    • Power Supply:
      • First, check your circuit breaker for your outdoor unit to see that you have not had a power trip and your heat pump system does indeed have power.
      • Next, check the outdoor disconnect which is usually mounted next to your outdoor unit to ensure that it is on.
    • Efficient Air Moving: Old school air conditioning utilized inefficient single speed PSC motors for the indoor fan motor and the outdoor condenser fan motor. Armstrong offers two new more efficient motor systems:
      • ECM Variable Speed Motors can provide a broad range of airflows based on system requirements for better comfort and air quality while using less energy than other motor types.
      • Constant Torque Motors are higher efficiency, brushless DC motors that are designed to provide a given rate of airflow (CFM) even when operating conditions like static pressure change.
    • Check your zone controls:
      • Next, check that your devices remote has good and full batteries, if they are dead replace them.
      • Then, set one of your spaces zones to on, and if you’re trying to cool set the temperature well below the ambient temperature, or well above for heating.
      • If you are trying to heat, make sure that your system is not in “Defrost” mode. If it is wait a few minutes for your system to complete its defrost cycle.
      • If your circuit breaker was off, after turning the power on, give it a few minutes, because many systems have a built-in time delay which will affect operation.
      • If your system operating, but not performing properly:
        • This could be a filter problem, check your heat pump filters and clean them if they are dirty.
        • If it’s winter and you are heating, make sure the outdoor unit doesn’t have snow or ice on it.

Common Mini Split Repair Issues

The most common cause of mini split heat pump failures, or customers that are dissatisfied with their operation, is improper installation. We know how great a mini split heat pump unit can be, but if its improperly sized, or improperly installed, it can fail to live up to its potential. Here are things to look for:

  • Refrigerant Loss: Due to improper installation or mechanical damage. This will result most commonly in reduced system capacity.
  • Outdoor Unit Fails to Start: Caused by improper wire or breaker sizing, or failed outdoor component.
  • Indoor Zone Fails to Start: Loose or defective control wiring. Obstructed of failed IR receiver.
  • Changes in Heating or Cooling Capacity: Caused by loss of refrigerant, or improper maintenance. Dirty indoor or outdoor coils
  • Condensation Leaks: Caused by indoor units been out of leave, or crimped or obstructed condensate lines.
  • Noisy operation Indoors or Out: May indicate a motor, compressor, or reversing system failure.
