But what happens when your AC suddenly stops cooling? At Residential Heating and Air Conditioning, we understand how frustrating this can be, and we&#8217;re here to help with <a href=\"\/air-conditioning\/ac-repair\" target=\"_blank\" rel=\"noopener\" title=\"ac repair in Minneapolis\">AC repair in Minneapolis<\/a>. Here&#8217;s a look at why these breakdowns occur and how we tackle them.<\/p>\n\n\n\n<h2>When does it make sense to call a professional if your AC suddenly stops cooling?<\/h2>\n\n\n\n<p>Call a professional HVAC technician if your air conditioner suddenly stops cooling and you notice any of the following:<\/p>\n\n\n\n<ul><li>The thermostat settings are correct but the unit still won\u2019t cool (possible thermostat malfunction).<\/li><li>The unit has a refrigerant leak or low refrigerant level (system can\u2019t cool effectively).<\/li><li>Evaporator coils are frozen (often due to poor airflow), blocking cooling.<\/li><li>Electrical failures \u2014 for example a tripped breaker or faulty wiring causing the unit to shut off.<\/li><\/ul>\n\n\n\n<!--more-->\n\n\n\n<h2><strong>Common Causes of Sudden AC Failures<\/strong><\/h2>\n\n\n\n<p>Several issues could cause your air conditioner to stop working unexpectedly:<\/p>\n\n\n\n<ul><li><strong>Thermostat Issues:<\/strong> Sometimes, the problem is as simple as incorrect thermostat settings or dead batteries. Other times, the sensor might malfunction, telling your AC to shut off prematurely.<\/li><li><strong>Refrigerant Leaks:<\/strong> Your AC needs refrigerant to cool the air. If there&#8217;s a leak, your system won&#8217;t cool effectively. In many cases, refrigerant problems are linked to larger performance issues like<a href=\"https:\/\/www.resheatandair.com\/blog\/air-conditioning-service\/what-is-short-cycling-and-why-is-it-bad-news\/\"> what short cycling means for ACs<\/a>, which can strain your system and lead to further damage.<\/li><li><strong>Frozen Evaporator Coils:<\/strong> If your AC doesn&#8217;t get enough air, the coils can freeze. When this happens, the ice blocks the air, and your unit stops cooling.<\/li><li><strong>Electrical Failures:<\/strong> Electrical issues such as tripped breakers or faulty wiring can also cause your AC to shut down suddenly.<\/li><\/ul>\n\n\n\n<h2><strong>Importance of Professional Diagnosis<\/strong><\/h2>\n\n\n\n<p>AC systems are complex.
