My unit quit blowing cold air, checked the outside unit and it was sucking air in from the top of the unit instead of blowing it out. Shut it off for the night to give it a rest and the next morning it would not operate at all. Called a repair company who told me I need a motor, capacitor, resistor and fan blades without seeing the unit and they could not explain the reversed air flow. Any ideas?

Time for you to call a different company and this time get a on site inspection and real estimate other wise you are just spinning your wheels.

If they told you that you need all of that over the phone, and without seeing the unit, I would suggest calling a different company. I have seen reverse rotation of condenser fan motor due to only a bad capacitor, (not common, but does happen). I have also seen this caused by a bad condenser fan motor. Of course, when you replace the motor you should replace the capacitor, just a rule of thumb (and caps are cheap, usually between five and thirty dollars). Fact is, you need to contact a company that will come out and trouble shoot the system, and only replace the parts that need to be replaced, and do the work that needs to be done to make the system operate correctly. I have been called to replace a complete central air system, because they had someone else come in and tell them that they needed a new system because their compressor was "shot". When I showed up at the home to calculate the new system, I found that the dual capacitor in the condenser unit was the only thing wrong with the whole system. Long story short. For under a hundred bucks I had their old system up and running just like it had for years and years, and saved them a few thousand. I hope you can find a tech that is in it for helping people, not making a killing off people. Now, don't get me wrong. You may have a major problem on your hands, but most likely its not a major issue, but may still cost you a pretty penny. I hope that it is a simple, cost effective fix. It really all comes down to hiring a reputable company to check things out. Good luck, and please do let me know the outcome.

Ha, you beat me, 1000, pretty much what I was trying to say in my mini novel, lol.
