[QUOTE="Mr. Mach-ete, post: 12964043, member: 16424"] The service guy puts a hard start kit on your 7 year old 3 ton r-22 unit because the compressor is not running but the out door fan is, am I reading this correctly? Compressors that stop running that are open on the internal overload protector usually are not gettin sufficient super heated refrigerant back to the compressor. It's the refrigerant that keeps the compressor cool and keeps it running. If your unit is low on charge or the thermal expansion valve is starving the indoor coil for sufficient refrigerant your compressor will run hot. What if I told you your compressor may not be the issue but a symptom of a poorly operatiing TVX? Before spending $6,000 on a new system have another service company perform a superheat calculation with the refrigerant charge topped off. I would be willing to bet you have a TXV issue. Replacing a TXV costs $400.00, that's a lot cheaper than $6k! BTW, I'm a licensed Master HVACR contractor. [/QUOTE]
