Furnace repair from LMH is a call away!

Take these steps to prevent an unneeded emergency call:

  • Does your system have power?
    • If you are using hand held remotes, check the battery, and replace them now.
    • Check your circuit breaker for your outdoor unit to ensure that you have not had a nuisance trip and your heat pump system does have power.
    • Check the outdoor disconnect typically mounted next to your outdoor unit to ensure that it is "ON".
  • Verify your system settings:
    • Make sure that at least one zone is set to "ON" and the desired temperature is set well below ambient for cooling operation, or well above ambient for heating.
    • If you are operating in the heat mode, 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 breaker was off, after turning the power on, give it a few minutes: many systems have a built-in time delay.
  • If your system is on, but not heating or cooling properly:
    • Check your indoor unit filters. If your filters have not been cleaned lately, clean them now.

After checking these items, if your mini split heat pump is still off or running improperly call us and we’ll dispatch a service tech to help. We always go the extra mile for every customer!

Common Mini Split Heat Pump Service Issues:

By far the most common cause of mini split heat pump problems is improper installation. We know how efficient and comfortable a ductless heat pump system can be, but if it's improperly sized, or improperly installed, they can fail to live up to your expectations. Common problems include:

  • Issues caused by improper installation:
    • Refrigerant loss due to improper installation or mechanical damage. This will result most commonly in reduced system capacity.
    • Improper zone sizing: If an indoor unit is too small it will fail to properly heat or cool in extreme weather. If it is too big, it will cycle on its lowest output and fail to properly dehumidify.
    • Condensation Leaks caused by indoor units installed out of level, or crimped or obstructed condensate lines.
  • Issues caused by lack or maintenance or component failure:
    • Changes in heating or cooling capacity over time caused by loss of refrigerant, or improper maintenance. Dirty indoor or outdoor coils.
    • Noisy operation indoors caused by a dirty filter or indoor coil.
    • Noisy outdoor unit may indicate a motor, compressor, or reversing system failure.
    • Outdoor unit fails to start may be cause by improper wire or breaker sizing, a tripped fuse, or failed outdoor component.
    • Indoor zone fails to start may be caused by loose or defective control wiring, or obstructed or failed IR receiver.
