carrier heat pump noisy start up
have 1 yr. old carrierheat pump model 25hbr336a0030010. when it starts it sounds like the whole unit will vibrate itself to death for 5 to 10 seconds. seems to run an abnormally long time no colder than it is. the installer has serviced it and says that everything is fine,that it is a scroll compressor is going into defrost and that they are noisy. is this a common problem with carrier? the way this thing sounds(wakes you up in the night) i dont see how a blanket around the compressor is going to stop the noise. any suggestions?

AC Compressor Noise
This residential compressor should be getting it's heat from one leg wired through a single pole contactor if someone has mistakenly replaced it with a two pole contactor or it is factory setup with a two pole contactor then it must have a crankcase heater that is working or liquid refrigerant will migrate to the bottom and cause major failure.
