Some of the common causes of an AC unit freezing are:<\/p>\n<ul>\n<li><strong>Insufficient Air Flow<\/strong> \u2013 Insufficient air flow across the air conditioner&rsquo;s evaporator coil can cause an HVAC unit to freeze over due to a failure of heat exchange.\u00a0 In other words, if the air conditioner is not passing the indoor air over the evaporator coil, before blowing it back into the house, the heat is not being removed from your home and the Freon will instead cause the HVAC unit to freeze.<\/li>\n<li><strong>Low Refrigerant<\/strong> \u2013 If your air conditioner&rsquo;s refrigerant is low, it can lead to a frozen HVAC unit as well. The cause is due to the Freon in the system over expanding since there is less of it to properly cover the system.<\/li>\n<li><strong>Low Outdoor Temperatures<\/strong> \u2013 Air conditioners are meant to function in a set temperature range. If the outdoor temperature is lower than 62 degrees, and you are running the air conditioner, your HVAC unit may freeze because of a drop in pressure in the system.<\/li>\n<li><strong>Mechanical Failures<\/strong> \u2013 A mechanical failure is another potential reason for your air conditioner to freeze up. Any kinks in the system can lead to loss in pressure, or less than stellar operation, which often means the unit will end up freezing over.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Why_Has_My_Heat_Pump_Frozen_Over\"><\/span>Why Has My Heat Pump Frozen Over?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/why-hvac-unit-frozen-1.jpg\" alt=\"HVAC Unit Frozen | St. Louis HVAC Tips\" width=\"300\" height=\"240\" class=\"alignright size-full wp-image-3141\" \/><\/p>\n<p>While the above common causes cover the answer to your question: &ldquo;Why is my HVAC unit frozen even though it is summer?&rdquo;, your HVAC unit can freeze up in the winter as well. This often happens when there is a problem with your heat pump. While a little frost is common on heat pumps, a completely frozen heat pump usually indicates a serious problem and requires the attention of an HVAC professional. Some potential causes are:<\/p>\n<ul>\n<li>Malfunctioning defrost controls<\/li>\n<li>Malfunctioning defrost relay<\/li>\n<li>Damaged\/malfunctioning outdoor fan motors<\/li>\n<li>Low refrigerant levels<\/li>\n<li>Bad defrost sensors or thermostats<\/li>\n<li>Sticking reverse valve<\/li>\n<li>Unit needs leveling or elevation<\/li>\n<\/ul>\n<p>If you find your heat pump covered with frost or ice, shut the system off to prevent further damage, and call a trusted HVAC service for help.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Contact_Us_for_Help_with_Your_Frozen_HVAC_Unit_Concerns\"><\/span>Contact Us for Help with Your Frozen HVAC Unit Concerns<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Whether there is a problem with your air conditioner in the summer or your heat pump any time of the year, a frozen HVAC unit typically requires the attention of an HVAC expert.
