Honestly, I don't think it really matters too much. The compressors are all made by Scroll and other than that it's just a box and a fan. Just get the highest efficiency model you can afford, that's where you're really going to notice the savings.
After that it just comes down to warranty (10 years is pretty standard).
Edit-If the box is close to a window of a room in the house that you use frequently you might want to spring for one of the more quiet ones. Ours is next to the garage though so who cares...

LOL "scroll" is a type of compressor (others are reciprocating, rotary, swash plate, centrifugal, etc.). Manufactures can be Copeland, Danfoss, Tecumseh, etc.![]()

Yes it's probably a Copeland.
Even though the compressor is the heart of the system coil designs as well as controls make a significant difference when it comes to reliability, operation under adverse conditions, and overall noise levels.
Indoor noise levels are up to the installer tie in methods AND the plenum design, air velocity and static pressure. Carrier's piston accurator many years ago on heat pumps was notoriously loud when the reversing valve was engaged for cooling. The hissing of the liquid line was easily heard in an adjacent room and alarmed people into thinking their system was leaking when they switched on their AC for the first time! :Q

The last house I was in had a GE heat pump that was like that. Except that it was loud every time the system powered down regardless of heating or cooling. I've heard noisy valves before, but that one took the cake.

I would say that problem is not corrected. You should hear mine! There is a setting for Quiet Shift in the Heat Pump settings accessed through the thermostat. It's not on by default, I guess I should try it.Originally posted by: Rubycon

Carrier. Nothing but good experiences with them.

Gas heat FTW. Trane for our setup.

Lennox or Trane?

I'm talking about reversing the refrigerant flow for defrosting purposes. Is that what you're talking about?

No, its a continuous noise when running in cooling only mode.
Yes the woosh! is going to be loud when the defrost cycle engages. The higher the differential between high and low side the louder it will be. It's loudest closest to the reversing valve which is enclosed in the outside unit but the sound can be heard along the lines running to the indoor coil as well.
