Use this troubleshooting guide to help you identify the problem. Then take any necessary steps that can be done from your end or call Berico for assistance.

  1. Low air flow. Your air conditioner requires sufficient flow of air through the system in order to work correctly. The air that comes in and goes out passes over an important part called the evaporator coil. The coil is full of refrigerant that cools air down and transfers warm air out as it passes to keep your home cool and comfortable.

Possible reasons for low air flow:

  • Clogged filters. Check your filters and replace them if necessary. Consider changing your filters monthly to achieve maximum air flow.
  • Blocked or leaky ducts. Have a professional HVAC company check your ductwork for any blockages or leaks that may be interfering with proper air flow through your system.
  • Blower failure. If the blower is not properly moving air over the evaporator coil, it can cause ice to form.
  1. Low refrigerant. The evaporator coil must contain a very specific amount of refrigerant to properly cool incoming air and remove heat from outgoing air. If there is not enough refrigerant, it can cause your AC to freeze up.

Possible reasons for low refrigerant:

  • Leaky coil. If there is a leak somewhere in the coil, the refrigerant level will be too low to transfer heat out and cool down the incoming air.
  • Refrigerant line kinks or leaks. If there are any leaks in your system where refrigerant is getting out, or if there is a kink in the refrigerant line, it leads to an insufficient amount of refrigerant in the coil.
