The startup current for most correctly operating blower motors is low (usually less then 200% full load amperage), so the OP's concern should not be much of an issue. If it is a premium efficiency system it might use an ECM motor, which is electronically managed and also has a low startup current. If one cares to measure it oneself, no special inrush meter ...


Measuring the startup load is as easy as using a clamp on meter and turning the air handler on and off. The startup load will be high for a split second, then drop down to a steady load. Use Ohms Law to calculate the wattage. Watts/Voltage = Current As mentioned in my comment, the invertors peak load is a good indication of the invertors motor starting ...
