An air conditioner should never freeze up. If you notice that your air conditioner is freezing up or frost on the lines, it is an indication that something is wrong. Most freeze-ups result from restricted airflow, a clogged or plugged filter, or closed or blocked vents. It can also be a result of low refrigerant or an internal restriction within the system. Whatever the underlying issue, you will need a qualified technician for a proper diagnosis and repair. Contact our technicians at (801) 262-4671 to set up an appointment.
