Troubleshooting Ductless Mini-Split Units in Cincinnati, OH

Ductless Service Professionals | Nelson Comfort

Ductless mini-split systems are a popular option for Cincinnati home and business owners, as they provide year-round comfort, functioning as both a heating and cooling system. Many homes and businesses are set up with multiple air handlers to create a multi-zoned comfort system. If an air handler in your Cincinnati home or business stops working, here are some troubleshooting tips you can try before calling us for service.

Check your remote

Since ductless mini-split systems can be installed high upon a wall or even inset to the ceiling, they typically come with a remote for easy control. If you use the remote, and it doesn’t seem to be working, try to operate the unit with the control buttons on the unit. If the air handler can be operated with the buttons on it, there may be a problem with your remote. Often, it’s the batteries, so replace them to see if that corrects the problem.

Adjust your settings

If the air handler’s temperature setting isn’t higher than the current room temperature, they system won’t be triggered to run a heating cycle. Check to see that the temperature is set a few degrees higher than room temperature, and adjust if necessary. Also, make sure the unit is set to heating mode – mistakenly setting it to cooling mode will cause it not to operate.

Inspect your electrical panel

If lights on the air handler are dark, the unit may be without power. Check your home or business’s electrical panel to see that the unit’s circuit breaker has not been tripped. If it has, reset it and attempt to turn the air handler on. If the unit’s breaker continues to trip, there could be a problem with the electrical connections or wiring, which should be handled by professionals.

If these troubleshooting tips fail to get your ductless mini-split air handler back up and running, call Nelson Comfort for quick and reliable heating repair. Our NATE-certified ductless mini-split technicians are available 24/7 to solve your heating problems this winter.
