You expect your furnace to be warm. You count on your air conditioner to be cold — but not below freezing. Unfortunately, the internal workings of your system may not cooperate the way you’d expect. If things go wrong, you may end up with an iced-over system. To prevent an HVAC freeze-up, learn what causes this problem so you can take steps to avoid it.

Obstructed Airflow

Your system depends on airflow. If the air can’t move freely, then there’s a good chance that your HVAC will freeze up. Dirty coils are one common culprit. An old filter that needs to be changed is another. Closing too many vents throughout your house can mess up the flow, as well. Also, weakening ventilation pipes may develop sags or bends that disrupt the system.

Refrigerant Leak

Coolant regulates the temperature of your HVAC system. If the level gets too low, it won’t be able to do its job. A leak is the most likely explanation for the low refrigerant. Adding more coolant can help, but you’ll also need to schedule leak repairs.

Improper Temperature Settings

Your HVAC system is powerful. However, if it’s in need of repair, it can’t achieve any temperature you want. If you drop your thermostat quite low, your air conditioner may not be able to handle the job. Freezing up may be the response.

Electrical Problems

The wiring inside your HVAC system is incredibly important for proper operation. If the connections come loose or the wires fray, problems can develop. For example, your blower motor may not work efficiently or consistently. Without its contribution to the system, freezing may occur. Annual tune-ups are useful for catching electrical problems early.
