I am switching out my capacitor and could only find a dual run capacitor locally. I would appreciate any help on wiring it. The previous capacitor wasn't a dual run capacitor. Please see attached photos of existing capacitor and new capacitor. I really appreciate any help on how I wire the new capacitor.

I seem to have a freon leak someplace in my AC system. I had freon refilled and it worked well and kept my home cool for about 2 months and after that it kept warmer and warmer. AC runs, but it's just not keeping the inside of home cool enough. I kind of suspect that the leak is inside the home on the evaporator coil because if it did freon would have leaked inside my basement and spread to the rest of the home, and I would have gotten sick from inhale freon I believe (please correct me if I'm wrong). I suspect the leak is most likely on the outside unit. I met with some techs and sale reps from HVAC contractor businesses, and they all said like "since the AC system is 13 years old, we don't recommend investing in fixing the leak. If you decide to fix the leak, it will cost any where from about $800 to $1,800". I'm leaning toward getting AC system replaced, but my dilemma is all these AC contractors want me to sign the contract, and on the day of the AC replacement, if a leak is found on the copper lines following nitrogen test, then another quote will be provided. The majority of my copper lines are buried in the drywall ceiling which would make replacing the copper lines more difficult and expensive. On my drywall ceiling where the copper lines run, I don't see any stains which I suspect would be present if the leak is on the copper line. What would be the best thing to do? Finding a leak alone seems to cost anywhere from $400 to $1,000 the cost of which I would like to avoid if I can be reasonably sure if leak is not on cooper lines. Your opinions?
