It\u2019s a great choice for homeowners throughout Duluth and the surrounding\ncommunities! It\u2019s actually still the leading heating system found in homes\nthroughout the country, especially in areas like ours that may not have a need\nfor a powerful boiler but still needs effective and efficient heat for our\nchilly winter nights. <\/p>\n\n\n\n<p>They\u2019re cost-effective, and a fantastic choice for many people.\n<em>However, <\/em>when not properly cared for,\nfurnaces can present dangers you might not think about. This is going to be the\ncase for any appliance that utilizes natural gas. They are not dangerous by\nnature, but skipping maintenance or neglecting an aging system can certainly\nlead to problems. One of these problems is a cracked heat exchanger. <\/p>\n\n\n\n<p>Heat exchangers are something you should know about, and\nnever ignore if you suspect you have an issue with one. If this is the case,\nturn off your heater right away and give us a call. <\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\">Wait, What\u2019s a Heat Exchanger?<\/h2>\n\n\n\n<p>This is a great question! This is the component that\nactually provides heat to the air that your furnace\u2019s blower fan sends into the\nventilation system (and then, into your home). It is a clam-shell shaped metal\nchamber, and there is a series of them arranged in rows within your furnace\nsystem. The heat exchangers are where hot combustion gas from the burners\ncollects. <\/p>\n\n\n\n<p>This intense heat from the gas raises the temperature of the\nmetal walls, which makes the outside of the heat exchanger not. This enables\nyour furnace to apply the heat of the combustion gas to the air, but without\nletting those gasses (namely, carbon monoxide, or CO) actually get into contact\nwith your indoor air. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Causes a Heat Exchanger to Crack?<\/h2>\n\n\n\n<p>The heat exchangers in your furnace system go through a lot of stress each winter. Every time they\u2019re heated up, the metal expands. Over time, this constant expansion and contraction weaken the metal, which leads to eventual corrosion. <\/p>\n\n\n\n<p>This is, as you might imagine, a bigger risk in aging furnaces than it is in newer ones. It\u2019s also a bigger risk in furnaces that aren\u2019t vented very well or aren\u2019t properly maintained. What happens is that corrosion weakens the metal even more, and this added strain on the heat exchangers leads to small cracks that can be basically invisible to the average homeowner, but causes major problems for health and safety. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Danger of Cracked Heat Exchangers<\/h2>\n\n\n\n<p>As we mentioned above, the average homeowner won\u2019t actually\nbe able to see cracks on the heat exchanger, but that doesn\u2019t mean they don\u2019t\nexist! In fact, you could probably pour water into a cooled, cracked heat\nexchanger and not even see a drop leak through. <\/p>\n\n\n\n<p>But, what occurs is when the heat exchanger heats up, the\ncracks widen and enables unhealthy gasses (the CO we mentioned above) to leak\ninto your indoor air instead of safely exiting your property through a flue. <\/p>\n\n\n\n<p>If you\u2019re exposed to too much CO, you can experience\nsymptoms like nausea, lightheadedness, dizziness, and more. In very severe\ncases, CO can be fatal. We really cannot overstate how harmful a cracked heat\nexchanger is. <\/p>\n\n\n\n<p style=\"text-align:center\"><strong>For reliable <a rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\" href=\"\/service-areas\/duluth-ga-air-conditioning-heating-plumbing\" target=\"_blank\">furnace repair in Duluth, GA<\/a>, reach out to <a href=\"\/contact\/send-message\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">DC Cheek Heating, Cooling &amp; Plumbing<\/a> today! \u201cFixed, at the Speed of Life.\u201d <\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Heat exchangers are something you should know about, and never ignore if you suspect you have an issue with one.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[76],"tags":[113,99],"class_list":["post-691","post","type-post","status-publish","format-standard","hentry","category-heating-service","tag-duluth","tag-furnace-repair"],"aioseo_notices":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.2 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Why Is a Cracked Heat Exchanger Such a Problem?
