A frozen air conditioning unit isn’t a good thing; it’s an indicator that something may be wrong with the unit’s internal parts. You might think that it’s a testament to how cold the machine is, but you’ll actually notice that the air it’s pumping out is warmer than usual.
It’s difficult to determine what causes the AC unit to freeze over and start building up ice and frost. But, there are warning signs you need to watch out for and address immediately before the machine starts freezing over.
Warm Air and Leaks
If you notice that your air conditioning unit seems to be expelling relatively warm air, then it’s a telltale sign that there’s something blocking the flow of air within the vents. Since the cold air can’t escape properly, it remains within the internal structure of the AC unit itself, which eventually causes the parts to freeze.
The situation becomes worse when your AC unit starts leaking. Since the temperature inside the machine is already very cold, the leaks will eventually freeze. When this happens, ice starts building, blocking the passageways further and may even physically damage the pipes and vents inside the air con unit.
Dirt and Debris
It’s also a good idea to check if the internal parts of the AC unit, particularly the evaporator coil, are dirty and full of debris. The evaporator coil is technically what manages the flow of air and when it’s dirty, it retains the air it’s supposed to expel. This eventually causes a drop in temperature that leads to freezing.
Clean your air conditioning unit to prevent this from happening, and make it a habit to change the filters at least once every week. You’ll avoid causing dirt and debris build-up and make sure the air is safe to breathe.
