You can try adding what's called a "hard start capacitor" to your compressor. They're super simple to install, two wires and you're done. If your compressor is not quite up to the task of your system, the hard start might get things going smoothly again.

I'm not sure where you'd get it, though. Johnstone is my supplier but I'm in the trades and they work with me - Johnstone doesn't generally sell to the average Joe. Look in your yellow pages under electric motors and ask around.
