Inverter Board Repair | How We Approach It

Unlike older AC systems that simply turn on or off, mini splits use advanced 'Inverter' technology to ramp up and down smoothly. This is controlled by a complex circuit board inside the outdoor unit. Unfortunately, these boards are highly sensitive to power surges, brownouts, and lightning strikes. A fried inverter board will completely lock out the compressor. Our technicians are specially trained to use multimeters and diagnostic flowcharts to trace electrical faults down to the specific circuit board and safely replace it.
