Understanding And Repairing A Frozen AC Unit
It is important that your AC unit helps cool your home, but it does not need to freeze up to do so. Basically, a properly working system removes warm air from the home's interior, converts it to cool air, and then transfers it back into the home. If, during this process, a frosty residue builds up on the actual AC unit, there is a problem to address.
In most cases, a frozen AC unit will not be able to produce or move cooled air into the home, reducing your family's comfort.
