A Ductless Mini-Split Troubleshooting Guide for Wilmington, NC

No matter how vigilant you are about scheduling regular maintenance calls for your ductless mini-split in Wilmington, NC, it’s normal for your unit to develop minor issues over time. The list below can help you understand the most common ductless mini-split problems and how to fix each one.

Wiring Problems

If your ductless mini-split doesn’t turn on, you might have tripped a circuit without realizing. Give your circuit breaker a quick look. If everything looks OK there, see if the unit’s cord has any damage.

Issues With the Unit’s Power Supply

Most ductless mini-splits use a power supply that plugs into the wall, and they don’t typically have backup batteries to take over if the circuit they’re attached to goes out. If you’ve already made sure that you have adequate electric power flowing to the unit, your power supply may simply be dead. A good warranty should cover a replacement, and the best manufacturers will ship you a new one right away.

Leaking Refrigerant

Bugs and inclement weather can wear down the cables that carry your system’s refrigerant between the outside and the inside of your home. When this wear and tear gets bad enough, these cables can spring a leak. A refrigerant leak can threaten your whole HVAC system, but it’s usually not a hard problem for a professional to fix if you catch the leak soon enough.

Clogged Drain Line

You can keep your drain line clear by pouring a little vinegar down it once every two months. The vinegar eats through dirt and debris trapped inside of the line, but it doesn’t damage your plumbing.
