When Your AC Freezes Up

When Your AC Freezes Up

One of the worse things to every experience during a Houston, Texas hot, humid summer is finding a huge puddle surrounding the inside portion of your air conditioning system.  The first thought that flies through your head is how much will this cost or what did it have to happen on the hottest day of the summer?


There are a few ways that you can try to solve this issue yourself.  First part, is knowing what and why your air conditioning unit has frozen over.  It is the component, called the evaporator coil, that is in charge of transferring heat from the inside of your home to the outside part of the air conditioning system.


There are two most common reasons as to why your evaporator coil has frozen over.  The first is airflow restriction, and the other insufficient refrigerant.  These affect your evaporator coil from working properly.  It causes condensation to form on it that eventually freezes over, thus creating its own icebox.


First thing that you need to do to unfreeze your evaporator coil is by turning your AC system completely off using your thermostat.  Do not try to thaw out the evaporator coil by turning the heat on and raising the temperature.  That will not work, but shutting it completely off.


Next you need to make sure that there is nothing blocking or preventing a consistent airflow to your air conditioner.  You simply just need to check both your furnace, air handler, and air filters.  Make sure that they are not dusty or filled with tons of debris.  Make sure that all of the registers throughout your home are open and not blocked by furniture or other items.


After that, it is always best to call a professional, like Autumn Mechanical right here in Houston, Texas, to make sure that your air conditioner system is not leaking any of the refrigerants needed to cool the air down or that any other parts are damaged.


From there, the specialist should be able to help you figure out exactly what the issue is and find the right solution for you.  They can also help you from preventing this happening again.  It is best to make sure that any damages or leaks are taken care of right away to this does not repeat itself again.


There is one last problem that could be causing your AC system to freeze up, and that involves your air conditioning unit outside.  If the outdoor temperatures get to where they are below 60 degrees F at night, then this can cause your system to not run properly and cause it to freeze up.


If this happens, turning off your system when you notice the drop in temperature or looking at investing in installing a special ambient temperature control.  That will help allow the system to operate properly under temperatures less than 60 degrees F.
