I an appreciate that. I've been a Dometic Marine AirConditioning servicing dealer for 15 years, so I do know a little bit about it myself. If you read enough of these threads on various forums it will become evident that there are a lot of people offering air conditioner advice that do not know a thing about it. Everyone's solution is a hard start kit or a run capacitor, or it needs freon.
The rooftop units that the manufactures decide need start components already have them. If they do not, it's because the design engineers decided that because of low starting amperage, or whatever, it's not needed. Occasionally, a compressor in a system that does not contain one will develop a need it. That's usually is because of something changing in the compressor or it needs a little help with a generator. What most people don't seem to understand is that the suppco hard start kits are nothing more than a start capacitor and a start relay. They also don't understand the effect of combining capacitors, thinking that more is better, it isn't.
All of that said, forums are what they are and you just have to learn to weed out the good information from that is just posted because someone just wanted to jump in and post something.

I now have a Keystone Outback, but I try to help when I can.
