I have a 5 ton Heatpump thats less than 1 year old. I have the Flikering light problem that comes with compressors. Power company has been out and they are sound. I just need to install a starter kit. Where do I get one? I went to Johnstone but they sold me something the size of an old film canister (showing my age now) seems to small for the job. Model #H2H360GKA100
5-2-1 Hard Start Kit aka comrpessor saver. Note the tonnage, one size for 3.5 through 5. You can find them on Amazon or at your local hvac supply house. Pretty sure Johnstone has them and if what's pictured is what they gave you then that's it.
