On top of that, it doesn&rsquo;t typically have a telltale smell and unless leak detection dye is mixed with the refrigerant (some cars come with this), you won&rsquo;t see anything except the greasy residue where the refrigerant oil has leaked out along with the refrigerant. The oil travels in the gaseous refrigerant to lubricate the compressor.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/blog\/wordpress_assets\/CP_LOGO_COLOUR_RGB_Blue\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n\n<h2 class=\"wp-block-heading\">Other Signs of a Refrigerant Leak<\/h2>\n\n\n\n<p>Not all of the problems caused by a freon leak can be identified visually. It&rsquo;s important to watch out for the following signs if you&rsquo;re worried about a refrigerant leak in your vehicle.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A\/C Blows Warm Air<\/h3>\n\n\n\n<p>One of the biggest indicators that there&rsquo;s a refrigerant leak in your vehicle is if the air conditioner doesn&rsquo;t cool the cabin.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Hissing Sounds<\/h3>\n\n\n\n<p>Another sign of a refrigerant leak is if you hear a hissing sound. Note that you will only hear this if there is a very large leak, and you&rsquo;re standing near the system when it&rsquo;s punctured.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Increased Humidity<\/h3>\n\n\n\n<p>Air conditioners do more than release cool air into the cabin. They&rsquo;re also responsible for circulating air, removing the hot and dense air inside the vehicle, and converting it into colder and more breathable air.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is It Safe to Drive With a Refrigerant Leak?<\/h2>\n\n\n\n<p>Yes, it&rsquo;s possible to drive with a refrigerant leak, and there are a lot of people who will because they can&rsquo;t afford to have the leak repaired. It won&rsquo;t hurt the system unless you&rsquo;re having it evacuated and recharged so often that the oil is lost and the compressor is destroyed from lack of lubrication.<\/p>\n\n\n\n<p><\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> 3<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>What Does a Freon Leak Look Like?
