Frozen Unit in the Summer | HVAC Tips

A frozen AC or heat pump unit usually means either dirty filters blocking airflow or a refrigerant leak. Clean your filters first. If that doesn't fix it, call a technician to find the leak and recharge the system.

One is airflow. We talk a lot about checking, changing your filters inside your return. The reason is because your unit needs to breathe. So when it cannot breathe, it's going to frost up, freeze up, and stop working because now it cannot breathe. Another common aspect of the freezing unit is it's low in refrigerant. We kind of hit refrigerant pretty hard a few weeks ago. But you shouldn't need to add refrigerant every year to your unit. And if it's leaking out, if the unit is frozen, then obviously we need to find the leak and fix the leak. The unit itself is not just going to run low on Freon all of a sudden, or, or use the Freon it's been using for 10 years and all of a sudden it needs 2 pounds. Obviously something has changed, it has leaked out somewhere. We need to find that leak. Stop it from happening, charge it back to the proper amount, and then you'll be good to go. But the freezing is usually caused by refrigerant and by airflow. So, uh, a thing I would do myself if I saw it freezing up or frozen is to make sure my filters are clean and nothing is stopping the airflow. If everything's good there, then I would call and have a technician come out and check it, because most likely you are low on refrigerant. Or again, you could have another airflow problem of, you know, the blower motor, things like that not working, uh, things you cannot do yourself. But the filter is something you can do yourself, so check that and make sure it's good to go. If it is, then call a professional.
