Do you have a soft start on your a/c? Even if it will start your condensing unit, our inverters will last longer if they're not loaded with that inrush current every single time. Plus it is better for your compressors, contactor inside the unit, wiring, terminals breakers, etc 25-30% the inrush current. Two of my hvac systems are fully variable speed, the other two have standard PSC compressors, so they got the soft starters. I don't know if my little 2 ton PSC and 1.5 ton PSC compressors would have caused any problems or not.
