      When the homeowner calls and tells me about their often needing to reset the heat pump breaker or that the HP won't even start I perform a comprehensive 240v and 24v circuitry electrical check. Many times the starting amperage is 150% of the design LRA rating, the compressor windings are good and not grounded, there is no start capacitor, and the dual run capacitor is weak. With a new dual cap and the correct sized CSRU compressor saver kit installed the starting amperage usually drops to only 50-75% of LRA rating. I've been called in to troubleshoot several HPs after HVAC contractors have said to the homeowner, sometimes even after they unnecessarily replaced the compressor, "I don't know what else to try". The 3-wire designed CSRU unit is far superior to a 2-wire hard start kit and is very easy to install. It gets to be a "no brainer" to install one (after having checked compressor windings and ground, the dual run cap, and the 240 and 24 volt circuitry). If it doesn't resolve the excess current draw problem its just as easy to remove it....
