You expect to hear several sounds as your home\u2019s AC runs: the fans, the motor powering the compressor, the drip of water from the condensate pan, and the movement of air through the ductwork. It\u2019s an easy set of sounds to become accustomed to until it turns into part of the soundtrack of summer\u2014a soothing white noise for hot days.<\/p>\n\n\n\n<p>Then \u2026 something strange interrupts the AC soundscape. Something odd, or loud, or unexpected. Could it be a malfunction in the AC? <\/p>\n\n\n\n<p>It might, and we\u2019re going to look over a few of the more\ncommon cautionary sounds you might hear from your air conditioning system. When\nin doubt, you\u2019ll want to have trained HVAC technicians on the job to see what\u2019s\nwrong, and what needs to be fixed.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\">A Guide to the Common AC Warning Sounds<\/h2>\n\n\n\n<p>Here are the most common kinds of noises you\u2019ll hear from an\nAC that indicate something may be wrong.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Rattling: <\/strong>Although this is an alarming\nsound, it may be something simple. Check to see if the door of the AC cabinet\nis latched. If this isn\u2019t the problem, you may have a loose part inside the air\nhandler, or the cabinet is loose on its foundation. Have a technician find the source\nof whatever is loose.<\/li><li><strong>Clanging:<\/strong> This sharp metal clanging noise\nfrom either the indoor or the outdoor cabinet often means a bent fan blade that\u2019s\nstriking the outer casing. Turn the air conditioner off immediately to avoid\nfurther damage and then call for repairs.<\/li><li><strong>Shrieking:<\/strong> A high-pitched metallic\nshrieking is a warning that the bearings in the motors are wearing down. If the\nbearings wear out completely, the motor will fail. If you have a technician\nreplace the bearings in time, you\u2019ll prevent further damage to the motor\u2014so make\nsure you act right away.<\/li><li><strong>Grinding:<\/strong> This is another motor warning sound,\nbut it often indicates the motor is on the verge of burning out because of\nmechanical stress. Technicians may be able to rescue it, but you\u2019ll likely need\nto have a new motor put in.<\/li><li><strong>Clicking:<\/strong> Clicking sounds are often due\nto failing capacitors, the electrical components that send voltage to the\nmotors to start them and keep them running. Capacitors will usually fail before\nthe AC system does, so you can expect to need to have them replaced at some\npoint in the unit\u2019s life.<\/li><li><strong>Hissing:<\/strong> This probably leaking\nrefrigerant. You\u2019re heating the high-pressure refrigerant gas escaping from the\nlines. Loss of refrigerant can put the entire system in danger if it isn\u2019t\ncorrected. Call technicians to find the leaks, seal them, and then restore the\nproper amount of lost refrigerant. <\/li><\/ul>\n\n\n\n<p>When you need <a href=\"\/service-areas\/west-chester-pa\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">air conditioning repair in West Chester, PA<\/a>, call on our experienced team.
