There are few things better than entering a cooled down home on a boiling hot summers day. But what do you do when your air conditioner starts freezing up? How can you fix it? And can you prevent it from happening in the first place?


Check the Refrigerant Charge


When your air conditioners refrigerant charge is lacking fluid or altogether charged improperly, the entire unit may freeze up and stop working. So, when your air conditioner is suddenly freezing up, one of the first things you should do is look for leaks. Leaks can be caused by a number of things, including loose parts scraping against each other and loosening joints and fittings which allow fluid to leak out.


Thus, when you notice that fluid is running low, call a technician who can fix up leaks and refill the charge. Once that is done, they will also be able to provide you with a general maintenance of your unit so future leaks and freeze ups can be prevented.


Check Up on The Airflow


In order to keep the air in your home clean and your unit running, your air conditioner has a built-in filter. This filter will catch particles such as dust and pollen, which would otherwise clog up the AC’s parts and infiltrate your home. However, if you neglect to change the filter when needed, the air can become too dirty for the filter to keep up with, which means dirtied coils that will eventually stop working and cause the unit to drop in temperature until it freezes up completely.


This issue is easily prevented by changing the filter on a frequent basis. A recommended time frame is often given in the manual, but the make and model of the filter itself can also influence how frequently it needs to be changed. Simply check in with the manuals and stick to the given schedule. It is important to call in the HVAC experts in Philadelphia to look over the requirements.


Remain Mindful Of Outdoor Temperatures


While there are things that can happen to raise the indoor temperature even while it is cold outside, there are limits for what your AC can handle. Your workout may have warmed you up, your cooking or baking may have brought sweat to your brow, but when the outside temperature is below sixty degrees, you should never switch on the AC. Your air conditioner unit will likely freeze up under such conditions, simply because they aren’t built to work while the outdoors is so cold. When switched on, the below sixty degrees air from outside will wash across the unit’s coils and cause them to freeze.
