Practically every week, one of our heat pump specialists arrives on a repair call only to find out that the problem was simple and might have been easily corrected by the owner. Before you call us, check these items to ensure you really need our professional services:

  • Remote Control Batteries: If your mini split heat pump uses a hand-held remote, check, and perhaps change the batteries.
  • Check Operating Mode: Check to make sure your system control is set to the correct mode: generally "Cooling" in summer and "Heating" in winter.
  • System Calling for Heating or Cooling? 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 operation.
  • Is the Power On? Check your circuit breaker to ensure that you have not had a nuisance trip and your heat pump system does have power.
  • Is the Outdoor Unit in Defrost Mode? If you are operating in the heat mode, make sure that your system is not in “Defrost” mode. If it is, "defrost" should complete within a few minutes and heating operations should then resume.
  • Time Delay: If your breaker was off, after turning the power on, give it a few minutes - many systems have a built-in time delay.
  • Air Filters: Check your indoor unit filters. If your filters have not been cleaned lately, clean them now.

After checking these items, if your ductless mini split system is still on the fritz, or shows no signs of operating correctly don't hesitate to give us a call. We'll send one of our certified heating and cooling technicians out to your property to properly diagnose and fix your issue!
