What happens if ac freezes

Leave it to our technicians and keep yourself away from handling them if possible. Obstructed airflow can keep the coils from properly cooling and lead to a frozen AC unit.

Another good practice is to walk around your home and check that indoor air vents and registers are clear from any obstructions.

Your ducts are how air moves through the house so if something blocks the duct, naturally air stops flowing correctly and this can block airflow to the coils.

Even if the rest of the system is running smoothly, a collapsed or blocked air duct in your home or more than one duct can cause your AC to lose airflow. The blower motor, naturally, matters a great deal in this system. And once that air stops blowing, the coils start freezing.
