We ordered our Pinnacle with the "low profile" bedroom A/C and were very disappointed in the noise and vibration. As others have said, the lower ceiling in the bedroom contributes to the noise, but the unit itself was so noisy even outside that it was just unacceptable. Outside, the fan was so loud that it sounded like a jet engine. We had it swapped for the "conventional" style like the one in the living room and this made the bedroom much more livable even when sleeping. The higher profile does make the exterior vertical clearance a possible issue but only a few inches on ours when hooked up to the TV. Overall, it was a good solution for us.
