Absolutely agree !!! Everything MUST be kept PERFECTLY clean, and you'll still need a little luck. I'd suggest a rebuilt (Air Pro) or new from ackits.com. That's what I've used for the last decade on mine. Don't get a cheapie rebuilt one, you'll likely be sorry. And even if such is warranted, you'll waste the cost of your refrigerant and your time.
