However, there are times when the process can go wrong, making the A\/C freeze. There are several potential causes, which can be related to airflow or refrigerant issues. <\/span><span style=\"font-weight: 400;\">These are some of the most common causes of A\/C freezing:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><b>Dirty coils <\/b><span style=\"font-weight: 400;\">&#8211; An A\/C normally pulls water out of the air to dehumidify it. This is how condensation builds up on the coils. Although this is not usually a problem, dirt inside can keep the coils from absorbing moisture. Eventually, the water can build up and freeze over the coil. Regular inspections by HVAC professionals can prevent the buildup of dirt. <\/span><\/li>\n<li style=\"font-weight: 400;\"><b>Drainage problems <\/b><span style=\"font-weight: 400;\">&#8211; Normally, water from the evaporator coils drip into a drainage pan and out a drain. If the drain is blocked, the water can freeze and back up to the evaporator coil. As the water freezes, the drain becomes further blocked, which can escalate the problem.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/www.drduct.net\/wp-content\/uploads\/2018\/08\/2air-conditioner.jpg\"><img decoding=\"async\" class=\"size-full wp-image-1363 aligncenter\" src=\"https:\/\/www.drduct.net\/wp-content\/uploads\/2018\/08\/2air-conditioner.jpg\" alt=\"air-conditioner\" width=\"640\" height=\"423\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\"><b>Low refrigerant levels <\/b><span style=\"font-weight: 400;\">&#8211; If your A\/C lacks refrigerant, the pressure difference in the system causes moisture to condense on the evaporator coils. Condensation normally forms outside the lines. However, the lack of refrigerant brings the temperature to lower than normal levels. Eventually, the temperature will drop, freezing over the coils. <\/span><\/li>\n<li style=\"font-weight: 400;\"><b>Poor airflow <\/b><span style=\"font-weight: 400;\">&#8211; A dirty air filter can affect the flow of air to the A\/C. The airflow brings in heat from inside so that the system can cool the room. If there isn\u2019t enough air flowing through the system, heat exchange can\u2019t take place. The coils are designed to have humid air pass over them to prevent freezing. Without proper airflow, however, the moisture will eventually freeze. <\/span><\/li>\n<li style=\"font-weight: 400;\"><b>Damaged blower fan <\/b><span style=\"font-weight: 400;\">&#8211; An air-conditioning unit has a fan as part of the system to suck hot air away and replace it with cold air. If the fan doesn\u2019t work properly, the airflow becomes disrupted. Cold air can\u2019t flow properly, causing temperatures inside the system to drop. Eventually, condensation on the coils can freeze. The freezing can spread to the refrigerant line and affect the condenser unit outside. <\/span><\/li>\n<li style=\"font-weight: 400;\"><b>Thermostat issues <\/b><span style=\"font-weight: 400;\">&#8211; A faulty thermostat can cause problems during cold nights. In these cases, the A\/C is left running, even when it shouldn\u2019t be. Not only can this freeze the system over, it wastes energy and money. Have the thermostat checked regularly to ensure that everything is running smoothly. <\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Your air-conditioning requires regular maintenance to run smoothly. Contact a professional HVAC service to ensure that everything is operating as it should, preventing costly repairs in the future.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/www.drduct.net\/wp-content\/uploads\/2018\/08\/3commercial-air-conditioning.jpg\"> <img alt=\"Why Is My A\/C Freezing?\">  class=&#8221;size-full wp-image-1365 aligncenter&#8221; src=&#8221;https:\/\/www.drduct.net\/wp-content\/uploads\/2018\/08\/3commercial-air-conditioning.jpg&#8221; alt=&#8221;&#8221; width=&#8221;640&#8243; height=&#8221;360&#8243; \/><\/a><\/p>\n<p><span style=\"font-weight: 400;\">At Dr. Duct, we are committed to providing <\/span><a href=\"https:\/\/www.drduct.net\/services\/air-duct-cleaning\/\"><span style=\"font-weight: 400;\">air duct cleaning<\/span><\/a><span style=\"font-weight: 400;\"> to for clean, healthy airflow.
