Why Is My Air Conditioner Freezing Up?

You may not realize how much you miss your air conditioner until you no longer have it at your disposal. If that occurs during those particularly sweltering summer months from May to September, you are going to be miserable. Period. So that’s why it’s a good idea to ensure that your air conditioner is in excellent working condition when you really need it. That means having even the smallest problems diagnosed early, before they become a bigger issue.

Among the more common problems that may not seem all that urgent at first glance (but can turn into serious and costly matters down the road) is an accumulation of frost on various components of your air conditioning system. But HVAC repairs Tulsa can get very expensive when issues are left unaddressed and when it comes to your AC freezing up, you should be well aware that you may be facing a pricey repair bill if you refuse to deal with the matter as soon as possible. Just like with your heating bill, you want to pay less to run your AC. If the system is freezing up, you could be dealing with an efficiency issue. Simply put, your unit should not be freezing.

The truth of the matter is that any evidence of frost on your air conditioner is a red flag that it’s not working properly. You could be jeopardizing your HVAC system as frost can lead to damage of the components upon which that frost has developed. But it’s the reasons behind that frost buildup that should be fully understood, so you can fix these issues promptly and avoid the high cost of repair or even replacement.

Blocked Airflow

All air conditioners require sufficient airflow in order to do the job required of them. If that airflow is blocked for any reason, it can lead to water freezing over in the evaporator coil and the temperature in the coil falling to the freezing mark.

A common fix for this problem is replacing your air filter. Doing this not only eliminates the contaminants that can reduce your air quality, but prevents them from being re-released into the air after the filter becomes inundated with such particulate. But even more important, a clean filter allows for air to go through the system unabated and preserving the lifespan of your air conditioner.

Lower Temperatures

You should be cognizant of when you operate your HVAC system, particularly when the temperatures are lower outdoors. Frost can accumulate on your unit if the thermometer gets below 60 degrees and that can happen more often in the evening. So, the best thing to do is shut the system down until the morning when the sun comes back up.

Low Refrigerant

In order for your air conditioner to work, it needs refrigerant. When there isn’t any in the system, it’s unable to absorb heat properly and freezing occurs. But the thing about refrigerant is that it’s not consumed by the system, so a shortage means there could be a leak some place.
