Do you need our help?

Surprisingly often one of our air conditioning service tech's arrives on a service call only to find out that the problem was simple and might have been easily identified by the owner. Before you call us, check these items to ensure you really need our help:

  •   Check the Batteries: If your mini split heat pump uses a hand-held remote, check, and perhaps change the batteries.
  •   Hand Held Remote or Thermostat Set Properly? 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.
  •   Check Your Power Supply: Check your circuit breaker to ensure that you have not had a nuisance trip and your heat pump system does have power. Also check the outdoor disconnect to make sure it is on.
  •   In Heat Mode, Is Defrost On? If you are operating in 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.
  •   Consider the 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.
  •   Check the Air Filters: Check your indoor unit filters. If your filters have not been cleaned lately, clean them now.
