I visited a long-term customer recently to review their existing systems.  We talked extensively about the equipment they have and the maintenance that they receive each year.   One piece of equipment

that had not been serviced was their Mini-Split system for which they absolutely love and was the reason for my visit.


More homeowners are installing mini-split systems, and that’s a good thing. Not only are mini-splits more efficient than typical air conditioning systems, but they’re also extremely practical for home additions, outbuildings, and even troublesome rooms that never seem to be hot or cool enough.


But as neat as mini splits are, they’re still, you know… HVAC systems. They can break down.


During the summer, we often get calls from mini-split owners with units that have stopped cooling. Here’s a step-by-step process for fixing this problem and how to minimize its recurrence down the line.


Troubleshooting:  Sometimes, there’s nothing wrong with your mini-split. You just need to do some basic troubleshooting to fix the problem. Here are some steps you can take:


  1. Check the thermostat batteries. They might be dead. Pop in some new ones and your AC should start right up.
  2. Reset the circuit breaker. Head over to the breaker box and see if any of the breakers have tripped. If one has, check for shorts in the wiring connected to that circuit. If there aren’t any shorts, set the breaker back into place. Your mini-split might start working again. If the breaker keeps tripping, consider whether other devices or equipment are connected to the same circuit as the mini-split.
  3. Check for ice on the coil. The system can shut off if the airflow is so restricted that ice forms on the AC coil. In most cases, ice on the coil means it’s well past the time you changed your air filter. If there’s ice on the coil even though the air filter is clean, you may have other problems that require an HVAC professional.


Is the mini-split still not cooling after you completed these troubleshooting tasks? Now’s the time to call a pro.
