I started to have issues with my C/A where low pressure was coming out of vents. I cleaned my coils, blower, vents but no luck. Had serviceman come out and check the freon and everything. He said that the capictor (sp) went bad and he replaced it. It worked for about an hour and the compressor started making a funny noise with low pressure air coming out again. He came back out and said the motor was bad and he ended up replacing motor and the fan. Well that worked for about an hour then the fan and motor died and all you can hear is rumbling noises. So he came back out and replaced the motor and said its faulty and put in another new motor. Well after about 9 hours its doing it again.. The compressor is covered under warranty but still what is causing these motors to burn up like this?? and the outside of our casing around our compressor was very hot to the touch.. Is there any suggestions that you all might have that I can pass on to the A/C guy? I appericate it, Thanks..

Hello Karma:
The technician needs to check the voltage at the unit with a volt meter and verify that the proper voltage is reaching the unit. He will also need to take an amperage reading to ensure that the motor is drawing the correct current.
Sometimes motors are bad out of the box. This is the end result of moving our manufacturing off-shore to countries who don't believe in quality.
As Fordman said, the contactor should be examined as well. They are inexpensive, and easily replaceable. Of course, if the contactor is bad, the compressor would not function either.
The condensing coils are hot because the heat is not being removed by the blower fan. In a pinch, you can put a sprinkler next to the unit and have it run a bit, but if you are in some areas, this may not be a permissible use of water. The water running will remove the heat in the condensing coil.
You say that you don't have pressure inside, did the tech replace the indoor motor, or the outdoor motor, or both? Do you have a variable speed, or a two- or three-speed indoor fan? Is the fan on the right speed for cooling?

That's a touogh one. I would say that you are getting ripped off and need a new AC technician. I wouldn't pay for that second new motor.
What you are saying doesn't make any sense. If it was the indoor blower, you compressor would more than likely be covered in sweat or ice. If it's the outside blower, it would not cause low pressure in your vents because that would not cause your indoor coil to ice up.
As far as why the motor keeps burning up....I have no idea except for something is not getting wired up properly.

YOU'RE FIRED ! ! ! make them pay for the damages that they've caused. This guy obviously don't know what he's doing, let him be full aware that if you have to call him back that you're going to call someone else too, or cal someone to troubleshoot it, In some cities it doesn't cost anything for an estimate on what they think is wrong. Also check out this guys credentials, he sounds like a flake.
To me it seems like there's a leak in the condenser or evaporator, the freon is overcharged, or is clogged or obstructed "if there isn't any free air it will get hot hot"
I'd really just suggest calling the company and having someone else come out to do the work this guy is obviously incapable of doing.

I'd check and see if the guy guarantees his work. Hold him accountable.
How old is the equipment? Is it possibly still under warranty?
Contact the manufacturer and tell them this ... they should be able to make recommendations and/or provide names of certified technicians in your area.
Obviously the guy you have working on your system really doesn't know what he is doing and he is experimenting. The manufacturer can probably give you a better referral to somebody who has been trained on your specific make and model.

I would look at the wiring going to the motor. Also check the relay contacts, they may be pitted and not making good contact and causing the motor to single phase.

sorry to say you need a new compressor sounds to me like mabe your dryer has a block in the line or your condensor moter not working caused the compressor to over heat.
