The answer to 'why is my mini split not turning on' is that there could be several common causes, including a tripped circuit breaker, a faulty remote control, or issues with the outdoor unit. Mini splits are a type of ductless HVAC system that provide heating and cooling without the need for ductwork. If your mini split is not turning on, it's important to troubleshoot the issue to determine the root cause.
One of the most common reasons a mini split may not turn on is a tripped circuit breaker. Check your home's electrical panel to see if the breaker for the mini split has been tripped, and reset it if necessary. If the breaker continues to trip, there may be an underlying electrical issue that requires the attention of a professional HVAC technician.
