It\u2019s a great investment for your home, sure, but now you\u2019re dealing with this headache of a problem. Your evaporator coils just froze over and you\u2019re not sure what to do about it\u2013let us help you.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"\/hvac\/heating\/heat-pumps\" target=\"_blank\" rel=\"noreferrer noopener\">Heat pump service in Morton Grove, IL<\/a> will find the underlying cause and treat it, but before that happens, it\u2019s important to know what causes a complete system freeze so you know what to look for in the future. Let\u2019s talk about that.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\">These Are the Issues Your Heat Pump Might Be Facing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If your heat pump is freezing, it could be from a few different underlying causes. If it freezes over and you let it thaw, there could still be mechanical damage (plus that doesn\u2019t determine what caused it in the first place). We implore you to get a professional inspection on your heat pump so you know what to avoid in the future.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Dust Insulation: <\/strong>When you have bad airflow, it can lead to dust building up on the evaporator coil. This dust acts as an insulation, and doesn\u2019t let warm air interact with the refrigerant like it normally does.<\/li>\n\n\n\n<li><strong>Poor Airflow in General: <\/strong>Even if dust isn\u2019t getting into your heat pump (no more than usual, anyway), poor airflow can still cause other issues. If airflow is restricted in any way, your heat pump will struggle to carry out its normal function. That means more strain, and more power draw, which will expedite any issues that it\u2019s facing.<\/li>\n\n\n\n<li><strong>Low Refrigerant Levels: <\/strong>Heat pumps operate on a closed loop system. That means that refrigerant circulates in a loop and doesn\u2019t leave the system. Ever. If your refrigerant levels are low, it means there\u2019s a leak. When levels lower, it impedes upon the function of your evaporator coil, causing it to freeze up.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Here\u2019s How to Proceed<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Your heat pump has you in a bit of a bind. This is what you need to do next and what it means for your heat pump.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Call for Repair: <\/strong>Repairs act as a point of inspection, so a technician can inspect all the components of your heat pump, determine if there\u2019s any damage, and tell you if it\u2019s safe to continue operating as-is.<\/li>\n\n\n\n<li><strong>Schedule Maintenance in the Future: <\/strong>Your heat pump should already have annual maintenance, but if it doesn\u2019t, now\u2019s the time to schedule it.<\/li>\n\n\n\n<li><strong>Be Vigilant: <\/strong>Look for drainage problems, poor airflow, warm air coming from your vents, and anything else that indicates your heat pump isn\u2019t working properly. The sooner you catch a problem, the better it will be when it comes to repairs.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">It\u2019s Time for Heat Pump Service<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A frozen heat pump isn\u2019t just ironic; it\u2019s frustrating. We get it, which is why we want to emphasize the importance of not only getting professional repairs, but keeping a maintenance schedule for the future. Keep your heat pump in top form from here on out.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Frequently Asked Questions<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Question: Why is my heat pump freezing up?<\/strong><strong><br><\/strong><strong>Answer:<\/strong> A heat pump can freeze when restricted airflow, dust buildup on the evaporator coil, or low refrigerant prevents the system from transferring heat properly. Low refrigerant usually indicates a leak, while airflow problems may come from dirty components or other restrictions that interfere with normal operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Question: What should I do if my heat pump freezes over?<\/strong><strong><br><\/strong><strong>Answer:<\/strong> If your heat pump freezes, schedule professional repair so a technician can inspect the system, identify the underlying cause, and check for any resulting damage. Simply allowing the ice to thaw does not solve the original problem and may leave mechanical issues unaddressed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Question: Can poor airflow cause a heat pump to freeze?<\/strong><strong><br><\/strong><strong>Answer:<\/strong> Restricted airflow can cause the evaporator coil to become too cold because it is not receiving enough warm air to support normal heat transfer. Poor airflow also forces the heat pump to work harder, increasing energy use and placing additional strain on the system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Question: Can low refrigerant cause a heat pump to freeze?<\/strong><strong><br><\/strong><strong>Answer:<\/strong> Low refrigerant can interfere with the evaporator coil\u2019s ability to operate correctly and may cause ice to form on the system. Because heat pumps use a closed refrigerant loop, low refrigerant levels generally indicate a leak that requires professional diagnosis and repair.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Question: How can I prevent my heat pump from freezing again?<\/strong><strong><br><\/strong><strong>Answer:<\/strong> Regular maintenance can help identify airflow restrictions, drainage problems, refrigerant issues, and other conditions before they lead to another freeze-up. Homeowners should also watch for weak airflow, unusual system performance, or warm air from the vents and schedule service when problems appear.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><a href=\"\/contact\/send-message\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Contact Roberts Heating &amp; Air Conditioning, Inc. today<\/strong><\/a><strong> to schedule your heat pump repair and ongoing maintenance appointments.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Is your heat pump freezing like a popsicle?
