Why Do AC Units Freeze Up?

Here’s the situation: you’re enjoying your AC unit. Your Lincoln home is comfortable and everything is right in the world. Then, suddenly, you find that your air conditioning unit is malfunctioning and what once was a pleasant home environment is now an uncomfortable hell-scape. It’s happened— your AC unit has frozen over. When something like this happens, it’s easy to get frustrated and wonder where the problem lies. At Wellmann Heating & Air, we want to make sure you not only get great AC repair but also know the facts about why your AC unit has frozen over. Once you know where the problem is coming from, it becomes easier to fix.

One reason AC units can freeze up is due to refrigerant issues. Refrigerant is a substance that helps to cool your air conditioning unit to make sure it doesn’t overheat. However, in some cases, too much refrigerant can cause a drop in temperature for your AC unit. The best solution is to call Wellmann Heating & Air and schedule an appointment to check the refrigerant levels in your AC unit. Keeping up with regular maintenance can make sure that you don’t end up with too much or too little refrigerant in your air conditioning unit.

Another thing that might be causing the freeze over is improper air flow. This can be caused by debris in your AC unit, duct leaks or dirty filters. When these obstructions hinder the air flow of your air conditioning unit, they can cause the refrigerant to pick up less heat and therefore lower temperatures. To combat this, make sure to keep your AC unit as clean as possible with regular air conditioning maintenance, including replacing air filters, cleaning ducts and coils as well as sealing all leaks.

Making sure your AC unit is kept working is Wellmann Heating & Air’s most important task and we want to help you understand the problem as well as the solutions. Call us today and get the comfortable home environment that you deserve!
