You know what it looks like, smells like, and sounds like\u2014from the hum of your refrigerator to the &#8220;whooshing&#8221; of water through your dishwasher. One other important piece of equipment that you hear operate is your air conditioner. When strange or unfamiliar sounds come from this important appliance, it\u2019s vital that you not ignore them.<\/p>\n<p>Some odd noises simply mean that you need a small adjustment, while others are indicative of something much more serious. Whatever the unfamiliar noise is, it\u2019s important that you have it addressed quickly and schedule <a href=\"\/service-areas\/nashville-tn\" target=\"_blank\" rel=\"noopener noreferrer\">Nashville, TN AC repair<\/a> with a professional ASAP. Keep reading to learn about the sounds you should never hear coming from your AC system.<!--more--><\/p>\n<h2>Screeching\/Screaming<\/h2>\n<p>Let\u2019s face it, you never want to hear this coming from your cooling system, and if you do, you\u2019ll know something is wrong. Be sure to shut off your AC and call our professionals right away if this occurs. What\u2019s likely happening is that high pressure is rising from a faulty compressor\u2014which is the heart of your air conditioner.<\/p>\n<p>If you ignore this sound, it will result in a domino effect and negatively impact other parts of your system. For example, it could cause a refrigerant leak and render your AC system inoperable.<\/p>\n<h2>Banging<\/h2>\n<p>Sometimes when starting up and shutting down, you may hear a sound that somewhat resembles light banging\u2014but that\u2019s not what we are referring to. We\u2019re talking about a pretty audible banging, that you\u2019ve never heard before.<\/p>\n<p>It can be an indication of any number of problems, such as a loose component or bent fan blade. It may also be due to an obstruction inside or outside the machinery, or something even more serious. Be sure to call us right away!<\/p>\n<h2>Buzzing<\/h2>\n<p>There are a few possible reasons that your cooling system could be making a buzzing noise. Perhaps it\u2019s coming from a blower motor that is wearing out, and therefore needs replacement. It could also mean that you\u2019re dealing with loose wiring that\u2019s not establishing connections.<\/p>\n<h2>Clicking<\/h2>\n<p>Clicking noises are a lot more common than you may realize. Again, this is a noise you could hear during compressor startup and shutdown. But if the clicking persists from the system, then it\u2019s likely a sign you need repairs. The clicking sound could be originating from defective electrical components. For instance, the thermostat might not be connecting properly with the system, but keeps trying to do so.<\/p>\n<h2>Hissing\/Bubbling<\/h2>\n<p>Do you hear a noise that can only be described as hissing, or bubbling? Then it\u2019s likely that you have a refrigerant leak on your hands. A common misunderstanding about this chemical blend of fluids is that it\u2019s <em>supposed <\/em>to leave the system, like gasoline leaves your automobile.<\/p>\n<p>But your cooling system is actually supplied with enough refrigerant upon installation to last its entire lifespan, ideally. Therefore, if you are <em>losing <\/em>refrigerant, then it means you have a leak. This can and will negatively impact the functionality of your air conditioner the longer you neglect it.<\/p>\n<p style=\"text-align: center;\"><strong>Covenant Heating and Cooling is \u201cDedicated to the Promise of Serving You!\u201d <\/strong><a href=\"\/contact\/send-message#breadcrumbs-container\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>Contact us<\/strong><\/a><strong> today for reliable HVAC services. <\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Some odd noises simply mean that you need a small adjustment, while others are indicative of something much more serious. <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[70],"tags":[114,115,92,113],"class_list":["post-438","post","type-post","status-publish","format-standard","hentry","category-air-conditioning-service","tag-ac-repairs","tag-air-conditioning-repairs","tag-nashville","tag-professional-ac-services"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/posts\/438","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/comments?post=438"}],"version-history":[{"count":2,"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/posts\/438\/revisions"}],"predecessor-version":[{"id":441,"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/posts\/438\/revisions\/441"}],"wp:attachment":[{"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/media?parent=438"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/categories?post=438"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.covenantheatingandcooling.com\/blog\/wp-json\/wp\/v2\/tags?post=438"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
