An air conditioner that “freezes up” is actually a victim of the A/C coils freezing up. As a result, homeowners may find themselves without any air conditioning, and will need to troubleshoot the system or call a pro.
When A/C coils freeze, there could be a simple solution to the problem; however, more complicated scenarios may have caused the freezing. Before you call a pro, it pays to investigate the source of the problem.
The evaporator coil is prone to freezing, primarily because it transfers heat, or evaporates it, from the indoor to the outdoor air. In the process, it also drains a lot of condensation. When problems occur, this condensation can form a block of ice around the coil, causing it to freeze. At this point, the air conditioner won’t work anymore.
Four primary factors lead to the A/C coils freezing up:
Regardless of the cause, frozen coils prohibit heat from dissipating as it moves over the coil, the coil becomes overcooled, and condensation and ice can form. Follow these steps to troubleshoot coil freeze:
If the problem does not resolve itself, other factors to consider include:
In the case of a wet filter, dirty coil or low refrigerant, it’s best to let a professional diagnose the problem.
