Troubleshooting Your Cincinnati Ductless Mini-Split System

Ductless mini-spit heat pumps are used in Cincinnati homes and businesses to provide efficient year-round comfort. Depending on your system configuration, there may be multiple ductless air handler units installed throughout your home or commercial building to provide zoned heating and cooling. Should one of your ductless units stop working, there are a few troubleshooting steps you can perform which may restore system functionality without professional assistance.

  1. Check power sources

Because mini-split air handler units are often installed up high and out of the way, your system may come with a remote for easy control. If a unit is not working, the issue may not be the unit, rather the remote may be to blame. Replace the batteries with new ones to see if this resolves the problem.

If the circuit breakers on the unit’s circuit have tripped, the unit will not be powered; you’ll be able to see that the unit isn’t receiving power because its display will be off. Check your electrical panel to see if any breakers have tripped; reset them to restore power. If your ductless heat pump causes the breaker to trip repeatedly, electrical repairs may be necessary.

  1. Adjust temperature settings

Sometimes, the source of a ductless unit not starting up is as simple as an improper temperature or system setting. Check the display panel to verify that the correct mode has been chosen – heating for winter, cooling for summer – and that the temperature setting is low or high enough to trigger the system to fire up. To initiate cooling, set the ductless mini-split’s temperature a few degrees below the current room temperature; for heating, set the temperature slightly above current room temperatures.
