why-does-my-heater-smell-bad-2-300x201.jpg\" alt=\"Reasons for Bed Heater Smells\" width=\"300\" height=\"201\" class=\"alignright size-medium wp-image-11817\" srcset=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/why-does-my-heater-smell-bad-2-300x201.jpg 300w, https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/why-does-my-heater-smell-bad-2.jpg 600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>If you get the smell of burning plastic or rubber from the heater, it is probably because something is burning inside the machine. Usually, when you overwork your heater, the internal components start to overheat. Although these components are heat-resistant for the most part, they can still start to singe, causing the burning smell. Additionally, the burning smell might be emanating if there is some flammable debris inside the heater and it is getting singed.<\/p>\n<p><strong>What to do about it?<\/strong> &#8211; A burning smell can be an indicator of a safety hazard. Switch off the heater for a little while and let the machine cool down. If it is a gas heater, turn off the gas supply to the heater\/furnace to avoid any safety issues. Get your heater serviced by an expert technician and also get any damaged parts replaced.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Rotten_Eggs_Smell\"><\/span>Rotten Eggs Smell<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If you notice a sulfur or rotten egg smell coming from your furnace, then the answer to &ldquo;Why does my heater smell bad?&rdquo; may be an indication of natural gas leak. This can be dangerous if you do not take immediate action. Other reasons for such a rotten smell could be dead animals, rodents, or insects lodged inside your heater.<\/p>\n<p><strong>What to do about it?<\/strong> &#8211; Sometimes, especially during winter, rodents, insects, birds and other small animals try to find warm and cozy places inside your walls, to keep themselves cozy. If they wind up in your HVAC ductwork, it can affect your heater. If the rotten smell is a result of animal remains in the heater, then it is important to get a technician over to get rid of the dead animal remains. However, if the rotten eggs smell is due to a natural gas leakage, you need to contact your gas company as well as HVAC experts immediately.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Contact_Us_to_Learn_Why_Your_Heater_Smells_Bad\"><\/span>Contact Us to Learn Why Your Heater Smells Bad<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>At Galmiche &amp; Sons, we have immense experience in identifying and repairing issues that result in smelly heaters.
